The material is food-grade silicone, safe and environmentally friendly, in line with the German and American standards for daily items in contact with food (LFGB and FDA).
Resistant to high and low temperatures, the use temperature range is -40℃ to +240℃. It can be used in refrigerators, microwaves, and electric ovens. Due to the excellent elasticity of silicone, it naturally forms an internal negative pressure state when covering the container, completely isolating the flow of internal and external gases, and has strong sealing properties. When used in the refrigerator to cover bowls, pots, basins, etc., it will not cause cross-flavors. Due to the complete isolation of air from entering, it can achieve a very good fresh-keeping effect.
The thermal conductivity is only 0.27, which is about 1/1000 of that of metal, making it ideal for covering bowls, pots, and basins, resulting in excellent insulation effects.
Silicone, composed of silicon-oxygen bonds, is ultra-durable against aging, with a normal service life of over 30 years.
Based on the sizes of common household containers, a variety of size freshness covers are provided for selection.
