Cardboard type
Cardboard snack box is made of 300g - 350g bleached kraft wood pulp paperboard through die cutting and bonding, die cutting and pressing, shaping and other processes similar to sheet metal processing. In order to prevent oil or water seepage, it is necessary to coat its surface or apply chemical additives. It is non-toxic and has no side effects on human body during production and use. However, the quality of paperboard is required to be high, and the cost is also increased.
Starch type
As the name suggests, the edible fast food box made of starch is made of starch plants, added with dietary fiber and other edible additives, stirred and kneaded. It is refined by biological compounding, glycan cross-linking, calcium ion chelation and other technologies. The temperature of use is - 10 ℃ to+120 ℃, so it is especially suitable for holding hot rice and vegetables. It can be heated in a microwave oven, and can be put into a refrigerator for refrigeration.
Pulp molded
Its production process is completed by processes such as pulping, adsorption molding, drying and shaping, which is harmless to the environment; It can be recycled; The volume is smaller than that of foam plastic, which can be overlapped, and the transportation is convenient. Pulp molding, in addition to serving as lunch boxes and tableware, is more used as industrial cushioning packaging, which has developed rapidly.
Plant fiber type
In terms of environmental protection advantages, the vegetable fiber lunch box has obvious advantages. It is made of plant fibers extracted from rice straw, rice husk, bagasse, etc. as raw materials, added with molding agents, adhesives, water resistant agents and other additives, and then molded by a molding machine, dried, reshaped, disinfected and processed later. These agricultural wastes can be used as industrial raw materials and contribute to the comprehensive utilization of agricultural resources.
Degradable plastic lunch box
The raw material for making this kind of lunch box is degradable plastic. The so-called degradable plastic is that a certain amount of additives, such as photosensitizer, starch and other raw materials, are added in the production process of plastic. In this way, the degradable plastic products can be decomposed into fragments from the complete shape after being used and discarded in nature for three months, thus improving the environment.
Biodegradable lunch box
Biodegradable lunch box is an advanced environmental protection product. It takes starch as the main raw material, adds one-year growth period plant fiber powder and special additives, and is processed by chemical and physical methods to make a biodegradable snack box. As starch is a biodegradable natural polymer, it is decomposed into glucose under the action of microorganisms, and finally into water and carbon dioxide.
Today, due to the rapid development of the Internet, the takeout industry has also grown rapidly. More and more people choose to use Internet point takeout, and more and more people use disposable biodegradable lunch boxes. Therefore, when choosing lunch boxes, biodegradable lunch boxes are chosen to avoid environmental pollution.
