Bag for automatic cheese canning

Abstract

The invention discloses a bag for automatic cheese canning, which comprises a bag body with an insert edge structure; the bag body comprises a front surface, a back surface and insert edges on the left side and the right side; a certain width of bottom sealing line penetrating through the front surface, the back surface and the two insert edges is formed at the bottom of the bag body; a lower oblique angle is formed at the lower part of the bag body; the bag body consists of layered co-extrusion blown thin films with symmetrical structures of which the number of layers is seven-eleven; and each layered co-extrusion blown thin film is provided with an inner heat-sealed moisture barrier layer, an inner bonding layer, an inner oxygen barrier layer, an incense keeping core layer, an outer oxygen barrier layer, an outer bonding layer and an outer heat-sealed moisture barrier layer from inside to outside in sequence. The bag has the beneficial effects that a three-dimensional structure of the bag body is stable, the inner layer friction performance and the outer layer friction performance of the bag body are properly set, used materials are saved, and the strength is high. The bag is particularly suitable for automatic cheese canning.

Description

technical field [0001] The present invention relates to a packing bag, in particular to a bag for cheese automatic canning. The packing bag is especially suitable as a filling bag used in cheese mechanical automatic canning. The invention relates to automatic canning of moisture-proof and fragrance-preserving food, which belongs to the technical field of packaging bags. Background technique [0002] Cheese is a fermented milk product that is rich in nutritional value. Although cheese is a relatively shelf-stable food, in fact cheese is also accompanied by a fermentation process throughout the storage process, and cheese will release carbon dioxide gas during the fermentation process; although the optimal storage conditions for cheese depend on the type of cheese, However, all cheese storage containers must meet the basic conditions of being able to block moisture, block oxygen, pass through carbon dioxide, and maintain aroma; among them, blocking moisture can maintain the s...
