一次性外卖打包盒的七种分类材料
来源:www.sdynbz.com 发布时间:2022-08-16 浏览次数:122
外卖常用一次性外卖打包盒来给饭菜保温,一次性保温盒有塑料型、纸板型、淀粉型、纸浆模塑型等七种,需要注意的是有的材质可以放进微波炉里加热,有的不能。下面来展开讲讲吧。
Take out food is usually packaged in disposable take out boxes to keep food warm. There are seven kinds of disposable heat preservation boxes: plastic, cardboard, starch and pulp molding. It should be noted that some materials can be put into the microwave oven for heating, while others cannot. Let's talk about it.
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,均无毒牲,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 include PP polypropylene and PS polystyrene, which are non-toxic, tasteless and odorless. PP is soft. Generally, the use temperature of PP is - 6 ° C to + 120 ° C, so it is particularly suitable for holding hot meals and hot dishes. It can be heated in a microwave oven or even cooked in a steam cabinet. The use temperature of modified PP can be controlled between - 18 ° C and + 110 ° C. In addition to heating to 100 ° C, It can also be put into the refrigerator for refrigeration.
有些饭盒工厂为了降低成本,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。
In order to reduce the cost, some lunch box factories use PP as the box and PS as the lid. The advantage is that the lid is transparent and the PS is hard. It can be made of thinner sheets to reduce the cost. However, consumers of this design must understand the difference between the two materials and remember not to put the whole lunch box and the lid into the microwave oven for heating.
纸板型
Paperboard 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 of 300-350g bleached kraft wood pulp cardboard as raw material, through die-cutting bonding or die-cutting pressing, shaping and other processes through a stamping process similar to sheet metal processing. In order to prevent oil or water seepage, film or apply chemical additives on the surface. In the process of production and use, it is non-toxic and has no side effects. However, the quality of paperboard is required to be high, and the cost is also increased.
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,使用温度是-10度至+120度,所以特别适合盛装热饭热菜,可在微波炉里加热,更可放入冰箱冷藏使用。
The edible fast-food box with starch as raw material, as the name implies, is made of starch plants as raw materials, dietary fiber and other edible additives through mixing and kneading. It is refined by biological compounding, glycan crosslinking, calcium ion chelation and other technologies. The use temperature is - 10 ° C to + 120 ° C, so it is especially suitable for holding hot meals and hot dishes. It can be heated in a microwave oven and can be put into a refrigerator for refrigeration.
纸浆模塑型
Pulp molding
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。
Wood pulp or annual herb fiber pulp such as reed, bagasse, wheat straw and rice straw are pulped and purified, and an appropriate amount of non-toxic chemical additives are added to form, dry, shape, shape, cut and disinfect. The beauty of the product is not high, and it will also increase the pollution of waste water.

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、整形、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。
In terms of environmental protection, the plant fiber lunch box has obvious advantages. It is made of the plant fiber extracted from rice straw, rice husk and sugarcane bagasse as raw materials, mixed with molding agent, adhesive, water-resistant agent and other additives, formed by the molding machine, and then dried, shaped and disinfected. These agricultural leftovers can become industrial raw materials and contribute to 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,因而改善了环境。
The raw material of this kind of lunch box is degradable plastic. The so-called degradable plastic is to add a certain amount of additives, such as photosensitizer, starch and other raw materials in the production process of plastic. In this way, the degradable plastic products can be decomposed into fragments from their complete shape after being used and discarded in the nature for three months, thus improving the environment.
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 box is an advanced environmental protection product. It takes 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 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。自然,生物全降解生产原料大部分是粮食作物,对环境无任何污染可完全代替泡沫餐盒。更多相关内容就来我们网站咨询了解吧。
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 raw material starch can be corn, potato, sweet potato, cassava and other one-year growing plants. Naturally, most of the biodegradable raw materials are food crops, which have no pollution to the environment and can completely replace the foam lunch box.
