High transparency and durability

PET (polyethylene terephthalate) material has excellent transparency and glossiness, allowing for intuitive observation of the remaining amount and freshness of eggs. It also has high impact resistance (3-5 times the folding resistance of other films) and chemical corrosion resistance, making it suitable for long-term storage.

Environmental friendliness: Some products use 100% recycled PET (r-PET) or new PET, which meets food grade safety standards (such as FDA certification), is non-toxic and odorless, and can directly come into contact with food.

Barrier performance: Low permeability to oxygen and water vapor, combined with breathable window design (such as USAMI model), can adjust internal humidity, delay bacterial growth, and extend shelf life to one month.

Temperature adaptability

PET material has a wide temperature resistance range (-70 ℃ to 150 ℃), and can withstand high temperature disinfection or low temperature freezing in the short term, suitable for different seasons and transportation environments
