Features
Repeated opening and closing, convenient and hygienic
Four-sided sealed zipper bags add a zipper design on the basis of four-sided sealed bags. This innovation allows the bag to be opened and closed repeatedly, greatly improving the convenience of use. Zippers are usually made of PE, CPP or multi-layer composite zipper materials, which are not only durable but also easy to operate, ensuring that users can easily open and close each time, reducing direct contact between hands and items in the bag, thereby improving hygiene standards. This feature is particularly critical for products that need to be frequently accessed, such as snacks, pet food, etc.
