Bag-in-Box (BIB) Packaging: Frequently Asked Questions

Q1: What sizes of BIB bags do you offer?

A: Wuxi Ecopack provides a wide range of BIB bag sizes to suit different needs, including standard 2L, 3L, 5L, 10L, 20L, 220L aseptic bags for industrial use. Custom sizes are also available upon request to fit your specific secondary packaging requirements.MAX width up to 2400mm.

Q2: Are your Bag-in-Box solutions food-safe?

A: Yes, absolutely. All our BIB bags are manufactured using BPA-free, food-grade materials (such as PE, NY, and EVOH). Our production processes comply with international safety standards (FDA/SGS), ensuring they are safe for wine, water, juice, edible oils, and dairy products.

Q3: What type of dispensing taps (fitments) do you use?

A: We primarily use industry-leading fitments, including the Vitop® tap, which is renowned for its excellent oxygen barrier and leak-proof performance. We also offer various butterfly valves and screw caps to match different liquid viscosities and dispensing systems.

Q4: How does BIB packaging help extend the shelf life of wine or juice?

A: The "airless" design is the key. As liquid is dispensed, the inner bag collapses, preventing air (oxygen) from entering the bag. Combined with our high-barrier EVOH layers, this ensures that the product stays fresh for several weeks even after the first glass is poured.

Q5: Does Wuxi Ecopack offer recyclable Bag-in-Box options?

A: Sustainability is a core focus at Ecopack. We are proud to offer mono-material (PE-based) recyclable BIB structures that maintain high barrier performance while being compatible with modern recycling streams, helping your brand reduce its environmental footprint.
