Problems solved by technology

[0002] At present, the conventional aluminum foil bags are basically 3-layer composite or 4-layer composite. After the packaging bag is sterilized or cooked at high temperature, the outer packaging of the product will melt or wrinkle, or leak, which greatly affects the performance of the product.
[0003] Ordinary high-temperature-resistant packaging bags generally have a tear opening on the lateral edge of the bag body. When the tear opening is torn by an external force, the stress distribution is uneven, not only difficult to tear, but also easy to deviate from the straight line, causing food splashes in the packaging bag
[0004] In addition, the antibacterial performance of the existing high-temperature-resistant packaging bags is not good, so that the storage time of the items inside the packaging bags is relatively short

Embodiment 1

[0027] like Figure 1 to Figure 3 As shown, a high-temperature-resistant packaging bag includes a bag body 1 and a tear opening located on the edge of the bag body 1. The bag body 1 is sequentially bonded with an adhesive to set the first aluminum foil layer 3, the first A nylon layer 4, a polyethylene film layer 5, a polyester film layer 6 and a polypropylene film layer 7, and the bag body 1 is provided with a linear laser line 2 along the direction of the tear opening. Specifically, when making the bag body, the inner surface of the first aluminum foil layer 3 is bonded to the outer surface of the first nylon layer 4 through polyurethane, and the inner surface of the first nylon layer is bonded to the outer surface of the polyethylene film layer 5 through polyurethane. The inner surface of the polyethylene film layer 5 is bonded to the outer surface of the polyester film layer 6, and the inner surface of the polyester film layer 6 is bonded to the outer surface of the polypr...

Embodiment 2

[0031] The difference between this embodiment and embodiment 1 is that, as Figure 4 As shown, the high-temperature-resistant packaging bag also includes a polyethylene terephthalate film 8 and a second nylon layer 9 bonded on the outside of the first aluminum foil layer 3 from outside to inside by an adhesive. Specifically, after bonding the film layers in the first aluminum foil layer, the outer surface of the first aluminum foil layer is bonded to the inner surface of the second nylon layer by polyurethane, and the outer surface of the second nylon layer is bonded by polyurethane Bonded to the inner surface of the polyethylene terephthalate film 8 . This kind of structural setting makes the packaging bag change from the original layer of nylon film and aluminum foil film to two layers of nylon film wrapped with aluminum foil film, so as to better protect the aluminum foil film and effectively improve the breakage of the aluminum foil when it is folded in half. Polyethylene...

Embodiment 3

[0034] The difference between this embodiment and embodiment 1 is that bamboo charcoal particles are evenly distributed in the first aluminum foil layer 3 , calculated by mass percentage, the content of aluminum foil accounts for 94%, and the content of bamboo charcoal particles accounts for 6%. The thickness of the first aluminum foil layer is 4mm. Adopting this kind of structural arrangement makes the first aluminum foil layer as the outer layer have better antibacterial performance, and increases the external antibacterial effect when the packaging bag is stored.

Abstract

The invention provides a high-temperature-resistant packaging bag. The high-temperature-resistant packaging bag comprises a bag body and a tearing opening formed in the edge of the bag body, wherein the bag body is sequentially provided with a first aluminum foil layer, a first nylon layer, a polyethylene film layer, a polyester film layer and a polypropylene film layer in an adhesive bonding modefrom outside to inside, and linear laser rays are arranged on the bag body in the direction of the tearing opening. The packaging bag is formed by compounding different packaging materials, after high-temperature sterilization, the aluminum foil bag can keep the good appearance of an outer packaging bag of a product, the tearing opening is formed in the straight line edge punctured by laser, andwhen the bag is torn in the tearing direction of the tearing opening, the packaging bag can achieve the double-face straight line and easy-to-tear effects.

Description

technical field [0001] The invention relates to the technical field of packaging bags, in particular to a high-temperature resistant packaging bag. Background technique [0002] At present, the conventional aluminum foil bags are basically 3-layer composite or 4-layer composite. After the packaging bag is sterilized or cooked at high temperature, the outer packaging of the product will melt or wrinkle, or leak, which greatly affects the performance of the product. . [0003] Ordinary high-temperature-resistant packaging bags generally have a tear opening on the lateral side of the bag body. When the tear opening is torn by an external force, the stress distribution is uneven, not only difficult to tear, but also easy to deviate from the straight line, causing food splashes in the packaging bag. [0004] In addition, the antibacterial performance of the existing high-temperature-resistant packaging bags is not good, so that the storage time of the items inside the packaging ...
