How Vacuum Technology Removes Contaminants from rPET
High-temperature vacuum processes represent the industry standard for removing volatile organic compounds (VOCs) and contaminants from recycled polyethylene terephthalate to ensure it meets food-safety requirements. This thermal-mechanical treatment subjects rPET flakes or pellets to extreme heat under low-pressure conditions, effectively pulling out impurities that could otherwise migrate into food or beverages. Sourcing safe packaging often […]
