Packaging bags

Abstract

This product is a packaging bag that can be used for cooking in a microwave oven. When this product is used, for example, it is sold with cooking seasonings stored in the body. Then, a purchaser (general consumer) opens the flap along the opening line to form an opening, opens the zipper tape part and the watertight joint to connect the outside with the inside of this product (flap part, inside of the body), puts ingredients and other ingredients into this product, refits the zipper tape part to seal, and can cook in a microwave oven. After cooking is completed, the body can be opened along the opening line to take out cooked ingredients and other ingredients. The watertight joint of the flap is for separating the zipper tape part from the inside of the body to prevent the cooking seasonings and other ingredients stored in the body from coming into contact with the zipper tape part before the flap part is opened. The weak fitting portion of the zipper tape portion is released by an increase in the internal pressure of the article during cooking, and acts as a mechanism for releasing steam to the outside (steam release mechanism).
