ISO 11897Packaging - Sacks made from thermoplastic flexible film - Tear propagation on edge folds
ISO 11897 specifies a method for the determination, under given conditions, of the resistance to tear propagation on an edge fold of sacks made from thermoplastic flexible film. Measurements on folded and unfolded film permit the determination of the residual resistance in the fold.
Before conducting ISO 11897, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
