一、塑料類打包盒?

1、 Plastic packaging box

塑料類打包盒是目前市場(chǎng)上使用最廣泛的類型之一，常見的材質(zhì)有聚丙烯（PP）、聚苯乙烯（PS）等。PP 材質(zhì)的打包盒具有良好的耐熱性，可在微波爐中加熱，且化學(xué)穩(wěn)定性較好，不易與食物發(fā)生反應(yīng)。其優(yōu)點(diǎn)是成本較低、透明度高、密封性強(qiáng)，能夠清晰看到盒內(nèi)食物，同時(shí)有效防止湯汁滲漏。但它也存在明顯的缺點(diǎn)，塑料難以自然降解，丟棄后會(huì)在環(huán)境中留存數(shù)百年，造成嚴(yán)重的白色污染。此外，一些劣質(zhì)塑料打包盒在高溫下可能會(huì)釋放出有害物質(zhì)，威脅人體健康。?

Plastic packaging boxes are currently one of the most widely used types in the market, with common materials such as polypropylene (PP) and polystyrene (PS). PP material packaging boxes have good heat resistance, can be heated in microwave ovens, and have good chemical stability, making them less likely to react with food. Its advantages are low cost, high transparency, strong sealing, and the ability to clearly see the food inside the box, while effectively preventing soup leakage. But it also has obvious drawbacks, plastic is difficult to naturally degrade, and after being discarded, it will remain in the environment for hundreds of years, causing serious white pollution. In addition, some inferior plastic packaging boxes may release harmful substances at high temperatures, posing a threat to human health. ?

PS 材質(zhì)的打包盒質(zhì)地硬且脆，常用于制作一次性碗、杯等。它價(jià)格低廉，成型容易，但不耐高溫，不能用于盛裝熱食，且同樣面臨難以降解的環(huán)保難題。?

The packaging box made of PS material is hard and brittle, commonly used for making disposable bowls, cups, etc. It is inexpensive and easy to shape, but it is not resistant to high temperatures and cannot be used to hold hot food. It also faces environmental challenges such as difficulty in degradation. ?

二、紙質(zhì)類打包盒?

2、 Paper packaging box

紙質(zhì)類打包盒以天然植物纖維為原料，如木漿、竹漿等。這類打包盒最大的優(yōu)勢(shì)在于環(huán)保性較好，可回收利用，且在自然環(huán)境中能夠較快降解。同時(shí)，其表面可以進(jìn)行精美的印刷，提升外賣的品牌形象。不過，紙質(zhì)打包盒也有局限性。由于紙張本身的特性，它的防水、防油性能相對(duì)較弱，盛裝含湯汁較多或油脂豐富的食物時(shí)，容易出現(xiàn)滲漏、變形的情況。而且，為了增強(qiáng)防水防油效果，部分紙質(zhì)打包盒會(huì)在表面添加化學(xué)涂層，若處理不當(dāng)，這些涂層中的化學(xué)物質(zhì)可能會(huì)遷移到食物中，帶來健康風(fēng)險(xiǎn)。?

Paper packaging boxes are made from natural plant fibers such as wood pulp, bamboo pulp, etc. The biggest advantage of this type of packaging box is its good environmental friendliness, recyclability, and ability to degrade quickly in natural environments. At the same time, its surface can be beautifully printed to enhance the brand image of food delivery. However, paper packaging boxes also have limitations. Due to the inherent characteristics of paper, its waterproof and oil resistant properties are relatively weak. When storing food with a lot of soup or rich oil, it is prone to leakage and deformation. Moreover, in order to enhance the waterproof and oil resistant effect, some paper packaging boxes will have chemical coatings added to the surface. If not handled properly, the chemicals in these coatings may migrate to food, posing health risks. ?

三、生物可降解類打包盒?

3、 Biodegradable packaging box

生物可降解類打包盒是近年來興起的新型環(huán)保包裝材料，主要由玉米淀粉、聚乳酸（PLA）等可生物降解材料制成。它們?cè)谧匀画h(huán)境中，可通過微生物的作用分解為二氧化碳和水，不會(huì)對(duì)環(huán)境造成長(zhǎng)期污染。這類打包盒在性能上與傳統(tǒng)塑料打包盒相似，具有良好的密封性、耐熱性和機(jī)械強(qiáng)度，能夠滿足外賣包裝的基本需求。然而，目前生物可降解類打包盒也面臨一些問題，一方面其生產(chǎn)成本相對(duì)較高，導(dǎo)致售價(jià)較貴，限制了在市場(chǎng)上的廣泛推廣；另一方面，生物可降解材料的降解需要特定的環(huán)境條件，如合適的溫度、濕度和微生物環(huán)境，若處理不當(dāng)，在普通垃圾填埋場(chǎng)中也難以實(shí)現(xiàn)快速降解。?

Biodegradable packaging boxes are a new type of environmentally friendly packaging material that has emerged in recent years, mainly made of biodegradable materials such as corn starch and polylactic acid (PLA). They can be decomposed into carbon dioxide and water through the action of microorganisms in the natural environment, without causing long-term pollution to the environment. This type of packaging box is similar in performance to traditional plastic packaging boxes, with good sealing, heat resistance, and mechanical strength, which can meet the basic needs of takeaway packaging. However, currently biodegradable packaging boxes also face some problems. On the one hand, their production costs are relatively high, resulting in expensive prices and limiting their widespread promotion in the market; On the other hand, the degradation of biodegradable materials requires specific environmental conditions, such as appropriate temperature, humidity, and microbial environment. If not handled properly, it is also difficult to achieve rapid degradation in ordinary landfills. ?
