Application of suction nozzle bags

2022-02-22


  The self-supporting spout pouch packaging is mainly used in products such as juice drinks, sports drinks, bottled drinking water, squeezable jelly, and condiments. In addition to the food industry, the application of some cleaning products, daily cosmetics, and medical supplies is also gradually increasing.
  The self-supporting spout pouch is more convenient for pouring or sucking out the contents, and it can be resealed and reopened, which can be considered a combination of a self-supporting pouch and a regular bottle mouth. This type of self-supporting pouch is generally used in daily product packaging, for holding beverages, shower gel, shampoo, ketchup, cooking oil, jelly, and other liquid, colloidal, and semi-solid products.
  The self-supporting spout pouch is a relatively novel packaging form, with advantages over common packaging forms in terms of portability; the self-supporting spout pouch can be easily placed in a backpack or even a pocket, and its volume can be reduced as the contents decrease, making it more convenient to carry. It has advantages in enhancing product quality, strengthening shelf visual effects, being lightweight, convenient to use, preserving freshness, and being sealable. The self-supporting spout pouch is made of a laminated structure of PET/foil/PET/PE, and it can also have 2 layers, 3 layers, and other specifications depending on the different products being packaged. An oxygen barrier layer can be added as needed to reduce oxygen permeability and extend the product's shelf life.
  Currently, the packaging of soft drinks in the market mainly consists of PET bottles, composite aluminum foil bags, and cans. As homogenization competition becomes increasingly evident, improvements in packaging are undoubtedly one of the powerful means of differentiated competition. The self-supporting spout pouch combines the resealability of PET bottles with the fashion of composite aluminum foil bags, and it also has printing advantages that traditional beverage packaging cannot match. Due to the basic form of the self-supporting pouch, the display area of the spout pouch is significantly larger than that of PET bottles and superior to non-standing packaging like stand-up pouches. Of course, since spout pouches belong to the category of flexible packaging, they are currently not suitable for carbonated beverage packaging, but they have unique advantages in juice, dairy products, health drinks, and jelly foods.
