PET CHIPS BOTTLE GRADE WK-811 - High-Quality Bottle Grade PET Chips for Packaging

PET Polyethylene terephthalate

It has the characteristics of good heat resistance, low moisture absorption, good chemical and weather resistance, good electrical properties, high dielectric strength and dimensional stability. It also has unique characteristics, such as low crystallization degree, good performance for processing, and environment-friendliness. Especially in the content of acetaldehyde,heavy metal or ash.

Product Characteristics

Excellent Thermal Resistance: WK - 811 PET chips are based on TPA - based polyethylene terephthalic homopolymer, which has good thermal resistance properties. It can meet the requirements of hot - filling beverages with a filling temperature below 90 °C, ensuring the original flavor of the packaged food.

Good Physical and Chemical Properties: The intrinsic viscosity is 0.790 ± 0.015 dl/g, and the acetaldehyde content is ≤ 1.0 μg/g. It has a high L - value (≥ 83.0) and a low B - value (≤ - 0.5), indicating good color characteristics. The melting point is 251 ± 2 °C, and the moisture content is ≤ 0.20%. These properties ensure the stability and quality of the product during processing and use.

Good Processability: It has excellent processing performance and compatibility, and can be widely used in various mainstream bottle - making machines. It has good fluidity, which can reduce processing energy consumption, improve production efficiency and yield.

Applications
Beverage Packaging: It is mainly used in the production of bottles for tea, fruit juice, plant extract beverages, sauce/vinegar, and other products that require hot - filling and sterilization processes.

Compared with glass bottles, the beverage bottles made of WK - 811 are not fragile, have a low production loss rate, are easy to color, are lighter in weight, and are recyclable.

Other Packaging: In addition to beverage packaging, PET chips of this grade can also be used for the packaging of some food and daily chemical products, such as the packaging of edible oils, sauces, and cosmetics, taking advantage of their good barrier properties and physical and chemical stability.

Advantages
High Quality and Safety: Complies with relevant regulations such as China's GB 9685, GB 4806.6, (EU) No 10/2011, and US FDA 21 CFR 177.1630, ensuring the safety and quality of packaged food and beverages.

Cost - effective: Due to its excellent performance, it can help manufacturers improve production efficiency, reduce production costs, and at the same time ensure the quality of packaging products, so it has a good cost - performance ratio.
