Pulp molding project mainly produces environmental protection food packaging products and industrial packaging products, mainly involving biodegradable plant fiber molding environmental protection packaging products industry. Environmental protection food packaging products are mainly environmental protection tableware (meal bag), industrial packaging products developed today, mainly exquisite products industrial packaging (boutique work bag), meal bag and boutique work bag is mainly wet-pressing plant fiber (pulp) molding products (Pulp molding products by mold drying method).

Pulp molding products are divided into two main categories: wet-press pulp molding method and dry-press pulp molding method. The products are called wet-press pulp molding products and dry-press pulp molding products accordingly.

Wet-press pulp molding products are plant fiber (pulp) molded products with a certain concentration of pulp, adding the right amount of additives, and dried and shaped in the hot press mold.

Dry-pressed plant fiber (pulp) molded products are plant fiber (pulp) molded products with a certain concentration of pulp, adding the appropriate amount of additives, after suction and filtration molding, the wet blank out of the mold in a free state after baking or air-drying to a certain dryness into the mold for shaping.

Wet press type plant fiber (pulp) molding products are produced by wet press type plant fiber (pulp) molding machine for pulp molding products by mold drying method.

In terms of precision and surface flatness of the products, the wet-press type plant fiber (pulp) molding products are much better than the dry-press type plant fiber (pulp) molding products.

The wet press type plant fiber (pulp) molding machine refers to the production equipment dedicated to the production of plant fiber (pulp) molded products from plant fiber (pulp) as raw material, through the process of suction and filtration molding and drying and shaping in the hot press molding mold.

The earliest pulp molding production began with dry-press vegetable fiber (pulp) molding method. The technology involved in biodegradable vegetable fiber molded environmental protection packaging products and its initial products were introduced in Denmark in 1917 and belonged to dry-press vegetable fiber (pulp) molding, which entered the mechanized production stage in the 1930s and only produced automated production lines in the 1980s. The technology, equipment and products in the United Kingdom, Denmark, the United States, France, Iceland, Japan and Canada and other industrialized developed countries started earlier. China since the mid-1980s by the China National Packaging Corporation Hunan Plant Fiber Molding General Factory in Hunan Xiangtan from France to introduce the first automatic rotary drum paper mold products production line, are dry-pressed plant fiber (pulp) molding.

In 1992, Hangzhou Machine Research Institute of the Ministry of Light Industry started to study the wet press type plant fiber (pulp) molding machine, which is considered the ancestor of the automatic wet press type plant fiber (pulp) molding machine in China. After more than ten years of production practice, this technology and products through continuous innovation and upgrading, has made a relatively large achievement, promote the paper tableware and paper packaging products in the country's extensive implementation, but also make China's plant fiber molding environmental protection packaging products industry in the forefront of the international. However, the main focus is still on manual equipment.

At present, China's wet press plant fiber molding production line for the production of environmentally friendly tableware, there are a small number of fully automatic plant fiber molding production line manufacturers, but the number is not much. Most manufacturers are manual equipment or manual equipment with a mechanical arm, is a simple and crude automation, just like a clothes-rubbing board with a mechanical arm wants to become a washing machine, the main problems are as follows.
(1) low production capacity. Existing domestic plant fiber molding environmental protection tableware production enterprises to direct pressure manual plant fiber molding production line, the number is not much.
(2) labor intensity, the working environment is harsh. Workers have to be in the 40 degrees in the high-temperature workshop for manual labor.
(3) Quality assurance is difficult. As each link is operated manually, the proficiency of the workers directly affects the quality of the products.
(4) Low safety factor. The use of direct-press manual plant fiber molding line is carried out in manual workshop production mode, which is easy to cause safety accidents.
(5) Poor sanitary condition of tableware. Due to the use of manual plant fiber molding line, each link is manually touching the products by hand for production, inspection and counting, packaging. The existing manual plant fiber molding line manufacturers use workers mobility, workers work at high temperature machine for 8-12 hours, there will be a lot of sweat outflow sticky to tableware. A few seconds of UV disinfection only irradiates one side of the product, while the reverse side is not irradiated, and the products are packaged together on the front and back or do not achieve the disinfection effect. UV disinfection of products also need to be manually counted, packaging, disinfection in front and contaminated by the back of the manual.
(6) The strength of the products is not enough. Domestic plant fiber molding equipment mainly uses cylinder to press the products directly, the cylinder's closing force is not high, the density of the products is low. The automatic plant fiber molding production line equipment system used in this project has high pressure, high density of products and good strength.

China has invested a lot of human and material resources in the development of plant fiber molding products. In the past two years, with the great increase in demand for plant fiber molded tableware in Europe, the United States, Japan and Korea, the wide application of plant fiber molded products in various industries, and the promotion of national policies, the industry has been developing rapidly. At present, China's plant fiber molding industry is in urgent need of automatic, high-capacity, stable performance of the automatic plant fiber molding production line equipment with its unique technology to solve the current problems of the industry. Specific measures should start from the following aspects.
(1) Adopt fully automated, high output, no manual contact, and low energy cost plant fiber molding product lines.
(2) Produce pulp for plant fiber molded environmental tableware with good hygiene and excellent performance, without fluorescent whitening agent plant fiber.
(3) from the packaging design, set up environmentally friendly design ideas, increase the "green packaging" research and development and promotion and application.

China's plant fiber environmental protection packaging industry, although a late start, but the development of fast. Currently facing the problem of relatively uneven development. Some enterprises have reached the international advanced level of technology and products, but there are still many enterprises, especially some hastily launched small and medium-sized enterprises, the production and sales of plant fiber fast food utensils and industrial packaging materials about 30 to 50% unqualified, there are backward production technology, high production costs, product quality is unstable, the market is difficult to promote and other issues.

The construction and operation of pulp molding projects in all aspects should always be based on the principle of technology as the guide, quality as life, strict development of production processes, control production costs and improve product quality.

At present, the pulp molding equipment reaching the international advanced level has the following characteristics.
(1) Fully automatic, realizing forming, shaping and edge cutting in one.
(2) High productivity, low energy consumption, low labor cost, reduce the direct production cost of products.
(3) Smooth operation and low failure.
(4) Clean and comfortable operating environment for workers.
(5) One machine for multiple uses, the same machine is suitable for the production of "environmental protection tableware", "pulp molded cup lid with inverted buckle", "high-quality small angle industrial packaging", "high-quality egg carton and egg tray, and fruit tray". "Fine egg cartons, egg trays, fruit and vegetable trays, etc.
(6) Safety fully enclosed protective safety door, the machine is automatically stopped when the door is opened during operation.
