Aseptic BIB for Dairy and Low-Acid Liquids

Specification Table: Aseptic Liners

Common Questions & Answers (FAQ)

• Q: What is the difference between Hot-Fill and Aseptic BIB?
• A: Hot-Fill relies on the product's high acidity to achieve sterility. Aseptic relies on sterilizing the product (UHT) and the packaging separately, then filling in a sterile environment, essential for low-acid foods.

• Q: How do I dispense an aseptic bag without breaking the sterile barrier?
• A: Aseptic bags use a matching sterile connector (fitment) on the dispensing equipment, which sterilizes the connection point before puncturing the bag's septum, maintaining the sterile chain.

• Q: Are the aseptic bags suitable for liquids with small particulates?
• A: Yes, but the fitment size must be larger (e.g., 2-inch) and the product must have passed through a UHT system designed to handle particulates without clogging.

Specification Features

• Pin-Hole Free Foil: Utilizing ultra-low gauge foil and double-pass inspection to guarantee zero pin-holes, which are failure points for the oxygen and light barrier.

• Fitment Welds: Aseptic bags require a wider, more structurally robust heat seal around the fitment to withstand both sterilization chemicals and handling stress.

• Internal Surface Finish: The internal PE layer must be exceptionally smooth to minimize potential niches for microbial adherence prior to sterilization.

Production Process and Cooperation Advantages

• Aseptic Line Integration: Close collaboration with aseptic filler manufacturers (e.g., B+S, Scholle) to ensure 100% compatibility of our bag fitment dimensions and materials with their sterilization heads.

• Microbiological Validation: Providing comprehensive microbial challenge test data to prove the bag's ability to maintain a 10^-6 SAL under simulated distribution conditions.

• Barrier Optimization Service: Tailoring the EVOH or foil thickness to match the client's required shelf life and their specific product's sensitivity to oxygen and light.

• High-Speed QC: Implementing continuous film barrier integrity testing (e.g., spark testing) inline during bag manufacturing to ensure the highest quality before the bags leave the clean production environment.
