Problems solved by technology

However, there are following disadvantages in adopting this common microwave oven cooking bag: because the vent hole is added after the bag is made, so the bag body will also be punched with holes, so that the pre-packed food is easy to leak to the outside, so that when the consumer operates Trouble, food doesn't keep well either

Embodiment 1

[0021] like Figure 1-4 As shown, the microwave retort bag that can be preloaded with food and the microwave retort bag that can be preloaded with food are provided with two rows of interlocking male strips 2 and female grooves 3 at opposite positions in the bag body 1, and the male strips 2 and female grooves 3 are respectively Two pieces of film are connected to the bag body 1, at least one vent hole 4 is opened on the film between the male strip 2 and the female groove 3 on one side of the bag body 1, and a tear strip is superimposed on the bag body 1 above it 5. After the tear strip 5 is torn, the internal air vent 4 can leak out. The upper bag body 1 of the zipper is provided with a laser line 7, and the end of the laser line 7 opens a tear 6, which is torn along the laser line 7 from the tear 6, and the contents can be taken out.

[0022] The opening strength of the zipper 8 above the air vent is 80N / 50mm, and the opening strength of the zipper below the air vent is 30N...

Embodiment 2

[0025] like Figure 5 and 6 As shown in the microwave retort bag that can be preloaded with food, there are two rows of interlocking male strips 2 and female grooves 3 at opposite positions in the bag body 1, and the male strips 2 and female grooves 3 are bonded together by ultrasonic waves through two films. On the bag body 1, at least one vent hole 4 is opened on the film between the strips on one side of the bag body 1, and two laser lines are opened on the bag body 1 above it and on both sides of the vent hole 4 7. The bag body 1 in the middle part of the laser line 7 can be torn along the laser line to leak out the internal exhaust hole 4. The upper bag body 1 of the zipper is provided with a laser line 7, and the end of the laser line 7 opens a tear 6, and is torn along the laser line from the tear, so that the contents can be easily taken out. The opening strength of the zipper above the vent hole is 80N / 50mm, and the opening strength of the zipper below the vent hole...

Abstract

A microwave oven steaming / cooking bag for prepackable foodstuff. Provided at opposite positions in a bag body (1) are two rows of male strips (2) and female grooves (3) that mesh with each other. The male strips (2) and the female grooves (3) respectively are connected onto the bag body (1) via two thin films. At least one ventilation hole (4) is provided on the thin film at a side of the bag body (1) either between the male strips (2) or between the female grooves (3) or between one male strip (2) and one female groove (3). A tear-off strip (5) or a single-layer thin-film material is provided on the outer layer of the ventilation hole (4). During a material-filling process, leakage of a material from the ventilation hole (4) is prevented, also, while the bag is being moved or placed for an extended period, infiltration of impurities or airborne bacteria from the position of the ventilation hole (4) is prevented, thus extending the shelf life of the foodstuff. An extremity of the tear-off strip (5) is reinforced and heat-seal treated to allow for improved fixing onto the bag body (1). When torn open, the extremity can still be firmly kept on the bag body (1); hence, people would not readily discard the tear-off strip (5) being torn off, thus providing users with convenience while preventing environmental pollution.

Description

technical field [0001] The invention relates to the technical field of food packaging, in particular to a microwave oven cooking bag which can be prepacked with food. Background technique [0002] Plastic zippers are widely used in the packaging field because of their light weight, good flexibility, low price, and reusable characteristics. Although small and inconspicuous, it develops rapidly following the pulse of the world's packaging industry. The zipper widely used in the market is composed of two parts: a male strip and a female groove. The edge material and structure of the male strip and the female groove are basically the same. When heat sealing, the male strip and the female groove are simultaneously pressed to the opening of the bag. The two sides of the bag can be opened and closed repeatedly, keeping the freshness of the contents of the bag, safety, and extending the shelf life of the contents. However, there are following disadvantages in adopting this common ...
