What is the difference between biodegradable straws and ordinary plastic straws and paper straws
With the continuous development of plastic restriction and banning, the environmental pollution problem of disposable plastic products has gradually become prominent. Now, the emergence of biodegradable materials may effectively solve this problem.
Taking disposable straws as an example, disposable straws have undergone a process from traditional plastic straws, paper straws to biodegradable straws. So what is the difference between them?
Most of the traditional plastic straws are made of PP material, which is characterized by high temperature resistance, low price, transparent and odorless. Of course, the shortcomings are also obvious. According to statistics, the annual habitual use exceeds 10 billion, and plastic pollution has become its biggest hazard.
In terms of raw materials, paper straws are actually biodegradable straws. After all, paper itself is also biodegradable. Paper straws are slightly more expensive than traditional PP straws. The reason why they are gradually phased out is that they have poor taste, especially when they are soaked in liquid, they will become soft, which will seriously affect smoking.
Biodegradable straws generally refer to PLA straws, and some high-temperature resistant biodegradable straws also contain PBS. Both PLA and PBS are biodegradable raw materials, which effectively guarantees the degradation performance of the final product. The biodegradable straw not only meets the degradable performance, but also has almost the same taste as the PP straw. The only drawback is that it is too expensive.
Of course, based on various factors, PLA biodegradable straws have been widely recognized by everyone, and traditional PP straws and paper straws are gradually being phased out in the market. Author: Vsugla https://www.bilibili.com/read/cv12854714 Source: bilibili
