100% Degradable Materials Will Soon "Dominate" The World

Market of degradable materials

The excessive use of plastic products has caused huge resource waste and environmental problems. In recent years, with the implementation of the "plastic restriction order", the introduction of government policies and the improvement of public awareness of environmental protection, the market demand for degradable materials and products has gradually increased. So how should consumers choose the products of various degradable materials on the market? This article will give you a detailed introduction.

1. What is degradable plastic?

The degradable plastic is the key material to replace the existing plastic, and is the ideal substitute to solve the white pollution. Biodegradable plastics are the main varieties of degradable plastics. Generally, the degradable plastics we hear refer to biodegradable plastics. Because they can fundamentally solve the problem of white pollution, they have attracted attention from all parties.
At present, the real biodegradable plastics on the market are mainly "compostable plastics", which are usually made of poly (lactic acid) (PLA), poor interpenetration), poly (adipic acid)/butylene terephthalate (PBAT) or PLA+PBAT+starch.

2. Classification of degradable plastics

According to the classification of degradation mode, biodegradable plastics have the strongest applicability. The ideal biodegradable plastic is a kind of polymer material with excellent use performance,which can be completely decomposed by environmental microorganisms after being discarded, and finally become an integral part of the carbon cycle in nature.

According to the source of raw materials, they can be divided into bio based PLA, PGA and PHA, and petroleum based PBAT, PBS and PCL. PLA is currently the most widely used type of degradable plastics.

Biodegradation can be divided into partial degradation and complete degradation ( according to the degree of degradation. PE/starch mixed plastics can only achieve partial degradation, while representative biological polylactic acid (PLA) can achieve complete degradation.

Such products as disposable paper cups, paper takeout tableware, garbage bags and shopping bags, which are closely related to our lives and are in great demand, have gradually become "degradable" and are the trend of the times. They will eventually replace traditional plastic products and become the "mainstream".

There are all kinds of disposable paper cups on the market. How are they made?

The materials of disposable paper cups usually include white cardboard, special paper for paper cups, kraft paper and PLA biodegradable paper.

As mentioned above, PLA, as a degradation raw material, is now widely used to make paper cups, paper boxes, paper bags, etc. To obtain PLA paper cups, you first need the coated paper of PLA used to make paper cups.

First, the cup manufacturer will melt the PLA raw materials by heating, and then cover the paper sheets by the machine. After the paper cups are completely cooled and bonded, they can be used to make paper cups,
  pla coated paper ( has good biodegradability. After use, it can be completely degraded by microorganisms in the nature, and finally generate carbon dioxide and water, which does not pollute the environment. It is very beneficial to protect the environment and is recognized as an environmentally friendly material. Compared with traditional pe coated paper products, PLA coated paper products can be recycled after use. In the long run, it will have more development potential and be more popular with consumers. In order to respond to the concept of safety, environmental protection and sustainable development, the future market must belong to PLA.

Hunan Green Star Biotechnology Co., Ltd. specializes in the production of fully biodegradable coated paper (PLA coated paper and water-based coated paper) - fully  biodegradable film bags (shopping bags, garbage bags, vest bags, roll bags, etc.). The company has obtained the "DIN CERTCO Certificate", "SGS coated paper food grade inspection", "National Plastic Product Quality Supervision and Inspection Center (Beijing) film bag inspection report", the first enterprise in Hunan to obtain Hainan electronic supervision code, the first batch of replaceable (degradable) products certification enterprises in Hunan Province, etc., providing more guarantee and more authoritative certification for enterprises that need film bags (shopping bags, packaging bags, etc.).
