Disposable lunch box  
E-mail:  *@********************osable snack box has been turned from the foam lunch box to the green lunch box. The original foam lunch box was rejected because of its high temperature resistance and damage to the environment during the production process. The plastic lunch boxes, paper lunch boxes, wooden lunch boxes, degrading lunch boxes and so on were selected. Among them, plastic has the characteristics of low toxicity, high melting point, strong plasticity, simple production and low relative cost, so it has become the main material for making disposable fast food box.

PP polypropylene, with mechanical and thermal properties, is suitable for food packaging. Lunch boxes are divided into environmental protection lunch boxes, mainly including plastic, paper, starch and rare metals.
Plastic type



The disposable lunch box made of plastic mainly includes PP polypropylene and PS polystyrene, which are non-toxic, tasteless and odorless. PP is relatively soft. Generally, the service temperature of PP is - 6 ℃ to + **0 ℃, so it is especially suitable for holding hot meals and hot dishes. It can be heated in microwave oven, or even boiled in steam cabinet. The service temperature of modified PP can be controlled within -From *8 ° C to + **0 ° C, the lunch box made of this PP can be used not only by heating to **0 ° C, but also by refrigerating.

PS is hard and transparent, but easy to tear. PS starts to soften when the temperature reaches *5 ℃, so it is not suitable for hot meals and hot dishes. But PS has a good low temperature performance and is the best packaging material for ice cream.

In order to reduce the cost, some lunch box factories use PP as the box and PS as the box cover. The advantage is that the cover is transparent and PS is relatively hard, which can be made of thin sheet materials to reduce the cost. However, consumers must understand the difference between the two materials in this design, and remember not to put the whole lunch box with the cover into the microwave oven for heating.

Paperboard type

Cardboard lunch box

Cardboard lunch box

The paper board fast food box is made of ******0g bleached kraft wood pulp paper board as raw material through die-cutting adhesion, die-cutting pressing, shaping and other processes similar to sheet metal processing. In order to prevent its oil or water seepage, it is necessary to film or apply chemical AIDS on its surface. In the process of production and use, it is non-toxic and has no side effects on human body. However, the quality of paperboard is required to be high, and the cost is also increased.
