PP valve block bottom bags are a type of valve bag that is commonly used in the packaging industry for powder products such as cement, tile adhesive, putty powder, and other dry goods.
The block bottom of the bag provides a stable base, which makes it easy to stack the bags and transport them without the risk of the bags tipping over.
Internal valve and external valve are two common designs used in valve bags. The valve spout allows for easy filling and closes automatically when the bag is filled.
Paper plastic composite bags can be printed with branding, logos, and product information, making them a great marketing tool for businesses.
Nano perforation helps remove air from the valve bag during high-speed filling. By creating very small, precise perforations in the PP material, air can be more easily forced out of the bag.
