How Plastic Bags Are Made: From Raw Material to Final Product?

Plastic bags are one of the most commonly used packaging materials across industries, including groceries, retail, industry, and medicine. Have you ever wondered how these kinds of bags are manufactured? At A.N.S. Plastics Corporation, serving New Brunswick, NJ, with pride, we specialize in manufacturing higher-quality plastic bags. We would like to take you through the process of how a plastic bag is produced—from raw materials to the product in your hand.

1. Obtaining The Raw Materials

A plastic bag begins with a simple ingredient: natural gas or petroleum. These fossil fuels are refined into a substance known as naphtha, which is then processed to create polyethene—the most frequently used plastic to produce bags.

There are two types of polyethene employed primarily:

  • High-Density Polyethylene (HDPE): Light and resilient and is ideal for grocery and retail bags.
  • Low-Density Polyethylene (LDPE): More elastic and extensible. It is used in bags for food and products.

We at A.N.S. Plastics Corporation works in partnership with reliable suppliers to procure quality polyethene resins. This ensures that all our products are consistent, durable, and effective.

2. The Extrusion Process

Once we have the polyethene resin pellets, the process of extrusion gets underway. This is where the plastic in its raw form is shaped to become a film.

How It Works:

  • Resin pellets are fed into an extruder, a large machine that contains a screw that turns inside a heated tube.
  • As the pellets warm, they turn into molten, heavy plastic.
  • The plastic that has melted is forced through a circular opening, creating a long, thin tube of plastic, which is referred to as a bubble.

This plastic bubble is air-filled to maintain its shape and is rapidly cooled, typically by the use of air rings. It is then pressed flat between rollers into a lay-flat tube once cooled.

3. Printing (Optional)

Branding matters to most customers in New Brunswick and elsewhere. It is in light of this that A.N.S. Plastics Corporation offers customized printing during the manufacturing process.

We apply flexographic printing to place logos, designs, directions, or marketing messages directly on the film. It is used before the plastic is made into bags and serves to provide bright and long-lasting print quality that is good during product usage.

Whether you are a local business looking to brand yourself or a restaurant looking for custom take-out bags, our design team will collaborate with you to make your vision a reality.

4. Sealing and Cutting

The flat tube passes through machines that seal and cut the film into individual bags. Sealing and cutting will differ depending on the type of bag being produced—flat, gusseted, or T-shirt.

At this point, options are:

  • Handle punching
  • Bottom sealing
  • Side flaps
  • Perforation lines

They are incorporated based on what our customers need. The new equipment ensures measurements and seal strength are accurate, which is very important to the way the product works.

5. Quality Control

Quality control at A.N.S. Plastics Corporation is strictly accorded importance. Each batch of bags is inspected for:

  • Strength and toughness
  • Seam strength
  • Print Quality
  • Size accuracy

Our New Brunswick, NJ, plant is held to strict quality standards. This guarantees we meet industry requirements and provide our customers with satisfaction in every order.

6. Packing and Sending

After approval, the completed plastic bags are packaged and shipped. The bags are shipped based on what the customer needs:

  • On rolls (for automatic dispensers)
  • Flat-packed
  • In cartons

We serve various businesses in New Brunswick, such as local stores, grocery stores, restaurants, industrial wholesalers, and municipal organizations. Our delivery system is adaptable to small and large orders and delivers them timely in New Jersey and surrounding states.
