发明名称 MULTI-LAYER POLYESTER/POLYOLEFIN SHRINK FILM
摘要 <p>The multi-layer polyester/polyolefin shrink film of this invention provides a combination of shrink tension, hot seal strength, sealability and shrink temperature range heretofore unobtainable in an oriented, monolayer polyolefin material. The preferred film has five layers in which the middle layer comprises a polyester or copolyester, two inner layers adjacent the middle layer comprise ethylene-vinyl acetate copolymer, and the skin or outer layers comprise an ethylenepropylene copolymer.</p>
