Waterproof Tear Resistant Functional PET G159 Recyclable
G159 is a functional PET that changes the molecular structure of PET through synthetic means to improve transparency. The product is mainly used for high concentration Baijiu bottle mouth and injection blow bottle packaging, transparent boxes, various special transparent components, etc.
Excellent transparency and processing
Injection molding processing liquidity is good, the product has high transparency (3mm), excellent chemical resistance.
Recyclable
Meet California Class 1 # recovery criteria; fully recoverable (mechanical and chemical during PET recovery).
Safety and environmental protection
Can be used for food packaging and food contact substances; provide FDA,ROHS,PAHS(PAHs)test reports.
