The plastic type
Disposable meal boxes made of plastic are mainly PP polypropylene and PS polystyrene two kinds, are non-toxic, tasteless and odorless, PP is relatively soft, generally PP temperature is -6 degrees to +120 degrees, so it is especially suitable for hot rice hot dishes, can be heated in the microwave oven, or even can be steamed in the gas cabinet, The use temperature of modified PP can be controlled from -18 degrees to +110 degrees. The lunch box made of this PP can be heated to 100 degrees and refrigerated.
Board type
The PAPERBOARD SNACK BOX IS MADE OF 300-350 GRAMS OF BLEACHED KRAFT WOOD PULP PAPERBOARD AS RAW MATERIAL, DIE-cutting BONDING OR DIE-cutting pressing, SHAPING and other processes by stamping molding process similar to plate processing. In order to prevent oil seepage or water seepage, it is necessary to spray film on its surface or apply chemical additives. In the process of production and use of the human body is non-toxic, no side effects. However, the quality of cardboard is higher, and the cost is also increased.
Starch type
Using starch as raw material of edible snack box, as the name suggests, it was based on the starch plants as raw material, adding dietary fiber and other edible processed by mixing kneading, it USES of biological compound, chitosan crosslinked, calcium ion chelating technologies such as refined but become, using temperature is 10 degrees to + 120 degrees, so especially suitable for holding a hot meal hot food, it can be heated in the microwave, Can also be put into the refrigerator cold use.
Paper pulp molding
Wood pulp or annual herbaceous cellulose pulp such as reed, BAGasse, wheat straw and straw is made by crushing pulp and purification, adding appropriate amount of non-toxic chemical additives, forming, drying, shaping, shaping, cutting and disinfection. The beauty of the product is not high, and it will increase the pollution of waste water.
Plant fiber type
In terms of environmental protection, plant fiber lunchbox has obvious advantages. It is made of rice straw, rice husk, bagasse and other plant fibers extracted as raw materials, adding molding agents, adhesives, water-resistant agents and other additives, stirring through molding machines, drying, shaping, disinfection and other post-processing. These agricultural wastes can become industrial raw materials and contribute to the comprehensive utilization of agricultural resources.
Biodegradable plastic meal boxes
These boxes are biodegradable plastic raw materials, the so-called biodegradable plastic is in the production of plastic to join a certain amount of additives, such as photosensitizer, raw materials such as starch, such, biodegradable plastic products after use, and scrap in nature after three months, can be made of the shape of the complete decomposition into pieces, and thus to improve the environment.
