<p>PURPOSE:To provide polybutene-based resin laminate suitable for stretch-film for food packing due to its excellence in transparency, stretchability, flexibility, slipperiness, heat fusion characteristics and self-adhesion, its good maintenance of transferency after stretching, its no-development of wrinkle and the like and its favorable holding of shrinking force. CONSTITUTION:The polybutene-based resin laminate concerned consists of intermediate layer (a) mainly made of 1-butene-propylene copolymer A, the propylene content in which is 15-40mol% and the melt flow rate of which is 0.1-30g/10min, and upper front layer b1 and lower front layer b2 mainly made of polyolefin-based resin B and laminated onto both the sides of said intermediate layer (a).</p> |
