Types of plastics

PET PETP (polyethylenterephthalate) is light-weight, stiff, rigid, fracture-proof, aroma-tight and transparent like glass. Collected and ground PETP bottles are a sought-after basic material for the manufacture of a great number of different products.

HDPE HDPE (high-density polyethylene) is harder and stiffer than LDPE (low-density polyethylene). Withstanding higher temperatures and highly resistant against chemicals, it is used for all kinds of bottles (shampoo, detergents, etc.) as well as for cans, buckets and beverage boxes.

LDPE LDPE (low-density polyethylene) is the most used plastic material for packaging, e.g. for all kinds of foils and plastic bags. LDPE is extremely resistant against chemicals, almost tight against water vapour and is odourless and taste-neutral.

LDPE packaging

 

PP PP (Polypropylene) is oil and grease resistant. It has a very low permeability for water and oxygen. Consequently, it lends itself for packaging margarine, edible oils, mayonnaise, ketch-up, mustard, salad dressings, savoury biscuits, bread, cakes and pastries. In most cases, screw caps of PET and HDPE bottles are made of polypropylene.

r6 PS (polystrene) is used above all for yoghurt and cream pots.

r6 EPS (expanded polystrene) is known under the trade name “Styropor”. Used as packaging material it protects fragile products and devices susceptible to shocks.
