LDPE 90-10

LDPE is a thermoplastic which is obtained from petroleum. It is a semi-rigid and translucent polymer. It has a density of 0.910-0.930g/cm3. The LDPE structure consists of bundled polymer chains which are placed in an irregular shape. It is perfectly flexible, it can be used at the temperature between −50 °C and 80 °C. The melting point of LDPE is about 120 °C.It is generally used for trays and pots, long life bags and sacks, poly tunnels, protective sheeting, food bags etc. It is also used in wire & cable covering, computer parts such as disk drive, video cards. shrink wrap and container lids.

The effect of gamma radiation (doses 5–60 kGy) on the thermal, mechanical and permeation properties, as well as on IR-spectra of experimental five-layer food packaging films were studied. Films contained a middle buried layer of recycled low-density polyethylene (LDPE) comprising 25–50% by weight of the multilayer structure. Representative films containing 100% virgin LDPE as the buried layer were taken as controls.

Results showed that the percentage of recycled LDPE in the multilayer structure did not significantly () affect the melting temperature, tensile strength, percent elongation at break, Young's modulus, oxygen, carbon dioxide and water vapour transmission rate values and the IR-spectra of the non-irradiated and irradiated multilayer films. Irradiation (mainly the higher dose of 60 kGy) induced certain small, but statistically significant () differences in the mechanical properties of multilayer films (with or without recycled LDPE layer) while no significant differences were observed in the thermal properties and in the gas and water vapour permeability of multilayer films.
