Title:
レトルト・ボイル処理用ジッパーテープおよびレトルト・ボイル処理用ジッパーテープ付包装袋
Document Type and Number:
Japanese Patent JP5457884
Kind Code:
B2
Abstract:
A head (212) of a male member (21) and a concave groove (222) of a female member (22) are engageable with and disengageable from each other and form a containing space (16) inside a bag body (10). On an inner surface of the concave groove (222), there is provided a fusion layer (24) that fuses an outer surface of the head (212) and the inner surface of the concave groove (222) facing each other, when foods are heat-sterilized for long storage. A peeling strength of the fusion layer (24) only needs to be set by selecting a material of the fusion layer (24) or setting dimensions of an area of the fusion layer (24) such that the fusion layer (24) does not require a large force for opening the bag, thereby providing a favorable opening feeling. The fusion layer (24) provides air-tightness, so that the foods can be prevented from leaking out although a pressure within the containing space (16) is increased in the heat sterilization.
