PLA Biodegradable Straw PK Paper Straw
- Nov 07, 2018 -

In the contemporary era, straws are a very important product in any country. However, while the straws bring convenience to people's lives, more and more plastic straws and similar products that are discarded at random have begun to burden the environment. Under the pressure of environmental protection and plastic limit, conventional straws are facing challenges and elimination. Environmentally friendly straws can not be replaced. Green and environmentally friendly PLA degradable straws and paper straws have emerged. Today, Dexuan will take you to know about the two giants of environmentally friendly straws: PLA degradable straws and paper straws.



First, let's take a look at the origins of these two environmentally friendly straws:


PLA degradable straw, PLA (polylactic acid) is a new type of biodegradable material, which is made from starch raw materials proposed by renewable plant resources such as corn. The starch raw material is saccharified to obtain glucose, and then glucose and a certain strain are fermented to produce high-purity lactic acid, and then a certain molecular weight polylactic acid is synthesized by chemical synthesis, and then processed and formed, which has good biodegradability.

The paper straws are made of food grade paper and can be degraded in the soil after a few months of use.


These two types of straws can be completely degraded by microorganisms in nature after use, and finally produce carbon dioxide and water. Directly enter the soil organic matter or be absorbed by plants, will not be discharged into the air, will not cause greenhouse effect, and will not pollute the environment. Really come from nature and return to nature!


Secondly, let's talk about the characteristics of these two types of environmentally friendly straws. Let me first say the same thing:


1. The material is natural, non-toxic, and has high gas permeability. It will not release any substances that are dangerous to the human body;


2. After use, the composting environment and landfill treatment can be completely decomposed by microorganisms 100% without any impact on the environment;


3, can replace the traditional plastic straw with petroleum as raw material matrix, the same method of use, more environmentally friendly and healthy.


4. Because the environmental protection straw is more expensive than the plastic straw, the price is slightly expensive, and it may become an obstacle to the development of the environmental protection straw market.

Then, let's take a look at the differences between the two environmentally friendly straws:


The degradation temperature of PLA degradable straws is between -10 ° C and 80 ° C, which is closer to the traditional plastic straws, and has the physical properties of similar traditional plastic straws and higher stability. But its color is simpler than paper straws;


The paper straw has a temperature tolerance of -10 ° C to 40 ° C. It is easily dissolved when it exceeds 40 ° C, which will affect the taste of the food. But it can be customized with different colors, can be used as decorations, and is more beautiful.



In summary, PLA degradable straws and paper straws are the most popular environmentally-friendly straws in the world, but each has its own characteristics. Customers can choose different environmentally-friendly straws according to their own needs. Finally, Xiaobian reminds everyone: care for the environment, everyone is responsible.
