What can the spout bag be used for?

The spout bag is a new type of plastic flexible packaging developed based on the self-standing bag. It is mainly divided into two parts, namely the self-standing bag and the spout. Self-reliance means standing with a film on the bottom. The nozzle is made of a new material, PE, which is blown and injected, fully meeting food-grade requirements. So let’s find out what the nozzle bag can be used for!

The packaging material is the same as ordinary composite materials, but depending on the products installed, materials with corresponding structures need to be used. The material of the aluminum foil nozzle packaging bag is aluminum foil composite film. The packaging bag is made of more than three layers of film through printing, lamination, cutting and other processes. Aluminum foil material has excellent performance, opaque, silvery and shiny, and has good barrier properties, heat sealing properties, heat insulation properties, high/low temperature resistance, oil resistance, fragrance retention, odorless, softness and other characteristics, so many manufacturers It's all on the packaging.

Straw bags are generally used to package liquids, such as juice, beverages, detergents, milk, soy milk, soy sauce, etc. There are various types of nozzles for spout bags, so there are long nozzles for jelly, juice, and beverages, nozzles for washing supplies, butterfly valves for wine, etc. The size and color can be designed according to the packaged products, and the materials are complete. There are aluminum laminated films, aluminum laminated films, plastic composite materials, nylon composite materials, etc. Depending on the material, the functions and scope of use are also different. The bag types are common stand-up bags and special-shaped bags full of personality. The display effect varies depending on the bag type.

As the advantages of flexible packaging with mouths are understood by more consumers, and as social awareness of environmental protection continues to strengthen, it will definitely become a trend to use soft packaging with mouths to replace non-resealable traditional flexible packaging with barrels. . The advantage of spout bags over general packaging forms is portability. The spout bag can be conveniently placed in backpacks and pockets, and has the feature of diversifying the company's business scope as the contents are reduced.

If you require that the spout bag can be used as a retort, the inner layer of the packaging bag needs to be made of retort material, and even a high-temperature retort of 121 can be used for eating, then PET/PA/AL/RCPP is suitable. PET is the material for printing patterns on the outer layer. The in PA to be printed is nylon, and nylon itself can withstand high temperatures; AL is aluminum foil, which has excellent barrier properties, light-shielding properties, and freshness retention properties; RPP is the inner heat-sealing film. Ordinary packaging bags can be heat sealed if they are made of CPP material. Retort packaging bags need to use RCPP or 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 paste, but the packaging must use retort aluminum foil paste.
