Temperature: It is the first key film, laminating film with hot melt adhesive is the temperature determines the molten hot melt adhesive, leveling determine performance hot melt adhesive, hot melt adhesive molecules to determine diffusion capacity three substances intermolecular BOPP film, printing ink, paper and other substrates, but also determines the degree of crystallinity of hot melt adhesive, only the right to control the temperature of the work area, can the laminating solid heat on the film melting layer completely melted become viscous flow state, with appropriate liquidity to achieve wet adhesion of the printed surface, while ensuring complex immediately after curing. Fumo products to make the appearance of smooth, bright enough, good layer melting degree, no creases. Ink and can peel. Temperature control coating process also affects the changes and decisions to resolve when heated with hot melt adhesive film, as well as new efforts to counter the heat. Therefore, strict control of temperature is the primary key of thermal lamination. According to our practice. Temperature control in about 80 ~ 100C range is more appropriate.

Pressure: the right to control the temperature of laminating while also using the appropriate pressure, because the paper itself is not very smooth surface, and only under pressure, hot melt adhesive viscous flow state will be in the air off the surface of the print process fully wet paper printed surface. Colloidal molecules to produce paper print ink, paper intermolecular diffusion, dislocation, to achieve a good bond, a complete coverage of the entire surface of the print to print to bright, no mist, leveling layer, no creases adhesive works well, without wrinkles, due to increase pressure to solidify the thermoplastic hot melt adhesive can be fully functional performance. To ensure that the composite film product after adding the process. For a variety of physical separation, such as the influence of the impact of a strong resistance. (Such as indentation, bronzing. Hot Melt are leather, etc.) in order to achieve complex internal structure and surface state prints achieve perfect unity.

Speed: paper coating is carried out in a complex dynamic movement. Its movement speed determines the paper-plastic composite body in hot fit together to work on the hot interface residence time, also determines the temperature of the laminating machine input pressure and in the actual production process for paper and plastic complex cooperation bear out The actual role of values. When the film temperature and pressure fixed. The effect of changes in the speed of the film will make changes ensued, but there are limitations due to the temperature and pressure of the upper supply will only change by less than the value of the direction, and with the acceleration, fell significantly, pressing force of the recession, deterioration of the composite effect. Running too fast. Bond is not strong. There will be fog, slow no efficiency. Even blistering. So complex operating speed. Determines the laminating film and paper prints achieve bonding time. Based on our experience in general speed control in about 10-20 minutes off a sheet of paper is more appropriate. (Because of the speed of electronic laminating machine hot rollers small. Speed should slow)

Temperature, pressure, speed the practical effect of the value of three major factors that have a certain range. Because different devices. This requires us to find the best value in the role of practice in order to ensure that the effect of laminating film composite and separated from the shell of plastic nail under the cover of the spine process, non-foaming and create favorable conditions. Composite laminating film, how to create favorable conditions for the next steps (including indentation, bronzing, perfect binding on the cover, etc.), but also the process of coating operation is worth considering the important factors we use laminating film. Laminating film and paper when printing complex. The lower limit is 80C, the upper limit is 100C. Intuitive to complex, high brightness out after hot rollers, no hair spray, roughness, and no blistering as a benchmark in this temperature range, hot melt adhesive from the outer to the inner depths of the whole can be fully accepted and heat role in the colloid modified after blending various materials can be fully exploited, the entire layer completely melted. Produce a real, solid bond, rather than the surface of the shallow, by not bending or re-emerging from the shell heating, blistering.

When the minimum temperature slightly downward brightness composite products will decline. And when the maximum temperature increased slightly, that will iron out the film surface is not smooth, the shape of the different bubbles. (Electronic Fumo This phenomenon is particularly evident) coating temperature just right to grasp the critical work area. Composite effect is not only good, but also make the body close to the crosslinking reaction of the hot melt adhesive hot, colloid curing approximate hard, so when it does not easily re-heated to soften the film proper operating temperature control method, which is fine grasp species is very close to the temperature of the coating crosslinking reaction temperature.
