Innovation of environmentally friendly adhesives in the production process of PE coated paper and its industry significance

1. Basic overview of PE coated paper
PE coated paper is to coat a layer of polyethylene (PE) film on the surface of paper to improve the waterproof, moisture-proof and tear-resistant properties of paper. This material is widely used in food packaging, electronic product packaging, advertising and other fields, and is favored for its excellent physical properties and environmental protection characteristics. In the traditional PE coated paper production process, the selection and use of adhesives often have a certain impact on the environment. The innovative application of environmentally friendly adhesives has become an important topic in the production process of PE coated paper.

2. Innovative application of environmentally friendly adhesives
1. Water-based adhesives
Water-based adhesives are adhesives that use water as a solvent or dispersion medium. They are non-toxic, odorless, non-flammable, easy to clean, etc., and meet the current environmental protection requirements. In the production of PE coated paper, water-based adhesives can be evenly and stably coated on the surface of paper, forming a good bonding effect with PE film. Compared with traditional organic solvent adhesives, the use of water-based adhesives can significantly reduce the emission of volatile organic compounds (VOCs) and reduce pollution to air and water resources.

2. Plant-based adhesives
Plant-based adhesives are an environmentally friendly adhesive made from natural plants through biochemical processes. It is not only renewable and degradable, but also provides excellent bonding properties. In the production of PE coated paper, the application of plant-based adhesives can not only reduce dependence on petroleum resources, but also reduce carbon emissions in the production process. Plant-based adhesives also have good biocompatibility, are harmless to the human body and the environment, and are in line with the green and healthy production concept.

3. Biodegradable adhesives
Biodegradable adhesives are adhesives that can be completely decomposed by microorganisms under natural conditions. In the production of PE coated paper, the application of biodegradable adhesives can solve the problem that traditional adhesives are difficult to degrade and reduce the long-term burden of waste on the environment. With the continuous development of biodegradable technology, the performance of biodegradable adhesives has been continuously improved, and its application prospects in the production of PE coated paper are becoming increasingly broad.

3. Other innovations in the production process of PE coated paper
In addition to the innovative application of environmentally friendly adhesives, the production process of PE coated paper also involves innovations in many aspects, which jointly promote the green transformation of the industry.

1. Improvement of coating technology
Coating technology is a key link in the production of PE coated paper. In recent years, with the continuous improvement and innovation of coating technology, such as the application of slit extrusion coating, micro-concave roller coating, and blade coating, PE coating can be more evenly and accurately coated on the surface of paper. These technological improvements not only improve the quality and performance of the products, but also reduce energy consumption and waste emissions in the production process.

2. Introduction of automated and intelligent production lines
With the continuous development of automation and intelligent technology, the production line of PE coated paper has also achieved a high degree of automation and intelligence. These production lines can accurately control key parameters such as coating amount, coating thickness, and paper speed to ensure the stability and consistency of product quality. The introduction of automated and intelligent production lines also reduces labor costs, improves production efficiency, and makes the production of PE coated paper more efficient and environmentally friendly.

3. Optimal selection of raw materials
In the production of PE coated paper, the selection of raw materials is crucial to the quality and performance of the product. In recent years, some companies have begun to use high-quality PE resins and environmentally friendly additives as raw materials to improve the waterproofness, tear resistance and environmental performance of the products. Through the optimization of the proportion and fine processing of raw materials, the production cost can be further reduced and the market competitiveness of the products can be improved.

4. The significance of environmentally friendly adhesives to the PE coated paper industry
The application of environmentally friendly adhesives in the production of PE coated paper not only meets the current global urgent need for environmental protection, but also promotes the green transformation and sustainable development of the industry. By using environmentally friendly adhesives, the PE coated paper industry can reduce pollution to the environment, reduce energy consumption and waste emissions in the production process, and improve the utilization efficiency of resources. The application of environmentally friendly adhesives can also improve the quality and performance of products, enhance the market competitiveness of products, and bring greater economic and social benefits to enterprises.
