Varnish film laminating film on the anatomical definition of the total after ligament extends upward from the rear of the joint cover, called film bags, the joints and spinal cord separated. The film company decoration cabinet decorative plates on the surface of the double-sided, with PVC film, use double-sided laminating machine for decorative plate surface modification coating process is also known. Mainly as a composite finished after cutting, showing the direction of the film curl, can not remain flat state. Severe automatically curled into a cylindrical shape. The main reason: ① being coated paper thin; ② paper moisture, humidity; ③ low temperature; ④ loose paper flatness poor; ⑤ When laminating pressure, high temperature, long time. Development can be described as kraft paper shopping bag brainchild custom composite woven floor, load-bearing capacity of materials to improve it continuously enhance the appearance of fine paper and plastic film becomes increasingly woven manufacturers of various trademarks, logos and India system in the brown paper bag, into the streets of the store among the shops. Until the mid-20th century, emerged as plastic shopping bags shopping bags in the history of the development of another large-scale revolution. It slimmer, stronger and cheaper manufacturing cost advantages make once eclipsed glory of the brown paper bag. Colloid further dissolve slowly, resulting in the loss of a viscous colloid, the paper and plastic film from, that is blistering. Actual work has been tested A printed divided into two groups, one group pre-treatment film, another group without pretreatment, and then coated under the same conditions, after a period of time to observe proof paper-plastic composite bags, was found after treatment is not blistering, no handling easier blistering. So be sure to pre-treatment, let the ink layer inside the various solvent evaporation clean as soon as possible, so as to ensure the firmness of its permanent adhesion strength.
