Stand-up pouches have many advantages in improving product grades, enhancing shelf visual effects, portability, ease of use, preservation and sealability. The fully degradable compostable stand-up pouch is laminated by the kraft paper degradable film structure. It can have 2 layers or 3 layers of material, depending on the different products of the package, and an oxygen barrier protective layer can be added as needed, such as high-density degradable film, VMPBAT film etc., reduce the oxygen transmission rate and prolong the shelf life of the product.
So far, compostable stand-up bags are basically divided into the following three types:
1. Ordinary stand-up bag without zipper:
The general form of stand-up pouch has no zipper, adopts the form of four sealing edges, and cannot be re-closed and repeatedly opened. This kind of stand-up pouch is generally used in the industrial supplies industry.
2. Stand up pouch with zipper:
Self-supporting pouches with zippers can be re-closed and re-opened. Since the zipper form is not closed and the sealing strength is limited, this form is not suitable for encapsulating liquids and volatile substances. According to the different edge sealing methods, it is divided into four edge sealing and three edge sealing. Four edge sealing means that the product packaging has a layer of ordinary edge sealing in addition to the zipper seal when it leaves the factory. The zipper is then used to achieve repeated sealing and opening, which solves the disadvantage that the zipper edge sealing strength is small and is not conducive to transportation. The three-sealed edge is directly sealed with a zipper edge, which is generally used to hold lightweight products. Self-supporting pouches with zippers are generally used to package some light solids, such as coffee beans, biscuits, tea leaves, vanilla, etc., but four-sealed self-supporting pouches can also be used to package heavier products such as rice and cat litter. At the same time, the degradable materials are environmentally friendly and will not cause plastic pollution to the environment.
3. Special-shaped stand-up bag:
That is, according to the needs of packaging, new stand-up bags of various shapes produced by changing on the basis of traditional bag types, such as waist design, bottom deformation design, handle design, etc. It is the main direction of the value-added development of stand-up pouches at present.
With the progress of society, the improvement of people's aesthetic level and the intensification of competition in various industries, the design and printing of stand-up bags have become more and more colorful, and their forms are more and more. The development of special-shaped stand-up bags has gradually replaced the status of traditional stand-up bags. the trend of.
