Product Features

(1) Hot-Fill Compatibility

Designed with low intrinsic viscosity, Tunhe PET TH105 delivers excellent melt flowability for fast preform molding and stable processing. Finished bottles exhibit superior heat resistance, capable of withstanding 85–95°C hot-fill conditions with minimal deformation or shrinkage after cooling.

(2) Food Contact Safety

With acetaldehyde content below 1.0 mg/kg, the resin effectively prevents odor and taste migration. It complies with GB 4806.7 food contact material standards, ensuring flavor integrity and safety for beverage packaging.

(3) Superior Optical & Mechanical Performance

A high L value and low B value provide outstanding transparency and surface gloss. Meanwhile, low carboxyl end-group content (≤ 35 mol/t) enhances hydrolysis resistance and maintains stable barrier properties, helping to extend product shelf life.

(4) High-Speed Line Compatibility

Featuring stable viscosity and minimal fluctuation, Tunhe TH105 resin reduces scrap rates during injection and blow molding. It is well suited for high-speed hot-fill bottle production lines, supporting higher productivity and consistent output quality.
