What is the difference between PLA degradable straws and paper straws?

Nowadays, straws are particularly important products no matter which country they are in. But while straws bring convenience to our lives, more plastic straws and similar products that are discarded at will are gradually burdening the environment. Under the pressure of heavy environmental protection and limited plastics, conventional straws have been challenged and eliminated. It is imperative to replace environmentally friendly straws. Green and environmentally friendly PLA biodegradable straws and paper straws have also been born. Today, Hengsheng Packaging will take you to understand the similarities and differences between the two giants of environmentally friendly straws: PLA biodegradable straws and paper straws.

Let's first understand the origin of these two environmentally friendly straws:

PLA degradable straws, PLA (polylactic acid) is a new type of biodegradable material, made of the mentioned starch raw materials such as renewable plant resources corn. The starch raw material is saccharified to obtain glucose, and then fermented by glucose and corresponding strains to produce high-purity lactic acid, and then use chemical synthesis method to synthesize corresponding content of polylactic acid, and then process it into shape, which has good biodegradability.

Paper straws are made of food-grade paper, which can be degraded in the soil after a few months of application.

These two straws can be completely degraded by microorganisms in nature after application, and eventually carbon dioxide and water are generated. Directly enter the soil organic matter or be absorbed by plants, and will not be discharged into the air, will not bring about the greenhouse effect, and will not pollute the environment. Truly do it comes from nature and belongs to nature!

Secondly, let's talk about the characteristics of these two environmentally friendly straws, the same points:

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

2. After application, it can be completely dissolved by microorganisms through composting environment and landfill treatment, and will not bring any impact on the environment;

3. It can replace the traditional plastic straws that use petroleum as the raw material matrix, the operation method is the same, and it is more environmentally friendly and healthier.

4. Since environmentally friendly straws are more expensive and slightly more expensive than plastic straws, they may also become an obstacle to the development of the environmentally friendly straws market.

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

PLA degradable straws have a temperature resistance of -10°C to 80°C, which is closer to traditional plastic straws, and has the same physical properties as traditional plastic straws, and has higher stability. But its color is simpler than that of paper straws;

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 it can be customized in different colors, and can be used as decorations, which is more beautiful.

In general, PLA biodegradable straws and paper straws are both popular environmentally friendly straws, but they have different styles. Customers can choose different environmentally friendly straws according to their needs.
