网讯: currently, full world polyester output/production volume positive 以两位数 speed rate growth. polyester is main/primary raw materials made formed use plastics bottle tube/pipe from appearance, gloss, still is machine can and quality guaranteed 方面都 is currently most packaging product 之一. use polyester packaging bottle processing technology 1, use polyester raw materials features used for bottle blow molding polyester (PET) raw materials is saturated combined property thermoplastic polyester, main applications machine can indicators is: features viscosity (IV)应 control in 70~85ml/g, make blow molding bottle tool has relatively high machine strong/high degree and transparent property.

PET plastics bottle used for large (large 于2 rise) bottle 体, selection polyester raw materials features viscosity is 70~75ml/g. blow molding use small bottle excellent selection relatively high features viscosity indicators material is 宜. is Raw Materials product types selection and 否, to process molding process parameters and bottle quality excellent poor. therefore, in 出产药 use PET bottle 时, raw materials features viscosity, crystallization temperature degree, cooling speed rate and orientation and other process data is important. this is due to polyester material is types can crystallization polymer, its crystallization speed rate very small, is 6μm/min(max).
