In the actual operation of our manufacturer, whether the laminating products can normally complete the factory and meet the requirements of customers, in addition to the quality of the laminating glue itself, it is also related to the supporting factors such as paper, film, equipment accuracy, environment, and operating experience in the composite process. Often in some small details, it will cause unnecessary mistakes, which delays the time and increases the cost, which can be described as losing the wife and folding the army. Next, we will teach you a few tips to save costs. 1.The storage of glue is very important, should be placed in a suitable place according to the product instructions for storage, sunscreen and antifreeze, avoid direct sunlight and other requirements, the remaining glue after use should also be sealed and stored to prevent crust and mold, shorten the shelf life, resulting in unnecessary waste. 2.After the printing ink of the product to be printed, it must be dry and coated with film adhesive. 3.The coating roller of the laminating machine must be cleaned before use to ensure that no other impurities are attached to it. 4.Different coated adhesives should not be mixed and used at the same time to prevent adverse chemical reactions and losses. 5.If there is dust on the surface of the print, in principle, it should be wiped clean in the coating, if the dust is small, you can choose the special adhesive for the coating powder.

With the progress of science and technology, the printing technology industry is also developing rapidly, and more and more adhesives are used in the packaging and printing industry, and more and more varieties are also available. The film coating process is widely used in a variety of packaging, small to medicine boxes, crafts boxes, large to outer boxes and various product packaging. Some coating methods are pre-coated (hot melt type), and some are dry composite (solvent-based). In the late 1990s, with the strengthening of people's awareness of environmental protection, the domestic phase developed a more suitable wet composite technology (water-soluble adhesive), and there were water-based laminating and water-based laminating adhesives that matched each other. Pre-coating process This is a widely used film coating process, in the BOPP film coated with a layer of hot melt adhesive, after cooling into a film, the printing manufacturer in the film directly precoated film heating, in the hot melt adhesive melting state, at the same time through the pressure to make it fit on the print. The process and equipment are relatively simple, no environmental pollution, the product also has excellent brightness, but due to the high manufacturing cost of pre-coating film, large power consumption, the coating speed is slow. Wet laminating process This is a new laminating process developed in recent years, generally using water-based laminating glue coated on BOPP film, without drying, directly with printed matter cold press, roll. Because it does not need drying, the power consumption is only 10% of the coating, about 1.5KW/h, and the coating speed can be doubled, which can greatly improve the work efficiency and reduce the cost. Environmentally friendly water-based laminating adhesive makes the laminating industry completely rid of the toxic, flammable, polluted and other defects brought by the traditional process. And the laminating products have better brightness and clarity, so in just a few years, the traditional laminating process has been gradually eliminated. Sinograce Chemical SA2291 Water based Bopp and paper lamination adhesive.This product is a self-crosslinking emulsion with the advantages of small amount of glue, high peel strength, good toughness, no glue opening when exposed to moisture, deep embossing and shallow embossing, and general use on flat surfaces.

Lovers who like to collect books know that books are exposed to the air and vulnerable to damage because they are placed in the bookcase for a long time, and the edge of the book is produced in this environment. Book edge hot printing technology can not only effectively protect books, but also play a beautification, decorative books, the original purpose of brush gold is to avoid dust falling into the book, and then avoid damage and acidification of the inside pages. Now, the top of the book, the bottom of the book, will be hot printing, but also do a lot of beautiful patterns, colors and so on. Although this hot stamping process is complicated and complex, ordinary hot stamping silver printing is widely used in daily life, as small as badges, buttons, trademarks, plastic handles, etc., to the surface decoration of furniture, has an important role and status in the printing industry. Anhui Sinograce Chemical Co., Ltd. water-based coated adhesive, is a water-based acrylic adhesive. Excellent overall performance, reasonable speed of conjunctiva after coating, fast drying of composite, good stiffness and fastness, high reflective rate, loyal to the primary color, colorless phase elegant; Coated adhesive powder ability is strong, the dry material is easy to clean, the composite product is resistant to rolling line, smashing and embossing, and has good adaptability to hot stamping, gold printing and silver printing. Wide temperature range, good freeze-thaw stability, can continue to use after freezing and thawing; High cost performance, simple process, easy to operate.

According to the different raw materials and equipment, the coating process can be divided into two kinds of coating process and pre-coating process. That is to say, the film used in the coating process is now coated, and the adhesive used is generally solvent-based and emulsion type, prepared according to need. However, the film used in the pre-coating process is pre-coated, and the adhesive used is generally hot melt and solvent volatile. According to the film process of paper printed matter, the film process can be divided into three categories: dry film process. Wet laminating and precoating pressing. Dry laminating method is the most commonly used laminating method in China, which is to coat a layer of adhesive on the plastic film, and then evaporate and dry the solvent in the adhesive through the drying tunnel of the laminating machine, and then bond with the paper printed matter to form a laminating product under hot pressing. Wet film is coated on the surface of the plastic film with a layer of adhesive, in the case of the adhesive is not dry, through the press roller adhesive and paper printed matter bonding, forming a film product. Since the emergence of water-based laminating machine, the process of water-based laminating machine has been popularized and applied, which is closely related to the characteristics of the wet laminating machine, such as simple operation, less adhesive amount, no organic solvent damage to the environment, high strength, high grade and easy recovery. At present, the coating process is more and more favored by domestic packaging manufacturers, and has been widely used in gift boxes, handbags and other packaging. Coating glue manufacturers said that the pre-coating coating method is the coating film manufacturers directly purchase the plastic film coated in advance, and when the film needs to be coated, the film and paper prints are hot pressed on the coating equipment to complete the coating process. The pre-coating process began in the 1990s. The pre-coated film is obtained by applying hot melt adhesive or low temperature resin to the film substrate quantitatively and uniformly with special equipment according to design. According to the coating adhesive manufacturer, the pre-coating coating method eliminates the need for adhesives, preparation, coating and drying, and the entire coating process can be completed in just a few seconds, without polluting the environment, no fire hazards, and no need to clean the coating equipment. At present, the technology has been applied to the field of medicine and food packaging.
