Multilayered body for medical containers and medical container

摘要

The present invention provides a multilayered body for medical containers, in which the innermost layer formed from a cyclic polyolefin exhibits favorable adhesion to another layer without using an adhesive, which exhibits excellent heat resistance, and which provides favorable blocking resistance when formed as a film, as well as a medical container formed from this multilayered body for medical containers, which suffers minimal deterioration in properties such as transparency and peel strength even when subjected to sterilization with high-pressure steam or the like.

主权项

1. A multilayered body for medical containers used in forming a medical container, comprising at least
an innermost layer composed of a cyclic polyolefin, an intermediate layer which is formed adjacently to said innermost layer and comprises, as a main component, a linear low-density polyethylene produced using a single-site catalyst, and an outermost layer containing a high-density polyethylene, wherein said cyclic polyolefin is a hydrogenated product of a ring-opening polymer of a cyclic olefin monomer and the body has a total thickness within a range from 60 to 1,000 μm, and is composed of three layers consisting of said innermost layer having a thickness of 5 to 100 μm, said intermediate layer, and said outermost layer having a thickness of 5 to 100 μm.
