G158 A is a functional PET product that changes the molecular structure of PET through synthesis means, thus reducing the PET crystallization rate and improving the transparency
Injection molding processing liquidity is good, the product has high transparency (4 mm), excellent chemical resistance.
Meet California class 1 # recovery indicator ; fully recyclable ( mechanical and chemical ) during PET recovery.
Can be used for food packaging and food contact substances; provide FDA,ROHS,PAHS TEST REPORTS.
