Carbonated beverage bottle grade PET Resin CZ-328

Product introduction

CZ-328 have low heavy metal content. low content of acetaldehyde、good color value、 Stable viscosity and

good for processing. With a unique process recipe and advanced production technology,  strengthening the

process control and quality management, the product with excellent isolation property is effective  in protecting

the carbon dioxide from leaking, good in pressure resistance, low temperature processing, wide   scope in processing,

excellent in transparency, high in finished product rate and can effectively prevent bottles  from breaking for the

carbonated drinks which are in storage period and under pressure.

Techncal index

Applications:

Copolyester "CZ-328" polyester chips are TPA-based polyethylene terephthalic  copolymer. It is a high molecular weight

polymer for general use in manufacturing containers. It can be used in the production of making packing bottles for

carbonated soft drink like cola and 3-gallon, 5-gallon big bottles.

Typical processing conditions

Drying is necessary prior to the melt processing to prevent the resin from hydrolysis. Typical drying conditions are an air  temperature  of  165-185 ℃,  4-6  hours  residence  time,  dew-point  temperature   below-40 ℃

Typical  barrel  temperature  about  280-298 ℃ .
