Introduction
Foil Barrier BIB Bags utilize the superior barrier properties of aluminum foil, which provides a near-zero Oxygen Transmission Rate (OTR) and Vapor Transmission Rate {WVTR. Suzhou Jingle Packaging laminates the foil layer between structural and food-contact polymer layers, ensuring product purity and preventing corrosion. Foil bags are the gold standard for maximum product protection, often used for high-value or highly sensitive liquids that require the longest possible ambient shelf life.
They are non-transparent, offering complete protection from light-induced degradation (photo-oxidation).
