Plastic bags also called “poly bags” are shaped like two identically-sized rectangular plastic sheets (usually less than 250 micron thickness) fused together on three of the sides, with one side left for the opening.

How it is made?
Most Plastic bags are made from polyethylene – more commonly known as polythene.
- Low density polythene (LDPE): has the most excessive branching. This causes the low density to have a less compact molecular structure which is what makes it less dense. It has a density of 0.91-0.925g/cm3.
- High density polythene (HDPE): has minimal branching of its’ polymer chains. Because it is denser it is more rigid and less permeable then the LDPE. It has a density of 0.941-0.965g/cm3.
- Liner low density polythene (LLDPE): has a significant number of short branches. This gives LLDPE higher tensile strength and higher impact and puncture resistance than the LDPE. It has a density of 0.91-0.94g/cm3.
- Medium density polyethylene (MDPE): has a little less branching then the HDPE. It is less notch sensitive then HDPE and has better stress cracking resistance. It has a density range of 0.926 – 0.94 g/cm3
The most common way to produce plastic bags is in 3 steps: blown film extrusion, printing (optional) and converting.
