PET Chips CSD Bottle Grade

1. What are CSD Bottle Grade Polyester Chips?

CSD bottle grade polyester chips are a high-quality PET plastic material specifically designed for the production of carbonated beverage bottles. They possess excellent gas barrier properties, mechanical strength, and transparency, effectively preventing the escape of carbon dioxide from beverages.

2. How do PET chips CSD bottle grade differ from the water bottle grade?

PET chips CSD bottle grade have a higher intrinsic viscosity (IV value), superior crystallinity, and lower acetaldehyde content than water bottle grade polyester chips, meeting the specific requirements of carbonated beverage bottles for strength, transparency, and flavor retention.

3. What is the IV value of CSD bottle grade PET resin?

The IV value of CSD bottle grade polyester chips is generally higher than 0.84. We can provide IV 0.85 PET, IV 0.870 PET, and IV 0.875 PET from well-known Chinese polyester chip manufacturers such as JADE, Wankai, Hainan Yisheng, China Resources, and Tunhe.

4. Why do carbonated beverage bottles require polyester chips with a higher IV value?

The IV value directly determines the bottle’s burst pressure resistance. Carbonated beverages contain approximately 3-4 atmospheres of CO₂ pressure, requiring the bottles to withstand this pressure without deformation or breakage.

5. Why must PET chips CSD bottle grade be used?

The pressure in carbonated beverages necessitates the following properties in the polyester chip raw materials:

High compressive strength to prevent bottle expansion and deformation.

Excellent gas barrier properties to prevent CO₂ leakage.

Low acetaldehyde content to avoid affecting the beverage’s flavor.

Good resistance to stress cracking.

6. What is Fast reheat grade PET resin

Fast Reheat Grade PET chips (like Wankai WK-851, CR-8828F) is a premium CSD bottle grade polyester resin designed for fast reheat applications, ideal for producing bottles and containers that require quick and uniform heating for blow molding. It can absorb infrared (IR) radiation in reheat ovens much more quickly and uniformly, offering cost efficiency, and reduced cycle times in packaging processes.
