Base material is the base paper carton, paper including corrugated paper and corrugated board paper, white paper board, etc. , they are very sensitive to moisture, under the condition of the damp environment prone to moisture absorption. If beer cartons once be affected with damp be affected with damp or touch water, the intensity will drop dramatically, affect the normal circulation of the products, packing quality and appearance. So, waterproof light oil well in carton manufacturers need to pay attention to effectively control from production source, by the control of raw materials and production technology, to improve the waterproof performance of beer cartons. In the process of production to make the quality control of base paper and keep right, base paper has strong moisture absorption properties, and it is sensitive to air humidity. When the base paper be affected with damp be affected with damp, moisture will increase significantly. So, completes the base paper inventory and warehousing link is very important, considering from the perspective of moistureproof, base paper pile up, the application of wood frame mat is high, and the ground distance should be more than 25 cm, and not get too close to the wall, spacing not less than 40 cm. Stockpiling base paper, therefore, must be kept clean and dry, well ventilated, must not blind stacking the base paper in damp places. Store base paper warehouse temperature should be controlled between 20 ℃ and 25 ℃, environment relative humidity can master is about 60%. Base paper should pay attention to when using advanced use first, if the base paper moisture content is too high, can be placed longer before put into use, it is advantageous to the moisture loss, improve the quality of cardboard processing. On light is a commonly used packaging products post-press processing technology, the product surface after use cartons waterproof light oil glazing coating, can make prints enhanced resistance to water, fast, the friction and resistance to pollution, such as performance, but also can improve the product surface brightness, make the grade of the product is greatly increased. The characteristics of different glazing coating, product surface processing craft effect also to have certain differences. The same waterproof cartons are specular light oil, because of different material properties, formulation, its gloss effect, wear resistance and so on also differ. With a waterproof cartons of dumb light of light oil glazing, almost no printing quality of the surface gloss, but also had the water proofing property and abrasion resistance and so on. Highlights of the cartons waterproof light oil and waterproof cartons of dumb light of light oil, must has a good waterproof, abrasion resistance, to protect the surface of the printing quality.
