When we need a laminated bag, how shoule us change the outer surface of this bag ? OPP or PET ?
Advantages of PET
1. Greater strength resulting in better control for repeat length and slitting size.
2. Higher heat resistance (~250°C) making it the preferred choice for fast speed packing machines (OPP can only withstand up to 180°C)
3. Stronger bonding wit ink and PE resin.
OPP or PET
|Higher heat resistance
|Stronger bonding wit ink
Disadvantages of PET
1. Higher cost in comparison to OPP
