Custom Bag-In-Box Plastic Valve / Caps / Tube / Taps / Fitments
Precision-engineered dispensing components for Bag-In-Box packaging systems. Food-grade polymer construction with customizable configurations for beverage, dairy, edible oil, chemical, and pharmaceutical liquid dispensing applications.
Custom BIB plastic dispensing components encompass the full range of injection-molded and assembled parts that enable controlled liquid evacuation from Bag-In-Box systems. These include dispensing taps with various flow rate configurations, threaded caps for spout protection, dip tubes for gravity-fed dispensing, connector fitments for pump integration, and specialized valves for aseptic or one-way flow control. Each component is manufactured from food-grade polyethylene or polypropylene polymers selected for chemical compatibility with the target liquid product, whether water-based beverages, high-acid juices, fatty edible oils, solvent-based industrial fluids, or pharmaceutical intermediates. Custom color matching, branding embossing, and dimensional modifications are available to meet specific dispensing equipment interface requirements and brand identity specifications.
Core Advantages
LDPE, HDPE, and PP resin options matched to product chemistry requirements. Silicone gasket seals for high-acid applications, fluorinated polymer components for solvent resistance, and USP Class VI materials for pharmaceutical-grade dispensing.
Tap orifice diameters from 6mm to 25mm provide dispensing flow rates from 0.3 L/min for portion-controlled applications to 8 L/min for high-volume industrial dispensing. Dosing chamber taps achieve ±2% volume accuracy for measured dispensing.
Custom color matching to brand specifications, embossed or debossed logos on tap bodies, color-coded dust caps for flavor identification in multi-flavor beverage systems, and private-label packaging for component distribution.
Components manufactured to fit Scholle, Vitop, BagFresh, and other global BIB connector standards. Custom fitment designs available for proprietary dispensing equipment interfaces with full CAD and 3D prototyping support.

Application Scenarios By Component Type
Common Questions & Technical Support
Q1 How to select the correct tap orifice size for a specific product viscosity?
Orifice selection depends on product viscosity at dispensing temperature. For water-like liquids (1–10 cP), 6–8mm orifices provide flow rates of 1–3 L/min. For edible oils (40–80 cP), 10–12mm orifices maintain 1–2 L/min. For viscous products such as jam, liquid egg, or gear oil (100–5,000 cP), 15–25mm orifices are recommended. BIB component suppliers provide viscosity-to-orifice selection charts and can conduct flow rate testing with customer product samples to validate dispensing performance before production order placement.
Q2 Can BIB taps and fitments be custom color matched to brand specifications?
Yes. Custom color matching is available using Pantone or RAL color standards. Color masterbatch is compounded into the polymer resin before injection molding, ensuring uniform coloration throughout the component. Minimum order quantities for custom colors typically start at 10,000–25,000 units per SKU depending on component complexity. Color-matched dust caps, tap bodies, and connector components are commonly used in multi-flavor beverage fountain systems for rapid flavor identification by service personnel.
Q3 What material certifications are available for pharma and food-grade components?
Food-grade components are manufactured from polymers compliant with FDA 21 CFR 177.1520 (PE) and 21 CFR 177.1520 (PP), with EU Regulation 10/2011 migration compliance documentation. Pharmaceutical-grade components include USP Class VI certification for biocompatibility, USP 661.1 physicochemical testing, and extractables profiles per USP 1663. Certificates of Conformance are provided with each production lot. Drug Master File Type III filing support is available for pharmaceutical component customers.
Q4 How to prevent tap leakage in high-acid or solvent-based product applications?
Standard LDPE tap bodies with EPDM gaskets are suitable for pH 3–11 aqueous products. For high-acid products below pH 3.0 such as vinegar concentrates or citrus syrups, specify taps with silicone gasket seals and acid-stable PP bodies. For solvent-based products such as automotive fluids or industrial degreasers, fluorinated polymer components with PTFE-based sealing elements prevent gasket swelling and tap body degradation. Submit product chemical composition to the component supplier for material compatibility verification before specification finalization.
