    摘要： An object of the invention is to provide compositions which have low-temperature heat sealing properties, are free from stickiness, may achieve a heat seal strength controlled within a certain definite range when heat sealing takes place at low temperatures, have small changes in heat seal strength with time, and are such that in the packaging applications, the strength required to open the packages may be easily controlled within a certain definite range, and high-performance packages may be designed. The invention resides in a 1-butene.α-olefin copolymer composition including 99 to 1 parts by mass of at least one olefin polymer (X) selected from propylene polymers (X-1) and ethylene polymers (X-2), and 1 to 99 parts by mass of a 1-butene.α-olefin copolymer (Y) containing 0.1 to 30 mol % of one or more α-olefins selected from α-olefins and having a molecular weight distribution (Mw/Mn) of 1.0 to 3.5 [wherein the total of (X) and (Y) in the composition is 100 parts by mass].

    摘要翻译： 本发明的目的是提供具有低温热封性能，无粘性的组合物，当在低温下进行热封时，可实现在一定范围内控制的热封强度，热密封变化小 随着时间的推移，并且在包装应用中，打开包装所需的强度可以容易地控制在一定范围内，并且可以设计高性能包装。 本发明涉及含有99〜1质量份的选自丙烯聚合物（X-1）和乙烯聚合物（X-2）中的至少一种烯烃聚合物（X）和1-乙烯聚合物（X-2）的1-丁烯-α-烯烃共聚物组合物， 至99质量份含有0.1至30mol％的选自α-烯烃中的一种或多种α-烯烃并且分子量分布（Mw / Mn）为1.0至1.0的1-丁烯-α-烯烃共聚物（Y） 3.5 [组合物中（X）和（Y）的总和为100质量份]。
