Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a plastic sleeve for a packaging case which is easily folded and capable of sufficiently assuring a strength of the bent part. SOLUTION: This is a plastic sleeve for a packaging case in which a plastic sheet 20 is folded and formed into a rectangular column shape along a folding line 30. The plastic sheet 20 is a laminated sheet in which double-axis extension film 22 is laminated on a non-oriented sheet 21. The folding line 30 is formed at the non-oriented sheet 21 and it is folded in such a way that the non-oriented sheet 21 comes inside. COPYRIGHT: (C)2004,JPO |
