Abstract

The invention relates to a high heat absorption high-brightness bottle-grade polyester chip which is characterized by containing titanium nitride and barium sulfate, wherein the weight content of titanium nitride in the polyester chip is 3-30ppm; the weight content of barium sulfate in the polyester chip is 0.1-5ppm. The invention further relates to a preparation method of the high heat absorption high-brightness bottle-grade polyester chip. The bottle-grade polyester chip provided by the invention has the advantages of high heat absorption and high brightness.

Description

technical field [0001] The present invention relates to a bottle-grade polyester chip, in particular to a bottle-grade polyester chip with high heat absorption and brightness and a preparation method thereof. Background technique [0002] Polyester is a general term for thermoplastic linear saturated polyester represented by polyethylene terephthalate (PET). One of its important uses is in the field of food packaging. As a food packaging material, PET can be made into biaxially stretched packaging film, and can also be made into amorphous preforms and then blown to obtain high-strength, high-transparency stretch blow-molded bottles, and can also be directly extruded into sheets The material is then thermoformed to produce a hollow container. PET products are transparent, oil-resistant, fragrant, hygienic and reliable, and have a wide range of operating temperatures, so their usage in the packaging field continues to grow. [0003] Before the preform is blown into a bottle,...
