<p><P>PROBLEM TO BE SOLVED: To provide a blister pack which can be manufactured efficiently by cutting an adhesive coating process, scrapped without efforts, burnt out and thrown into a landfill without causing environmental damage, and can break away from exhaustible oil resources. <P>SOLUTION: The blister pack consists of a covering material has a recess periphery part formed at the periphery of a recess part formed for storing goods and a sheet base material for closing the recess part. The covering material and the sheet base material are both composed of a resin consisting primarily of a polylactic acid polymer, and the sheet base material is composed of a laminated body comprising at least two layers having different crystallinity. The relationship between a content ratio of D-lactic acid to the polylactic acid polymer composing the first layer of the laminated body and a content ratio of D-lactic acid to the polylactic acid polymer composing the second layer of the laminated body satisfies a specified requirement, and the second layer of the laminated body is arranged on a surface in contact with the covering material so that the recess periphery part of the covering material and the sheet base material are bonded together by thermal compression. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
