Abstract

PROBLEM TO BE SOLVED: To solve a problem that in a conventional automatic holing bag for use in a microwave oven, an air hole formed beforehand is sealed with a tape, which is peeled off when the bag is heated in a microwave oven, or an easy- open-film is used to change the shape of seal or a weak seal is provided; however, these methods require much time and erroneously used by a user, and the easy-open-film is weak at its sealed portion and tends to break. SOLUTION: In the automatic hole-opening bag wherein a sealant material having perforation like holes is pasted to a portion where a non-adhesive layer is provided in a laminated plastic film, the pressure of water vapor generated in the bag is applied to the inside of the bag, and the water vapor passing through the perforation flows through the non-adhesive layer so as to be discharged from the sealed part. Thus, even if the sealed bag is put into a microwave oven and heated and water vapor is generated in the bag, the bag is not ruptured.

Means for Solving the Problems In order to achieve the above object, the present invention is as follows. That is,
The invention according to claim 1 is a manufacturing bag in which a non-adhesive layer is partially provided in a plastic laminated film, and a sealant material having perforated vent holes is bonded to that portion. Since the ink may adhere to the contents from the vent holes of the sewing machine, a three-layer structure is used to prevent this, and the pressure of the steam generated in the bag is applied from the inside of the bag due to the above film structure and form. By configuring so that the vapor that has passed through the eye-shaped ventilation holes passes through the non-adhesive part, penetrates the seal part and deaerates,
When the bag is placed in an unopened microwave oven and heated, the bag is prevented from breaking even if a vapor pressure is generated in the bag.
