FIELD: chemistry.
SUBSTANCE: invention relates to multilayer flexible polymeric films for food packaging and relates to a composition and method for manufacturing a flexible packaging film. Method includes using a blown film comprising high density polyethylene (HDPE), at least 50% by weight of an inorganic filler having an initial thickness, and orienting the blowing film in the processing direction to obtain an oriented film having a final thickness of at least 35% less than the initial thickness.
EFFECT: invention provides a flexible HDPE packaging film that provides high yield, tensile strength, and a reduction in gauge variation to improve print quality.
