What raw materials are extracted and processed to make plastic bags?

The first step of making plastic bags is to extract the raw material. This material — polyethylene —can be derived from either cracked natural gas or refined oil. Because these hydrocarbons are located below ground, they must be reached and extracted through the use of drilling wells.

What are the raw materials for plastic bags?

Extraction and processing of raw

Plastic is made from hydrocarbons obtained from crude oil. The crude oil requires processing by way of fractional distillation, followed by cracking and polymerisation.

What process is used to make plastic bags?

Plastic bags are made by a process called blown film extrusion. Polyethylene pellets are melted down, blown into a thin material, and manufactured into bags.

What type of plastic is used to make plastic bags?

Low-Density Polyethylene Plastic Bags

Low-density polyethylene (LDPE) resins are typically used in the creation of plastic bags for food packaging and in the manufacturing of utility bags. The LDPE polymer is manufactured with short, branched chains that are widely spread and are of low density.

What polymer are plastic bags made of?

The plastic bags people are most familiar with are generally made from polyethylene. This consists of long chains of ethylene monomers which are derived from natural gas and petroleum.

What are the materials used to make plastic?

Plastics are derived from materials found in nature, such as natural gas, oil, coal, minerals and plants.

Where are plastic bags made?

Tiny beads of polyethylene resin serve as the building blocks for plastic bags. Manufacturers purchase millions of pounds of polyethylene resin each day, often from areas where oil and gas production are prevalent, like East Texas and Central Pennsylvania.
