A high-strength cold-shrink stretch sleeve film is a three-layer structure which comprises an outer layer, a middle layer and an inner layer respectively. The outer layer comprises metallocene linear low-density polyethylene (MLLDPE), ethylene-vinyl acetate copolymer or ethylene-propylene copolymer (an elastomer) or multiple copolymers of propenyl and functional masterbatch; the middle layer comprises the metallocene linear low-density polyethylene (MLLDPE), the ethylene-vinyl acetate copolymer (EVA) or the ethylene-propylene copolymer (the elastomer) or the multiple copolymers of propenyl; and the inner layer comprises the metallocene linear low-density polyethylene (MLLDPE) and the functional masterbatch. The high-strength cold-shrink stretch sleeve film has the advantages of high clamping force, strong recurrent force, good anti-pricking performance and low production cost.
