There are various types of food bags, such as color printed food bags, transparent food bags, high-temperature steamed food bags, etc. So what are the reasons for the quality problems caused by the commonly used transparent and empty food bag process?
The editor will summarize the problems for a wide range of users: improper selection of adhesives, process issues, and substrate reasons. Improper selection of adhesive The adhesive itself has a dark color; The adhesive lacks fluidity and poor flattening ability, and cannot be fully spread on the base film.
Technological issues. The inlet temperature of the drying channel is too high or there is no temperature gradient, and the inlet temperature is too high and dry too quickly, causing the solvent on the surface of the adhesive layer to evaporate sensitively and form skin on the surface. Then, when the heat deepens into the interior of the adhesive layer, the solvent under the skin film vaporizes, breaking through the adhesive film to form a ring like a volcanic vent, making the adhesive layer opaque.
Composite rubber rollers or scrapers have drawbacks, as they cannot be pressed at a certain point, forming a neutral gear and being opaque. There is too much dust in the ambient air, and there is dust in the hot air blown into the drying duct after gluing.
