Environmental tableware is a good invention. For people, environmental protection tableware uses relatively simple materials, not too many chemical components, for people to use more safe and healthy. For the whole global environment, the use of environmental protection tableware has the characteristics of easy recovery and treatment, which will not cause great pollution to the environment. Therefore, environmental protection tableware still needs to be widely promoted. So, what materials are environmental protection tableware made of? Today, Xiaobian will take you to understand the environmental protection tableware materials.
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。
The disposable food boxes made of plastic are mainly PP polypropylene and PS polystyrene. They are non-toxic, tasteless and odorless, and PP is soft. Generally, PP is used at a temperature from - 6 ℃ to + 120 ℃. Therefore, it is especially suitable for holding hot rice and hot dishes. It can be heated in microwave oven or even steamed in a steam cabinet. The use temperature of modified PP can be controlled at & nbsp; nbsp; -From 18 ℃ to + 110 ℃, the lunch box made of PP can be heated to 100 ℃ for use, and can also be refrigerated in the refrigerator.
PS is hard, transparent and easy to tear. PS begins to soften when the temperature reaches 75 ℃, so it is not suitable for hot rice and hot dishes. However, PS has good low-temperature performance and is the best packaging material for ice cream.
In order to reduce the cost of some lunch boxes, PP is used as the box and PS is used as the cover. The advantage is that the cover is transparent, and the PS is hard. It can be made of thinner sheet material to reduce the cost. However, consumers must understand the difference between the two materials. Remember not to put the whole box of rice with the cover in the microwave oven.
Paperboard fast food box is made of 300-350g bleached kraft pulp paperboard by die-cutting bonding or die-cutting pressing and shaping process similar to sheet metal processing. In order to prevent its oil or water seepage, it is necessary to film or apply chemical additives on its surface. In the process of production and use, it is non-toxic and has no side effects on human body. But for paperboard quality requirements are higher, with the increase in cost.
The edible fast food box with starch as raw material, as the name implies, is made of starch plant as raw material, adding dietary fiber and other edible additives by mixing and kneading. It is refined by biological compounding, glycan crosslinking, calcium ion chelating and other technologies. It is composed of four parts: dense layer, inner waterproof layer, rubber mesh layer and outer waterproof layer
