Glass paper production process

Abstract

The invention discloses a glass paper production process which comprises the following steps of (1), extracting; (2), repulping; (3), carrying out ultrasonic treatment; (4), floating; (5), washing; (6), preparing an adhesive; (7), carrying out a film production procedure; and (8), carrying out a forming procedure. The glass paper production process is reasonable in process, and environment-friendly and practical in raw materials; resources are fully utilized, the process cost is lower; the pollutant emission is less, and most importantly, the paper quality is improved; the paper package is more environment-friendly and economic. The glass paper production process is suitable for being popularized and used in the paper package industry.

Description

[0001] technical field [0002] The invention relates to a packaging production process, in particular to a cellophane production process. Background technique [0003] Cellophane is mainly used for packaging goods. The original plastic film was found to be cellophane, which is obtained after extracting cellulose from wood. Cellophane is rich in color and light in weight. Now cellophane has been widely used in furniture decoration, food, shirts, and cigarettes. , Cosmetics and other supplies, but cellophane needs to consume a lot of wood fiber, which requires high purity of wood fiber. At present, many waste papers cannot meet the requirements, and a large amount of ink is difficult to remove, so that the cost of cellophane is very high, and it cannot be widely produced. . The application number is CN200910164306.X, which discloses a production process of cellophane. It uses waste cellophane as the main raw material, dries it and LiCl separately, and then immerses the waste...

[0003] Cellophane is mainly used for packaging goods. The original plastic film was found to be cellophane, which is obtained after extracting cellulose from wood. Cellophane is rich in color and light in weight. Now cellophane has been widely used in furniture decoration, food, shirts, and cigarettes. , Cosmetics and other supplies, but cellophane needs to consume a lot of wood fiber, which requires high purity of wood fiber. At present, many waste papers cannot meet the requirements, and a large amount of ink is difficult to remove, so that the cost of cellophane is very high, and it cannot be widely produced.

The application number is CN200910164306.X, which discloses a production process of cellophane. It uses waste cellophane as the main raw material, dries it and LiCl separately, and then immerses the waste cellophane in a solution composed of potassium permanganate and solvent DMAc for heating activation. Make it dissolve, and finally produce cellophane according to the conventional method, not only the discarded cellophane can be reused, the resources can be fully utilized, and the obtained cellophane mixed solution has better stability, but the raw materials selected by this process are relatively limited, and the waste cannot be reused. Paper resources are fully utilized, and the chemicals used in this process are relatively expensive, which makes the process cost high and difficult to promote, and needs to be further strengthened and improved
