摘要: A heat-shrinkable bag has a means for initiating manual tear that can be propagated to open the and allow product readily removed therefrom, without use of knife or scissors any other implement. The is made from multilayer film having Peak Load Impact Strength at least 50 Newtons per mil. tearing results in first side bag, second bag. are each capable being manually through heat seal across down length with an opposite edge, so inside package process making opening package, comprises placing sealing closed, shrinking around product, propagating tears, removing
