Biodegradable blister disposable lunch boxes. The raw materials for this kind of disposable lunch boxes are degradable plastics. The so-called degradable blister is the addition of a certain amount of additives, such as photosensitizers, starch and other raw materials during the production of plastics. , The degradable blister disposable lunch box can be broken down into pieces from the complete shape after being used and discarded in the nature for three months, thus at least visually improving the environment. But the biggest drawback of this technology is that these fragments cannot continue to be degraded. They only turn from large pieces into small pieces of plastic, and are not fundamentally competent for the task of eliminating white pollution.
Biodegradable disposable lunch box is a relatively advanced environmentally friendly product. 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 disposable lunch box. Because starch is a biodegradable natural polymer, it is decomposed into glucose under the action of microorganisms, and finally decomposed into water and carbon dioxide.
Starch type, an edible quick disposable lunch box with starch as raw material. As the name suggests, it is made of starchy plants as raw materials, adding dietary fiber and other edible additives through mixing and kneading. Seventh, it adopts biological compounding, It is refined by glycan cross-linking, calcium ion chelation and other technologies. It consists of four parts: a dense layer, an inner waterproof layer, a rubber mesh layer and an outer waterproof layer.
Plant fiber disposable lunch boxes, in terms of environmental protection advantages, plant fiber disposable lunch boxes have obvious advantages. It uses plant fibers extracted from rice straw, rice hulls, bagasse, etc. as raw materials, and adds forming agents, binders, and water-resistant agents. And other additives are stirred and formed by a forming machine, and then processed by post-processing such as drying, shaping, and disinfection. These agricultural leftovers can become industrial raw materials and contribute to the comprehensive utilization of agricultural resources.
The last one is the disposable lunch box type of pulp molding. The pulp of wood pulp or annual herb fiber such as reed, bagasse, wheat straw, straw, etc. is pulverized and purified, and an appropriate amount of non-toxic chemical additives are added to form, dry, shape, and shape. Shaped, trimmed, and sterilized. The aesthetics of the product is not high, and it will increase the pollution of wastewater.
