What is the difference between a centrefold film and a layflat tubing?

A layflat tubing is a closed tube - when cut into sections and sealed on one side, it forms a bag. A centre-folded film is the same film folded in half lengthwise - when unfolded, it provides a sheet of double the nominal width, or allows a product to be inserted from the open side. Centre-folded film offers greater size flexibility with a simple roll-unwinding process.
