Disposable packaging boxes can be generally divided into plastic type, cardboard type, starch type, pulp molding type, plant fiber type, degradable plastic lunch box, biodegradable lunch box and other types. The following is an analysis for you one by one.

Disposable lunch boxes made of plastic are what we often call disposable PP packaging boxes and PS packaging boxes. Compared with other plastics, both of them are non-toxic, tasteless and odorless, so they are especially suitable for holding hot rice. Hot dishes, which can be heated in a microwave oven, is a commonly introduced one.

Cardboard fast food boxes are made of 300-350 grams of bleached sulphate wood pulp paperboard through a specific process. In the process of production and use, it is non-toxic and has no side effects to the human body. However, the quality requirements for cardboard are higher, and the cost is also increased.

Starch type, an edible fast food box with starch as the raw material. This is a brand new lunch box, which is not very popular at present.

Pulp molding type, this kind of wood raw materials is used to damage the trees, and the other is that it adds a lot of chemical substances, which is not environmentally friendly and is not recommended for everyone to buy.

Plant fiber lunch boxes, in terms of environmental protection advantages, plant fiber lunch boxes have obvious advantages. The use of agricultural scraps can become industrial raw materials and contribute to the comprehensive utilization of agricultural resources.

It uses starch as the main raw material, adds annual plant fiber powder and special additives, and is processed by chemical and physical methods to make a biodegradable fast food box. Therefore, the pollution problem of general degradable lunch boxes is solved.
