Structure and properties of polyolefin-based multilayer films for healthcare applications and management of quality control

Different blends of various grades of polyethylene (low density PolyEthylene (LDPE), linear low density PolyEthylene (LLDPE) and medium density PolyEthylene (MDPE), specialty of etherophasic copolymers propylene-ethylene and inorganic additives, as talc and calcium carbonate, were used for the production of multilayered films for healthcare applications. These films were obtained through the blow extrusion process using a pilot plant at company Blu Plast. This study was aimed to the improvement of the characteristic of soft-touch and mechanical performance of films used as back-sheet, whitout resorting surface treatment. Moreover, the management system of quality control of the company Blu Plast was implemented.
