Abstract
Lined plastics sacks are made from tube sections successively severed from a tubular web consisting of a tubular inner layer of thermoplastic film around which a circular fabric of stretched plastics tapes is woven to form an outer layer. In each severed tube section, the layers are interconnected by a seam at one end to define a sack. The outer layer may be formed with side pleats defining three outwardly directed folds, the inner layer being flattened and disposed in the central such fold before the sack is filled.
