Stand up pouch (Stand pouch, Stand up bag), is a kind of packaging bag made of multi-layer composite materials (e.g. PET/PE, PET/AL/PE, OPP/CPP, etc.) processed through the bag-making process, which are usually designed with a right-angle or curved structure at the bottom, coupled with the reinforcement treatment on the side, making the bags able to stand up on their own without the help of external forces. This design not only facilitates the display of goods, but also improves the stability and aesthetics of the packaging. Stand-up pouch has the following features:
- Self-supporting: Standing upright on the shelf without the need of an outer box or support saves display space and enhances product visibility.
- Light weight and strength: The use of composite materials reduces the weight of the package while ensuring sufficient strength and puncture resistance to protect the products inside.
- Good sealing: Good sealing performance can effectively extend the shelf life of the product and prevent the contents from leaking or moisture.
- Easy to open and reclosure: many stand-up pouches are designed with easy tear, zip closure, etc., which is easy for consumers to use and helps to keep the products fresh at the same time.
- Printing adaptability: smooth surface, suitable for high-definition printing, which helps to enhance brand image and attract consumer attention.
- Environmental advantages: compared with traditional rigid packaging, stand-up pouches are lighter, take up less space for transport, and some of the materials can be recycled, reducing the burden on the environment.
