At present, straws are common products in any city in any country, but while straws bring convenience to people's lives, more and more plastic straws and similar products that are discarded at will begin to burden the environment.
Under the pressure of environmental protection and plastic limitation, conventional straws are facing challenges and are eliminated. It is imperative to replace environmentally friendly straws. Green and environmentally friendly polylactic acid degradable straws and paper straws have also emerged.
The origin of two environmentally friendly straws
PLA degradable straw
PLA is a new type of biodegradable material that uses renewable plant resources such as corn, cassava and other crops to extract starch. The starch raw material is saccharified to obtain glucose, which is then metabolized and fermented by bacteria to produce high-purity lactic acid, and then synthesized The method obtains high-molecular-weight polymerized lactic acid, which is then processed and formed into various biodegradable straws with good performance.
Paper straws are made of food-grade paper, which can be degraded in the soil after several months of use.
After the two straws are used, they can be completely degraded by microorganisms in nature, and finally produce carbon dioxide (CO2) and water (H2O), which will directly enter the soil and become organic matter to be absorbed by plants. It will not cause the greenhouse effect and will not pollute the environment. It is a true source To nature, to nature.
Zhejiang straw manufacturers compare the characteristics of two environmentally friendly straws:
1. The material is natural, non-toxic, highly breathable, and will not release any substances harmful to human health;
2. After use, it can be completely decomposed by microorganisms through composting environment and landfill treatment, without causing any impact on the environment;
3. It can replace traditional plastic straws that use petroleum as raw material, the usage is the same, and it is more environmentally friendly and healthier.
4. Because environmental protection straws are more expensive than plastic straws, the price is slightly higher.
PLA degradable straws have a temperature resistance of -10°C to 80°C, which is close to traditional plastic straws, with good stability and no plasticizers.
The temperature tolerance of paper straws is between -10°C and 40°C, and it is easy to dissolve when it exceeds 40°C, which will affect the taste of food, but the color is richer.
