Bottle Grade PET Chips
Formation of the PET sections
PET belongs to a high molecular compound.It is formed by the condensation of PTA and EG to produce polyethylene terephthalate (PET), and part of the PET is finally generated by underwater digestion.

Characteristics of the bottle-grade PET sections
Bottle grade polyester sections have uniform crystal structure, narrow molecular mass distribution; non-toxic, tasteless, glass-like transparent and luster; good impact toughness and high strength; small gas permeability (i. e., good barrier performance), can extend the shelf life of the beverage; simple processing, small size change or small creep under load; compared to glass, light quality and good safety.

Product introduction
CZ-318 bottle grade polyester chips are aimed at soda bottles, small-packaged edible oil bottles,liquor bottles, medicine bottles, washing cosmetics bottles, wide-mouth bottles and PET sheets, etc.,requiring higher strength, barrier performance, transparency and Specially developed and produced for better processing performance and other unique use performance.

This brand product has the characteristics of low heavy metal content, low acetaldehyde content,good color value and stable viscosity. Due to the unique process formula and advanced production technology, the product has excellent crystallization properties, which can meet the processing requirements of thicker and larger varieties of small-packaged edible oil bottles, wine bottles, soda bottles, medicine bottles, and sheets. , The processing temperature is low, the processing range is wide, the product transparency is good, the strength is high, and the yield is high.

Using Instruction
Bottle sections are widely used in bottle containers; can be used to make food and beverage bottles.Polyester has a certain degree of hydrophilicity, and the pellets are more sensitive to water at high temperatures, thereby reducing the molecular weight of the chips and reducing the mechanical properties of the final product. Therefore, it needs to be dried before melting. The recommended drying conditions are 160-180, the drying time is about 4-6 hours, and the dew point temperature should be controlled below -40 . The recommended barrel injection temperature is 275-295 . During storage and transportation, moisture, dust, sunscreen, mechanical collision; dust, particles, oil and chemicals shall not be mixed; loading and unloading, iron hooks shall not be used to avoid packaging damage.
