When buying eggs, it is often seen that an egg paper tray is used for protection when packaging eggs. The egg paper tray is a pulp molded packaging product. Its raw materials are made of waste materials such as bagasse, reed, bamboo, and straw. The pulp is an excellent substitute for traditional wood paper products. It is harmless to the environment, can be degraded naturally, and can be recycled and reused.
Pulp molded paper tray is made of plant fiber pulp or waste paper products that can be fully recycled and recycled as the basic material. It is made by unique technology and is widely used in food (medicine) storage, electrical packaging, planting and nursery. , Medical utensils, handicraft blanks and fragile product liner packaging and other fields of pollution-free technology-based green environmental protection paper trays.
2. With the development of industry, a large amount of fluorine-containing substances have risen into the atmosphere, causing extensive destruction of the ozone layer on which humans depend. Several thousand kilometers of ozone layer holes have been formed in the Antarctic and Arctic, causing damage to the earth’s ecological environment. To this end, the United Nations Environmental Protection Agency convened a world-wide environmental conference. In 1998, the "Vienna Convention for the Protection of the Ozone Layer" and the "Montreal Protocol on Substances that Deplete the Ozone Layer" were passed, clearly stipulating that countries in the world It is necessary to gradually reduce the use until the fluorine-containing substances that destroy the ozone layer are prohibited from entering the atmosphere.
3. In recent years, plastic products, one of the three major packaging materials, especially expanded polystyrene (EPS) products, have become increasingly serious in many disadvantages, and have become a "white pollution" that everyone hates. The waste disposal of these polystyrene foam packaging has brought serious pollution to the environment. Combustion destroys the earth's atmospheric ozone layer; piles cannot be corroded, resulting in damage to the geological structure. These foam plastic product wastes have caused great damage to the earth's environment. Switching to biodegradable environmentally friendly packaging materials, eliminating "white pollution", and improving people's living environment have become international and domestic express requirements.
4. Tableware products and industrial packaging products produced by pulp molding technology are truly environmentally friendly products. They use natural plant fibers or waste paper as raw materials, and there is no pollution in the production process and use process. In addition to its positive role in replacing disposable plastic tableware, molded pulp paper trays are also widely used in industrial products as packaging for electronic products. Molded pulp paper trays are gradually entering the mainstream of commercial activities. It is currently foamed plastic. The product is a good substitute product, and the pulp molded paper tray industry is booming.
5. The reason why the pulp molded paper tray has developed rapidly and has good prospects is that it has unique performance advantages:
(1) The process technology is simple and practical, and there is basically no pollution in the production process, which meets the requirements of cleaner production. In addition, each process of its production line, except that the management of the automatic control system requires high quality of personnel, the rest are all skilled technologies, which can be mastered after short-term training, and the degree of localization of its equipment is very high, which is very conducive to the popularization of the project. Promotion, which is also a convenient condition for quickly taking advantage of the environmental protection advantages of pulp molded paper trays.
(2) Wide sources of raw materials and cost. It is mainly made of waste paper or annual herb fiber pulp. The raw materials can be adapted to local conditions.
(3) The product has high strength, good plasticity and cushioning performance.
(4) The weight is light, the recycling cost is low, and it can be used repeatedly.
(5) Good protection, interchangeability and spring-loading performance.
(6) From production and use to waste disposal, there is no pollution to the environment. The water consumption in the production process is small, no waste water is discharged, and environmental pollution is reduced.
(7) Good air permeability, which has unique advantages for the packaging of fresh products.
(8) Pulp molded products have good water absorption, hydrophobicity and heat insulation. If special additives are added in the production process, it will also have special properties such as water resistance, oil resistance, and high temperature resistance.
(9) Modern production technology can realize high-speed, automated mass production.
6. Because the pulp molded paper tray has sufficient raw materials, it is pollution-free during production and use, has a wide range of applications, low cost, light weight, high strength, plasticity, cushioning, interchangeability, good spring-loading performance, and can be repeated It has the characteristics of use, recycling and reproduction, so it has strong vitality and broad application prospects. Its economic value and replacement status have been confirmed by the international community.
7. According to the scope of application, there are two main categories of pulp molding: disposable environmentally friendly tableware and environmentally friendly packaging products, both of which have been widely used.
