Biodegradable tableware refers to tableware that can undergo biochemical reactions under the action of microorganisms (bacteria, mold, algae) and enzymes in the natural environment, causing changes from appearance mold to inner quality, and eventually forming carbon dioxide and water. The main use of materials are divided into two kinds: one is made of natural materials, such as bagasse, paper products, straw, starch, etc., biodegradable, also known as environmentally friendly products; the other is made of plastics as the main ingredient, adding starch, photosensitizers and other substances.
Even biodegradable tableware is not a short period of time. Many degradable products claim that the degradation time is three to six months, but in fact this is determined in the laboratory standard environment, in the natural environment, degradation by temperature, humidity and many other factors, such as you put the lunch box to no water, then it is also difficult to degrade”, in natural conditions, degradable products need at least one year to degrade.
So how to identify biodegradable tableware?
First of all, to see whether there is a QS logo and number on the lunch box; secondly, but also to see whether the surface of the lunch box is smooth, there are no impurities or black spots. In general, the transparent plastic lunch box is the use of pure polypropylene (PP) production, the safety factor is relatively high; brightly colored lunch boxes, it is possible to use waste plastics, so the darker the color is more unsafe.
Second touch, is to feel the strength of the lunch box, the use of recycled waste or a large number of industrial-grade calcium carbonate, talcum powder production of lunch boxes, the strength is generally very poor, gently tear on the rupture.
Three smell, is to smell the lunch box with or without odor, qualified lunch box is not smell out the flavor.
