The use of degradable and environment-friendly tableware is very common. The high-quality secondary lunch box will not affect people's health and life during use. So how do we determine its quality?
1. In terms of color, the transparency of high-quality degradable environmental protection tableware is several times that of glass products, and the surface is smooth. The low-quality degradable environmental protection tableware, due to the use of recycled raw materials, has low transparency and dull surface luster.
2. In terms of hardness, two high-quality degradable environmental protection tableware can withstand the weight of an adult (about 130-140 kg) when placed upside down.
3. From the perspective of cleaning, as degradable and environment-friendly tableware is degradable, it is only necessary to check whether there are water stains, residues and fingerprints before use to determine whether it is the tableware used for the second time.
4. Different from smell, high-quality degradable environmental protection tableware is non-toxic and tasteless. There is no peculiar smell when the water is boiled. This is the guarantee of consumers. Poor degradable environmental protection tableware will have a pungent smell, which is harmful to human health.
5. Materials. I. Standard tableware: 100% polypropylene food grade new material, environmental protection, safety and zero addition. (The thickness of pure PP material is uniform, the primary color is transparent, and the bending is elastic and ductile) 2. Poor quality lunch box: recycled materials are added with non food grade filler, or excessive added and mixed. (Most of them are grayish black, and the color and thickness are uneven after the filler is added. Generally, the filler is white or black, and the cover is processed into soft and thin transparent PS material.)
