Abstract

This product is a packaging bag for sealing contents such as food, and when the internal pressure increases due to heating in a microwave oven or the like, a portion of the triangular welded part protruding inward peels off, creating a break that connects to the inside, allowing internal steam to be released, thus enabling safe heating in a microwave oven or the like.
