Abstract
A crop storage bag (1) made is of a high-strength textile (7) material which is extrusion-coated or laminated with a multilayer film (8) that comprises an insecticidal layer (9) in addition to a hermetic layer (10) which prevents oxygen from entering the bag. This oxygen barrier suffocates the insects inside the bag, and the insecticide kills insects that try to bore through the bag.
