0010010 nbsp; 0010010 nbsp; In order to prevent corrugated cardboard boxes from opening, it is important to choose the right adhesive. Once the glue is used incorrectly, the entire batch of corrugated boxes will be opened.

The basic principle of choosing glue for pasting boxes is to choose different glues according to the different surface treatment methods of corrugated color box facial paper.

If the sticky position of the corrugated color box is that ordinary paper surface and ordinary paper surface are glued, ordinary white latex can be used when gluing the box;

If the label is glued to the paper surface and the film surface (including the light film and the dumb film), paper and plastic water need to be selected when pasting the box, and different paper and plastic water, such as PET or OPP, must be selected according to the different film materials When the film surface is pasted, different paper and plastic water should be selected separately;

If the paper surface is bonded to the surface of the UV varnish, you need to use UV glue when gluing the box;

If the paper surface is bonded to the polished surface, you need to use polishing glue when gluing the box. For manual paste box or paste box, the speed is slow, we should choose glue with long opening time; automatic paste box or paste box with fast speed, should choose glue with short opening time.

When choosing glue for glue boxes, the working environment of the glue box workshop also needs to be considered.

The glue used in winter is different from the glue used in summer, because the glue of the same brand and the same batch is digitally printed at different ambient temperatures, and the viscosity is also different. The lower the ambient temperature, The higher the viscosity of the glue. Regardless of whether it is winter or summer, glue is required to achieve a viscosity that is convenient for production operations during the paste box production process.

Due to the low temperature in winter and the high viscosity of the glue Esko, if the corrugated box manufacturer adds a thinner to adjust the viscosity of the glue, the adhesion of the glue will be affected to a certain extent. Therefore, in order to maintain the adhesion of the glue and the normal reaction mechanism of the glue, the glue used at a lower ambient temperature needs to be adjusted accordingly. The Beiren Group is also very mature in the South. The reason why the glue cannot be used directly in the north.

In addition, the use environment of the corrugated color box should also be considered.

If the corrugated color box behind the paste box needs to be sent to a high-temperature environment for use, it is necessary to select a glue paste glue with higher temperature resistance;

If the corrugated color box behind the paste box needs to be sent to a low-temperature environment for packaging design, you need to use low-temperature paste glue. Glazing performance.

If the automatic folder gluer is equipped with a spray gun, the corresponding glue spray should be selected. At the same time, the performance of the spray gun control system must also be considered. If the spray gun control system is a hot melt method, hot melt spray glue needs to be selected; if the spray gun control system is digital printing without heating in China, cold spray glue should be used.
