Title:
POLYETHYLENE RESIN COMPOSITION AND FILM PREPARED THEREFROM
Document Type and Number:
Japanese Patent JP3391531
Kind Code:
B2
Abstract:
PURPOSE: To obtain a resin composition improved in blocking resistance and slip properties and capable of providing films which hardly adhere to each other to have flaws by compounding a polyethylene resin with powder of a cross-linked acrylic resin or powder of a cross-linked silicone resin.
CONSTITUTION: A polyethylene resin composition contains 0.05 to 2 parts by weight powder of a cross-linked acrylic resin or powder of a cross-linked silicone resin, based on 100 parts by weight polyethylene resin. In this case, the polyethylene resin having a density of normally 0.940g/cm3 or less, preferably 0.900 to 0.935g/cm3 is used. When the density is higher than 0.940g/cm3 the low-temperature or high-speed heat sealability tends to lower when the film prepared therefrom is used with nylon or the like in the form of a composite film as a wrapping material. The cross-linked acrylic resin powder or the cross- linked silicone resin powder is the cross-linked resin powder which will not be molten ar film-forming temperatures fo polyethylene resins, e.g. 130 to 350°C.
