HEAT-SHRINKABLE FOAMED FILM FOR LABEL OF GLASS BOTTLES AND METHOD OF PREPARING SAME

摘要

A heat-shrinkable foamed film for a label of glass bottles is provided to reduce manufacturing and delivery costs by forming a base film having cushion property. A shrinkable foaming film(10) has a cushion property so that it protects a glass bottle from an external impact. A heat shrinkable foaming film has enough shock resistance and a printability which is the requisite for being used as a label, seaming property, and a standard stability. A manufacturing method of the heat shrinkable foaming film includes a process of mixing a polystyrene resin with a foaming agent and manufacturing the basic film promulgated with an extrusion method.
