Product analysis
spout pouch is a relatively new packaging form, compared with the common packaging form, the biggest advantage is portability; The spout pouch can be easily put into a backpack or even a pocket, and can be reduced with the reduction of the contents, more convenient to carry. It has advantages in many aspects such as improving product grade, strengthening the visual effect of shelves, portability, convenience of use, freshness preservation and sealability. spout pouch is laminated by polyester/aluminum foil/PET/PE structure, can also have 2 layers,3 layers and other specifications materials, according to the different products of packaging, can increase the oxygen insulation protective layer according to need, reduce the oxygen penetration rate, extend the shelf life of the product.
Soft drink packaging on the market, PET bottles, composite aluminum paper bags, cans as the main form, in the homogenization of competition is increasingly obvious today, the improvement of packaging is undoubtedly one of the powerful means of differentiated competition. The self-supporting mouthpiece bag combines the repeated packaging of PET bottles and the fashion of composite aluminum paper bags, and also has an incomparable advantage in the printing performance of traditional beverage packaging. Because of the basic shape of the spout pouch, the display area of the mouthpiece bag is significantly larger than that of PET bottles, and it is better than the packaging of the non-standing Benefi bag. Of course, because the suction bag belongs to the category of flexible packaging, it is not suitable for the packaging of carbonated beverages, but it has unique advantages in juice, dairy products, health drinks, jelly foods and other aspects of independent suction bag packaging is mainly used in juice drinks, sports drinks, bottled drinking water, absorbable jelly, condiments and other products, in addition to the food industry, The application of some washing products, daily cosmetics, medical supplies and other products is also gradually increasing.
The spout pouch is more convenient to dump or absorb the contents, and can be re-closed and re-opened, which can be considered as a combination of self-supporting bag and ordinary bottle mouth. This kind of self-supporting bag is generally used in daily necessities packaging, for containing beverages, shower gel, shampoo, ketchup, cooking oil, jelly and other liquid, colloidal, semi-solid products. The suction mouth bag has the characteristics of easy dumping and absorbing internal items, can be repeatedly opened and closed, in the field of liquid and semi-solid, more sanitary than zipper bags, more cost-effective than bottles, so it has developed rapidly and become a popular bag type in the market, often used in the packaging of beverages, detergents, milk, hot sauce, jelly and other products; The common suction nozzle bag on the market is generally composed of three or more layers of film, including the outer layer, the middle layer and the inner layer
The outer layer is printed material. At present, the commonly used vertical packaging printing materials on the market are cut from ordinary OPP, and there are high strength and high barrier materials such as PET and PA, which can be selected according to the situation. Common materials such as BOPP and dull BOPP can be used to package dried fruit solid products. If liquid products are packaged, PET or PA materials are generally used.
The intermediate layer generally uses high-strength, high-barrier materials, such as PET, PA, VMPET, aluminum foil, etc., and RFID requires the surface tension of the sandwich material to meet the composite requirements, and must have a good affinity with the adhesive.
The inner layer is the heat sealing layer, which is generally made of materials with low temperature heat sealing properties such as PE, CPE and CPP. The surface tension of the composite surface should meet the composite requirements, and it should have good anti-pollution ability, anti-static ability and heat sealing ability.
It has advantages in many aspects such as improving product grade, strengthening the visual effect of shelves, portability, convenience of use, freshness preservation and sealability. Self-standing nozzle bag is laminated by polyester/aluminum foil/PET/PE structure, can also have 2 layers,3 layers and other specifications materials, according to the different products of packaging, can increase the oxygen insulation protective layer according to need, reduce the oxygen penetration rate, extend the shelf life of the product.
