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.

Packaging plays a crucial role in maintaining product quality, particularly for perishable goods like sponge cake. When issues such as mildew and bag deflation arise, comprehensive testing is essential to identify the root cause.
In this case, Labthink packaging test center employed a series of tests to evaluate the packaging material. The first set of tests focused on the material's barrier properties. Oxygen and nitrogen transmission rates (OTR and NTR) were measured to assess the package's ability to protect the product from oxidation. High OTR and NTR values indicated poor barrier performance, allowing oxygen ingress and nitrogen loss, which can accelerate product deterioration.
To evaluate the package's structural integrity, heat-seal strength and leak tests were conducted. Heat-seal strength determines the package's resistance to opening, while the leak test identifies any vulnerabilities in the seals. Low heat-seal strength and package leakage can lead to product contamination and spoilage.
Finally, headspace air analysis was performed to assess the gas composition within the package over time. Changes in gas composition can affect product shelf life. A decrease in nitrogen and increase in oxygen levels, as observed in this case, can accelerate product degradation.
The test instruments used in this analysis likely include:

Opening Force: This test determines the ease with which consumers can open the package. While excessive force can frustrate consumers, insufficient force might compromise product integrity. Optimizing opening force is crucial for consumer satisfaction and product protection.
Tear Resistance: This property is essential for packages that require easy opening, such as pouches or bags. Tear resistance tests evaluate the force needed to initiate and propagate a tear, ensuring controlled opening without product damage.
Labthink C610H Auto Tensile Tester is professionally applicable to measurement of tensile, peeling, deformation, tearing, heat sealing, adhesive, puncture force, opening force, pulling force and low speed unwrapping force as well as other properties of plastic films, composite materials, soft package materials, plastic flexible tube, adhesives, adhesive tapes, label stickers, medical plasters, release paper, protective films, combined caps, aluminum foils, diaphragms, back sheets, non-woven fabrics, rubber and paper, etc.
Impact Resistance: Packaging often encounters shocks and vibrations during transportation and handling. Impact resistance tests assess the package's ability to withstand these forces, preventing product damage and preserving its quality.
Labthink C670M Falling Dart Impact Tester is suitable for measuring the impact mass and energy of plastic film or sheet when 50% of the sample is damaged under the impact of free falling dart at a given height.
By subjecting packaging to rigorous physical and mechanical testing, manufacturers can identify potential weaknesses, optimize packaging design, and ensure product safety and consumer satisfaction. As regulatory standards become increasingly stringent, continuous investment in advanced testing equipment and methodologies is essential to meet the evolving demands of the food and drug industries.
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!
