Adhesive strength and material deformation problems in the production of white cardboard gift boxes

1. white cardboard gift boxes bonding solidity

        white cardboard gift boxes production for bonding adhesive selection is very strict, first of all to understand the performance of different adhesive and white cardboard gift boxes material applicability, while the selected white cardboard gift boxes adhesive also need to take into account the safety and environmental protection, economy, bonding environment, drying speed and other factors. Drying speed and other factors. In the premise of meeting the applicable performance of white cardboard gift boxes and safety and health factors, should try to use the lower price of the adhesive, so as to reduce the cost of production of white cardboard gift boxes. For the liquid class adhesive glue in addition to consider its physical performance indicators, it is more important to consider its safety and environmental performance, the need to test whether it contains formaldehyde, toluene, xylene and other harmful substances. In order to ensure the qualified use of adhesive, Rophone packaging factory to adhesive safety and health a solvent residue test, according to the test results of the analysis of the two adhesives are in line with the production of safety and health guidelines.

        The above two adhesives have similar performance and are suitable for the production of white cardboard gift boxes. white cardboard gift boxes cover and edge bonding with laminated paper are more often used adhesive PV-9098, which dries slowly, but the price is cheaper than adhesive PV-9091, and adhesive PV-9098 can be used in the glue machine. 9098 is used smoothly in the glue machine, and the laminated paper is glued evenly and stably. After the bonding is completed, the white cardboard gift boxes shells are flattened with a flattening machine, and the white cardboard gift boxes edges are pressed with a bubble press to avoid bad results such as poor bonding and bubble generation. In the white cardboard gift boxes flattening process before you need to adjust the speed and pressure of the flattening machine, flattening pressure should not be too large, too much pressure will easily lead to the front of the cover pressed out of the glue dot print. Generally, you need to adjust the flattening machine in advance, and choose the appropriate pressure to flatten the leather shell according to different products and adhesive performance. Adhesive PV-9091 is strong, easy to volatilize, because of the strong bonding firmness is mostly used in the leather shell assembly process, after the white cardboard gift boxes cover and the inner box bonding, and then use the bubble press for the pressure bubble process, under a certain pressure, so that the white cardboard gift boxes cover and the inner box bonding more firmly. 2. white cardboard gift boxes material

 2. white cardboard gift boxes material deformation

2.1. white cardboard gift boxes lid industrial paperboard deformation

       white cardboard gift boxes box cover industrial paperboard in the production of material preparation, the relevant staff to determine the industrial paperboard paper pattern to open material, good white cardboard gift boxes production spelling, quota audit, to avoid the gray board cutting after the number of open material is not enough. After the cutting is completed, it must be neatly placed on the cardboard, using a wooden board flat pressed on the industrial cardboard, and then wrapped with cling film and placed in the constant temperature room to avoid sunlight.

       When cutting white cardboard gift boxes, we should pay attention to the direction of the industrial cardboard paper grain, the direction of the industrial cardboard paper grain - a certain degree to determine the overall effect of white cardboard gift boxes molding. The longitudinal grain of industrial cardboard has small deformation when used, while the horizontal grain has larger expansion and deformation during use. In order to ensure the best presentation of the overall structure stiffness and appearance of white cardboard gift boxes, and to avoid the partial deformation of white cardboard gift boxes, which leads to the incomplete closure of the lid of white cardboard gift boxes, in the case of white cardboard gift boxes In white cardboard gift boxes product proofing, the horizontal grooving of the gray board makes it cross with the vertical grain to form a cross grid.

2.2. white cardboard gift boxes inner box industrial cardboard deformation

        After the white cardboard gift boxes are packaged with adhesive tape, they should be neatly placed on the tray, flattened and wrapped with cling film. white cardboard gift boxes are laminated and the inner boxes are pressed with a bubble press to complete the bubble pressing process, so that the laminated paper and the gray board are bonded tightly to prevent the white cardboard gift boxes from creating bubbles. boxes to prevent air bubbles. The white cardboard gift boxes are placed neatly on the tray again, flattened and wrapped with plastic wrap to prevent the white cardboard gift boxes from deformation.

       When cutting white cardboard gift boxes, you also need to pay attention to the direction of the industrial paperboard paper grain, from different paper grain direction after cutting the industrial paperboard stiffness is different, deformation is also different. Generally white cardboard gift boxes production feeding, the long side of the inner box industrial paperboard for horizontal paper grain, reduce deformation, bonding laminated paper is not easy to deformation, forming better results.

        In conclusion, when white cardboard gift boxes are produced in constant temperature and humidity environment, there are still more uncontrollable factors affecting the smooth production, Rophone packaging factory personnel must grasp the various aspects of the production of white cardboard gift boxes to prevent problems before they occur. In the production of white cardboard gift boxes products laminated boxes need to confirm the good die-cutting size, the choice of environmental protection glue, industrial cardboard and many other environmental protection to do, not only can reduce white cardboard gift boxes unnecessary waste, reduce the production cost of white cardboard gift boxes, at the same time It can improve the production efficiency of white cardboard gift boxes and make high quality white cardboard gift boxes products.
