Introduction
Cold Filling BIB Packaging is the simplest and most common application for Bag-in-Box, used when the product is either already pasteurized, requires refrigeration, or is not susceptible to microbial growth (e.g., high-alcohol or high-sugar items). Suzhou Jingle Packaging provides a wide range of film structures, from simple PE non-barrier films to high-barrier EVOH/Foil, depending on the required shelf life. The process is straightforward, using semi-automatic or rotary fillers without the need for complex thermal sterilization.
Cold filling minimizes energy consumption and is suitable for most beverages and non-food liquids.

Logistics & Global Compatibility
-
Broadest Application: Suitable for most non-food and ambient-stable food liquids worldwide.
-
Global Equipment Base: Cold-fill bags are compatible with the largest installed base of BIB fillers globally.
-
Regulatory Compliance: Materials meet all food contact standards (FDA, EU) for cold-filled foods and beverages.
-
Logistics Chain: Reliance on refrigeration or effective barrier films dictates the long-distance cold chain requirement.
FAQ
- Q: Is cold filling less safe than hot filling?
- A: Not if the product is already microbiologically stable (e.g., pasteurized before filling, high alcohol, or high sugar) or if it is immediately refrigerated after filling.
- Q: Why is cold filling used for wine instead of hot filling?
- A: Wine's flavor profile is highly sensitive to heat. Cold filling (with a good barrier bag) preserves the delicate aromas and tastes.
- Q: Can a high-barrier bag be cold-filled?
- A: Yes. High-barrier films (EVOH or Foil) are commonly used in cold-fill applications to ensure protection from O₂ over an extended ambient shelf life.
