What can the spout bag be used for? Can the special-shaped nozzle bag be steamed

The nozzle bag is a new type of plastic flexible packaging developed on the basis of the self-supporting bag. It is mainly divided into two parts, self-supporting and suction nozzle. Self-supporting means that there is a layer of film at the bottom that can support standing, and the suction nozzle is made of a new material PE blow molding , It is made by injection molding and fully meets food-grade requirements.

This kind of packaging material is the same as the ordinary composite material, but the material of the corresponding structure needs to be used according to the different products installed. The aluminum foil nozzle packaging bag is made of aluminum foil composite film, which is made into a packaging bag through three or more layers of film for printing, laminating, cutting and other processes. Because the aluminum foil material has excellent performance, it is opaque, silvery white, and has anti-gloss , Good barrier properties, heat sealability, light shading, high/low temperature resistance, oil resistance, fragrance retention, no peculiar smell, softness, etc., which are deeply loved by consumers, so most manufacturers use aluminum foil on the packaging. Not only practical but also very high-end.

Spout bags are generally used to pack liquids, such as fruit juice, beverages, detergents, milk, soy milk, soy sauce, etc. Due to the various forms of nozzles in the nozzle bag, there are long nozzles for sucking jelly, juice, and beverages, nozzles for detergents, and butterfly valves for red wine.

Specifications, sizes and colors can be designed according to the product to be packaged. The materials are complete, including aluminum foil composite film, aluminized composite film, plastic composite film, nylon composite film, etc. Different materials have different functions and scopes of use. The bag type is Common self-supporting bags and special-shaped bags full of individual characteristics, different bag types have different display effects.

As the advantages of spouted flexible packaging are understood by more consumers, and with the continuous strengthening of social environmental protection awareness, it will become a trend to use spouted flexible packaging instead of barrels, and use spouted flexible packaging to replace non-reclosable traditional soft packaging. The biggest advantage of spout bags over common packaging forms is portability. The spout bag can be conveniently put into a backpack or even a pocket, and the business scope of the factory can be diversified as the content decreases.

If the nozzle bag can be steamed, then the inner layer of the packaging bag needs to use steaming material, and it can be used and eaten at a high temperature of 121 degrees Celsius, then PET/PA/AL/RCPP is the best choice, and PET is the outermost. The material of the layer used to print the pattern, the printing ink should also use the ink that can be steamed; PA is nylon, nylon itself can withstand high temperature; AL is aluminum foil, aluminum foil has excellent insulation, light resistance, and freshness; RCPP is the innermost heat-sealing film. Ordinary packaging bags can be heat-sealed using CPP materials. Retort packaging bags need to use RCPP, that is, retort CPP. Each layer of film also needs to be compounded to make a packaging bag. Of course, ordinary aluminum foil packaging bags can use ordinary aluminum foil glue, while cooking bags need to use cooking aluminum foil glue, step by step and one detail to create a perfect package.
