Pulp Molding and Foam Products
Release time：2019-09-09
At present, the commonly used industrial product lining shockproof packaging material is expanded polystyrene. Because EPS has a very stable chemical structure, its waste is placed in the natural environment for hundreds of years without decay and degradation, and it has accumulated a lot of "white pollution" to the natural environment. Pulp molding cushioning shockproof packaging products (hereinafter referred to as PMP) is a waste paper, waste carton paper, paper mill or printing plant scraps as raw materials, hydroponic pulp, ingredients and other processes to prepare a certain concentration of slurry, slurry The vacuum blank is vacuum-adsorbed into a special metal mold, and the formed wet blank is dried and hot pressed.
The production process of PMP is free of waste water and exhaust gas, and the production process is recycled with water. The main raw material used in production is waste paper. The main raw materials are abundant and low-priced. The main raw materials are waste paper. The source is rich and the price is low. It is a comprehensive development and utilization of waste. After completing its buffer shock protection mission for the packaged goods in the process of storage, transportation, sales, etc., the PMP can be recycled and recycled like plain paper, even if it is abandoned in the natural environment. Decomposes into plant fibers.
The shock-proof protection of the PMP to the packaged material is achieved by the elasticity of the fiber itself and its well-designed cavity geometry. Through a large number of practical applications and tests, PMP is enough to protect the packaged material from EPS. PMP is an ideal environmentally friendly alternative to EPS. Compared with EPS products, PMP has the following characteristics:
1. The raw material of PMP is waste paper, which is easy to recycle and will not pollute the environment. It will be beneficial to the export of the products of the producers; the raw materials of EPS are petroleum by-products, which are difficult to degrade, and the recycling value is very low, which causes serious damage to the environment. "White pollution".
2. PMP has a wide range of applications. With the advancement of paper mold technology, small and medium-sized industrial products using foam as lining packaging can basically be replaced by PMP.
3, PMP can be stacked and stored, which is 1/2 to 2/5 less than the storage space occupied by EPS products, which can greatly reduce transportation and storage costs.
4, anti-static: EPS friction is easy to generate static electricity, and PMP is not easy to generate static electricity, which plays a good role in protecting electronic products and home appliances, especially electronic components.
5, anti-corrosion performance: food (such as fruit) storage will release water, packaged with plastic products, its moisture can not be volatilized, easy to make food moldy and rot, and paper products have good breathability, water can be volatilized Come out to achieve the antiseptic effect.
6, anti-shock performance: PMP's shockproof and anti-shock performance is equivalent to EPS products. The protection function of the EPS product on the packaging is determined by the cushioning properties of the material, while the PMP is a cushioning property formed by the combination of its geometric cavity structure and the elasticity of the material itself, achieving a good protection function for the package.
7. Low cost: The raw material cost of producing PMP is far lower than the raw material cost of EPS products, and the production cost is also lower than EPS.
8. PMP raw materials are rich in source and easy to collect, and the price is low; EPS raw materials are petroleum by-products, the source will become increasingly tense, the price will become more and more expensive, and even the exhausted crisis.
In summary, PMP is based on waste paper as the main raw material, which is the comprehensive development and utilization of waste. The production process is closed and closed, no waste water and exhaust gas are discharged, and the cost is low, the shockproof performance is good, and the application is extensive. After the service life is completed, PMP is easy to recycle and recycle, just like ordinary paper. Therefore, the project is in line with relevant environmental protection policies and has been included in the “10th Five-Year” packaging environmental protection new material development project.
With the progress and development of society, human beings face two major problems - the environment and resources, and packaging is closely related to this. Plastic products have become the main packaging materials for a long time due to their good use properties, such as EPS packaging materials and fast food boxes. However, due to its poor degradability, its waste is not rotted in the natural environment for hundreds of years; if it is landfilled, it will occupy a large amount of space and land due to its large volume; if it is incinerated, it will cost expensive special incinerator and be incinerated. At the same time, toxic gases are produced; the current recycling and recycling technology has high recycling costs; therefore, due to the use of EPS products for many years, the human living environment has faced serious "white pollution." Therefore, the active development and development of environmentally friendly alternatives has become a top priority for solving and managing “white pollution”. PMP is known as a “green packaging” product that is environmentally friendly and has been quickly accepted by the market due to its good use properties, especially environmentally friendly properties that are easily degraded in the natural environment.
With the development of the world economy and the awareness of human environmental protection, governments have paid more and more attention to environmental pollution caused by packaging. At present, more than a dozen states of the European Community, Japan, South Korea, and the United States have successively enacted legislation prohibiting or restricting the use of EPS that causes serious "white pollution" to the environment. For example, in the European union countries, EPS products are used as anti-vibration lining packaging products, which are subject to heavy environmental taxes, customs duties and strict customs procedures. High environmental taxes reach 100% of their commodity declaration prices. Products form non-tariff trade barriers, the so-called "green trade barriers."
