MULTI-LAYER LAMINATE PLASTIC

摘要

The present invention belongs to the field of producing flexible materials consisting of a plastic film sandwich for the production of bags, suitcases, sofas and chairs covering, furniture and clothing. Multi-layer laminated plastic is realized by the combination of three overlapping components: a first and third layer component consists of a polyester film coloured on one side and glued by laying a bi-component polyurethane adhesive film having a weight of 2 grams per square meter, and a LDPE film (Low Density Polyethylene) having a thickness of 35 microns and a weight of 32.2 grams per square meter; a second layer component, placed between the first and the third component, is made by extruding two LDPE films (Low Density Polyethylene) and heat-sealed with a form-roller, by forming air bubbles inside;
