Promising environmental protection packaging materials

The four pillars of modern packaging and printing—paper, plastics, metals, and glass—have the fastest growth in paper, the lowest price for paper, and the wide availability of raw materials, and unlike plastics that are not easily dissolved, they are not as fragile as glass. Heavy metal, easy to carry. In addition, paper products are prone to decay and can either recycle recycled paper or use plant fertilizers, reduce air pollution, and purify the environment. Here, compared with the three major plastic, metal, and glass packagings, paper packaging was identified as one of the most promising green packaging materials.

First, green packaging and printing paper bags

Donghua Paper Co., Ltd. and Tianjin Daxing Special Paper Research Institute jointly developed a new type of environmentally-friendly, high-strength embedded green packaging and printing bag paper at Donggong. The product uses waste paper as the basic material of paper. At the same time of continuous operation, the water-soluble yarn is once formed into a high-strength embedded green packaging and printing bag paper. In the production process, no pulping, no acid, alkali, and waste liquids are eliminated. The use of renewable resources to implement green packaging projects also effectively solves the problem of white pollution in environmental protection. This product has a good burst resistance, moisture resistance and anti-counterfeiting properties as a high-strength embedded group long green packaging printing product. The water soluble yarns in the middle grade can be dissolved in 95°C water and can be recycled. The National Packaging and Printing Quality Supervision and Inspection Center has detected that all the products have reached the standard of superior products, and have obtained technical approval from Japan, South Korea, Taiwan and other countries and regions.

Second, the paper mold Pulp model is the waste paper or finished pulp broken into mud, through the vacuum adsorption, molded into a product process, referred to as paper mold. Usually divided into two categories: the use of finished pulp as raw materials for production of fast food boxes, convenient bowls and other household items, use of waste paper as raw materials for the production of packaging, gaskets, filling materials to replace foam plastic industrial supplies.

Paper molds are emerging as a result of the problem of foaming plastic pollution. Due to the increasing "white pollution" caused by foamed plastics and the difficulty of waste disposal and high recycling and recycling costs, developed countries in the world have already banned production, sales, import, and use. After many years of trial and comparison, paper molded products have become the best alternatives. The product can be similar to a plant in a recycling environment and rot decomposition by itself. Its unique geometric structure, with shock, impact resistance, as well as anti-static and paper structure itself elasticity, equal or superior to the foam plastic in the force value test. For this reason, the European Union's packaging printing and environmental regulations promulgated in 1991 clearly stipulated that “the use of polystyrene (PS) foam in packaging and printing should be avoided and pulp model products should be used instead.” International Organization for Standardization issued ISO 14000 product (environmental management standard system The main point is: "The heat and the company's access to raw materials, product manufacturing, packaging, printing ink, after-sales service and use, until the extreme processing and other aspects, must meet the principle of not destroy the environment, do not produce pollution, easy to recycle" . Product manufacturing companies consciously implement this standard, reflecting the company's social responsibility and reputation.

Mold products have the following characteristics: The raw materials for paper-based packaging prints are waste paper, which will not create obstacles to the environment and recycling, and are beneficial to the export of manufacturers' products. Paper mold packaging prints have a wide range of adaptability; comprehensive costs are low, paper mold technology It is simpler than foamed plastic, short in production time and cycle, low in energy consumption and raw material cost, anti-static, anti-corrosion and shock-proof performance better than foamed plastic. Knowledge The protective function of fired plastic products is determined by the buffering properties of their materials. The geometrical mechanical structure of the paper molded product and the material itself are integrated and cushioned. In the force value test, the creep and plastic variables are better than the foaming. According to the requirements of different packaged products, the strength agent can be added to achieve a variety of functions. This is not possible with the single physical properties of the plastic. Paper mold products can be stacked and stored to reduce transportation and other expenses.

Paper mold products have grown from original egg trays to thousands of packaging and printing products. The progress of basic equipment and technology has shown great vitality. Nowadays, paper mold packaging is widely used in developed coastal regions. It reduces costs and improves competitiveness for enterprises. Establish a corporate image and provide new development prospects.

Third, the transfer of metal cards Vacuum aluminum transfer cardboard, commonly known as the transfer of gold cardboard. This gold paper is not only comparable in gloss to cellophane, but also has a matt color. Therefore, the transfer of gold paper is an internationally recognized enveloping packaging material because of its high quality and ease of use. At present, there are two printing and compound types of card paper that are used in the domestic packaging industry. As a new type of vacuum sprayed aluminum paperboard that encloses packaging materials, the introduction and improvement of its production technology has caused domestic packaging materials manufacturers and Close attention to packaging printing.

Vacuum aluminum spray paper (commonly known as aluminum paper in the south), plated filter paper, and vaporized paper are the green materials for the packaging and printing industry, which are increasingly used internationally. Because of its noble and beautiful metal texture, relatively low material cost, 100% continuous packaging flexibility, stable and reliable printing performance, and biodegradable, environmentally friendly properties, it is increasingly appreciated by people.

The vacuum ejected aluminum transfer paperboard has the following advantages over the conventional gold card paper:
The auxiliary materials used in the production of aluminum spray paper are odorless, non-toxic and meet the requirements of food hygiene. Can be widely used in tobacco, wine, tea, food and other products exquisitely packaged and printed, such as good cleanliness, high smoothness, bright color, bright appearance, etc., printing performance and mechanical processing performance is excellent, suitable for gravure, letterpress, plastic , Flexo, screen printing and other advantages, but also embossing, die-cutting, and even embossing; degradation of the recovery performance, easy to handle and recycling, in line with environmental requirements, is an essential export material.

Fourth, the entire paper drum

The full paper structure paper drum is a kind of better green packaging and printing variety. Compared with the traditional iron hoop paper drum, it has eliminated the iron hoop and the wood bottom cover and is a kind of paper bucket with a completely paper structure. The equipment for the production of full-paper structural barrels, due to the elimination of iron and wooden parts, eliminates equipment such as punching machines, shearing plates, and the like. From the equipment itself, energy consumption is greatly reduced, noise is eliminated, and the traditional iron hoop paper The iron parts of the barrel must be pickled, brushed, and sprayed, which inevitably causes pollution to the environment. Therefore, the production of a full-paper structure barrel greatly reduces the environmental pollution in the production process. The production of full-paper structure also has the following advantages: raw material singulation, reduction of management links, elimination of iron hoops, etc., simplification of processing procedures, reduction of labor intensity, improvement of ergonomics, and increase of profits: From the point of view of packaging development, paper structure paper The barrels not only meet the purpose of green packaging and environmental protection, but also meet the export packaging needs. Is an ideal packaging material
