Packaging bags

Abstract

This product is a packaging bag that can be used for cooking in a microwave oven. When using this product, for example, cooking seasonings are contained in the body of the bag. The purchaser (general consumer) opens the flap through the opening notch, opens the zipper tape and watertight seal, connecting the outside to the inside of the product (flap and body), puts food or ingredients into the product, re-closes the zipper tape to seal it, and then cooks it in a microwave oven. After cooking is complete, the bag can be opened through the opening notch in the body to remove the cooked food or ingredients. The watertight seal on the flap is intended to separate the zipper tape from the inside of the body to prevent the cooking seasonings contained in the body from coming into contact with the zipper tape before the flap is opened. The loosely fitted portion of the chuck tape acts as a steam release mechanism (steam venting mechanism) that releases steam to the outside when the internal pressure of the product increases during cooking.
