在餐盒使用量巨大的餐饮行业，各种类型的可降解餐盒可谓是百花争艳。一款以植物纤维为主的环保餐盒却悄然脱颖而出，俏销市场。那么玉米淀粉餐盒和其他的植物纤维餐盒是否一样呢？

In the catering industry, where the use of lunch boxes is huge, various types of degradable lunch boxes can be described as a hundred flowers competing for beauty. An eco-friendly lunch box based on plant fiber has quietly stood out and sold well in the market. Is the corn starch meal box the same as other vegetable fiber meal boxes?

从长期来看，国内环保意识增强，可降解塑料使用的领域拓宽;国外对环保材料的需求增多，可降解塑料出口量增加;国内可降解塑料的生产工艺日趋成熟，成本逐渐降低下游可以接受范围。随着各方面条件的成熟配合，可降解塑料仍有较为广阔的发展前景。

In the long run, the domestic awareness of environmental protection has been strengthened, and the field of degradable plastics has been widened; The demand for environmental protection materials in foreign countries has increased, and the export volume of degradable plastics has increased; The production process of degradable plastics in China is becoming more and more mature, and the cost is gradually reduced to the downstream acceptable range. With the maturity of various conditions, degradable plastics still have a broad development prospect.

技术成本是可降解塑料市场竞争大问题。生物可降解材料相对于传统塑料产品能耗低，排放 CO2 少。在碳中和背景下，可降解材料为化工行业提供了一种全新的思路。但目前我国可降解塑料无论是 PLA 还是 PBAT 产 能均较小，一方面是过去成本较高，未受到重视。

Technology cost is a big problem in the market competition of degradable plastics. Compared with traditional plastic products, biodegradable materials consume less energy and emit less CO2. In the context of carbon neutralization, degradable materials provide a new idea for the chemical industry. However, at present, the production capacity of degradable plastics in China, whether PLA or PBAT, is small. On the one hand, the cost was high in the past and was not paid attention to.

另一方面是合成工艺较为复杂，政策资金支持不够。受到限塑令影响，可以看到未来我国可降解塑料市场空间巨大，多家生产企业均表示已经在建或者规划多条可降解塑料生产产能。我们认为，未来可降解塑料市场竞争短期是竞争建设速度，长期来看是是竞争成本优势、技术优势。谁能将可降解塑 料成本做到低，甚超过传统塑料，谁就会获得大的市场空间。

On the other hand, the synthesis process is complex and the policy and financial support are insufficient. Affected by the plastic restriction order, it can be seen that there is a huge market space for degradable plastics in China in the future. Many manufacturers have said that they are building or planning multiple degradable plastic production capacity. We believe that the future market competition of degradable plastics is the competitive construction speed in the short term, and the competitive cost advantage and technical advantage in the long term. Who can make the cost of degradable plastics low, even more than traditional plastics, will gain a large market space.

提到环保材料，纸是我们熟悉的一类材料，“以纸代塑”自然是优先想到的方案。无论从回收、可再生利用、可降解性上纸都是优的。但是，纸的生产需要大量的森林资源，大量的砍伐林木造成水土流失显然不符合我国国情。另一方面，在纸变成餐盒时，需要先把纸变成纸浆。但纸浆在生产时不仅会造成严重的水污染，而且生产成本也高，使得纸餐具也比较高。

When it comes to environmentally friendly materials, paper is a kind of material we are familiar with. Naturally, "paper instead of plastic" is the preferred solution. Paper is superior in terms of recycling, renewable utilization and degradability. However, the production of paper requires a large number of forest resources, and a large number of deforestation caused soil erosion is obviously not in line with China's national conditions. On the other hand, when paper becomes a lunch box, it needs to be turned into pulp first. However, the production of pulp will not only cause serious water pollution, but also the high production cost, which makes the price of paper tableware relatively high.

所谓可降解塑料就是在塑料的生产过程中加入添加剂，如光敏剂、淀粉等。像我司就在用玉米淀粉生产成一次性玉米淀粉餐具。这种方法制成的塑料制品废弃后，在大自然中暴露三个月后，将会由完整的形状分解成碎片，耗时较短。但这些碎片再继续降解的年限就比较长了。节省掩埋空间是这款餐盒的积极意义。

The so-called degradable plastic is to add additives such as photosensitizer and starch in the production process of plastic. For example, our company is using corn starch to produce disposable corn starch tableware. After being discarded and exposed in nature for three months, the plastic products made by this method will be decomposed into fragments from the complete shape, which takes less time. However, these fragments will continue to degrade for a long time. Saving buried space is the positive significance of this lunch box.
