这几种一次性餐盒的类型，你知道吗？下面一次性外卖打包盒厂家为您分析：

Do you know the types of disposable lunch boxes? The manufacturer of the disposable takeaway packaging box will analyze for you:

用塑料制成的一次性餐盒，主要有PP聚丙烯和PS聚苯乙烯两种，均无毒性无味无嗅，PP较柔软，一般PP使用温度是：-6度至+120度，所以特别适合盛装热饭热菜，可在微波炉里加热，甚或可在蒸气柜里蒸煮，改性的PP其使用温度可控制在 -18度至+110度，这种PP所制成的饭盒，除了可加热至100度使用外，更可放入冰箱冷藏使用。

Disposable lunch boxes made of plastic mainly come in two types: PP polypropylene and PS polystyrene, both of which are non-toxic, odorless, and soft. The general usage temperature of PP is -6 ° C to+120 ° C, making it particularly suitable for holding hot meals and dishes. It can be heated in a microwave or even steamed in a steam cabinet. The usage temperature of modified PP can be controlled between -18 ° C to+110 ° C. This type of PP can be used for lunch boxes, in addition to being heated to 100 ° C, It can also be refrigerated and used in the refrigerator.

PS较硬且透明，但易撕裂，PS在使用温度达75度时，开始变软，所以不适宜盛装热饭热菜，但PS的低温性能很好，是冰淇淋好的包装材料。

PS is hard and transparent, but easy to tear. When used at a temperature of 75 degrees, it begins to soften, making it unsuitable for holding hot rice and vegetables. However, PS has good low-temperature performance and is a good packaging material for ice cream.

有些饭盒为了降低成本，用PP做盒子，用PS做盒盖，好处是盖子透明且PS较硬，可以用较薄片材制成，降低成本，但这种设计消费者须明白两种材料的差异，切记不要把整盒饭连盖子一并放入微波炉中加热。

Some lunch boxes, in order to reduce costs, use PP as the box and PS as the lid. The advantage is that the lid is transparent and the PS is harder, which can be made of thinner sheets to reduce costs. However, consumers must understand the differences between the two materials in this design and remember not to heat the entire box of rice with the lid in the microwave.

纸板型

Cardboard type

纸板快餐盒是以300-350克的漂白硫酸盐木浆纸板为原料，通过类似钣加工的冲压成型工艺进行模切黏合或模切压制定型等工序制成，为防止其渗油或渗水要在其表面淋膜或施用化学助剂，在生产与使用过程中对人体是无毒无副作用的，但对于纸板的质量要求较高随之成本也提高。

Cardboard fast food boxes are made from 300-350 grams of bleached kraft wood pulp paperboard through stamping processes similar to sheet metal processing, such as die-cutting, bonding, or die-cutting, pressing, and shaping. To prevent oil or water leakage, a film should be coated on the surface or chemical additives should be applied. During production and use, they are non-toxic and have no side effects on the human body, but the high quality requirements for paperboard also increase the cost.

淀粉型

Starch type

以淀粉为原料的可食用型快餐盒，顾名思义它是以淀粉类植物为原料加入膳食纤维和其他可食用类助剂经搅拌捏合而成，它采用生物复配聚糖交联钙离子螯合等技术精制而成，由致密层、内防水层、胶网层和外防水层四部分构成。

An edible fast food box made from starch as the raw material, as the name suggests, is made by mixing and kneading starch plants with dietary fiber and other edible additives. It is refined using techniques such as biological complex glycan cross-linked calcium ion chelation, and is composed of four parts: a dense layer, an inner waterproof layer, a rubber mesh layer, and an outer waterproof layer.

纸浆模塑型

Pulp molded type

将木纸浆或芦苇蔗渣麦秸稻草等一年生草本植物纤维纸浆经碎浆和净化，加入适量无毒化学助剂，成型干燥整型定型切边消毒，制成产品的美观性并不高，同时也会增加废水的污染。

The pulp made from annual herbaceous plant fibers such as wood pulp or reed bagasse, wheat straw, and rice straw is crushed and purified, and an appropriate amount of non-toxic chemical additives are added to form, dry, shape, shape, shape, cut, and disinfect. The beauty of the product is not high, and it will also increase wastewater pollution.

植物纤维型

Plant fiber type

在环保优势上植物纤维餐盒具有明显的优势，它是以稻草稻谷壳甘蔗渣等提取的植物纤维作为原料加入成型剂黏合剂耐水剂等助剂，搅拌通过成型机成型加以干燥整型消毒等后期加工而成，这些农业的下脚料可成为工业原料有助于农业资源的综合利用。

The vegetable fiber lunch box has obvious advantages in environmental protection. It is made of plant fiber extracted from rice straw, rice husk, bagasse, etc. as raw materials, added with molding agent, Adhesive, water resistant agent and other additives, stirred by molding machine, dried, shaped, sterilized and other post-processing. These agricultural leftovers can be used as industrial raw materials to help the comprehensive utilization of agricultural resources.

可降解塑料餐盒

Degradable plastic lunch box

此类餐盒的制造原料是可降解塑料，所谓可降解塑料就是在塑料的生产过程中加入一定量的添加剂如光敏剂淀粉等原料，这样可降解塑料制品在使用完并废弃在大自然中暴露三个月后，可由完整的形状分解成碎片，因而至少在视觉上改善了环境，但这项技术大的缺陷是这些碎片不能继续降解，只不过是由大片变成小片塑料，不能从根本上胜任消除白色污染的任务。

The raw material for manufacturing such lunch boxes is degradable plastic. The so-called degradable plastic refers to the addition of a certain amount of additives such as photosensitizer starch in the production process of plastic. After being used and discarded in nature for three months, degradable plastic products can decompose into fragments from their complete shape, thus improving the environment visually at least. However, the major drawback of this technology is that these fragments cannot continue to degrade, It is just a transformation from large pieces to small pieces of plastic, which cannot fundamentally fulfill the task of eliminating white pollution.

生物全降解餐盒

Biodegradable lunch box

生物全降解餐盒是一种比较先进的环保产品。它以淀粉为主要原料，加入一年生长期植物纤维粉和特殊的添加剂，经过化学和物理方法处理制成生物全降解快餐盒，由于淀粉是一种可生物降解天然高分子，在微生物的作用下分解为葡萄糖，后分解为水和二氧化碳。

Biodegradable lunch boxes are a relatively advanced and environmentally friendly product. It uses starch as the main raw material, adding one-year plant fiber powder and special additives. After chemical and physical treatment, it is made into a fully biodegradable fast food box. As starch is a biodegradable natural polymer, it decomposes into glucose under the action of microorganisms, and then into water and carbon dioxide.

此外与其共混的材料也是全降解材料，因此可以说它对环境没有任何影响。生产原料淀粉的主要来源可以是玉米土豆红薯木薯等一年生长期植物。更多相关事项就来我们网站https://www.sdynbz.com咨询！

In addition, the material it blends with is also a fully biodegradable material, so it can be said that it has no impact on the environment. The main source of raw material starch for production can be plants such as corn, potatoes, sweet potatoes, and cassava that grow for one year.
