Is The Cost Of Biodegradable Tableware High?

Faced with increasingly prominent environmental problems, biodegradable daily necessities have attracted a lot of attention, including disposable tableware made of paper, wood, straw, corn starch, and biodegradable plastics. However, it has been found that disposable chopsticks and other wooden tableware are limited in use due to resource waste, while other biodegradable tableware has not yet become popular. Instead, crystal tableware is being promoted with high recycling value. Let's analyze the current situation and prospects of biodegradable tableware together.
Experts suggest that biodegradable tableware can be identified through several methods such as "looking, smelling, and tearing":
First, check if there is a QS identification and number on the food box; Secondly, it is also necessary to check whether the surface of the food box is smooth and free of impurities or black spots. Generally speaking, transparent plastic lunch boxes are produced using pure polypropylene (PP), which has a relatively high safety factor; A brightly colored lunch box may have used waste plastic, so the darker the color, the less safe it is.
Second touch is to touch the strength of the food box. Food boxes produced using recycled waste or adding a large amount of industrial grade calcium carbonate and talcum powder generally have poor strength and can easily rupture with a gentle tear.
Three sniffs means sniffing the food box to see if there is any odor. A qualified food box cannot smell any odor.
The characteristics of a "black lunch box" can be summarized as six rhymes: soft and fluffy when pinched, easy to tear and burst, pungent and odorous when smelled, easily deformed and leaking when exposed to heat, paraffin marks when folded, and sinking when torn and submerged in water. As long as you remember the rhyme above, you can easily distinguish whether a disposable lunch box is qualified.
