No Dark&Protruding Impurities Carbonless Paper  

 

 

Introduction

The base paper used for carbonless paper coating has stricter quality and quantitative requirements than other coated base papers, mainly as follows:

Must have a certain degree of softness and stiffness, in order to facilitate replication; Can have a good separation of the color layer and the microcapsule layer; It has good smoothness and gloss; It has good dry and wet strength, and has good wet deformation; There should be no dark dust and protruding impurities; Its PH should be close to neutral.

Related quality requirements for carbonless paper base paper:

1 Quantification

Carbonless paper is developed by force, and the pressure is proportional to the number of color layers. Under normal circumstances, 40 g/m2 base paper is used, and the number of color layers is 5-7 layers.

The quantitative deviation of the banner of the base paper is generally controlled at 0.5% to suit the coating processing requirements.

2 Intensity

For low-speed coating below 100 m/min, the crack length of the base paper is higher than 3600 m; for the coating speed of 200 m/min or more, the crack length of the base paper is higher than 4000 m.

3 Smoothness

Due to the smoothness of the paper, especially the smoothness of the back surface, the effective distribution of the material to be coated is determined, so the smoothness of both sides has a great influence on the color development effect of the paper.

Generally, the frontal smoothness is greater than 60 s, and the difference between the two faces cannot be greater than 20%.

4 Deformation:

Because the carbonless paper uses different materials and is applied to different layers of the paper, the paper will be deformed during the printing process, so the fiber ratio of the base paper should be reasonable.

 

Classification

Carbonless paper can be divided into rolls and sheets according to specifications.
