In fact, there are many reasons for wrinkling when laminating the profile wrapping laminate machine, but the main factors are temperature, pressure, and speed.
Since the profile wrapping laminate machine is not a common product in the market, customers will also have inexplicable questions during use. Below we will analyze the impact of three factors on the working effect of the profile wrapping laminate machine.
First, temperature is the first key factor affecting the operation of the laminator. The adhesive used for pre-coating film is hot-melt adhesive. The temperature determines the melting state of the hot-melt adhesive and the leveling performance of the hot-melt adhesive. If an error occurs, it is more likely to cause wrinkles.
Second, pressure is also a factor that affects the operation of the laminator. While properly controlling the laminator and the appropriate temperature, appropriate pressure should also be used, because the surface of the paper itself is not very smooth, and only under the pressure, the hot melt adhesive in the state of viscous flow will drive away the air process on the surface of the printed matter. Fully wet the surface of the paper print. This is actually the main reason for the wrinkle caused by the profile wrapping laminate machine.
Third, speed is the last factor that affects the effectiveness of the laminator. The change in speed determines the time it takes for the pre-coated film and paper print to achieve bonding.
The above is the analysis of the three main factors that affect the wrinkle of the profile wrapping laminate machine when laminating.
