Polyolefins polyethylene agricultural films

Their mechanical properties are comparable with those of conventional polymers (Clarinval, 2002). There are flexible materials with medium service temperature like polyethylene (PE), relatively stiff materials with medium service temperature like polystyrene (PS) and stiff materials with a high service temperature like polyethylene terephthalate (PET). Table 1.4 gives a comparison of the typical properties of biopolymers with those of polyolefins. The main applications are in the fields of industrial and domestic packaging, bags, fibres and textiles, agricultural films, catering and fast-food, toys, leisure, medicine, hygiene and cosmetics (Weber, 2000 Kab, 2002 Kolybaba et al., 2003).
