Bag-in-Box (BIB) Packaging Systems
Heavy-duty corrugated outer carton combined with multi-layer high-barrier aseptic flexible liner bags and precision dispenser tap valves for bulk liquids, syrups, and beverages.
Engineered for High-Barrier Protection & Shelf Pop
Bag-in-Box (BIB) represents the premier modern bulk liquid storage and dispensing format, replacing heavy, rigid steel drums and bulky plastic carboys with a lightweight, eco-friendly two-component architecture. The system pairs an internal high-barrier multi-ply flexible liner pouch with a rigid, high-crush-resistance corrugated carton outer shell. As liquid is dispensed through the pre-welded tap fitment (Vitop, screw cap, or quick-connect QCD valve), the flexible internal bag collapses on itself without allowing ambient air or oxygen to ingress. This vacuum-collapse dispensing prevents product oxidation and bacterial contamination, enabling contents such as wine, post-mix beverage syrups, liquid dairy, and edible oils to remain pristine for up to 6–8 weeks after opening. At QINPACK, our cleanroom plant in Haizhu, Guangzhou fabricates high-performance BIB liquid liners from 1.5L retail wine packs up to 220L (55 gallon) aseptic industrial drums. Utilizing advanced EVOH, metallized PET (VMPET), and heavy-duty co-extruded PE laminations with ultrasonic welded fitments, every bag undergoes ASTM D3078 bubble vacuum leak and seal tensile testing.
Opciones Recomendadas de Producción:
Bag-in-Box Liquid Preservation & Anti-Leak Fitment Mechanics
Ultrasonic fitment hermetic bonding combined with collapsing barrier film preventing liquid oxidation.
Ultrasonic fusion joint between the flange of the dispenser tap and the multi-ply liner prevents ring separation.
EVOH/VMPET barrier layers prevent oxygen ingress, extending shelf life after tap activation.
Multi-layer co-extruded LLDPE inner layer withstands dynamic hydraulic slosh shocks during freight.
Zero bubble emission in submerged vacuum chamber ensures 100% airtight liquid containment.

Why Brands Specify This Pouch Format
Airless Collapse Preservation
The flexible inner liner collapses progressively during dispensing, blocking ambient oxygen and keeping sensitive liquids fresh for weeks after the initial pour.
80% Lighter Freight Weight
Replaces heavy glass bottles and rigid HDPE jugs, slashing transport tare weight and reducing supply chain fuel carbon emissions by up to 75%.
Space-Saving Flat-Pack Transport
Empty liner bags and unerected carton boxes ship completely flat, occupying only 15% of the warehouse volume required by empty rigid containers.
High-Crush Pallet Stacking
Engineered outer corrugated boxes provide rigid rectangular stacking strength, maximizing cube efficiency inside 20ft and 40ft ocean export containers.
Universal Dispensing Tap Options
Pre-welded with industry standard Vitop faucets, push-button taps, or commercial foodservice quick-connect valves for soda fountains and barista stations.
Full 6-Sided Retail Billboard
The outer corrugated box offers six expansive full-bleed graphic panels for 100% full-color brand imagery, barcode, and regulatory compliance notices.
