Abstract

The invention discloses a candy packaging bag and a preparation method thereof. The candy packaging bag is prepared by weighting the following components in parts by weight: LDPE (Low-Density Polyethylene), DOP (Dioctyl-Phthalate), PP (Propene Polymer), 4,5-epoxytetrahydroisooctyl phthalate, PS (Poly Styrene), zinc stearate, a thickening agent, calcium stearate, tricresyl phosphate, silicon oxide, a toughening agent, CPE (Chlorinated Polyethylene), triphenyl phosphite, MBS (Methyl Methacrylate) and epoxy soybean oil octyl ester, evenly mixing, extruding, granulating and then drawing, winding, inspecting and warehousing. The light transmittance of the product is 95-98%, the longitudinal tensile strength is 45-55MPa, the transverse tensile strength is 20-30MPa, the longitudinal elongation at break is 450-550%, the transverse elongation at break is 850-950%, the longitudinal tear strength is 120-130N / mm and the transverse tear strength is 140-150N / mm.

Description

technical field [0001] The application belongs to the field of packaging bag preparation technology, and in particular relates to a candy packaging bag and a preparation method thereof. Background technique [0002] Packaging bags refer to bags used to pack various supplies, making the goods convenient to transport and store during the production and distribution process. Widely used in daily life and industrial production. The development of packaging bags has gone through four distinct stages: the original packaging bag stage, the large packaging bag stage, the small packaging bag stage, and now gradually entering a new stage of environmentally friendly (green) packaging bags. With the development of the commodity economy, the commodity nature of the packaging itself is becoming more and more obvious. It has become a special product that is no longer attached to commodity production, and a widely used product that all commodities cannot do without. With the rapid develop...
