PACKAGING BAG FOR MICROWAVE HEATING

摘要

PROBLEM TO BE SOLVED: To enable cooking of food in a packaging bag by releasing steam appropriately.

SOLUTION: In the packaging bag for microwave heating, a steam port 6 communicating with the inside of the bag is formed at the heat seal part of the bag 1 to be made by being sealed off by heat-sealing. When heated by a microwave, the heat seal part including the steam port 6 is cut to open the bag, allowing the inner pressure and an excessive steam to leak from the steam port 6 to outside.
