What Is Contract Packaging?
Developing your own packaging system involves much more than investing in the right packaging equipment and materials to get the job done. It also involves warehousing and hiring an additional workforce to run your packaging operation alongside your core business. To many companies, setting up their own packaging line is simply not feasible in terms of both the cost and labor required.
This is where contract packaging comes in. Also called co-packing, contract packaging is when a business hires the services of a packaging company to oversee its packaging, assembly, kitting, warehousing, and other supply chain needs. The contract packager can be a specialist in a certain type of packaging—like shrink wrapping, corrugated cardboard, or bottling—or offer additional services like printing, packaging design, and testing.
Here we’ll discuss how food contract packaging in particular works, as well as the benefits of outsourcing your packaging needs.
How Does Food Contract Packaging Work?
Because of the strict industry standards of food processing and packaging, a contract packaging partner in this field must have the equipment, expertise, and materials necessary to protect the integrity of your food products while meeting these standards. Most food co-packing processes involve these three main steps.
Step 1: Discuss Goals
After identifying your co-packing needs, the first step is to reach out and discuss your product and goals with the co-packer. Some companies may require you to complete a questionnaire to learn more about your product and understand your expectations. You will sign a non-disclosure agreement before proceeding to the next phase.
Then you will send your samples and recipes to the co-packing company, which will then analyze your products to ensure they are compatible with its production equipment. If they are, the co-packer will take you through the various packaging options, including materials and quantities. A good contract packaging provider will know how to make the most efficient use of packaging materials while maximizing the shelf life of your product.
Step 2: Approve the Test Batch
Before going into mass production, the co-packer will send a test batch for you to evaluate. You will also get product information that will include:
An allergen statement
A net weight declaration
An ingredients list
A nutritional facts panel
Once you approve the final details and design of the packaging, the co-packer commences printing the packaging materials.
Step 3: Production
The company will begin production using your finalized recipe, packaging design, and materials. They usually have production minimums that range from hundreds to thousands of units, so consumer demand for your product must be high enough to save you money per unit.
Why should you hire a contract food packing provider? There are many advantages of outsourcing your packaging needs. For example, a co-packer will offer the machinery, labor, and thought leadership required to deliver your products to the market in style. This allows you to focus all your energy on your core business—manufacturing your product. Other benefits of hiring a co-packer include high-quality packaging, cost reduction, and efficient management of your packaging line.
Co-Packing vs. Contract Packaging Services
Co-packing is the same as contract packing—they involve outsourcing the primary and secondary packaging of finished goods to a third party. While co-packing is common in all industries, it is most prevalent in the health and beauty, food and beverage, and medical and pharmaceutical fields.
Choosing the Right Contract Packing or Co-Packing Partner
There are a few things you should take into account when looking for the right co-packer for your food products, such as:
Fast lead times
Finding the right co-packer can be overwhelming, especially if you are new to the market or want to venture into a new field. Econo-Pak is a third-generation family-owned contract packaging company dedicated to serving the unique needs of the food processing, pharmaceutical, and retail industries.

Click to Expand
Product packaging is an essential step in the product life cycle. It not only protects the product from external damage but also serves as an essential marketing tool. Packaging can help a product stand out from the competition. It can also provide information about a product’s features and benefits. In this article, we’ll explore the key properties to look for when selecting suitable material for packaging your products.
How Do You Properly Select Packaging Materials?
There are many factors to consider when determining the best packaging material for your product. Here are five typical considerations in the selection of proper product packaging materials:
Cost: The cost of the packaging material is an important factor to consider when selecting the best product packaging material. Some materials used for packaging can be relatively costly when trying to meet specific industries’ aesthetic standards or durability needs. It’s important to ensure you’re getting good value for your money.
Durability: It’s a good idea to understand the product you intend to buy before placing an order. If you skip this step, you may end up with subpar packaging supplies that aren’t optimal for your needs. Select packaging materials that can withstand the rigors of the shipping process and protect your product during transit.
Eco-Friendliness: Many businesses are switching to eco-friendly packaging materials to reduce their environmental footprint. Consider recyclable and sustainable materials, to help your business maintain a positive environmental record.
Customization: Aim for packaging materials that you can customize to meet your specific needs. Select packaging materials that you can brand with your company’s logo and colors. This will help your product stand out from the competition.
Security: The packaging material needs to be strong enough to protect your product from damage, tampering, or theft. Choose a material that can provide a secure seal and protect your product from any potential security issues.
Food Packaging Material Selection Considerations
Selecting packaging for food products comes with additional requirements and standards. Here are the key considerations when selecting packaging materials for food products.
Functionality and Safety
The primary considerations when selecting packaging materials for food products are functionality and safety. The packaging materials should be able to protect the food from contamination, spoilage, and other external factors. It should also be able to withstand harsh shipping and storage conditions while maintaining the product’s freshness and flavor.
Food Packaging Design
The design is also vital when choosing packaging materials for food products. The packaging materials should effectively convey the brand message and aesthetic. Chose a design that will capture the attention of potential customers and stand out on store shelves.
Your packaging material should be able to communicate the brand’s message and values to its target audience effectively.
When selecting packaging materials for food products, it is also essential to consider the needs of e-commerce customers.
You may need to ship products for very long distances in this scenario. In these cases, consider an easy-to-store and easy-to-ship packaging material to lower the shipping costs. Your material should also be easy to open and recycle for the recipient.
Choosing A Suitable Food Packaging Manufacturer
Selecting a food packaging manufacturer requires careful research and due diligence. There are several factors to consider, including material choices, fast lead times, ISO certifications, quality, transparency, and control. It is also important to choose a supplier with a good customer service record and proven reliable experience.

Posted by Econo Pak on | Comments Off on What Plastic Is Used in Shrink Wrapping?
For more than 40 years, Econo-Pak has provided customers with top-quality packaging materials for a diverse range of applications. As a trusted supplier of quality materials, we offer shrink wrapping materials suitable for packaging and protecting a countless array of products.
Three primary types of shrink wrapping exist for various applications in the shipping and retail industries, among others. These include polyolefin (POF), polyethylene (PE), and polyvinyl chloride (PVC). Each type of material comes with unique properties and benefits.
What Is Plastic Shrink Wrap Made Of?
The three types of shrink wrap materials offer different advantages that make them compatible with various applications. The following are the specific characteristics of each:
PVC Shrink Wrap
While PVC shrink wrap used to be the most popular shrink packaging material used for many applications, in recent years, its lack of sustainability and potential health hazards have made it less common than POF and PE shrink wrap materials. However, many applications still use it across multiple industries, with these materials composing the following:
And other packaging materials
POF Shrink Wrap
POF shrink wrap is considerably safer than PVC shrink wrap and offers superior versatility and durability compared to other shrink wrap materials. Its food-safe nature has led the FDA to approve it for use in many applications. POF shrink wrap consists of polyolefin, which provides reliable protection for a wide variety of products, including those with an irregular shape. This material is also cost-effective and puncture-resistant, further contributing to its popularity.
PE Shrink Wrap
For applications requiring more flexibility than polyolefin shrink wrap but with the same level of durability, PE shrink wrap offers a dependable alternative. Polyethylene is a kind of polyolefin with added ethylene that allows for increased flexibility, making it ideal for shrink wrap and stretch wrap materials. Low-density polyethylene (LDPE) and high-density polyethylene (HDPE) are available, with the increased durability and strength of LDPE offering more reliability for shrink wrap materials.
The Difference Between Shrink Wrap and Stretch Wrap
Although people often confuse plastic shrink wrap and stretch wrap because of their similar appearance, they each feature unique properties that result in differences in performance. In shrink wrap applications, packaging equipment places a thin film of PE over one or more products. The system then applies heat to the film, causing it to shrink over the items and forming a protective seal that’s resistant to tampering and tears. Stretch wrap applications, on the other hand, rely on a different type of formulation to allow for enhanced stretching.
Stretch wrap offers elastic memory and self-clinging capabilities to form a tight protective layer around products. It’s often used for unitizing or palletizing several products on pallets to keep them stable during transport. Another key difference between shrink and stretch wrap is the stretch limit before breakage occurs. For shrink wrap, this limit is a 50-75% stretch while stretch wrap can stretch to around 100-300% before breaking.
Why Polypropylene Is Less Used for Shrink Wrapping
Many applications forgo the use of polypropylene for shrink wrapping due to its increased hardness compared to other materials. Additionally, shrinking polypropylene leads to decreased stability and it has a higher melting temperature than other more reliable materials.

Posted by Econo Pak on | Comments Off on What Materials Are Used in Flow Wrapping?
Econo-Pak is a contract packaging service provider specializing in the creation of functional and attractive packaging solutions for food, pharmaceutical, retail, and specialty applications. Our packaging services include flow wrapping, a continuous, high-speed packaging process that encloses products in a clear or printed film.
During the flow wrapping process, a conveyor belt moves the product horizontally to the forming area. The product is then wrapped in film and sealed at both ends by applying pressure, heat, or a combination of both. Similar to vertical form fill seal (VFFS) methods, the finished result is a flexible pouch secured by airtight crimp-sealed ends.
What Materials are Used with Flow Wrapping?
The flow wrapping process is compatible with the same types of materials used in VFFS methods. When choosing a material for a packaging application, it is important to prioritize product safety and quality while considering the type of packaging aesthetic that will best promote the brand and engage the target consumer. Common flow wrap packaging materials include:
Polyethylene terephthalate (PET): A member of the polyester family, PET is a durable and transparent thermoplastic polymer resin. This lightweight yet strong packaging material is ideal for protecting items from their surroundings while allowing the consumer to view the enclosed product.
Polyethylene (PE): PE, a type of polyolefin resin, is the most widely used consumer plastic today. This transparent, glossy material makes an attractive and protective package that maintains the integrity and freshness of the product during transportation and on the store shelf.
Metalized film: Metalized films are metal-coated polymer films with a shiny metallic appearance. In food packaging applications, these films offer reliable protection against water and oxygen permeation while conveying a high-end aesthetic.
Poly film: Poly film is a thin, transparent polymeric packaging material that prevents contamination and extends the product’s shelf life.
Polypropylene: Polypropylene is a thermoplastic polymer in the polyolefin family. This clear, glossy material is suitable for packaging everything from sensitive pharmaceutical and medicinal products to perishable food items.
How Does Flow Wrapping Work?
While the flow wrapping process can be customized for various applications and materials, all flow wrapping machines generally consist of the same elements:
Infeed conveyor system
Film feed assembly
These elements work together to continuously transport, wrap, seal, and discharge the packaged products. Individual steps of the flow wrapping process include:
Process initiation: The unwrapped products are placed on the infeed conveyor belt, where they are transported to the forming area.
Wrapping: The flow wrapping machine wraps the product in the sealing material and mates the two outer edges of the material.
Sealing: Two rotating fin seal wheels form a longitudinal seal along the mated edges using heat, pressure, or a combination of both.
Cutting: Using rotating cutting heads or end seal crimpers, both ends of the adjoined packages are simultaneously sealed and cut to produce several individual packages.
Delivery: The packaged products are transported to the discharged area.
What Types of Products Are Ideal for Flow Wrap Packaging?
Compatible with a wide range of product shapes and sizes, flow wrap packaging can be used for essentially any solid item that can be transported along a horizontal conveyor belt. Small granular items or liquid products are generally better suited for vertical packaging techniques that allow the product to be dropped into the package.
Examples of commonly flow-wrapped items include:
Candy and confectionery products
Dry products such as pasta, rice, and seeds
Meat, poultry, and seafood
Pharmaceutical and medicinal items
Industrial products such as tools and hardware
Personal care items and cosmetics

Flexible packaging has significantly grown in popularity in the food and beverage industry. Due to its many benefits, it is often the packaging of choice for various food products on a domestic and global level.
Flexible Food Packaging
(Click to Expand)
By using non-rigid materials to package food, manufacturers are better able to customize the container to fit the product and the brand. Flexible packaging is available in a variety of shapes, sizes, and materials, and it can be created in either formed or unformed configurations. Formed packaging is pre-shaped and can be filled and sealed in-house, whereas unformed packaging comes on a roll that is sent to co-packers for forming and filling.
Types of flexible packaging include:
Sample Pouches. These small heat-sealed packets are usually pre-formed for easy in-house packing and filling.
Printed Pouches. These are sample pouches that have been customized with branding information for marketing purposes.
Sachets. These flat packets are common for single-use pharmaceuticals and personal care products. They are also ideal for sample sharing in-store and at trade shows.
Printed Roll Stock. These arrive in an unformed roll that is already printed with product and branding information. The co-packer forms, fills, and seals them.
Stocks Bags. Stock bags are blank formed bags or pouches. They can be used as-is or you can add a label with branding and product information.
Flexible containers offer incredible versatility and flexibility. This is important in the food and beverage industry as companies strive to differentiate their products in a competitive space while ensuring the items stay fresh and protected from damage.
Benefits of Flexible Food Containers
Flexible packaging offers a number of benefits, including:
Consumers Love It. Flexible packaging is extremely consumer-friendly. Upright flexible pouches make it easy to access snacks or baking ingredients, while resealable packaging ensures freshness, prevents spills, and keeps out contaminants.
Simplified Shipping and Handling. Lightweight flexible packaging is easier and more cost-effective to transport. This not only helps you save money but also reduces your carbon footprint due to less fuel consumption.
Customizable Barrier Properties. Custom films and other barrier materials can protect your product from light, air, or moisture.
Good for Branding. From custom graphics that highlight your brand to clear windows that allow consumers to see the product inside, flexible containers are easily customized for effective branding.
Environmentally Friendly. The amount of greenhouse gases used to produce flexible packaging is lower compared to producing traditional packaging materials.
Increased Shelf Life and Freshness. Barriers and resealable openings keep out UV light, moisture, dust, and more to ensure the product stays fresher, longer.
Lower Production Costs. Flexible packages are easier to form and require less material than rigid packages, reducing production time, waste, and energy consumption.
Flexible Packaging Industries
Along with the food and beverage industry, many other industries benefit from using flexible packaging. These include:
Cosmetics. Resealable packages can be used for cotton pads and make-up removing wipes while flexible sample pouches can be used for foundation, concealer, lotion, and serum.
Personal Care. Sample pouches are ideal for single-use medications and personal products.
Household Cleaning. Flexible packaging offers an ideal solution for single-use detergent packets, cleaning powder, and more.

There are many types of packaging methods available, each of which is suitable for different packaging needs. Flow wrapping and overwrapping are two of the most commonly employed by industry professionals for consumer goods. The following blog post provides an overview of the flow wrapping and overwrapping processes, outlining what they entail, unique benefits, and typical applications.
Understanding the Processes
Despite their similarity in name, flow wrapping and overwrapping are distinct packaging techniques; they package different types of products, employ different equipment, and achieve different functions. Below we describe each process and the differences between them.
An Overview of Flow Wrapping
Flow wrapping, also sometimes referred to as pillow pouch wrapping, horizontal bagging, and fin-seal wrapping, is a horizontal-motion packaging process used to cover products—with any geometric shape—in clear or custom-printed polypropylene film. The finished package is a flexible packet featuring a crimped seal on each end.
The flow wrapping process employs the use of flow wrapping machines, which are designed and manufactured to package a wide range of products to achieve varying aesthetic looks and feels. Using these machines, the following operations occur:
Placement of the products on an infeed conveyor belt
Transportation of the products to the forming area
Wrapping of the product(s) with sealing material
Mating of the outer edges of the material along the bottom
Creation of a tight seal between the mated edges using pressure, heat, or both
Movement of the products through rotating cutter edges or end seal crimpers to seal both ends and separate individual packets from one another
Discharge of the packaged products for storage and/or further packaging operations
An Overview of Overwrapping
In contrast to flow wrapping, overwrapping is only used to wrap and seal products with flat sides—such as boxes, cartons, and trays—in heat sealable film. The end result is a packaged product wrapped and sealed, much like a gift. The process is suitable for adding secondary packaging over already packaged products to preserve freshness and combining individually packaged products together.
Similar to flow wrapping, overwrapping makes use of specialized equipment—i.e., overwrapping machines. These machines perform the following operations:
Pushing the product through heat sealable film cut from a larger roll
Folding the film around the product
Heat sealing the film at the overlapping sections
Forming the envelope-like ends with shaped plates and sealing them using heated plates or belts
Discharging the packaged products for storage and/or further packaging operations
Differences Between Flow Wrapping and Overwrapping
When deciding between the flow wrapping and overwrapping for a packaging operation, it is important to keep in mind their differences. For example, flow wrapping accommodates products of all shapes, while overwrapping is suitable only for products with flat sides. Additionally, flow wrapping is used to protect products from damage and degradation, while overwrapping allows for the combination of multiples packages into a single unit for easier storage and delivery.
Which Method Should You Choose?
Both flow wrapping and overwrapping offer unique advantages, but there are times when it’s clearly best to use one over the other. Below we outline some of the key benefits and applications of each packaging technique.
Benefits and Applications of Flow Wrap Packaging
Some of the benefits of using the flow wrapping method to package products include:
Broad size tolerance: Flow wrapping accommodates a variety of product shapes and sizes.
Airtight seals: The seals formed by the flow wrapping process keep out air and moisture to preserve the freshness of the packaged products, resulting in longer shelf lives.
Easy set-up operations: With flow wrapping machines, it’s easy to adjust for different product parameters, including in regard to size and shape.
For the above reasons, among others, flow wrapping is widely used across industry. It is often used by the food and beverage, medical, pharmaceutical, and tool and hardware industries to package their goods, such as candy bars, baked goods, soaps, lotions, and duct tape.
Benefits and Applications of Overwrap Packaging
Overwrapping offering many manufacturing advantages, such as:
Versatility: Overwrapping can be used in several ways, including serving as the primary packaging for the products, as a method of bundling separate products into a single multi-pack unit, or as further protection for already packaged products.
Attractiveness: Overwrapping creates a sleek packaged look.
Tamper-proofing: As overwrapping requires specialized equipment to apply correctly, it’s obvious if it has been tampered with or removed.
Compound control: Overwrapping keeps out contaminants (allowing for longer shelf life) and keeps in internal compounds (helping contain strong odors).
Many consumer industries make use of overwrapping. Some of the most common include the food and beverage, healthcare, and personal care industries, which use the process to package goods such as frozen meat, boxes of tea, paper towels, cold medicine, and lipstick.
