The die-cut liners on pinch-bottom paper bags are designed to package coffee or nuts for specific purposes.
During the assembling process of the bag, the die-cut liner is placed inside the pocket and serves as a further barrier between the contents and external factors such as air and moisture.
It is ideal for products with a long shelf life or needing to stay fresh for a longer period.
In addition to being secure, the pinch bottom closure is lined with a die-cut liner for added protection.
