Beverage packaging bags refer to various bags used to package beverage products. They can be divided into the following categories according to their materials, functions and designs:

Plastic bags: Common plastic bag materials include polyethylene (PE) and polypropylene (PP). PE bags are smooth and soft, and are often used to package beverages such as juice; while PP bags are hard and slightly rough, and are suitable for beverages such as concentrated juice that require high-temperature filling. In addition, transparent plastic bags can not only show the color and layering of the beverage, but also have moisture-proof functions to ensure that the beverage remains in the best condition during transportation.

Paper bags: Paper bags are usually used for environmentally friendly and beautiful packaging needs. They can be printed in full version, and there is no version fee for ordinary printing (except for special processes). Paper bags are suitable for display and enhancing brand image.

Non-woven insulation bags: This type of bag is suitable for extreme climatic conditions and has good insulation effect. Non-woven fabrics can also be printed in full version, but a version fee is required.

‌Four-side sealed bags and three-side sealed bags‌: Four-side sealed bags have two sealed edges on each side, suitable for packaging products such as noodles and nuts; three-side sealed bags have one open side, suitable for snack foods, facial masks and other products‌.

‌Eight-side sealed bags and self-supporting bags‌: Eight-side sealed bags have four sealed edges at the bottom, suitable for packaging products such as nuts and dried fruits; self-supporting bags have a horizontal support structure at the bottom, which can stand independently, suitable for display and storage of products such as juice drinks and suckable jellies‌.

‌Zipper bags and back-sealed bags‌: Zipper bags have a zipper structure at the opening, which is extremely airtight and suitable for products such as nuts and cereals; back-sealed bags are sealed on the back of the bag body, with a continuous pattern, suitable for products such as candy and instant noodles‌.

‌Spout bags and self-supporting zipper bags‌: Spout bags have a spout design, which is convenient for direct drinking, suitable for products such as juice and beverages; self-supporting zipper bags can stand independently and are equipped with zippers, suitable for products that need to be used repeatedly‌.

These different types of beverage packaging bags are suitable for different beverage products and market demands according to their materials, functions and design features.
