Digital printing of vulcanized transfer film
A rubber specific transfer film based on vulcanization process, comprising a substrate and an ink layer printed on the substrate, wherein the melting temperature of the substrate is not higher than the vulcanization temperature in the vulcanization process, and the material of the substrate can dissolve with rubber at the vulcanization temperature. The present invention also provides a vulcanization transfer printing method for rubber products, in which the rubber specific transfer film described in the present invention is attached to the surface of the rubber semi-finished product, and subjected to a pressure of 6-11kg/cm at 140-160C
Cold laminated film
Cold layer film is made of transparent BOPP processed with adhesive. According to the texture of the film surface, it can be divided into light film, matte film, frosted film, star phantom film, holographic film, and special textured protective film. Light film, matte film, and frosted film are widely used in advertising production. Cover the manually or cold pressed photo printing image with a cold pressed film to prevent scratches, contamination, or wetting of the image (printing surface) and protect the image
Cold film can enhance the texture of the image and protect it from scratches and water. However, photo images cannot be highly resistant to corrosion and UV erosion. UV rays can penetrate the cold film and cause the image to fade. Over time, the cold film can also become brittle. Can be widely used in wedding photos, oil painting production, calligraphy and painting, outdoor posters, advertisements, various pictures, documents, materials&hellip& hellip; wait...... Used for large-scale advertising, architectural decoration renderings, background decoration, etc., using cold laminating film for better protection effect

Hot pressed film
Hot pressed film is a physical and thermal property that forms a molten state at high temperatures. After cooling treatment, a sealed protective space is formed. Hot laminating film requires two processes, hot and cold, to form and maintain stable effects for a long time. However, due to the complexity of the process, specialized machines must be used to produce it, which is a universal method, so the cost is relatively high
Hot laminating film refers to the process of pre gluing and rewinding plastic film, and then laminating it with paper printing. It is first coated by a pre coating processing factory according to the usage specifications and format. After rewinding, the adhesive liquid is applied to the film for the manufacturer to choose from. Then, it is compounded/laminated/coated with adhesive on the film, and heated and pressed together with the paper printed product to form a paper plastic product processing technology. After coating, the printed products have a thin and transparent film on the surface, which makes the surface smoother and brighter, thereby improving the glossiness and fastness of the printed products. The graphic and textual colors are more vivid, full of three-dimensional sense, and also play a role in waterproofing, stain resistance, wear resistance, folding resistance, chemical corrosion resistance, etc

Low surface tension of thin film materials leads to ink loss
Generally speaking, the surface tension of thin film materials needs to reach 38 dynes or above to ensure normal printing, and 42 dynes or above is required for ink to adhere firmly. If ink drop occurs during the printing process, the surface tension value of the material can be tested using a Dyne pen. If it is lower than the above standard, it is recommended to use online corona discharge or coating with base oil to increase the surface tension of the film material, in order to achieve better ink adhesion effect. If there are no conditions to use the above two methods to solve the problem, low surface energy ink can also be used to try to solve it. At present, many ink manufacturers provide inks specifically for low surface energy materials. Printing companies can solve this problem by testing to find an ink that matches the label material used.
