Food-grade plastic, silicone, stainless steel, which material is the most safe, cute and practical children's lunch box?

1. Safety

food-grade silicone: inorganic polymer colloidal material condensed from silicic acid, the main component is silica, chemically stable, non-combustible, insoluble in water and any solvent, non-toxic and tasteless. In addition to strong alkali, hydrofluoric acid, does not react with any substance. Silicone tableware is resistant to high temperature 240 ℃ without deformation, low temperature -40 ℃ without hardening, can well protect the food temperature, reduce temperature change and loss. In addition, silicone tableware is soft, flexible, resistant to twisting and not deformed, and will not hurt children due to breakage.

Food-grade plastics: common food-grade PP plastic safety, heat resistance up to 100 ℃ or more, good chemical stability. However, some plastic materials such as polycarbonate (PC), there is bisphenol A, may affect the baby's reproductive system and brain development, so baby bottles have been banned the use of bisphenol A. Milk amine (MF) material, although higher safety, but may contain formaldehyde, melamine and heavy metals and other pollutants.

Food-grade stainless steel: 304 grade or 316 grade stainless steel has excellent corrosion resistance and high temperature resistance, and is not easy to precipitate heavy metals. But stainless steel thermal conductivity, easy to scald the child, and can not hold acidic food for a long time, otherwise it is prone to chemical reactions.

2. Lovely design

Food-grade silicone: colorful, trendy style, can be made into a variety of lovely shapes, such as cartoon images, animal shapes, etc., loved by children.

Food-grade plastic: Although it can also be made into a variety of colors and shapes, but compared to the silicone material, its softness and elasticity is slightly inferior, the degree of cuteness may be slightly lower.

Food-grade stainless steel: stainless steel material itself is more difficult to make into a particularly cute shape, and a single color, usually silver or gold-based, relatively low degree of cuteness.

3. Practicality

Food-grade silicone: can be folded or kneaded, easy to carry and store. At the same time, silicone tableware is easy to clean, not easy to adsorb oil and odor, keep clean and sanitary.

Food-grade plastic: plastic tableware is lightweight and colorful, loved by parents and babies. But plastic is easy to aging, deformation and brittle, and may release harmful substances, so it needs to be replaced regularly.

Food-grade stainless steel: stainless steel tableware scrub good, lightweight, scratch-resistant and easy to carry. However, stainless steel tableware has a strong thermal conductivity, and you need to pay attention to avoid burns when using it.
