Food packaging bag oil locking structure

Abstract

The invention discloses a food packaging bag oil locking structure comprising an outer bag and an inner bag, the inner bag is located in the outer bag, the upper half portions of the inner bag and the outer bag are bonded together, a patch pocket thin air bag is arranged between the bottom of the inner bag and the outer bag, a clamping groove is formed in the inner side of the patch pocket thin air bag, the bottom of the inner bag is inserted into the clamping groove, and the inner bag and the patch pocket thin air bag are bonded. The outer bag and the outer side of the patch pocket thin air bag are bonded, the middle of the patch pocket thin air bag is outwards connected with a reset type air bag through a short air pipe, and the reset type air bag can be gradually deformed and reset to an air blowing state after being extruded. According to the food packaging bag oil locking structure, the patch pocket thin air bag is designed, by extruding the reset type air bag, air instantly flows into the patch pocket thin air bag through a one-way valve, the air bag is swelled, when the patch pocket thin air bag is swelled, the inner bag is clamped inwards, fresh-keeping oil located at the bottom is splashed upwards and makes full contact with spicy strips, therefore, the edible taste is guaranteed, the food packaging bag oil locking structure is suitable for different working conditions, and better use prospects are brought.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to an oil-locking structure of a food packaging bag. Background technique [0002] Spicy strips are a kind of food made of wheat flour or other grains and beans as the main raw material. It is a snack with a good taste and is widely welcomed by consumers. There is no unified production standard yet. Spicy strip manufacturers on the market generally implement production according to the landmarks. The implementation standards are generally DB41 / T515-2007 and GB2760. As long as they are added according to national standards, it will not affect human health; the existing spicy strip packaging bags There are roughly two forms. The first is the most traditional sealed bag. The bag contains some air, which makes the bag bulge. However, under the premise of long-term storage, the fresh-keeping oil in the bag is at the bottom for a long time due to gravity, and The spicy strips in ...

[0002] Spicy strips are a kind of food made of wheat flour or other grains and beans as the main raw material. It is a snack with a good taste and is widely welcomed by consumers. There is no unified production standard yet. Spicy strip manufacturers on the market generally implement production according to the landmarks. The implementation standards are generally DB41 / T515-2007 and GB2760. As long as they are added according to national standards, it will not affect human health; the existing spicy strip packaging bags There are roughly two forms. The first is the most traditional sealed bag. The bag contains some air, which makes the bag bulge. However, under the premise of long-term storage, the fresh-keeping oil in the bag is at the bottom for a long time due to gravity, and The spicy strips in the bag are out of joint, resulting in less oil and dryness of the spicy strips, which seriously affects the taste of food. The second method is to vacuumize the bag body, which can prolong the shelf life and lock the fresh oil in a fixed space. , to reduce the dryness of the spicy strips, but this will also lock the position of the spicy strips, compress them for a long time, make them harden, not fluffy enough, and have a greater impact on the taste. In order to prevent the occurrence of the above two situations , our factory invests funds to research the new structure of the packaging bag, and proposes a food packaging bag oil-locking structure
