Raw materials: As consumers pay more and more attention to health, people are concerned about whether the materials used in the crisper itself are healthy. Hygienic and safe materials are harmless to the human body, such as PC materials, PE materials and PP materials. The more common fresh-keeping box materials are PC materials, and the most environmentally friendly heat-resistant glass fresh-keeping box.
Transparent: The crisper is generally made of transparent or translucent material. In particular, the heat-resistant glass crisper is made of high borosilicate glass, which is transparent. In this way, you can easily confirm the contents of the box without opening the box when using it.
Appearance: The high-quality crisper has a glossy appearance, beautiful design, and no burrs.
Heat resistance: The fresh-keeping box has relatively high requirements for heat resistance, and will not deform in high-temperature water, and can even be sterilized in boiling water.
