Multiwall (or multi-wall) paper sacks or shipping sacks are often used as shipping containers for bulk materials such as fertilizer, animal feed, sand, dry chemicals, flour and cement. Many have several layers of sack papers, printed external layer and inner plies.[9] Some paper sacks have a plastic film, foil, or polyethylene coated paper layer in between as a water-repellant, insect resistant, or rodent barrier.
There are two basic designs of bags: open-mouth bags and valve bags. An open-mouth bag is a tube of paper plies with the bottom end sealed. The bag is filled through the open mouth and then closed by stitching, adhesive, or tape. Valve sacks have both ends closed and are filled through a valve. A typical example of a valve bag is the cement sack.
Paper bags are highly biodegradable and recyclable, and hence does not pose the same environmental footprint as plastic bags do. Plastic or water-resistant coatings or layers make recycling more difficult.[10] Paper bag recycling is done through the re-pulping of the paper recycling and pressing into the required shapes.
