摘要： A packaging material is composed of a heat resistant base layer, a sealant layer, and a resin layer disposed at least a portion between the heat-resistant base layer and the sealant layer. The resin layer is composed of a resin material having a predetermined strength in a non-heated temperature state of less than a room temperature and this strength is lowered in a high temperature state heated, for example, by a microwave oven. Such packaging material can be effectively utilized for many kinds of packaging bags or containers with the sealant layer being disposed to the inner content side of the bag or container.

摘要翻译： 包装材料由耐热基底层，密封剂层和设置在耐热基底层和密封剂层之间的至少一部分的树脂层组成。 树脂层由在室温以下的非加热温度状态下具有预定强度的树脂材料构成，在例如微波炉加热的高温状态下，强度降低。 这种包装材料可以有效地用于多种包装袋或容器，其中密封剂层设置在袋或容器的内容物侧。
