在餐盒使用量巨大的餐飲行業(yè)，各種類型的可降解餐盒可謂是百花爭(zhēng)艷。一款以植物纖維為主的環(huán)保餐盒卻悄然脫穎而出，俏銷市場(chǎng)。那么玉米淀粉餐盒和其他的植物纖維餐盒是否一樣呢？

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?

從長(zhǎng)期來(lái)看，國(guó)內(nèi)環(huán)保意識(shí)增強(qiáng)，可降解塑料使用的領(lǐng)域拓寬;國(guó)外對(duì)環(huán)保材料的需求增多，可降解塑料出口量增加;國(guó)內(nèi)可降解塑料的生產(chǎn)工藝日趨成熟，成本逐漸降低下游可以接受范圍。隨著各方面條件的成熟配合，可降解塑料仍有較為廣闊的發(fā)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.

技術(shù)成本是可降解塑料市場(chǎng)競(jìng)爭(zhēng)大問(wèn)題。生物可降解材料相對(duì)于傳統(tǒng)塑料產(chǎn)品能耗低，排放 CO2 少。在碳中和背景下，可降解材料為化工行業(yè)提供了一種全新的思路。但目前我國(guó)可降解塑料無(wú)論是 PLA 還是 PBAT 產(chǎn) 能均較小，一方面是過(guò)去成本較高，未受到重視。

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.

另一方面是合成工藝較為復(fù)雜，政策資金支持不夠。受到限塑令影響，可以看到未來(lái)我國(guó)可降解塑料市場(chǎng)空間巨大，多家生產(chǎn)企業(yè)均表示已經(jīng)在建或者規(guī)劃多條可降解塑料生產(chǎn)產(chǎn)能。我們認(rèn)為，未來(lái)可降解塑料市場(chǎng)競(jìng)爭(zhēng)短期是競(jìng)爭(zhēng)建設(shè)速度，長(zhǎng)期來(lái)看是是競(jìng)爭(zhēng)成本優(yōu)勢(shì)、技術(shù)優(yōu)勢(shì)。誰(shuí)能將可降解塑 料成本做到低，甚超過(guò)傳統(tǒng)塑料，誰(shuí)就會(huì)獲得大的市場(chǎng)空間。

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.

提到環(huán)保材料，紙是我們熟悉的一類材料，“以紙代塑”自然是優(yōu)先想到的方案。無(wú)論從回收、可再生利用、可降解性上紙都是優(yōu)的。但是，紙的生產(chǎn)需要大量的森林資源，大量的砍伐林木造成水土流失顯然不符合我國(guó)國(guó)情。另一方面，在紙變成餐盒時(shí)，需要先把紙變成紙漿。但紙漿在生產(chǎn)時(shí)不僅會(huì)造成嚴(yán)重的水污染，而且生產(chǎn)成本也高，使得紙餐具也比較高。

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.

所謂可降解塑料就是在塑料的生產(chǎn)過(guò)程中加入添加劑，如光敏劑、淀粉等。像我司就在用玉米淀粉生產(chǎn)成一次性玉米淀粉餐具。這種方法制成的塑料制品廢棄后，在大自然中暴露三個(gè)月后，將會(huì)由完整的形狀分解成碎片，耗時(shí)較短。但這些碎片再繼續(xù)降解的年限就比較長(zhǎng)了。節(jié)省掩埋空間是這款餐盒的積極意義。

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.
