A stand-up pouch is a type of flexible packaging designed to stand upright on its base for display, storage, and use. While it is technically a plastic pouch, it often shares characteristics with plastic bottles.
The stand-up pouch is a relatively modern form of packaging, offering advantages such as ease of display, portability, and convenience of use. These pouches typically feature a multi-layer composite structure-such as PET/AL/PE (aluminum-plastic composite) or PET/CPP-which effectively blocks oxygen, water vapor, and UV rays, thereby extending the product's shelf life. Depending on the specific product, the structure may consist of two, three, or more layers; some stand-up pouches are also designed to withstand high-temperature sterilization (such as retort pouches) or low-temperature freezing to meet the rigorous preservation requirements of various products.
