FUSION-CUT SEALED BAG MADE OF POLYLACTIC ACID BASED RESIN |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To stably provide a fusion-cut sealed bag with biodegradability and sufficient strength at a fusion-cut seal. <P>SOLUTION: The fusion-cut sealed bag made of a polylactic acid based resin comprises a fusion-cut sealed polylactic acid based resin film. When an average thickness of the resin film is tμm, a longitudinal sectional area of the fusion-cut seal is in a range of 6,000 to (110×t<SP>2</SP>)μm<SP>2</SP>. In this case, the polylactic acid based resin film is preferably an oriented film stretched in at least one direction. <P>COPYRIGHT: (C)2004,JPO</p> |
