Document Type and Number:
Japanese Patent JP7241012
Kind Code:
B2
Abstract:
Packaging method comprising the following steps: (a) providing a semi-crystalline thermoplastic polyester having at least one 1,4:3,6-dianhydrohexitol unit (A), at least one alicyclic diol unit (B) other than the 1,4:3,6-dianhydrohexitol units (A), and at least one terephthalic acid unit (C), wherein the molar ratio (A)/[(A)+(B)] is at least 0.05 and at most 0.30, said polyester being free of non-cyclic aliphatic diol units or comprising a molar amount of non-cyclic aliphatic diol units, relative to the totality of monomeric units in the polyester, of less than 5%, and with a reduced viscosity in solution (25° C.; phenol (50 wt. %): ortho-dichlorobenzene (50 wt. %); 5 g/L of polyester) greater than 50 mL/g; (b) preparing a heat-shrinkable film from the semi-crystalline thermoplastic polyester obtained in step (a); (c) covering a product with the heat-shrinkable film obtained in step (b); (d) applying a heat treatment to the packaged product.
