In the context of today's increasing global environmental awareness and the gradual upgrading and landing of the "plastic limit order", degradable plastic bags, as an ideal substitute for traditional plastic bags, are striding towards a broad development prospect, carrying the high hope of alleviating the plastic pollution crisis and reshaping the ecological balance.

Traditional plastic bags use petroleum-based plastics as the main raw material. However, its "stubborn" chemical structure leads to a long degradation process, often taking hundreds of years, a large number of waste plastic bags in the soil, water wanton accumulation, not only damage the soil structure, reduce land fertility. In contrast, degradable plastic bags are like environmental protection "saviour" came into being, cracking this dilemma from the root.

According to the degradation mechanism, degradable plastic bags cover multiple types such as photodegradation, biodegradation, and water degradation. Among them, biodegradable plastic bags use microorganisms to decompose polymers into harmless components such as water, carbon dioxide and biomass, return to the natural cycle, in line with the ecological logic of sustainable development, and are favored. From the perspective of raw materials, renewable resources such as polylactic acid (PLA) and starch-based plastics have become the mainstream material selection, which not only reduces the dependence on limited petrochemical resources, but also reduces the carbon emission "footprint" and realizes the source "green" enabling.

The warm response at the market end also highlights the bright "money scene" of degradable plastic bags. With the deepening of consumer awareness of environmental protection, the preference for green products is increasing day by day, "with environmentally friendly bags, do green things" has gradually become a new fashion of consumption, retail giants such as Walmart, Carrefour, etc., actively shelves degradable plastic bags, e-commerce platforms are full of its figure, catering takeout industry is a batch change, in order to meet the needs of consumers "green dining". According to market research institutions predict that in the next few years, the global degradable plastic bag market size is expected to increase at a double-digit percentage rate, from raw material supply, product processing to terminal sales, all links of the industrial chain wet, release huge commercial value.

It is true that the current degradable plastic bags also meet the "reef" in the promotion of the journey. The cost is higher than that of traditional plastic bags, which restricts the enthusiasm of some small and medium-sized enterprises. The degradation conditions are harsh, requiring specific temperature and humidity and microbial environment, which is difficult to ensure stable degradation efficiency in the natural environment; The market is mixed, there is no lack of inferior counterfeit products, interfering with the normal market order. But the defects do not obscure the flaws, with the emergence of scale effect, technological innovation, and regulatory law network, degradable plastic bags will overcome many obstacles, break the waves in the wave of green economy, reshape the pattern of plastic packaging industry, make "white pollution" become the old shadow of history, and protect the ecological pure land of the earth's home.
