Why Do Tuna Cans Fail After Retort? The Physics of Metal Packaging Reference Standard: ASTM A623 / ISO 9001:2015 (Standard Specification for Tin Mill Products) Short Answer Empty tuna cans with lids frequently succumb to internal “blackening” and geometric buckling during the 121°C retort process due to sulfur-staining kinetics where protein breakdown releases reactive ions … Читать далее
How Do Surfactants Degrade Plastic Packaging? The Physics of ESCR Reference Standard: ASTM D1693 (Standard Test Method for Environmental Stress-Cracking of Ethylene Plastics). Short Answer Polyethylene (PE) packaging fails in aggressive environments due to macromolecular chain scission caused by surfactants. By utilizing Superior ESCR resins, optimizing PCR blending rheology, and applying in-line flame treatment to … Читать далее
Why Do Retort Tinplate Cans Fail in High-Moisture Foods? Reference Standard: ASTM A623 (Standard Specification for Tin Mill Products) & ISO 16496 (Thermal Shock Resistance Calibration) Short Answer An empty sardine can experiences severe metallurgical and structural stress during 121°C retort processing. The primary failures—corrosion and double seam microleaks—stem from the differential thermal expansion between … Читать далее
