摘　　要：针对牛奶包装用聚乙烯共挤薄膜(PE)进行了热收缩曲线的测定,确定了对于共挤薄膜的热封温度应取温度收缩曲线的1阶段作为上限,并在保证封口强度的基础上,应减少热封时间,可以有效地减少破损率,保证封合处的表面美观。This article determine heat shrinkage curve of the polyethylene film （PE） which for milk package, And the article confirmed that the temperature shrinkage curve 1 stage should le taken as the temperature upper limit for film heat-sealing, Producer should reduce the heat- sealing time under the condition of heat-sealing intensity, This may effectively reduce damaging rate and keep heat-sealing plastic surface to be fine.

关 键 词：热封强度 热收缩 收缩率
