All companies in an industry compete with the industries that produce alternative products. The alternatives set a pricing ceiling for the profits that companies can make in the industry, thereby limiting the potential benefits of an industry. The more attractive the price performance options offered by alternatives, the lower the ceiling on industry profits.
The environmentally friendly pulp tableware includes Biodegradable Paper Round Bowl. The substitutes are divided into five categories: foamed plastics, photodegradable plastics, plant fibers, starch blends, and cardboard. These five categories of products together with pulp tableware constitute the disposable tableware market.
Biodegradable Paper Round Bowl
1. Foamed plastic (EPS)
This is the earliest disposable tableware. It is produced while being convenient to eat, and has produced a series of problems, which are mainly manifested in the following: when it is used to hold hot soup, toxic substances such as bisphenols contained in them are precipitated and immersed in food to the human body. Cause damage, especially in the production of foam tableware raw materials, if the concentration of harmful substances exceeds the standard, the poison will be greater, causing great harm to the human body; the time for its degradation in nature needs one to two hundred years, and abandoned tableware enters After the soil, not only does it not rot for a long time, but also affects the permeability of the soil, thereby destroying the soil; the burning of discarded tableware will release more than ten kinds of chemically toxic gases, which will seriously pollute the atmosphere. Therefore, with the rapid development of the fast food industry, a global environmental problem "white pollution" has arisen. However, due to its good usability and low price, the foam snack box does not have the problem of oil leakage and water leakage, and still floods the market. It is currently the largest amount in the market, accounting for more than 60% of the entire market, but it withdrew once. The sex tableware market is inevitable, just a matter of time.
2. Photodegradable plastics
This kind of tableware is mainly added some additives (such as starch, biodegradation agent, etc.) during the production of plastic products. Adding starch to the degradable plastic is called biodegradable plastic, adding photosensitizer is called photodegradable plastic, and adding starch at the same time. And photosensitizers are called double-degradable plastics. Its various performance indicators are good, but biodegradable plastics cannot completely degrade the molecular state, they can only be degraded into small fragments, and they also pollute the environment. The photosensitizers in photodegradable plastics and double-degradable plastics have different degrees of toxicity.
3. Plant fiber
It is mainly made of bagasse, straw, straw and other raw materials, such as Biodegradable Sugarcane Fast Food Package, which is made through processes such as pulverization and ingredient pressure molding. It fully meets environmental protection requirements, but the biodegradation process is extremely slow and costly.
4. Starch blends
This tableware is made of starch plants such as corn, potatoes, etc., and its biodegradability is unmatched by other synthetic materials. It is also called a full biodegradable material. However, due to production technical problems, the product is waterproof. The performance is difficult to solve, and the production cost is relatively high, so it is less used in the market and is also in the research and development stage.
The tableware is non-toxic, harmless, non-polluting and recyclable. But its technology is cardboard roll compression shearing, the product form is single, and there are problems with softness, water resistance and oil resistance in quality. And its raw material is cardboard, which requires wood fiber materials that meet various physical and chemical requirements for waterproofing, oil-proofing, and grease-proofing. Cutting a large amount of wood will cause ecological damage. Because of its simple production process and low price, it is widely used in paper cups, paper buckets and paper trays, but with the protection of forest resources, its price is getting higher and higher.
Pulp molded packaging products are in line with plastic packaging alternatives. Unbleached Paper Pulp Cup suppliers continue to work hard to carry forward the concept of environmental protection.
