摘要： A process for granulating a polyamide resin involving: (a) providing an underwater granulating device having a heated multiple-bore die wherein the bores have an internal diameter ranging from 1.2 to 2.5 mm and a length of from 12 to 50 mm; (b) providing a polyamide resin melt having a viscosity, at 160° C., of less than 3,000 mPas; (c) cooling the polyamide resin melt to form a cooled polyamide resin; (d) introducing the cooled polyamide resin into and through the heated multiple-bore die to form an extrudate; (e) providing a source of water; (f) contacting the extrudate with the water to form a cooled extrudate; and (g) cutting the cooled extrudate into granules.

摘要： The use of multilayer heat shrinkable film for advantageous high shrinkage but low shrinkage force is combined with the use of recycle scrap of such film to provide multilayer heat shrinkable film retaining these advantageous properties. Exemplary of the film is a core of a blend of certain linear low density polyethylene with certain highly branched low density polyethylene sandwiched between two relatively thin outer layers of propylene/ethylene copolymer, with the core also containing recycle scrap of the multilayer film.
