What types of food packaging tests are there?

Packaging Material Hygiene and Safety Testing
Total migration, heavy metals, potassium permanganate consumption, and decolorization test
Harmful metal elements (barium, cobalt, copper, iron, lithium, manganese, zinc, etc.)
Additives, auxiliaries, and migration levels of harmful substances (such as mineral oils, plasticizers, bisphenols, nonylphenols, etc.)
Organic Volatile Compounds and Residual Solvents (such as Formaldehyde, Acetaldehyde, Benzene-Based Solvents, etc.)
Microbial Testing of Packaging Materials
Total colony count, molds and yeasts, coliforms, and pathogenic bacteria (such as Salmonella, Shigella, Staphylococcus aureus, and hemolytic Streptococcus)
Packaging Material Barrier Performance Testing
Water vapor transmission rate, oxygen transmission rate, carbon dioxide transmission rate, nitrogen transmission rate, and more
Packaging Material Aging Performance Testing
Photostability performance, thermal aging performance
Physical and Mechanical Property Testing of Packaging Materials
Tensile properties, tear resistance, puncture resistance, light transmittance and haze, peel strength, heat-seal strength, compression resistance, oil resistance, cold resistance, and more
Transportation Simulation Test
Vibration tests, low-pressure vibration tests, shock tests, drop tests, and more
Environmental Simulation Testing
Low-temperature and low-humidity testing, high-and-low temperature stacking tests, low-pressure vibration tests, temperature-humidity cycling tests, high-temperature and high-humidity testing, low-temperature testing, high-temperature testing, and high-and-low temperature low-pressure tests
Aging tests, solar radiation (sunlight) tests, moisture-proof tests, anti-mold tests, and sterility tests
Turnover Equipment Testing and Inspection
The pallets are fully equipped with testing capabilities, compliant with national, U.S., ISO, and other international standards.
Turnover boxes meet industry standards and have full testing capabilities.
