The advantage analysis of paper pulp molding tableware for disposable degradable tableware
Disposable tableware since 1984 in China for the first time, a polystyrene (eps) as the main raw material of the foam plastic tableware rapidly spread in every corner of the country, into the daily life of people, forming a huge consumer market. According to statistics, China consumes about 10 billion fast food utensils every year, most of which are disposable foamed plastic tableware, and the annual growth rate is 25 percent.
Because polystyrene is not degradable, it is difficult to recycle and so on, which brings great inconvenience to the processing work. After years of hard work, the production technology, technology and equipment for disposable pulp molding tools and food and beverage have been rapidly developed in our country. All kinds of tableware needed for cold and hot food and beverage (such as fast food box, plates, plates, bowls in various sizes) have been developed; A variety of food plates, vegetable plates, fruit plates, etc. used in supermarkets. In the performance, has been able to fully meet the Chinese eating habits, can be dressed in hot soup oil and water, no leakage requirements.
Since then, the pulp molding industry with its vitality of environmental protection in the land of China rapid growth and expansion, to the late 1990s, began to scale, industrialization. At present, the paper pulp molding from nature's environmentally friendly containers!
A, pulp molding degradation tableware
With wheat straw, sugarcane, reed, straw and other annual herbaceous plant fiber pulp through pulp crushing, grouting (or sucking, dredging), shaping, shaping (or shaping), cutting, selection, disinfection, packaging, etc. The raw materials used are recycled and renewable, and no black water or waste water is produced by physical pulping method.
Advantages of pulp molding tableware:
(1) The raw material is waste pulp or renewable wheat, reed, straw, bamboo, sugar cane, palm and other straw fibers. The source is wide, the price is low, and no wood is used.
(2) No waste water is generated or discharged in the production process. Eco-friendly containers from nature
(3) The product is waterproof and oil proof
(4) In the process of use, can be frozen, frozen, microwave oven heating, can bake 220 degrees
(5) The product can be fully degraded in the natural state within 45-90 days, and can be composted at home. After degradation, the main component is organic matter, which will not produce any garbage residue and pollution.
(6) As a packaging container, it has the characteristics of buffering, compressive resistance and shock-proof, which can effectively protect the packaged products.
(7) Packaging electronic products will not produce static electricity
Two, corn starch disposable tableware
The main component is carrier resin. Corn starch. Coupling agent infiltrating agent phase solvent and other low molecular composition. Starch-based edible fast food tableware. It is made of starch plants as raw materials, adding dietary fiber and other edible additives by mixing and kneading. It is refined by biological compounding, glycan crosslinking, calcium ion chelating and other technologies. It is composed of four parts: dense layer, inner waterproof layer, rubber mesh layer and outer waterproof layer. Most of the corn starch tableware in circulation in the domestic market are partially degraded meal boxes, which cannot reach the level of full degradation.
Three, cardboard tableware
Board fast tableware is made of 300-350g bleached sulfate wood pulp board as raw material, die-cutting bonding, die-cutting pressing, shaping and other processes through stamping molding process similar to plate processing.
In order to prevent oil or water seepage, it is necessary to spray film on its surface or apply chemical additives. In the process of production and use is non-toxic to human body, no side effects. But for the quality of cardboard requirements are higher, the cost is also increased.
