Main Features of Tunhe PET Chips

Comprehensive Quality Certification. The company has obtained OHSAS 18001 Occupational Health and Safety Management System, ISO 9001 Quality Management System, and ISO 14001 Environmental Management System certifications. These internationally recognized standards ensure stable production control and consistent product quality.
Wide and Differentiated Product Portfolio. Tunhe offers a multifunctional and differentiated range of PET resin grades for bottle applications. The comprehensive product portfolio covers mineral water bottles, hot-fill bottles, carbonated beverage bottles, edible oil bottles, and other packaging solutions, meeting the diverse requirements of food, beverage, and cosmetic packaging customers.
Excellent Processing Performance. Tunhe PET resin is engineered through controlled modification and formulation to achieve a balanced crystallization rate, ensuring smooth processing and molding. The introduction of modifiers such as isophthalic acid (IPA) effectively reduces crystallization speed, improving process stability and facilitating efficient production operations.
Outstanding Mechanical Properties. The resin features a narrow molecular weight distribution and high overall uniformity. Compared with conventional PET resins of similar intrinsic viscosity, Tunhe PET demonstrates superior mechanical performance. Finished products exhibit excellent strength and toughness, fully meeting the mechanical requirements of demanding packaging applications.
High Hygiene and Safety Standards. It is non-toxic, odorless, hygienic, and safe. It complies with food packaging hygiene standards and can be directly used in food-contact applications, ensuring consumer health and product safety.
Superior Gas and Moisture Barrier Properties. Tunhe PET chips provide excellent barriers against air, moisture, oils, and odors. These properties help effectively preserve the quality of packaged contents and extend shelf life, making the resin particularly suitable for beverages, edible oils, and other sensitive products.
