When it comes to food bags, we all know that the food we eat on a daily basis comes in various types of outer packaging, which is called food packaging bags. 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?
They are: improper selection of adhesive, process issues, and substrate reasons. Improper selection of adhesive: The adhesive itself has a deep 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 monotonous too fast, causing the solvent on the surface of the adhesive layer to evaporate and form a crust on the surface. Then, when the heat deepens into the inner part of the adhesive layer, the solvent under the film vaporizes and breaks through the adhesive film to form a ring like a volcanic vent, circle by circle, which also makes the adhesive layer opaque.
Composite rubber rollers or scrapers have drawbacks, such as not being able to press at a certain point, forming a neutral gear and not being clear. There is too much dust in the ambient air, and there is dust in the hot air blown into the drying duct after gluing. Sticking to the surface of the adhesive layer, sandwiched between the centers of two base films during lamination, with many small dots forming an opaque structure.
