Micron or micrometre is unit of measurement indicating the material thickness of foils and films (e.g. aluminium foil, freezing bags, garbage bags). 1my = 1/1000 mm
Polystyrene is a type of plastic produced by polymerization of styrene. It is transparent and has tough, firm and gleaming properties. Products made of PS: e.g. champagne glasses, shot glasses, cutlery.
High density polyethylene is also known as low-pressure polyethylene. The foil or film made from this material is very thin, feels firm, and makes a rustling sound. Products made of HDPE: e.g. garbage bags, breakfast bags.
Polyethylene is a type of plastic produced by polymerization of ethylene. It is transparent and has tough yet flexible properties. PE has a variety of applications for packaging foils and films. Products made of PE: e.g. freezing bags, garbage bags, garbage sacks.
Low density polyethylene is also known as high-pressure polyethylene. Foil or film made of this material is stronger and feels more softly. Products made of LDPE: e.g. freezing bags, garbage sacks.
Polypropylene is a type of plastic produced by polymerization of ethylene. It is very similar to PE, but more heat-resistant. Products made from PP: e.g. drinking cups, menu plates, soup tureens.
