When is a paper cross-bottom sack sufficient, and when is a plastic combination required?

A pure cross-bottom sack (paper) is ideal for non-sensitive goods that need to breathe, as is the case with certain construction materials or animal feed. However, as soon as your product is hygroscopic, requires aroma protection, or strict hygiene requirements must be met, we integrate plastic films. These serve as an effective moisture, grease, or gas barrier.
