Application of GDR-PLASMA Atmospheric Pressure Plasma Technology in Folding Carton Automatic Folder Gluer

With the ever-increasing demand for carton packaging materials, the market demands not only its aesthetic appearance but also more functional and quality requirements for the packaging carton.

The materials used to process cartons, such as sheets and liners, are no longer simply paper, but more are new materials such as coated paper, glossy paper, laminating paper, or aluminum-plated paper, or they are made directly from PP. PET and other plastic sheets. These new materials bring many performance and quality benefits to the packaging carton, but they also bring new challenges to the cartoning process.

For general paper, water-based cold glue can make them well bonded; and for new materials such as coated paper and glossy paper, because the bond is no longer paper and paper, but paper and plastic, or paper and With other materials, the gluing process is not as simple as before.

Domestic enterprises often use partial coating, partial glazing, surface polishing or slashing paste lines, use of special special glues, etc. Although these methods solve some process problems to a certain degree, but generally, these processes are "The paper box, from the process, efficiency, cost and quality assurance, and still have a certain gap with the ordinary paper box.

So, is there a way, through a certain surface treatment so that the surface of the film or the coating can be bonded like ordinary paper, and at the same time, it can guarantee the firm bonding quality? Yes, the answer is yes!

The German GDR-PLASMA plasma technology produces stable air plasma under atmospheric conditions, or atmospheric conditions, and uses air plasma to treat the surface of the material. For the carton, various plastic coating layers, UV coating layers or various cardboard printing layers are processed.

The role of the treatment mainly comes from two aspects, the first is the cleaning of the surface, the removal of various pollutants; the second is the activation of the surface, a certain physical and chemical modification of the surface film, UV coating or plastic sheet, improve Its adhesion makes it as easy to bond as ordinary paper. The plasma itself is electrically neutral and therefore does not burn the surface when handling some aluminum surfaces. And the plasma is still cold, it does not have any thermal effect on the surface. Processing under normal process settings will not find any treated marks on the surface.

JYS series atmospheric pressure plasma processing system consists of generator, transformer and plasma torch. According to the different types of boxes, such as straight boxes, lock boxes, etc., or different materials, such as different types of cases, such as single-sided paper boxes or double-sided plastic boxes, the system may be configured with different numbers. Spray gun to complete the pre-processing work.

The plasma spray gun is mounted directly on the folder gluer and is usually placed in front of the spray gun or glue coating plate of the glue dispenser. A spray gun can achieve a processing width of 7 mm to 10 mm. The process can meet the needs of high-speed gluing boxes, and even if the line speed reaches 600m/min, it can be effectively processed. The system can be easily and mechanically and electrically integrated with the folder-gluer. It takes only a few minutes to mount the gun onto the folder-gluer.

The treated surface can obtain a surface energy of 72 mN/m, which means that water can spread completely on such a surface. After processing, the use of conventional cold glue can make the coated or glazed paperboard reliably bonded on the high-speed folder-gluer, completely eliminating the need for partial coating, partial coating, and surface grinding and tangling. It is no longer necessary to change different special glues for different cardboards.

For the plastic box, the treated surface can also enhance its applicability to glue, and no longer rely on special glue to achieve high-quality bonding. At the same time, due to the improved surface spreading performance, the generation of air bubbles and the like can also be prevented. The most important thing is that atmospheric pressure plasma treatment allows carton manufacturers to obtain high-quality products with higher quality at a lower cost and higher efficiency.

Adhesive box machine plasma surface treatment equipment advantages: environmental protection / energy-saving / efficient / low consumption

1. After plasma treatment, the surface tension of the material can be increased, and the bonding strength of the carton can be enhanced, thereby improving the product quality;

2. It can use cold glue or low-grade common adhesive instead of hot-melt glue, and reduce the amount of glue used, effectively reducing the production cost;

3.Using plasma technology, it can make UV glue, PP coating and other difficult-to-bond materials use water-based glue to stick very firmly, and eliminate mechanical grinding, punching and other processes, no dust, waste, in line with drugs, food Packaging and other health and safety requirements are conducive to environmental protection;

4. It can be processed online at high speed and can be produced online with the folder gluer production line to increase production efficiency;

5. The plasma treatment process will not leave any traces on the surface of the treated carton and will also reduce the generation of bubbles.
