The laminating object which has the adhesion layer which consists of a copolymer of a 4-methyl-1-pentene and 1-hexene on the outside of substrate. As composition of this copolymer, they are 50 - 80 % of the weight of 4-methyl-1-pentene contents, and 20 - 50 % of the weight of 1-hexene contents.Since this copolymer has self-adhesiveness, it can be used suitable for the use for which self-adhesiveness is needed by using for the outer layer at the time of considering as a laminating object. Moreover, since this copolymer has pliability, it does not have the necessity of blending plasticizer or softening agent so much, and it can prevent the problem or trouble of bleeding out of them.That is, by using this copolymer as an outer layer of a laminating object, this copolymer becomes possible acquiring a laminating object with very few bleeding out substances from a laminating object to a packed thing while giving pliability and adhesiveness, with the heat resistance, transparency, and safe health nature held which was excellent in 4-methyl-1-pentene system resin. As a concrete use, the use of the lap film with which high-frequency heating is presented, and the products of which heat resistance and pliability are required, for example, the container or a lid for microwave ovens, the container for retort pouch for packed foods and a transfusion bag, a squeeze tube, etc. can be mentioned.
