How Poly Bags Are Made

If you’re considering poly bag packaging for your new product, it’s easy to see why! Poly bags are versatile, durable, and affordable. They’re also easy to customize to fit your product, as well as your brand, and their speedy production is perfect when you’re faced with a short lead time. 

It’s no wonder so many people choose poly bags for their packaging needs, but have you ever wondered how poly bags can feature so many great characteristics, yet be produced so quickly? Here’s a closer look at how poly bags are made. 

How Poly Bags are Made, Phase 1: Extrusion

Making poly bags starts with what’s called the blown-film extrusion process. This entails melting down small plastic pellets (resin) until they become molten and pliable enough to be pressed, or extruded, through a circular die gap. 

This extrusion forms a continuous tube of molten plastic that gets pinched off on one end and inflated to whatever size and thickness desired. The inflated tube is stretched vertically on a tower to cool, then flattened and wound onto a roll. Now it’s ready to be transformed into poly bags.

How Poly Bags are Made, Phase 2: Transformation

Once the blown-film extrusion process is complete and the plastic is on the roll, it can be fed through a machine that cuts and seals the plastic at a specified length, creating a poly bag. This process is repeated until enough poly bags are made to fulfill the order. 

Poly Bags are Made to Help You Succeed

Because poly bags are made in such a way that they can meet varying specifications of sizes and thickness, they can accommodate pretty much any packaging design and need. That means, no matter the size or shape of your new product, or how it’s transported and where, you can depend on the poly bag packaging to protect it. A product that goes from shelf to customer undamaged not only boosts customer satisfaction but also boosts your bottom line by reducing product failure and returns. 

In addition, the processes of extrusion, rolling, and cutting use automated machinery, allowing poly bags to be made efficiently and precisely, with very little waste. This saves time as well as money — a must for small to mid-sized businesses with ambitious revenue goals.  

Poly bags are also a cost-effective solution to display detailed branding logos and text, especially when compared to other packaging materials available on the market.

Finally, poly bags score major points for their fast turnaround time, too — a huge bonus when deadlines are looming, and often a key factor in a successful product launch.

How to Heat Seal Poly Bags

How to Heat Seal Poly Bags

Heat sealing poly bags is a great way to create an airtight seal with a neat, finished edge. It’s a cost effective way to package products because it requires no extra material to close the bag opening, just some equipment and the right heat sealable poly bags. Let’s explore what types of poly bags are ideal for heat sealing, and how to heat seal your own poly bags.

What are Heat Seal Poly Bags?

Heat seal poly bags are plastic bags that can be closed using a heat applicator, which fuses the material together to create a complete seal. Materials for heat seal poly bags can be separate pieces that are heat sealed together to establish the edges, or as a layflat tube, which is cut and sealed for products of different heights.

4 Advantages of Heat Seal Poly Bags

Heat seal poly bags are a great cost and time-saving solution to packaging for many manufacturing applications. Some advantages of heat sealing include:

  • Effective seal on bags of virtually any size
  • Watertight and airtight seal keeps out debris and moisture
  • Durable seal protects products during transit and handling
  • Clean, finished edge also displays contents in an attractive way

Types of Heat Seal Poly Bags

Almost any type of poly bags can be heat sealed, including polythene, polyethylene, and polypropylene bags. 

Low-density polyethylene, in particular, is ideal for making heat seal poly bags. This lightweight material melts at 320 degrees Fahrenheit, which means it can be heated, fused, and cooled quickly after the heating element is removed.

How to Heat Seal Poly Bags

To heat seal your own poly bags, you’ll need to start with the right materials and tools. Order custom poly bags from a reputable supplier and make sure they’re compatible with the heat sealing method you plan to use. 

  • Heat guns can be used to create an airtight seal on shrink wrap film for produce, parts, and other items. 
  • Impulse heat sealers apply heat and pressure to the poly bag for just a few seconds using an element wire.

Feed your poly bags into your heat sealing machine, and set the timer appropriately for the density of the material you’re using. 

The heat sealer melts the material until it co-mingles together, then sets it into a single, neat seam of plastic. As it cools, the poly material will contract, tightening the seal. 

Some heat sealing machines come with attached cutters, which trim the material close to the seal for an attractive finish.

If your facility must accommodate a high volume of heat sealing, consider investing in an industrial heat sealer, which can handle a variety of poly material types and different bag sizes.

6 Different Poly Bag Seals

6 Different Poly Bag Seals

When designing the best poly bag for your application, the poly bag seal is just as important as the poly bag type or material. There are many poly bag seals to choose from, including zip, heat seal, twist tie, fold and adhesive, and more. Let’s take a look at a few of the most popular poly bag seals and what different seals are used for, so you can decide which option might be best for your application. 

6 Popular Poly Bag Seals

No matter what you need to package, from agricultural items to auto parts, there’s a poly bag seal that will be perfect for your application.

#1 Twist Tie Poly Bags

This type of poly bag seals with a thin, flexible wire or ribbon which wraps around the bag opening and twists or ties to secure. The poly bag is open on one end and heat sealed on the other. It’s commonly used for packaging food items such as bread, potatoes, or loose bulk cereals and grains.

#2 Seal Reclosable Poly Bags

Seal reclosable poly bags are a popular choice because they allow for an airtight seal and repeated use. To open and close this poly bag seal, tracks on either side of the bag opening fit together, allowing the bag to be pressed close. A lip extends above the seal so it can be easily reopened by peeling the two sides apart. 

Seal reclosable poly bags can be used for a variety of items, and are typically used to hold small parts, especially those that can be stored and accessed again later.

#3 Zip Seal Reclosable Poly Bags

Similar to the seal reclosable poly bags, this poly bag seal also closes by bringing the adjoining tracks together. However, this type of poly bag seals using a zipper or slide. The zipper eliminates the need for extra material to be used as a lip. Zip seal reclosable poly bags allow more convenient, repeated access to the contents of the poly bag. 

#4 Fold and Adhesive Poly Bags

As one of the most cost-effective poly bag seals, the fold and adhesive poly bag seal is a popular choice. An extra lip of material extends beyond the bag opening, which is folded over the bag to close. A strip of adhesive secures the fold to contain the bag contents. This type of poly bag seal is not typically reusable, as it requires the bag to be torn open. Some poly bags with this seal option may have a perforated edge for easy access. 

A fold and adhesive poly bag seal is ideal for packaging items that need protection from dirt or debris, but aren’t meant to be airtight or puncture resistant. They are commonly used for packaging items like clothing or fabric, or can even be used as temporary storage for food items.

#5 Drawstring Reclosable Poly Bags

Drawstring reclosable poly bag seals use a simple cotton rope, threaded through a heat-sealed tube at the opening of the poly bag. To close, the ends of the rope are pulled tight. To open, the rope slides back into the tube as the opening expands. 

One advantage of drawstring reclosable poly bag seals is that the rope closure can double as a handle for easy transport. This type of reclosable poly bag seal is often used to package ice, as it can be easily accessed and reused.

#6 Heat Seal Poly Bags

Heat seal poly bags use one of the most basic sealing options. Once the poly bag is filled, a special device fuses the sides of the bag together, melting the material slightly and then allowing it to cool quickly to form an airtight seal. Heat seal poly bags can be used for almost everything, from protecting plastic cutlery to containing small parts to packaging medical devices.

To access the contents of the poly bag, the material needs to be cut or torn, which means it can’t typically be reused or reclosed. Heat seals for poly bags are commonly used for single-use packaging, where items need moisture-protection or to prevent contamination of sterile products.

What is Food Grade Plastic?

What is Food Grade Plastic?

Food grade plastic is plastic material deemed safe for use with foods. Plastic must meet strict requirements in order to be considered food safe, and is regulated by higher standards than plastic used for other purposes. Let’s take a closer look at food grade plastic, what makes it safe for food over other types of plastic and some examples of how food grade plastic is used.

What is Food Grade Plastic?

Food grade plastic must be produced using safe materials in a safe environment. For plastic to be used in contact with food or food products, it must:

  • Be protective: to act as a defense against moisture or contamination without breaking down 
  • Be durable: to protect food items during manufacturing, packaging, storage, transportation
  • Be chemically safe: to not contaminate food it comes in contact with. This means the plastic must have no tendency for “leeching”, or the potential for chemicals to seep into the food, where they could either affect the taste or cause adverse health effects for the consumer.

How Does Plastic Become Food Grade Plastic?

To be certified as safe and labeled food grade, the plastic must meet strict standards set by the Food & Drug Administration and other regulating organizations.

Food Grade Plastic Materials

First, the FDA must approve of the materials being used to manufacture the food grade plastic. They examine all ingredients and additives to ensure they are safe and will not affect the taste, odor, or color of the food. They will also test the materials for adverse responses to temperature changes, humidity and moisture, or the presence of other chemicals, oils, or alcohols. This verifies that the plastic will hold up for packaging, manufacturing or other uses.

Food Grade Plastic Manufacturing Facility

Secondly, the facility where the food grade plastic is manufactured must meet stringent cleanliness requirements and have good manufacturing practices in place to minimize potential risks of contamination of its products. Standards documents issued by the International Standards Organization regulate the environment of the manufacturing facility to ensure consistently high quality and clean products. ISO 9000 is the minimum standard with which most food grade plastic manufacturers must comply.

Food Grade Plastic Certifications

Lastly, once the food grade plastic has been used to make plastic film or bags to ship, store, or transport food, its quality will be checked again by the manufacturer and attributed with the correct certifications for food grade and safety. 

The Food Safety System Certification (FSSC 22000), established by the Global Food Safety Initiative (GFSI) is one example of a food safety certification for food grade plastic. With this certification, a quality management system is established for the food grade plastic product that continues throughout the product’s lifetime, from manufacturing to the end consumer, to ensure it is consistently high quality and food safe.

Uses of Food Grade Plastic

Food grade plastic is used in many applications, from the packaging and shipping of harvested crops to the supermarket, or the development and distribution of pharmaceutical products. Different types of plastic can be made food grade to handle different products or different environments. A few examples of food grade plastic include:

  • Polyethylene terephthalate (PET or PETE): plastic bottles or jars like single serving water bottles or condiment containers.
  • High-density polyethylene (HDPE): milk jugs, grocery bags, squeeze-dispenser bottles
  • Polyvinyl chloride: cling wrap, high clarity food storage bags
  • Low-density polyethylene (LDPE): produce bags, bread bags, can rings
  • Polypropylene (PP): clear wrappers, bottles for medication
  • Polystyrene (PS): plastic silverware, to-go containers

All of these materials (& more) can be made food grade to provide a safe material for food packaging, storage, and consumption. They are made in a strictly controlled environment to ensure that consumer safety remains top priority.

Looking for food grade plastic bags? A-Pac Manufacturing can help. From frozen foods to bread to produce like peppers and potatoes, we offer a variety of poly bags to suit any need. With custom printing also available, we can develop a custom food-grade poly bag for any company with any need.
