Brief introduction of nozzle stand-up pouch
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 a new material PE blow molding , It is made by injection molding and fully meets food-grade requirements.
The material of the nozzle stand-up pouch
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. 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 ranges of use. The bag type is Common stand-up bags and special-shaped bags full of individual characteristics, different bag types have different display effects. The material of the aluminum foil nozzle packaging bag is made into packaging bags through various processes such as printing, laminating, and cutting with three or more films
Purpose of nozzle bag
Spout bags are generally used to pack liquids, such as fruit juice, beverages, detergents, milk, soy milk, soy sauce, etc.
The style of the nozzle
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. 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.
Advantages of nozzle stand-up pouch
The biggest advantage of spout bags over common packaging forms is portability. The spout bag can be conveniently placed in a backpack or even a pocket, and the business scope of the factory can be diversified as the content decreases.
Special requirements for nozzle cooking bags
If the nozzle bag can be steamed, then the inner layer of the packaging bag needs to use steaming material. If it can reach 121 degrees Celsius, it can be used and eaten. Then PET/PA/AL/RCPP is the best choice, and PET is the outermost. The layer is used to print the pattern material, and 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, and 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 material. Retort packaging bags need to use RCPP, which 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.
