I've encountered a recurring issue with a frozen food product where the packaging's arrow tear sign fails to function correctly on both sides. Based on my extensive experience with similar failures, I suspect that the orientation of the film might be one of the primary root causes.  As a Packaging and Device engineer, I am committed to diligently reporting any packaging-related issues to ensure continuous improvement. If you encounter any problems with packaging or devices, I encourage you to promptly inform the manufacturer or Pintegrity. Your feedback is invaluable as it will significantly contribute to enhancing our packaging and device technology in the future. Together, we can drive innovation and maintain the highest standards of quality in our products.
