The nozzle bag is a new type of plastic flexible packaging developed on the basis of the stand-up 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 to support standing, and the suction nozzle is made of new material PE blow molding. , injection molding, fully meet the food-grade requirements.
This kind of packaging material is the same as the ordinary composite material, but it needs to use the material with the corresponding structure according to the different products to be installed. The aluminum foil nozzle packaging bag is made of aluminum foil composite film. After three or more layers of film are printed, compounded, cut and other processes to make the packaging bag, because the aluminum foil material has excellent performance, it is opaque, silver-white, and reflective. , Good barrier properties, heat sealing properties, optical shading properties, high/low temperature resistance, oil resistance, fragrance retention, no peculiar smell, softness and other characteristics, are deeply loved by consumers, so most manufacturers use aluminum foil on packaging, Not only practical but also very classy.
Spout bags are generally used to package liquids, such as juices, beverages, detergents, milk, soy milk, soy sauce, etc. Due to the various types of nozzles in the nozzle bag, there are long nozzles for jelly, juice and beverages, nozzles for washing products, and butterfly valves for red wine.
The size and color 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 scope 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.
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 to replace barrels, and use spouted flexible packaging to replace traditional flexible packaging that cannot be resealed. The biggest advantage of spout bags over common packaging forms is portability. The mouthpiece bag can be easily put into a backpack or even a pocket, and can be reduced with the content. The business scope of our factory has the characteristics of diversification.
If the nozzle bag is required to be retortable, then the inner layer of the packaging bag needs to be made of retort material. If 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 is used to print the pattern, and the printing ink should also use the ink that can be cooked; PA is nylon, and nylon itself can withstand high temperature; AL is aluminum foil, and the insulation, light-proof and fresh-keeping properties of aluminum foil are excellent; RCPP is the innermost heat-sealing film. Ordinary packaging bags can be heat-sealed by using CPP material. Retort packaging bags need to use RCPP, which is retort CPP. The films of each layer also need to be compounded to make the packaging bag. Of course, ordinary aluminum foil packaging bags can use ordinary aluminum foil glue, and cooking bags need to use cooking aluminum foil glue. Step by step, you can create a perfect packaging.
