Problems solved by technology

Some packaging bags are composed of outer bags and inner bags. The existing films for inner bags have problems such as poor overall impact resistance, insufficient toughness, and unsatisfactory sealing and barrier properties.
There is an aluminum film layer in some film structures, but during use, the aluminum film layer is prone to creases or breaks due to external forces, which greatly affects its barrier performance, thereby reducing the overall service life
Moreover, the suspenders on the bag body are not strong enough and easy to droop, making it inconvenient to load and unload the packaging bag, which affects work efficiency

Abstract

The invention relates to a high-barrier type packaging bag with an aluminum plated film. The high-barrier type packaging bag comprises a packaging bag body, wherein a feed port is formed in the middle of the upper part of the packaging bag body, a discharge port is formed in the middle of the lower part of the packaging bag body, the packaging bag body is formed by a woven fabric outer bag and a composite type inner bag, the composite type inner bag is formed by a PET outer film layer, a first bonding layer, a first connection film layer, a second connection film layer, a second bonding layer, a PET inner film layer, the aluminum plated layer and a PE film layer, the aluminum plated layer is plated on one side of the PET inner film layer, and enhanced type slings are arranged at the four corners of the upper part of the packaging bag body. According to the high-barrier type packaging bag with the aluminum plated film, the whole impact resistance and the toughness are good, the sealing performance and the barrier property are high, the service life is long, and the sling strength is high.

Description

technical field [0001] The invention relates to a packaging bag, in particular to an aluminized film packaging bag. Background technique [0002] Compared with small woven bags, packaging bags have the characteristics of large capacity, easy loading and unloading, labor saving, and improved efficiency. Some packaging bags are composed of outer bags and inner bags. The existing films for inner bags have problems such as poor overall impact resistance, insufficient toughness, and unsatisfactory sealing and barrier properties. There is an aluminum film layer in some film structures, but during use, the aluminum film layer is prone to creases or breaks due to external forces, which greatly affects its barrier performance, thereby reducing the overall service life. Moreover, the suspenders on the bag body are not strong enough and are easy to droop, which is inconvenient for the loading and unloading of the packaging bag and affects work efficiency.
