A stand-up pouch is a flexible packaging bag with a horizontal support structure at the bottom. Its key feature is its ability to stand upright without any support, maintaining stability whether opened or unopened. Below is a detailed introduction to stand-up pouches:

Materials and Structure

Stand-up pouches are usually made from multi-layer composite materials, such as PET/aluminum foil/PET/PE composite structures, but may also have 2-layer, 3-layer, or other material specifications. The choice of materials depends on the characteristics and requirements of the product being packaged.

As needed, stand-up pouches can incorporate an oxygen barrier layer to reduce oxygen permeability and extend product shelf life.

Types and Characteristics

Stand-up pouches are mainly divided into the following types:

Ordinary stand-up pouch: Uses a four-side seal, cannot be resealed or reopened, generally used in the industrial goods industry.

Stand-up pouch with spout: More convenient for pouring or dispensing contents, can be resealed and reopened, suitable for daily necessities packaging, such as beverages, shower gel, shampoo, etc.

Stand-up pouch with zipper: Can also be resealed and reopened, but the sealing strength is limited, not suitable for sealing liquids and volatile substances. According to the sealing method, it is divided into two types: four-side seal and three-side seal.

Spout stand-up pouch: Combines the convenience of a stand-up pouch and a spout, as well as the low cost of an ordinary stand-up pouch, but cannot be resealed, suitable for single-use liquids, colloids, and semi-solid products.

In addition, there are also uniquely shaped stand-up pouches, such as those with a waisted design, deformed bottom design, handle design, etc. These new types of stand-up pouches are a key focus for the value-added development of stand-up pouches.
