core tip: in recent years, due to the worldwide ban on the production and import of polluting packaging products, the foamed plastic packaging industry is shrinking day by day, coupled with the substantial increase in oil prices, which has led to a sharp rise in the manufacturing cost of EPS foamed plastic, and the profits have been sharply reduced, even to a loss, Therefore, it is the large tonnage testing machine often used in the metal and construction industries that has further accelerated the decline of EPS foam plastic out of the market

[China Packaging News] in recent years, due to the worldwide ban on the production and import of polluting packaging products, the foamed plastic packaging industry has shrunk day by day, coupled with the substantial increase in oil prices, which has led to a sharp rise in the manufacturing cost of EPS foamed plastics, a sharp reduction in profits and even a loss, thus further accelerating the decline of EPS foamed plastics out of the market

paper holders can be divided into three categories: industrial paper holders, agricultural paper holders and food paper holders

1. Industrial paper holder: it is mainly used in the lining packaging of household appliances, medical equipment, electrified materials and lighting

2. Agricultural paper tray: mainly used in fruits, poultry eggs, agricultural nutrition bowl, etc

3. Food paper holder: mainly used in food bowls, basins, supermarket food trays, etc

(I) pulp molded products are pollution-free scientific and technological green environmental protection products made of completely recyclable plant fiber pulp or waste paper products as basic materials and adopting unique technology, which are widely used in the fields of traditional plastic granulator equipment (Chinese Medicine), electrical packaging, planting and seedling raising, medical utensils, handicraft bottoms and fragile product liner packaging, etc

(II) with the development of industry, a large number of fluorine-containing substances have risen into the atmosphere, causing large-scale destruction of the ozone layer, on which human survival depends. Thousands of kilometers of ozone layer holes have been formed in the Antarctic and Arctic, causing great harm to the earth's ecological environment. Therefore, the United Nations Environmental Protection Agency has held a world-wide Environmental Protection 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 adopted, which clearly stipulated that countries in the world should gradually reduce or ban the entry of fluorine-containing substances that destroy the ozone layer into the atmosphere

(III) in recent years, plastic products, one of the three major packaging materials, especially expanded polystyrene (EPS) products, have become increasingly serious, and have become a white pollution that everyone hates. The waste disposal of polystyrene foam packaging has brought serious pollution to the environment. The annexation and reorganization of small and medium-sized enterprises have destroyed the earth's atmospheric ozone layer; The geological structure will be destroyed due to the failure of stacking and burying. These foamed plastic products have caused great damage to the earth's environment. Using degradable environmental protection packaging materials to eliminate white pollution and improve people's living environment has become an international and domestic written requirement

(IV) tableware products and industrial packaging products produced by pulp molding technology are truly environmentally friendly products, which 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 playing a positive role in replacing disposable plastic tableware, pulp molded products are also widely used in the packaging of industrial products, especially electronic products. Pulp molded products are gradually entering the mainstream of commercial activities. It is the best substitute for foam plastic products at present, and the pulp molded products industry is booming

(V) the reason why pulp molded products develop 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, in all processes of the production line, except for the high requirements for personnel quality of automatic control system management, the rest are skilled skills, which can be mastered and applied after short-term training. In addition, the high degree of localization of its equipment is very conducive to the popularization and promotion of the project, which is also a convenient condition for quickly giving full play to the environmental protection advantages of pulp molding products

(2) wide source of raw materials and low cost. It mainly uses waste paper or annual herb fiber pulp, and the raw materials can be adapted to local conditions, locally sourced, inexhaustible

(3) it has good shock resistance and cushioning, and uses the suspension method to produce excellent adsorption, which can effectively protect the product from damage during handling

(4) light weight, low recovery cost, and can be used repeatedly

(5) good protection, interchangeability and decoration performance

(6) from production and use to waste treatment, there is no pollution to the environment, the consumption of water in the production process is small, there is no waste water discharge, and environmental pollution is reduced

(7) good air permeability, which is unique to the packaging of fresh products

(8) pulp molded products have good water absorption, hydrophobicity and heat insulation. When pulping, various additives can be added according to the requirements of customers to make the products acid, alkali, sun, water, oil, leakage and deformation resistant

(9) modern production technology can achieve high-speed, automated mass production

(10) compared with traditional packaging materials, such as styrofoam (EPS), EPE foam, etc., the volume is smaller, which can be stacked, saving stacking space and transportation costs

(11) according to the different requirements of users, the surface quality, color, graphics and other appearance elements of products can be post processed to meet the needs of commodity display

(VI) pulp molded products have the characteristics of sufficient source of raw materials, pollution-free production and use process, wide application range, low cost, light weight, high strength, good plasticity, cushioning, interchangeability, good decoration performance, and can be reused, recycled and reproduced. Therefore, they have strong vitality and broad application prospects. Their economic value and replacement status have been recognized by the international community

(VII) according to the scope of application, pulp molding mainly includes disposable environmental friendly tableware and all metal liner with longer service life and environmental friendly packaging products, which have been widely used
