New terpolymers bond multilayer packaging.Two new maleated terpolymers bond to "difficult" substrates in multilayer packaging. Lotader 4403 and 4503 from Arkema in Philadelphia are designed for extrusion lamination lamination a laminar structure or arrangement. and coating. These low-odor resins are said to bond oriented PP, PET, and nylons, as well as PE, metallized and printed plastics, cellophane cellophane, thin, transparent sheet or tube of regenerated cellulose. Cellophane is used in packaging and as a membrane for dialysis. It is sometimes dyed and can be moisture-proofed by a thin coating of pyroxylin. , aluminum foils, paper, and fiberboard fi·ber·board n. A building material composed of wood chips or plant fibers bonded together and compressed into rigid sheets. Noun 1. . They permit coextrusion coating onto EVOH EVOH Ethylene Vinyl Alcohol Polymer (chemical industry) , nylon, and polyester. These ready-to-use resins require no dilution, primers, or drying. Lotader 4403 (9 MI) and 4503 (8 MI) have melting points of 171 F to 172 F, Vicat point of 117 F, ultimate elongation of 750%, and ultimate tensile strength of 1320 to 1392 psi.
