Liquid Egg Bag-in-Box Packaging
Aseptic bulk containment for pasteurized liquid whole eggs, egg whites, and egg yolks.
As a Liquid Egg BIB Packaging manufacturer, Suzhou Jingle Packaging Technology Co., Ltd. supplies aseptic bag-in-box systems designed for the safe storage and dispensing of temperature-sensitive egg products. Our packaging supports food manufacturers, commercial bakeries, hotel kitchens, and institutional caterers who require consistent liquid egg supply with minimal waste and maximum food safety.
Our range covers capacities from 5 to 20 liters, with multi-layer EVOH barrier films and aseptic one-way taps that preserve product quality for up to 12 months unopened under refrigeration. We customize inner bag materials, valve types, and carton specifications to match your filling line and distribution requirements.
Product Range and Applications
We produce BIB packaging for all liquid egg forms, each with specific handling characteristics:
- Liquid whole egg – Standard 5L, 10L, 15L, and 20L bags for bakery and foodservice operations.
- Egg white liquid – Available in 10L and 20L, with tap orifice sizing for low-viscosity flow.
- Egg yolk liquid – Offered in 10L and 20L, with enhanced oxygen barrier to prevent lipid oxidation.
These packages are used in commercial bakeries for bread and pastry production, hotel and restaurant kitchens for breakfast service, food manufacturing for mayonnaise and pasta, and institutional catering for schools and hospitals. They also serve emergency food reserves where long shelf life is critical.
Engineering and Material Specifications
Our bags are constructed with co-extruded EVOH/PE multilayer films, providing high barrier against oxygen, light, and moisture. The total film thickness ranges from 100 to 130 µm, tailored to your product's sensitivity and required shelf life. The outer carton is double-wall corrugated fiberboard with moisture-resistant coating for cold storage environments.

Performance and Safety Advantages
Our BIB packaging is engineered to meet the rigorous demands of liquid egg handling:
- Extended shelf life: Aseptic filling and EVOH barrier enable 12 months at 2–8°C, or 6–9 months at ambient below 25°C, reducing cold chain dependency.
- Microbial protection: One-way tap and collapsible bag prevent air re-entry, maintaining aseptic conditions and reducing spoilage risk.
- Precise dispensing: Integrated taps allow portion control within ±2% accuracy, essential for recipe consistency.
- Waste reduction: Over 99% product evacuation minimizes residual waste, and empty BIB units are compact for disposal.
Configuration and Customization
We offer flexible customization to align with your production and product needs:
- Barrier levels: Choose from standard, high, or ultra-high barrier films depending on your shelf life targets.
- Tap options: Select aseptic one-way valves for extended post-opening use, or standard taps for simpler applications.
- Carton printing: Custom branding and labeling on the outer carton for traceability and marketing.
- Filling equipment integration: Our spouts are compatible with automated filling lines, and we can supply semi-automatic or fully automatic filling machines as part of a complete solution.
Quality Assurance and Compliance
As a China-based factory, we maintain strict quality control throughout production. Our food-contact layers comply with FDA 21 CFR 177.1520 and EU Regulation 10/2011. We hold SGS Quality Management System certification, Kosher certification, and Halal certification (IFANCA). Each batch undergoes sealing integrity tests and barrier performance checks to ensure consistent quality.
Handling and Maintenance Guidance
Proper handling is essential to maximize shelf life and food safety:
- Maintain continuous cold chain at 2–8°C for pasteurized products; avoid temperature fluctuations exceeding 5°C in 24 hours.
- For aseptic products stored at ambient, keep below 25°C and away from heat sources.
- After opening, use within 3–5 days under refrigeration at 2–4°C. Keep tap closed between uses and clean the tap exterior with food-grade sanitizer.
- Ensure carton ventilation holes are unobstructed to allow proper bag collapse during dispensing.
Information We Use to Configure Your Solution
To prepare a precise quotation and sample, we need the following project details:
- Product type: whole egg, egg white, or yolk, and its viscosity if known.
- Required capacity per bag (5L to 20L) and daily production volume.
- Filling process: aseptic or non-aseptic, and whether you have existing filling equipment.
- Storage and distribution conditions: refrigerated, ambient, or mixed.
- Target shelf life and any regulatory compliance requirements.
- Preferred tap type and carton printing specifications.
With this information, we can recommend the optimal film structure, valve design, and carton construction to meet your performance and cost objectives.
Frequently Asked Questions
What is the maximum shelf life of liquid eggs in your BIB packaging?
With aseptic filling and our high-barrier EVOH film, unopened shelf life reaches up to 12 months at 2–8°C, or 6–9 months at ambient temperatures below 25°C. Once opened, product should be used within 3–5 days under continuous refrigeration.
Can you customize the bag size and tap type for our filling line?
Yes, we offer capacities from 5L to 20L and multiple tap options, including aseptic one-way valves and standard dispensing taps with 25mm spouts. We can also provide filling equipment that integrates seamlessly with our bags.
What certifications do your packaging materials hold?
Our food-contact layers comply with FDA 21 CFR 177.1520 and EU Regulation 10/2011. Our factory is SGS certified, and we hold Kosher and Halal certifications, ensuring suitability for diverse markets.
