Based on criteria most beverage packaging bag is food grade, waterproof, and some need to be lightproof.
Suggestions of material:
Acidic beverages: PET/PE (CPP), BOPA/PE (CPP), PET/VMPET/PE, MOPP/PET/PE
Neutral beverages: PET/AL/CPP(PE), PET/AL/PA/CPP(PE), PET/AL/PET/CPP(PE), PA/AL/CPP(PE)
PH of acidic beverages is <4.5, pasteurized, and generally barrier properties. PH of neutral beverages is >4.5, sterilization, and high barrier properties.
For acidic beverages, PET and PA can provide good barrier properties, pasteurization resistance, and extended shelf life due to acidity.
For neutral beverages, AL provides the best barrier properties, high strength of PET and PA, and high temperature sterilization resistance.
