Abstract
The present invention describes easy-to-tear polymeric flexible packaging substrate i.e. polymeric film/laminate. The easy-to-tear flexible packaging film is obtained by providing a plurality of non-through micro-indentations on one or both surface of the film. The micro-indentations are located over the entire or partial surface area of the film. The easy-to-tear packaging laminate of the present invention is obtained by providing a plurality of non-through micro-indentations on at least one surface of at least one layer of the packaging laminate. The micro-indentations are located over the entire or partial surface area of the corresponding surfaces of the layers of the laminate. The micro-indentations may have a depth between 1˜70% of the thickness of the polymeric layer. The density of the micro-indentations on a particular surface may be from 10/cmto 10,000/cm.
