Paper Sack

Based on customer request can  have several layers of sack papers, printed external layer and inner plies and a  plastic film, foil, or polyethylene coated paper layer in between as a water-repellant, insect resistant, or rodent barrier. Paper sacks are made of Kraft paper having the advantage of being soft and strong at the same time. The stretch or elongation increases the energy required to break the material. They carry and protect products up to 50 kg, and adapt easily to the nature of their contents and to handling constraints. Depending on the product, the weight ratio of a paper sack to its contents can be up to 1:250. The strength is due to the arrangement of the fresh fibers used in Kraft paper production.

Thanks to different paper sack constructions with glue, barrier, layer or surface concepts, paper sacks can also be moisture resistant. There are many different types of paper sacks available for the various end uses. The most common sack types are valve sacks, pinch bottom sacks, SOS (self opening sacks) sacks and (pasted) open mouth sacks.
