Cause Of Insufficient Transparency Of Stretch Wound Film

The products directly sold by the manufacturers of stretch and winding film can be used in many industries. In the process of use, we find that the transparency of the products is not enough. What is the reason for this?
When manufacturing products, it is found that the temperature of drying it is too high, if its temperature is too high, drying too fast, so that the solvent on the surface of the glue layer quickly evaporates, surface crust, and then when the heat goes deep into the inside of the glue layer, the solvent under the coating vaporizes, breaks through the glue film to form a ring like a volcanic vent, round and round, but also makes the stretch winding film opaque. There is too much dust in the air environment of the manufacturer. There is dust in the hot air blown into the drying duct after gluing. Stick on the surface of the rubber layer, composite sandwiched in the middle of the two base film, there are many small points, causing opacity.
The amount of glue on the stretch winding film is insufficient, there is a blank, and there is a small air bubble, resulting in speckle or opacity. The amount of glue should be checked to make it adequate and uniform, which brings us great benefits and maintains the stability of the performance.
