How to Troubleshoot Common Issues in MAP Tray Lidding Film Application

The increasing demand for fresh and preserved food has made the application of modified atmosphere packaging (MAP) tray lidding films essential for manufacturers. Yet, users often encounter challenges such as improper sealing, film adhesion issues, or moisture infiltration. As a seasoned MAP Tray Lidding Film supplier, we understand these pain points and have developed solutions to enhance your packaging processes. Today, we will explore real user stories, common problems, and actionable steps to troubleshoot issues in your MAP lidding film application.

Understanding the User Experience: Common Pain Points

Users typically face three major challenges: films not adhering properly, creating leaks in the packaging, and product spoilage due to inadequate atmospheric conditions. For instance, a local deli reported a 27% increase in spoilage rates when their MAP tray lidding films were not installed correctly. The need for effective sealing becomes apparent as your business scales, making it essential to address these problems directly.

Required Preparation: Tools and Materials Needed

• MAP Tray Lidding Film: Choose high-quality films such as those from Anasheen that align with your product needs.
• Sealing Machine: A pneumatically operated or thermal sealing machine to ensure effective sealing.
• Moisture Meter: To monitor humidity levels within the packaging.
• Temperature Logger: To maintain and record the temperature during storage.

Step-by-Step Guidance for Troubleshooting MAP Tray Lidding Film Issues

1. Inspect the Material: Start by examining the lidding film for any visible defects, such as holes or irregularities. Using films from reputable suppliers like Anasheen will reduce these instances.
2. Check the Sealing Machine: Ensure that your sealing machine is properly calibrated. Adjust temperature settings according to the manufacturer’s specifications; for instance, some films require temperatures around 350°F for optimal results.
3. Monitor Environmental Conditions: Use a moisture meter to confirm that the packaging moisture levels fall within the acceptable range, ideally below 5% for dry products.
4. Perform a Seal Integrity Test: Conduct a burst test to evaluate the seal’s durability. A properly sealed package should withstand pressures of up to 2 psi without leaking.
5. Adjust Atmosphere Parameters: Ensure that the gas compositions (usually a blend of nitrogen and carbon dioxide) are set to the recommended levels based on your food types; for instance, 80% nitrogen and 20% carbon dioxide is ideal for perishable goods.
6. Document and Assess: After applying these steps, maintain records of the adjustments made and any improvements observed in packaging integrity to refine future processes.

Common Errors and Solutions

Error 1: Incomplete Sealing

Many users report incomplete seals which can lead to contamination. This often occurs due to incorrect pressure settings. Solution: Increase the pressure by 15% on your sealing machine, and retest the film.

Error 2: Film Adhesion Problems

Some manufacturers face issues with film adhesion to the trays. This can be caused by improper cleaning of the trays. Solution: Ensure all trays are free from oils or residues, and clean them using a non-abrasive cleaner before application.

Error 3: Inadequate Storage Conditions

Storage temperatures can affect the MAP film's performance. For example, one company found that their stored products had reduced shelf life when temperatures exceeded 75°F. Solution: Regularly monitor storage conditions using a temperature logger to maintain optimal conditions.

Summary and Suggestions

Troubleshooting MAP tray lidding film applications requires an understanding of both the material properties and the environment in which they are used. Always use high-quality materials, monitor your sealing processes closely, and maintain proper storage conditions to ensure the longevity and quality of your food products. By applying these steps, users can effectively resolve issues and optimize their packaging processes.
