摘要

method of manufacturing film szeu015bciowarstwowej method wspu00f3u0142wytu0142aczania with rozdmuchem standard ekstruderze trzywarstwowym, characterized by that a mixture of the composition of 65% low density polyethylene ldpe, 25% linear low density polyethylene mlldpe c6 and 10% initiator adhesion,forming additive containing polibuten at concentrations of 50% propane or copolymer from 11% in low density polyethylene ldpe, is rozdmuchowi with a bur 2.8, is in the process of extrusion of linear speed of 17 m / min, after which the pre cooling temperature from 55 to 60u00b0c,laminacji subjected by niechu0142odzonego kalandra of upper working pressure from 7 to 9 atm., then cools to ambient temperature and trying to foil paper cores or pvc.
