The production process and ingredients used in traditional plastic bags are gradually eliminated under environmental governance. What is introduced is a degradable plastic bag with environmental protection characteristics. So what plastic bag materials are included in the popular pla degradable plastic formula on the market? Next, let’s take a closer look at the relevant ingredients and see if they are really “environmental friendly” ingredients.
Starch modification
The pla degradable plastic formula contains starch-modified ingredients, which are combined with the improvement of corn starch, and then matched with other ingredients to present a plastic bag with environmental protection characteristics. The degradable plastic bag used as the main material even has a faint smell of corn. This is an indispensable ingredient for many similar degradable plastic formulations. However, due to the difference in the quantity purchased, the cost will also have a certain impact.
PCL
The degradable plastic bag with this composition is used to ensure its better decomposability. This ingredient is fused with starch and cellulose and other materials to make a flexible and environmentally friendly plastic bag. Under the influence of a certain period of time and the environment, this kind of plastic bag will gradually be decomposed, and white pollution will not form. Of course, in addition to these, there are many other ingredients, and these are essential ingredients. Without these two ingredients, it is difficult to guarantee its degradability and environmental protection.
The plastic bag material contained in the pla degradable plastic formula is briefly introduced here. Through the above simple analysis, I believe that everyone has a basic understanding of the production of environmentally friendly plastic bags and knows what ingredients are used in this kind of plastic bags. After all, most of the ingredients used in traditional plastic bags are chemical ingredients.
