In recent years, with the continuous advancement of technology, people's living standards have become higher and higher. The purchase of goods requires packaging, and the packaging industry is also developing rapidly, and the box making machine for heaven and earth is getting more and more attention. In addition to manufacturing, attention should be paid to the docking of printing planning and plate-making technology in advance: printing, printing, and post-press negotiation of various technical links play an important role in ensuring quality and improving output power. The matching of box-making technology with previous processes and pre-press plans is no exception. Many times, everyone is confused and confused about the poor adhesion of the cassette molding machine. Some manufacturers complained about poor adhesion of the box forming machine or adhesive. In fact, the difference between a good product or a poor product and a certain link in the middle is relatively small, and a good packaging box product is a problem in the entire process. So what is the solution to the weak bonding force of the cassette molding machine? Today, Lingxian will introduce to you the problem of the sticking box of the heaven and earth lid.
2. Printing and packaging manufacturers must pay attention to the season and climate.
1. The main problem should be the amount of glue applied.
If there is too much glue, it is easy to be squeezed onto the carton mold during the production of the top cover and bottom cover forming machine, which will cause frequent cleaning and greatly delay the normal production of the product. On the contrary, if the glue is too small, it will cause the glue to dry prematurely, making it more difficult to work.
Similarly, when the air humidity is high during the rainy season, the drying time of the paper will slow down. On the contrary, the climate is dry in autumn and winter, and the paper is easy to dry, so the amount of glue should be adjusted accordingly. At the same time, the preservation of glue is also more important. When storing glue, if the seal is not tight, many components of the glue will evaporate and the glue will be easy to dry. If there are other types of glue that volatilize certain substances, it will also cause insufficient adhesion and lead to deterioration of the glue. And lose the bonding ability.
3. When applying glue on the top cover and floor cover forming machine for production, please pay attention to the curing time of the glue.
The fresh packaging reminds everyone that if the curing time of the glue is longer, the production time on the top cover and soil cover forming machine should be extended accordingly. If the curing time of the glue is longer, the production time of the top cover and bottom cover forming machine should be shortened, and the compression of the top box and soil box forming machine should be controlled. When wrapping the noodles, the curing time of the glue is exactly the same. The above is the glue applied by the fresh packaging to the top cover carton
