What are the raw materials used in the extrusion series of PLA degradable blister sheets?

Disposable degradable tableware made of natural materials is also called biodegradable tableware. Biodegradable tableware is a relatively advanced environmental protection product. It uses starch as the main raw material, adds one-year-growing plant fiber powder and special additives, and is processed by chemical and physical methods to make biodegradable fast tableware. There are two main raw materials used in degradable disposable tableware. One is made of natural materials, such as paper products, straw, starch, etc., which are degradable and are also called environmentally friendly products; the other is plastic as the main component. , made by adding starch, photosensitizer and other substances. Therefore, the degradable lunch box machine generally uses the above-mentioned raw materials to manufacture disposable tableware.

The raw material of such disposable tableware is degradable plastic, which is the main raw material of the degradable lunch box machine. The so-called degradable plastic is to add a certain amount of additives in the production process of plastic, such as photosensitizer, starch and other raw materials. In this way, the degradable plastic product can be broken down into pieces after being used up and discarded and exposed to nature for three months, thereby improving the environment at least visually. But the biggest flaw of this technology is that these fragments can't continue to degrade, but just change from large pieces to small pieces of plastic, which cannot be fundamentally up to the task of eliminating white pollution.

Since starch is a biodegradable natural polymer, it can be decomposed into glucose and water and carbon dioxide under the action of microorganisms. In addition, the material blended with it is also a fully degradable material, so it can be said that it has no impact on the environment. The main source of raw starch production can be corn, potatoes, sweet potatoes, cassava and other annual growing plants. Naturally, biodegradable tableware is not without its shortcomings. For example, most of the production raw materials are food crops, and there are problems such as mildew resistance that need to be solved.
