The roll material is formed as a single piece, making it suitable for high-speed bag-making and filling operations on fully automatic packaging machines. It features excellent flexibility and is resistant to tearing. Custom printing and thickness adjustments are available. Resistant to high and low temperatures as well as acids and alkalis, these products are widely used for the sealed packaging of food, chemical powders, desiccants, and electronic consumables.
