Ensure Food Safety with Comprehensive Packaging Testing and Analyzing

Packaging plays a critical role in maintaining food quality and safety. However, various issues can arise, impacting product integrity and consumer satisfaction. Four common packaging challenges and their solutions are highlighted below.

Packaging Punctures and Tears Packaging for fresh meat products, such as pork chops, often experiences punctures and tears due to low puncture resistance and flex durability of the composite film. The sharp edges of bones can easily damage packaging materials. To address this, manufacturers should focus on selecting materials with higher puncture resistance and flex durability. Additionally, thickening the material can enhance puncture resistance.

Vacuum Bag Inflation Vacuum-packed meat products, like ground beef, may experience inflation due to low flex durability and high brittleness of the packaging material. Improving flex durability through material selection, optimization of production engineering, and adjusting material thickness can mitigate this problem.

Packaging Barrier Issues Ready-to-eat meals packaged in aluminum composite material can suffer from bag inflation and mildew due to poor barrier properties, flex durability, and seal strength. Enhancing the flex durability of each composite layer, adjusting the thickness of the aluminum layer, and improving the adhesive layer can address these issues. Maintaining airtightness and controlling oxygen transmission rates are also essential.

Labthink C406H Oxygen /Water Vapor Transmission Rate Test System is based on the testing principle of Coulometric oxygen sensor and infrared water vapor sensor. It is designed and manufactured according to ASTM D3985、ASTM F1249，ISO 15106-2 and other relevant standards to provide high precision and high efficiency oxygen and water vapor transmission rate tests for high and medium gas barrier materials. It is suitable for testing the oxygen and water vapor transmission performance of films, sheets and related materials in the fields of food, medicine, medical devices, daily chemicals, photovoltaic, electronic and many others.

Heat-Seal Failures Leakage in ready-to-eat meals packaged in plastic composite film often stems from low heat-seal strength and improper sealing. Selecting materials with good heat-seal properties, especially for products with high heat content, is crucial. Adjusting heat-sealing parameters and preventing package contents from entering the sealing area can also improve heat-seal integrity.

By addressing these packaging challenges through careful material selection, testing, and process optimization, the food industry can enhance product quality, extend shelf life, and reduce waste.

As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films. Labthink encourages collaboration with packaging industry companies for quality control! Visit the website www.labthink.com to learn more!
