Main Features of Tunhe PET Resin
- Complete quality certification. The company has passed the OHSA18001 occupational safety and health management system certification, ISO9001:2000 quality management system certification, and ISO14001 environmental management system certification, and the product quality is guaranteed.
- Rich product variety. It is a multifunctional and differentiated PET resin sheet for bottles, with a complete range of products, including mineral water bottles, hot can bottles, carbonated beverage bottles, edible oil bottles and other types, which can meet the diverse needs of different fields and different customers such as food and cosmetics packaging.
- Good processing performance. Tunhe PET resin may control the modified components and other methods to make the crystallization rate moderate, which is convenient for processing and molding. For example, the introduction of the modifier isophthalic acid (IPA) can reduce the crystallization rate, which is beneficial to the processing operation of the resin during the production process.
- Excellent mechanical properties. The PET resin produced by it has a narrow molecular weight distribution and overall uniformity. The mechanical properties are better than the existing PET resin of the same viscosity. The products made have good strength and toughness, which can meet the requirements of mechanical properties for application scenarios such as packaging.
- High hygiene and safety. It is non-toxic, odorless, hygienic and safe, and meets the hygiene standards in the field of food packaging. It can be directly used for food packaging to ensure the health and safety of consumers.
- Good air and water barrier properties. Tunhe PET chips has excellent air, water, oil and odor barrier properties, can effectively maintain the quality of the packaged contents and extend its shelf life, which is very important for the packaging of beverages, edible oils and other products.
