| 备注说明 | LDF-720A is a certified prime resin specially designed for production of high drawdown thin gauged high clarity Blown films. LDF-720A features excellent combination of easy processability at high extrusion rates and very good balance of film mechanical properties. Films display very good color stability and superior heat seal performance. LDF-720A applications include films for garment laundry and dry cleaning, banana tree shroud bags, and produce bags. Maximum recommended film drawdown is 0.5 mils. LDF-720A contains no slip and no antiblock. LDF-720A complies with FDA regulation 21CFR 177.1520 (c) 2.2 and most international regulations concerning the use of Polyethylene in contact with food articles. |
