Wrapping paper trays have gradually replaced foam packaging
(1) Pulp molded products are made of plant fiber pulp or waste paper products that can be completely recycled and reused as basic materials, and are made with unique technology and are widely used in food (medicine) storage, electrical packaging, Non-polluting technology-based green products in the fields of planting seedlings, medical utensils, handicraft blanks and fragile liner packaging.
(2) With the development of industry, a large number 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 hole have been formed in the Antarctic and Arctic, giving the earth's ecological environment This caused great harm. For this reason, 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 will be gradually reduced 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 more and more serious and have become a "white pollution" that everyone hates. The waste disposal of these polystyrene foam packaging brings serious pollution to the environment. Burning destroys the earth's atmospheric ozone layer; the piles cannot be corroded and the geological structure is destroyed. 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) The 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 and use processes. In addition to its positive role in replacing disposable plastic tableware, molded pulp products are also widely used in packaging of industrial products, especially electronic products. Molded pulp products are gradually entering the mainstream of commercial activities. It is currently the most popular foam plastic product. Good alternative products, the pulp molded products industry is booming.
(5) The reason why pulp molded products are developing rapidly and have good prospects is that they have 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 products.
(2) Wide sources of raw materials and low cost. It is mainly made of waste paper or annual herb fiber pulp. The raw materials can be adapted to local conditions.
(3) It has good shock resistance and cushioning properties, and the suspension method is used to produce excellent adsorption, which can effectively protect the product from damage during transportation.
(4) The weight is light, the recycling cost is low, and it can be used repeatedly.
(5) Good protection, interchangeability and decoration performance.
(6) From production and use to waste disposal, no pollution to the environment, water consumption in the production process, no waste water discharge, reducing environmental pollution
(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. Various additives can be added according to customer requirements during pulping to make the product resistant to acid, alkali, sunlight, water, oil, leakage, and deformation.
(9) Modern production technology can realize high-speed, automated mass production.
(10) Compared with traditional packaging materials, such as styrofoam (EPS), EPE foam, etc., it has a small volume and can be stacked and stored, saving storage space and transportation costs.
(11) According to the different requirements of users, the surface quality, color, graphics and other appearance elements of the product can be post-processed to meet the needs of product display.
(6) Because the pulp molded products have sufficient raw materials, the production and use process is pollution-free, the application range is wide, the cost is low, the weight is light, the strength is high, the plasticity, the cushioning, the interchangeability, the decoration performance is good, and it can be used repeatedly With the characteristics of recycling and reproduction, it has strong vitality and broad application prospects, and its economic value and replacement status have been recognized by the international community.
(7) According to the scope of application, pulp molding mainly includes two categories: disposable environmentally friendly tableware and environmentally friendly packaging products, both of which have been widely used.
