Abstract
Tubular plastics film (18) is bunched up. Air is blown through one end of the tube by a fan (64). The air passes through the tube and through a spreader (30) of the film and then past a sealing station. The sealing station effects two adjacent seals across the film and also creates a line of weakness between those adjacent seals in a single operation. Air bags are formed between spaced seals effected in sequential sealing operations.
