塑料型

　　Plastic type

　　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 food containers made of plastic mainly include PP polypropylene and PS polystyrene, both of which are non-toxic, odorless, and tasteless. PP is relatively soft, and the general temperature range for PP is -6 ° C to+120 ° C, making it particularly suitable for holding hot rice and vegetables. It can be heated in a microwave or even steamed in a steam oven. The modified PP can be controlled to a temperature range of -18 ° C to+110 ° C. These lunch boxes made of PP can not only be heated to 100 ° C for use, but also stored in a refrigerator for refrigeration.

　　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，是冰淇淋最好的包装材料。

　　PS is relatively hard and transparent, but it is easy to tear. When used at a temperature of 75 degrees, PS begins to soften, so it is not suitable for holding hot meals and dishes. However, PS has good low-temperature performance and is the best 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，但这种设计消费者必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 use PP for the box and PS for the lid in order to reduce costs. The advantage is that the lid is transparent and PS is harder, which can be made of thinner sheets to reduce costs. However, consumers must understand the difference between the two materials in this design and remember not to heat the entire box of lunch with the lid in a microwave oven.

　　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。

　　The cardboard fast food box is made from 300-350 grams of bleached kraft pulp cardboard as raw material, which is processed through stamping and forming processes similar to sheet metal processing, such as die-cutting bonding or die-cutting compression shaping. To prevent oil or water leakage, a film or chemical additives should be applied on its surface. It is non-toxic and has no side effects on the human body during production and use, but the quality requirements for cardboard are high, and the cost also increases.

　　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 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 compound polysaccharide cross-linking calcium ion chelation, and consists 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 molding 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 fiber pulp of annual herbaceous plants such as wood pulp, reed, sugarcane 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, cut and disinfect the edges. The beauty of the resulting product is not high, and it also increases the pollution of wastewater.

　　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。

　　Plant fiber meal boxes have obvious advantages in environmental protection. They are made from plant fibers extracted from rice straw, rice husks, sugarcane bagasse, and other materials, and added with molding agents, adhesives, water-resistant agents, and other additives. They are mixed and molded by a molding machine, dried, shaped, disinfected, and processed later. These agricultural waste materials can become industrial raw materials, which helps to comprehensively utilize 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，但这项技术最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 manufacturing material of this type of food box is biodegradable plastic, which refers to the addition of a certain amount of additives such as photosensitizer starch during the production process of plastic. After being used and exposed to nature for three months, biodegradable plastic products can break down from their complete shape into fragments, at least visually improving the environment. However, the biggest drawback of this technology is that these fragments cannot continue to degrade, only turning from large pieces into small pieces of plastic, which cannot fundamentally fulfill the task of eliminating white pollution.

　　生物全降解餐盒

　　Biodegradable food 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，最后分解为水和二氧化碳。

　　Biodegradable food containers are a relatively advanced and environmentally friendly product. It uses starch as the main raw material, adds one-year growth period plant fiber powder and special additives, and is processed by chemical and physical methods to make a biodegradable fast food box. As starch is a biodegradable natural polymer, it is decomposed into glucose under the action of microorganisms, and finally 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。

　　In addition, the material blended with it is also a fully degradable material, so it can be said that it has no impact on the environment. The main source of starch production raw materials can be one-year growing plants such as corn, potatoes, sweet potatoes, cassava, etc.

　　自然生物全降解餐盒也并不是十全十美，例如生产原料大部分是粮食作物且有防霉变等问题尚待解决。

　　Natural biodegradable meal boxes are not perfect, for example, most of the production materials are grain crops and there are problems such as mold resistance that need to be solved.
