In recent years, disposable foam lunch box snack has been on the market turned green boxes, the original foam lunch boxes due to high temperature, and the production processes are environmentally damaging and highly-out, take the question of plastic boxes, paper boxes, wooden boxes, lunch boxes degradation ... etc. Among them, since the plastic has a low toxicity, high melting point, plasticity, easy and relatively low production cost, etc., it became the manufacture of disposable snack mainstream material. As PP plastic boxes, PP means polypropylene, it has excellent mechanical and thermal properties, especially for heating food packaging applications. And PS, polystyrene, rigid and brittle, non-toxic, tasteless, especially for frozen food packaging, such as cakes or salads.
Disposable fast-food type:
Plastic type cardboard type starch type moldable pulp plant fiber degradable plastic lunch box type Biodegradable lunch boxes made of plastic disposable lunch boxes mainly PP polypropylene and polystyrene PS two species of animals are non-toxic, tasteless and odorless, PP softer, general PP temperature -6 degrees to +120 degrees, it is particularly suitable to contain hot meals can be heated in the microwave, or even be cooked in a steam cabinet , modified PP can be controlled using temperature -18 degrees to +110 degrees, boxes made of PP this addition may be heated to 100 degrees to use, but also can be placed in the refrigerator to use. PS hard, and transparent, but easy to tear, PS when temperature reached 75 degrees begins to soften, so inappropriate dress hot meals, but a good low temperature performance PS is the best ice cream packaging material.
Cardboard snack is 300-350 grams paperboard bleached kraft pulp as raw material, through a similar process of sheet metal forming processes die bonding or die pressing, shaping and other processes made. To prevent oil leakage or seepage to the surface lamination or use of chemical additives. In the production and use of the process is non-toxic to humans, no side effects. But for higher quality cardboard, along with the cost increase.
Type starch, starch-based edible snack, as the name suggests, it is based on starchy plants as raw material, adding dietary fiber and other edible ingredient to a stirred kneaded together, it uses biological complex, cross-glycans Union, calcium chelation technology is refined, dense layer, a waterproof layer, network layer and the outer rubber layer is composed of four parts water.
Moldable pulp, wood pulp or the reed, bagasse, wheat straw, rice straw and other annual herb fiber pulp by pulping and purification, adding an appropriate amount of toxic chemical additives, molding, drying, integer, shaping, trimming, disinfection system to make. Product aesthetics is not high, but also increase pollution wastewater.
Vegetable fiber meal on the environmental advantages, vegetable fiber meal has obvious advantages, it is rice straw, rice hulls, bagasse extracted from plant fiber as raw material, molding, binders, water and the like additives stirred by molding machine, dried, shaping, disinfection and other post-processing. These scraps of agriculture can become industrial raw materials, contribute to the comprehensive utilization of agricultural resources.
Degradable plastic lunch boxes, lunch boxes manufacture of such raw material is biodegradable plastics, so-called biodegradable plastic is a certain amount of an additive in plastics production process, such as a photosensitizer, starch and other raw materials, so that degradable plastic products after use, discard in the nature and three months after exposure, can form a complete decomposition into pieces, so at least visually improve the environment. But the biggest flaw of this technique is that these fragments can not continue to degrade, but by a large piece of plastic into a small, incompetent eliminate white pollution tasks fundamentally.
Biological degradation of the whole meal is a more advanced environmentally friendly products.It starch as the main raw material, adding a year growing plant fiber powder and special additives, processed through chemical and physical methods made Biodegradable snack. Since starch is a biodegradable natural polymer, broken down into glucose under the action of microorganisms, and finally decomposed into water and carbon dioxide.
In addition, its blended material is also biodegradable material, so it can not have any impact on the environment.
The main source of raw materials production of starch, which can be a year of corn, potatoes, sweet potatoes, cassava and other growing plants.
Natural, biological degradation of the whole meal is also not perfect, for example, most of the raw materials of food crops, and there is mildew and other issues to be resolved.
