How are polythene bags made?
It involves superheating and pressurizing raw LDPE, HDPE, or LLDPE plastic pellets to create a consistent molten liquid. Once the liquid is created, the resin is forced into a circular die. Then the hot resin is blown outward or upward to create a thin, long balloon of very pliable plastic film.
How do you manufacture polythene?
The process by which polythene film is manufactured is known as blown film extrusion, or extrusion for short. At Polybags, raw polymer is distributed from our storage silos via a feeding machine called a hopper into the machine that creates the polythene, which is called an extruder.
How is plastic bag made step by step?
Plastic bags are formed through a process called “Blown Film Extrusion”.
- Mixing. Various densities of polyethylene are mixed together to form a homogeneous mixture consisting of low density and high density polyethylene.
- Melting.
- Pumping air.
- Pass through rollers.
- Heat-seal and cutting.

What are the materials used to make polythene bags?
Traditional plastic bags are usually made from polyethylene, which consists of long chains of ethylene monomers. Ethylene is derived from natural gas and petroleum.
What raw materials are used to make plastic bags?
Plastic bags are made from polyethylene, which begins as ethylene extracted from natural gas or oil. It is specially treated to become a polymer. Polyethylene is changed to fit how it will be used and the different types of bags to be produced.
What are the ingredients in plastic bags?
Plastic bags are made out of “film”, or thin flexible sheets of plastic. Most plastic bags are made from polyethylene resin code #2 or #4. Resin code #2 is high density polyethylene (HDPE). Resin code #4 is either low density polyethylene (LDPE) or linear low density polyethylene (LLDPE).
How are bags constructed?
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.
