Abstract
A bagging film includes two resins blended with a modifying agent. The first resin, making up about 60%-85% of the formulation, is a copolymer, polymer, elastomer, or combination thereof. The second resin, making up about 14%-39% of the formulation, is a different copolymer, polymer, elastomer, or combination thereof that is physically softer than the first resin. The modifying agent, making up about 0.25%-3.5% of the formulation, is compounded with the resin formulation such that the modifying agent creates a lubricant between the successive layers of the film.
