NOVELTY - This utility new type claims a one controlled release composite packaging film, comprise sequentially formed composite of 10-16 microns thickness of PET layer, soft aluminium foil layer and 30-70 microns thickness of EVA layer, a PET layer and soft aluminium foil layer of 6-9 microns thick set with 50-100 nm thick of between graphene-reinforced layer, a PET layer and graphene-reinforced layer or graphene-reinforced layer of at least part area set with gel polysaccharide or sodium alginate, between other adjacent layer set with solvent-free polyurethane adhesive. This utility new type of machinery has excellent property of excellent tensile strength, tear resistance, impact resistance and abrasion resistance property, satisfy technology standard of damp-proof, oxygen barrier, the inner one section time and so on, easy moulding, easy mass production, beyond the inner use time, high molecular material can be of a short time of inner degradation, the environmental pollution is reduced.
