Packaging and wrapping film

摘要: Biaxially oriented, heat-shrinkable film-making process and film with improved toughness extrusion processibility are disclosed. The comprises at least one layer of substantially linear ethylene homopolymer or interpolymer, wherein the polymer has an uniform branching distribution, is also characterized as having essentially no fraction, a single DSC melting peak, density greater than about 0.85 g/cc, simple bubble 1% secant modulus below 195,000 kPa. biaxially oriented shrinkage value from 18% to 85% 135° C. useful in preparing heat-shrink bags for packaging food articles like poultry fresh red meat.
