Oct 13, 2017

Handaged paper bag of oil technology Description: portable paper bag on the process can improve the color of the paper bag color, while speeding up the ink drying speed. The paper bag is treated with a varnish coating, and the paper bag printing ink is protected by the paint, which reduces the amount of ink used in the daily use of the paper bag due to friction.

The paper is a paper bag surface decoration processing technology, it is in the paper bag surface coated with a layer of colorless and transparent material, after leveling, dry, calendering in the paper bag after the formation of thin and uniform transparent light Protective layer, in order to increase the printing paper bag ink wear resistance, played a protective role to prevent contamination of paper bags. At the same time portable paper bag oil can improve the surface of the paper bag gloss and color purity, improve the entire paper bag product visual effects.

Paper bag coating applications: 1. white cardboard bag if there is full of printed content on the need to use the coating process, so that the ink will not fade 2. copper paper bag if there is full of printed content on the need to use the coating process, so that ink does not Will fade 3. gray bottom white paper bag if there is full of printed content on the need to use the coating process, so that ink will not fade 4. Kraft paper because of its strong ink absorption capacity, you do not need to protect the ink to fade.

The coating process is a kind of surface processing technology after the printing of the bag, refers to the use of laminating machine in the surface of the portable paper bag covered with a layer of 0.012 ~ 0.020mm thick transparent plastic film and the formation of a paper-plastic processing technology, And was known as India after the plastic, printed after the plastic or postpress film.

After the bag printing process can be covered by the coating process is divided into two categories:

One: dry coating method

Dry coating method It is in the plastic film coated with a layer of adhesive, is currently the most commonly used coating method. Through the drying machine drying machine drying machine to remove the solvent in the adhesive and dry, in the hot state with the paper print adhesive film products.

Two: wet coating method

Wet laminating method is through the pressure roller and paper prints into a coating product, in the plastic film coated with a layer of adhesive. Water-based coating process and wet coating process has a simple operation, the amount of adhesive less, without damage to the environment of organic solvents, coated printing with high strength, high grade, easy to recover and so on.
