What is thermal lamination?

The thermal laminating machine is the equipment used to complete the laminating process. Generally speaking, it can be divided into two types: coating film and pre-coating film according to the method used, and two styles: bright film and matt film according to the different film materials. The coated printed matter has a thin and transparent plastic film on the surface, which makes the surface smoother and brighter, improving the printed matter's gloss and fastness and prolonging the printed matter's service life. The printed graphics and texts of the lamination products are more vivid in colour and have a three-dimensional effect.

The thermal lamination machine should mainly avoid curling the printed products after lamination in digital printing products. Therefore, if conditions permit, film on both sides of the substrate as much as possible; if only one side of the paper is covered and the other side is not covered, the single-sided thermal film is very prone to curling. However, it should be noted that the cover of the perfect bound book can only be laminated on one side. Do not cover the second and third covers. Otherwise, the book block and the body will not be firmly bonded.

When the thermal laminating machine is selected, it can also be equipped with a rod to prevent the curling of the laminated printed product, ensuring that the laminated product is flat and not curled. When thermal lamination of printed products, first of all, ensure that the surface of the printed products to be laminated is clean and dust-free, and secondly, pay attention to the appropriate temperature. If the temperature is too high, it will quickly melt the toner and cause the film to blister.

What is the difference between cold lamination and thermal lamination?

The main difference between the two is that "cold lamination" uses glue and the pressure of the cold lamination machine to bond the photo with the lamination and backboard, while "hot lamination" is to complete the picture by the high temperature and high pressure of the hot lamination machine. Framed. In contrast, cold lamination costs less, but hot lamination works better, and photos will last longer after mounting.

What is the membrane of thermal lamination?

The films used for thermal lamination mainly include polyester film and polypropylene film. Generally, polypropylene film is used when covering thinner film, and thicker polyester film can be used for printed products that require additional protection. The price of polyester film is higher than that of polypropylene film, but it has high strength and can better protect the printed product. If both sides of the printed product need to be laminated, choose a polyester film. In the lamination of digital printing products, failures such as curling the printed products after lamination should be avoided. Therefore, if conditions permit, film on both sides of the substrate as much as possible; if only one side of the paper is covered and the other side is not covered, curling is very likely to occur. However, it should be noted that the cover of the perfect bound book can only be laminated on one side. Do not cover the second and third covers. Otherwise, the book block and the body will not be firmly bonded.

In addition, when choosing a laminating machine, you can select a rod to prevent the curling of the laminated printed product, ensuring that the laminated product is flat and not curled—avoiding blistering of products after lamination is also a problem that should be paid attention to in lamination. When thermal lamination of printed products, first of all, ensure that the surface of the printed products to be laminated is clean and dust-free, and secondly, pay attention to the appropriate temperature. If the temperature is too high, it will quickly melt the toner and cause the film to blister. In addition, OPP film can be selected to make the product not wrinkled after folding after lamination. For the selection of lamination materials, the lamination may affect the colour reproduction of digital prints. This is mainly because the movie used in lamination is not necessarily 100% transparent, so that it will affect the colour balance. Therefore, to be on the safe side, you can first try to cover a few samples to the customer to see if the colour of the printed product after lamination meets the customer's requirements and then officially carry out lamination processing.

What is the advantage of the thermal laminating machine?

The temperature can be set according to different use environments, and the thermal lamination film can be softened by heating and hot-covered on the printing medium; electric control, simple operation, one-person operation, labour-saving; fast speed, 200-400 square meters per hour; The ordinary cold laminating machine has the phenomenon of bubbles, wrinkles and deviation, and the yield is high; the cost is low, the cost of traditional cold lamination is 2-3 times that of the hot lamination; it can be hot or cold, and one machine can be used for two purposes; Imported silicone rubber rollers are used, with good material, high parallelism and durability; equipped with imported double emergency stop switches, which can be controlled at any time, flexible and convenient; once an abnormality occurs in work, the operation control can be reversed at any time to reduce the scrap rate.

What are the quality standards of laminating?

The lamination process is to coat the surface of the paper printed product and the plastic film with adhesive and then stick together after hot pressing to form a paper-plastic integrated printed product. The published product, after lamination, has many surfaces. A thin and transparent plastic film is formed, and the texture is smoother, thereby improving the flatness and stiffness of the printed matter, and the coated printed matter has the functions of moisture-proof, waterproof, stain-proof, wear-resistant and chemical-resistant.

The printed matter refined by the plastic film composite process mainly includes the covers of various books and advertising albums, calendars, food boxes, cigarette boxes, wine boxes, toy boxes and another box-type packaging. According to the different properties of paper and ink, the operators engaged in paper-plastic lamination must make the adhesive firmly bond the paper and plastic film into a paper-plastic integrated whole through appropriate temperature and pressure.

(1) Quality standards for lamination products:

1. According to the different properties of paper and ink, the temperature, pressure and adhesive of the film should be appropriate;

2. The film is firmly bonded, the surface is clean and flat, not blurred, with a good finish, no wrinkles, no bubbles, no separation of paper and plastic, and no traces of powder foil;

3. After lamination, the size of the slitting is accurate, the edge is smooth, the lamination area is complete, and there is no obvious curling and scratching;

4. The degree of drying after lamination is appropriate, and there is no phenomenon of sticking to the surface film or paper.

How to purchase a fully automatic laminating machine?

When people buy certain products, they will have higher requirements than before. However, with the rise in prices of many products, although the price is taller, the quality is the same as before. We are buying automatic lamination. What should be the trade-off between price and quality when purchasing a machine?

We all know that you get what you pay for, but sometimes, the quality and price of the products we buy are not proportional. This phenomenon is widespread, but sometimes, consumers will accept reasonable prices. Inexpensive products, so between the price and the quality, we have to analyze it ourselves, mainly depending on the product's actual situation.
