What are the factors that will affect the pre - coating machine film? There are three main factors: temperature, pressure and speed. The following details and share with you.

Pre-coated laminating machine laminating should pay attention to the first factor: temperature

Temperature is the first hub, fumo pre-coating film with adhesive is hot melt adhesive, temperature determines the molten state of hot melt adhesive, determines the flow of hot melt adhesive function, determines the hot melt adhesive molecules to BOPP film, paper, printing ink layer base material of the diffusion of the three kinds of material such as ability, but also decides the degree of crystallinity of hot melt adhesive, only accurately control the temperature of the working area, In order to make the solid hot melt layer of the pre-coated film on the film melt thoroughly into a viscous flow state, with appropriate activity to achieve wetting and bonding on the surface of the printed matter, and ensure the instant curing after composite, so that the film product to achieve the appearance of smooth, bright enough, good melting degree of the adhesive layer, no crease. And will be able to peel ink.

The temperature control of the film process also affects and determines the change of the film with hot melt adhesive solution when heated, as well as the strength of the new heat. Therefore, strict control of temperature is the primary hub of precoating coating machine.

Pre-coated laminating machine laminating should pay attention to the second major factor: pressure

Pressure in the accurate control of the cladding temperature should also use appropriate pressure, because the surface of the paper itself is not very smooth, only under the action of pressure, sticky flow state of hot melt adhesive will be in the process of driving away the printed surface of the air to fully wet the surface of the printed paper.

Producing colloid to paper printed ink film, paper, molecules diffusion, dislocation, achieve good bonding between, form to print on the surface of the whole complete cover, make prints to brightness, no fog, sub flow smooth, no crease, bonding effect is good, in the case of not buckling, appropriately increase the pressure, to make the hot melt adhesive curing thermoplastic performance to full performance, In order to ensure that the film products in the process of composite and then add, to a variety of physical stripping, impact force and other effects of the device has a strong resistance, in order to achieve the composite printed matter internal structure and surface state to achieve a perfect speed.

Paper laminating is a composite movement in the dynamic process, the speed of movement determines the time of the paper plastic complex in the hot pressing body on the hot pressing working interface, but also determines the laminating machine input temperature, pressure and the actual value of the paper plastic composite produced in the actual production process.

Pre-coated laminating machine laminating should pay attention to the third factor: speed

When the film temperature and pressure, after two factors fixed speed change will make the compound membrane effect changes, and because of the limitation of maximum temperature and the pressure supply, will only by less than the direction of value, and with the speed up, drop significantly, hot pressing force recession, worsen composite effect, run too fast, not firm bonding, there will be fog, too slow, inefficient, And even blistered. Therefore, the composite running speed determines the bonding time of pre-coated film and paper printing.

The actual action value of temperature, pressure and velocity has a certain range. Because of the different equipment, this requires us to find the best value in practice, to ensure that the composite effect of the pre-coated film and for the next process of the nail cover spine from the shell, do not bubble to create a favorable premise.
