Abstract
A method for manufacturing a tableware article having a thermal-transfer printed pattern includes the following steps. Firstly, a PET resin composition including 3 to 15% by weight of an inorganic filler is provided. Next, the PET resin composition is granulated to obtain plastic granules. Then, the plastic granules are molded into the tableware article and the tableware article is post-crystallized. Finally, a thermal transfer printed pattern is printed on a surface of the post-crystallized tableware article.
Claims5
A method for manufacturing a tableware article having a thermal-transfer printed pattern, comprising:
- providing a PET resin composition including 3 to 5% by weight of an inorganic filler;
- granulating the PET resin composition to obtain plastic granules;
- molding the plastic granules into the tableware article and post-crystallizing the tableware article after the molding of the tableware article is completed, wherein in the step of post-crystallizing the tableware article, the tableware article is subjected to a heat treatment for a period of time between 10 minutes and 30 minutes at 200° C.;
- and
- forming a thermal transfer printed pattern on a surface of the post-crystallized tableware article, wherein the heat treatment temperature is higher than a temperature for forming the thermal transfer printed pattern.
