Analysis of the advantages of disposable biodegradable tableware of pulp molded tableware.

Since the first use of disposable tableware in China in 1984, foam tableware with polystyrene (eps) as the main raw material has rapidly spread to all corners of China and entered the daily life of passers-by, forming a huge consumer market. According to statistics, China consumes about 10 billion kinds of fast food utensils every year, most of which are disposable foam tableware, with an annual growth rate of 25%.

Due to the non-degradable and difficult recycling of polystyrene, it brings great inconvenience to the disposal.

After several years of efforts, the production process, technology and bamboo teaspoon equipment of pulp molding disposable tableware in China have developed rapidly. In terms of variety, a variety of tableware required for hot and cold catering (such as fast food boxes, various sizes of wai, plates, trays and bowls) have been developed; various food plates, vegetable and fruit plates used in supermarkets, etc. In terms of performance, it has been fully able to meet Chinese eating habits and can hold hot soup, oil and water without leakage.

Since then, the pulp molding industry has been growing and expanding rapidly in China with its environmentally friendly vitality, and by the end of 1990s, it started to scale up and industrialize. Now, pulp molding comes from nature's environmentally friendly containers!

Pulp molded fully degradable tableware.

Annual herbaceous plant fiber pulp, such as wheat straw, sugar cane, reeds, straw, etc., is shredded, injected (or sucked and fished), molded, shaped (or shaped), trimmed, selected, sterilized, and packaged. The raw materials used are recycled and renewable, and the physical pulp making method has no black water and produces waste water.

Advantages of pulp molded tableware:

(1) The raw materials are waste pulp or renewable wheat, reeds, straw, bamboo, sugar cane, palm and other straw fibers, which are widely available and inexpensive and do not use wood.

(2)No waste water and discharge in the production process. Natural environmental protection container.

(3)The product is waterproof and oil-proof.

(4)The use process can be, frozen, microwave heating, 220 degrees baking.

(5) The product can be completely degraded in the natural state within 45-90 days and can be composted at home. The main component after degradation is organic matter, which will not produce any waste residue and pollution.

(6) As a packaging container, it has the characteristics of buffering, pressure resistance and shock, which can effectively protect the packaging products.

(7) Packaging electronic products will not generate static electricity.

Corn starch disposable tableware.

The main components consist of carrier resin, corn starch, coupling infiltrant phase solvent and other low molecules. Edible fast tableware with starch as raw material. It is made of starchy plant as raw material and stirred and kneaded with edible additives such as dietary fiber. It is refined by biocomposite, polysaccharide cross-linking, calcium ion chelation and other technologies. It consists of four parts: dense layer, inner waterproof layer, rubber mesh layer and outer waterproof layer.

Most of the corn starch tableware circulating in the domestic market is partially degraded lunch boxes, not up to the level of full degradation.

Third, cardboard tableware.

Cardboard fast tableware is made of 300-350 grams of bleached sulfate wood pulp cardboard, made by a stamping and forming process similar to sheet metal processing.

In order to prevent it from seeping oil or water, it should be coated on its surface or apply chemical additives. It is non-toxic to human body and has no side effects during the production and use. However, the quality of the cardboard is required to be high and the cost will increase.
