◆ IMPORTANT NOTICE FOR USE IN PROCESSING
Drying
Drying is necessary prior to the melt processing to prevent the resin from hydrolysis. Typical drying conditions are an air temperature of 160-180℃, 4-6 hours residence time.
Suitable for products with high demands on appearance, such as transparent beverage bottles.
Easy injection and blow molding processing, suitable for mass production.
Ensures purity and safety in food and beverage packaging, especially suitable for mineral water and other beverages.
