Paper lunch box manufacturer on the selection standard of lunch box
Biodegradable plastic 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, but by the shape of the complete decomposition into pieces, so at least on the vision to improve the environment. But the biggest drawback of the technology is that the pieces don't go on to degrade, just turn from big pieces to small pieces of plastic, and aren't fundamentally competent for the task of eliminating white pollution.
Biodegradable lunch box is an advanced environmental protection product. It takes starch as the main raw material, adds the annual long term plant fiber powder and the special additive, after the chemical and physical treatment to make the biodegradable fast food box. Because starch is a biodegradable natural polymer, it is decomposed into glucose by microorganisms and finally into water and carbon dioxide. In addition, the material blended with it is also completely degraded, so it can be said that it has no impact on the environment. The main source of raw starch production can be corn, potato, sweet potato, cassava and other annual long-term plants. Naturally, biodegradable lunch boxes are not perfect either. For example, most of the raw materials for production are grain crops, and mildew proofing and other problems remain to be solved.

Disposable fast food box classification, cardboard fast food box is made of 300-350 grams of bleached sulfate wood pulp board as raw material, through a stamping forming process similar to the plate processing, die cutting bonding or die cutting pressing, shaping and other processes. In order to prevent its oil or water seepage, to its surface film or apply chemical additives. In the process of production and use of the human body is non-toxic, no side effects.
