Description of PE Films in rolls for sachet bags

PE membrane is larger permeability, and with the increase of its density, the permeability is decreased. PE film has moisture-proof, small moisture permeability.

Low density polyethylene

Its density is about 0.*2g/cm3. Low density polyethylene film transparency and good sealing performance, can waterproof, moisture-proof; low tensile strength, tensile elongation, prone to wrinkles, thin film 0.*3mm, tension control should be small, and everywhere to constant tension, especially easy to deformation when heated, lead to registration difficulties. So when dry film, surface temperature not too high (within **0C). According to the film forming process, can be divided into blown film (IPE), cast film (CPE), several low foaming film etc.. IPE thin film tensile strength and opening than CPE thin film, the positive print, can be used as a food bag, garment bag etc.;
