MULTILAYER HEAT-SHRINKABLE STYRENE-BASED FILM AND METHOD FOR PRODUCING THE SAME |
摘要 |
The present invention provides the following multilayer heat-shrinkable styrene-based film having an appropriate surface shape, together with excellent lubricity and blocking resistance, and resistance to ink skipping and like problems during the printing process: a multilayer heat-shrinkable styrene-based film having: layers (A) each containing 0.8 to 2.5 parts by weight of high impact polystyrene resin and 0.02 to 0.15 parts by weight of organic fine particles having a mean particle diameter of 0.5 to 5 mum per 100 parts by weight of a block copolymer of 75 to 90 wt % vinyl aromatic hydrocarbon and 10 to 25 wt % conjugated diene hydrocarbon; and a layer (B1) containing a block copolymer of 70 to 85 wt % vinyl aromatic hydrocarbon and 15 to 30 wt % conjugated diene hydrocarbon; or a layer (B2) containing a resin composition containing a copolymer of 98 to 40 wt % vinyl aromatic hydrocarbon and 2 to 60 wt % aliphatic unsaturated carboxylic acid ester.
