Used for granular products of varying density, Pinch Bottom Open Mouth
bags are ideal for high-end and sensitive products in the chemicals, food,
pharmaceutical, and pet food industries when barrier liners are required to
optimally preserve the bag’s contents.

These bags can be closed by sewing, but they are most often closed/sealed by Pinch Botton Closers using a pre-applied hot-melt to create sift proof closures.
