With the rapid development of economy, customers have higher and higher requirements on product packaging. It is under these conditions for functional coatings, which has promoted a technical innovation of coatings for corrugated cardboard boxes in the United States. Today, China, which is aiming for rapid economic development, further promotes the use of new functional coatings and strives to promote the development of the packaging industry.
The paper coatings currently used generally have the following properties:
Waterproof paper coating
The traditional waterproof carton adopts waxing. The waxed cardboard will definitely affect the color of the paper. The gray style is always less colorful, which affects the final packaging style. In addition, waxing must increase the weight of the carton and affect the degree of recycling. The series of water-based coatings not only have a small coating amount, but basically do not affect the reprinting ability and adhesion of the carton, making our carton beautiful and strong. Some of the waterproof coating paper can be made into a water tank, which can keep goldfish for 7 days, and the carton is still strong and does not seep.
Corrugated reinforced coating
This is a brand-new application field of water-based paper coatings. In foreign countries, most of the corrugated cardboard boxes are single, but at present, most of them use multi-corrugated cardboard to improve the strength of the cardboard boxes. With corrugated reinforced coatings, the Fiber series in the United States uses special macromolecular polymers to act between the pulp fibers to enhance the strength of the carton. Not only can we use low-gram paper, but also reduce the number of cardboard corrugations. The degree of reinforcement of corrugated reinforced coatings is related to the type of paper and fiber properties.
Moisture-proof paint
Waterproof coating can prevent the penetration of water, but often cannot prevent the passage of water vapor. For the preservation of food, we not only require water isolation, but also need to prevent the penetration of water vapor. At present, laminating paper is generally used for packaging in China, and the use of Vaporcoat's moisture-proof coating not only simplifies the production process of packaging paper, but also can be 100% recycled, which reduces packaging costs and is more environmentally friendly. Exquisite fresh tea packaging, packaging after using moisture-proof paint, so that tea still breathes in the bag. Instant paper is like our human skin.
Grease-resistant coating
When we bought a piece of pizza outside and got it in our hands, the grease in the box had penetrated, and it was even found that the pizza had stuck to the box. And when our carton is coated with grease-resistant coating, the pizza that customers see is completely different, fresh and complete, and very appetizing. Today, developed countries in Europe and America have long used grease-resistant coated paper as food packaging, such as meat, poultry and snacks, chocolate and other packaging.
Wear-resistant coating
Wear-resistant paper coatings are designed to reduce the friction of goods during transportation. Foam and other similar products are generally used in our country, especially the packaging of the home appliance industry. However, in addition to environmental issues, similar manufacturers must use packaging materials of multiple materials at the same time. The American NomarTM series of wear-resistant smooth coatings reduce the original hardness of the paper and form a special coating structure on the surface of the paper to reduce the friction between the original paper and the surface of the home appliance. Protect the surface of home appliances intact. Of course, wear-resistant coatings go far beyond these functions.
Special coating
The special coatings currently used are mainly the following: corrosion-resistant coatings, fire-resistant coatings, anti-static coatings, release coatings, etc.
Corrosion-resistant coatings are mainly used to protect metal parts such as steel, iron and copper. After being coated on the surface of the carton, the American Rustban series can effectively prevent the oxidation of the packaging metal, so that the packaged metal parts will not be rusted and tarnished. Many manufacturers can make the paper have anti-corrosion performance according to the needs of customers, and prevent the leakage of oil stains on hardware accessories.
Fire retardant coatings, we all know that corrugated paper is a flammable product. In some occasions, there are certain fire protection requirements for packaging. At this time, we can use fire retardant coatings. American PyrobreakTMEX series of fire retardant coatings can effectively prevent fire retardant coatings in some cases. Carton burning. If the paper's fireproof and fireproof coating can pass the test of ASTME-162, ASTME-84, TAPPI461 and NFPA30, then it is considered to be a coating suitable for production.
Anti-static coatings generally have anti-static requirements in the packaging of some electronic components. At present, the packaging of these products in China mainly uses anti-static plastic bags, which are then packaged and transported in cartons or plastic boxes. In terms of operation, there are many processes and the cost of packaging is relatively high. After American Staticban series anti-static coatings are applied to corrugated cardboard boxes, the surface of the cardboard boxes has the functions of conductivity and electrolysis, which can effectively protect electronic components from the hazards of static electricity and other charges. The use of anti-static coatings in cartons or cartons to package electronic components can reduce the number of steps in the packaging process and, at the same time, reduce the cost of packaging materials.
In addition to being non-tacky, the release coating can also meet the storage of products such as asphalt and rubber, that is, it also meets the heat resistance. After the hot bitumen is poured into the paper bag coated with Michael's release coating, it will not stick to the paper bag after it has cooled.
Outdoor sofa is a kind of furniture for people to rest, relax and entertain in the outdoors. They are usually made of durable materials that can withstand the effects of various climatic conditions. The classification of outdoor sofas is mainly based on materials, design and function.
First, material classification:
