How Bag in Box (BIB) Systems Work: FDpack’s Guide to Efficient, Sustainable Packaging

In industries ranging from food and beverage to pharmaceuticals, Bag in Box (BIB) systems have become a cornerstone of modern liquid packaging. At FDpack, we specialize in engineering BIB solutions that combine innovation, sustainability, and reliability. This blog breaks down how BIB systems operate, their benefits, and why they’re revolutionizing liquid storage and dispensing worldwide.

What is a Bag in Box (BIB) System?

A Bag in Box system is a three-part packaging method comprising:

• Flexible Inner Bag(bag-in-box bag): Made of multi-layered, high-barrier films (e.g., EVOH, metallized PET) to prevent oxygen ingress and UV exposure.
• Outer Corrugated Box(bag-in-box box): Provides structural support and branding space.
• Fitment/Valve: Ensures hygienic, leak-proof dispensing.

FDpack’s BIB systems are designed for liquids like wine, juice, chemicals, and pharmaceuticals, offering unmatched freshness and cost efficiency.

How Does a Bag in Box System Work?

1. Filling the Bag

• Aseptic Process: FDpack’s BIB bags are sterilized via gamma irradiation (≥15kGy) and filled in sterile environments, ideal for perishables like UHT milk or wine.
• Precision Machinery: Automated fillers ensure accuracy, minimizing product loss.

2. Sealing & Boxing

• The filled bag is inserted into a corrugated box, with the fitment (tap/spout) threaded through a pre-cut hole.
• FDpack’s boxes are 100% recyclable and customizable with branded graphics.

3. Dispensing

• Users activate the fitment (e.g., push-button tap), allowing gravity-fed dispensing.
• As liquid flows out, the bag collapses, preventing air contact and oxidation.

Why FDpack’s bag-in-box BIB Systems Lead the Market
