Oxygen-Scavenging Film BIB

Specification Table: Scavenger Liners

Common Questions & Answers (FAQ)

• Q: Is the scavenging agent safe for food contact?
• A: Yes. The active layer is embedded in an intermediate film layer, fully separated from the food contact PE layer, and undergoes rigorous non-migration testing.

• Q: Does the scavenger capacity run out?
• A: Yes. The agent consumes a finite amount of oxygen over time. Bags are engineered with sufficient capacity to last the entire targeted shelf life of the product.

• Q: How do I store these bags before filling?
• A: They must be stored in oxygen-barrier packaging (e.g., foil overwrap) to prevent the scavenger from being "used up" by the surrounding air before the bag is filled and sealed.

Specification Features

• Scavenger Uniformity: Advanced extrusion techniques ensure the active agent is distributed uniformly across the entire film surface for consistent performance.

• Humidity Tolerance: The film system is designed to perform efficiently even under varying internal humidity levels caused by the liquid product.

• Residual Scavenger Testing: A quality control protocol to verify the remaining, unused scavenging capacity in the film roll before production begins.

Production Process and Cooperation Advantages

• Performance Modeling: Using predictive models to calculate the required scavenging capacity based on product volatility and filling line conditions (e.g., residual O2 in headspace).

• Supply Chain Management: Implementing specialized logistics to ensure that the active film reels are delivered in hermetically sealed, short-window shipments.

• Joint Patent Development: Collaboration on proprietary film/scavenger formulations to give clients a unique, protected market advantage.

• Scavenger Effectiveness Reporting: Providing detailed reports showing the oxygen concentration curve within the package over a 12-month period.
