Custom 3L, 5L, 10L & 20L Bag-in-Box (BIB) Barrier Liquid Pouches with Oxygen-Lock Dispensing Tap
FlexPouchMFG™ engineers dual-web 3L, 5L, 10L, and 20L Bag-in-Box (BIB) flexible bladders equipped with 32mm Vitop®-compatible tamper-evident dispensing taps, high-flow dairy/syrup valves, or aseptic screw glands. Constructed with a flex-crack-resistant outer EVOH-BOPA/mLLDPE barrier web plus a free-floating food-grade metallocene PE inner bladder, our BIB pouches keep wine, cold-brew coffee concentrate, extra-virgin olive oil, liquid egg, and post-mix beverage syrups fresh for 6–12 weeks AFTER opening while cutting shipping weight by 84% vs glass or rigid Jerrycans.
"Single-ply Bag-in-Box bladders develop flex-crack pinholes at the folds during ocean transit. By pairing a 95µm EVOH-BOPA/PE outer barrier web with an independent 65µm ultra-tough metallocene PE inner pillow and 360° gland thermal welding, our 3L–20L BIB bags pass 1.8m corrugated drop tests with zero leakers."
