摘要： A polyolefin muiltilayer laminate in which a first layer (A) made of a cycloolefin-based resin, such as an ethylene/cycloolefin random copolymer resulting from copolymerization of ethylene and a cycloolefin represented by the formula (1) given below, or a cycloolefin-based resin blend and a second layer (B) made of an olefin (co)polymer or a composition containing it are laminated. This laminate can be used as a packaging material which is superior in the interlayer adhesion, shapability, moistureproof property, transparency, flexibility, easiness of hand-cutting, heat-sealability and dead-hold property. in which n and q are 0 or 1, m is 0 or any positive integer, R - R and R and R denote each H, a halogen atom or a hydrocarbon group, wherein R - R may form, by combining with each other, a monocyclic or polycyclic ring, which may have double bond(s), and wherein R - R may have terminal-located alkylidene group.

摘要： PROBLEM TO BE SOLVED: To provide a molding excellent in mechanical properties and its production method wherein the temperature difference between the inside layer and outside layer of the multi-layer preform can be decreased without using special equipment and a large amount of energy for heating and decreasing the temperature difference, and the molding cycle of the multi-layer hollow molding can be shortened and the stress distortion of the inside and outside layers of the hollow molding is controlled. SOLUTION: A preform for a multi-lay hollow molding is a bottomed cylinder having a multi-layer structure and is molded from a thermoplastic resin composition having an inner layer containing an infrared absorbent. The multi-layer hollow molding is made by blow-molding the preform. The method of manufacture comprises the steps of heating the bottomed cylindrical multi-layer preform having the inner layer containing the infrared absorbent by an infrared heater and blow-molding the preform so as to obtain the molding.
