轻量纸是薄的, 包装常用的软纸, 印刷和书写. Because of its special paper structure and properties.

检测性能
Its detection needs to pay attention to the following main performance:

厚度和密度: The thickness and density of lightweight paper will directly affect its stability and use effect. 通过测量纸张厚度即可测量厚度和密度, 密度和基重.

Paper strength: Lightweight paper needs to have a certain strength to ensure stability and durability. 强度测试可以通过测量拉伸强度来进行, 撕裂强度, folding resistance and other indicators.

Paper flexibility: Lightweight paper needs to be flexible to ensure its suitability for use in areas such as packaging and printing. Flexibility can be tested by measuring the number of folds and bending of the paper and other indicators.

平整度: Lightweight paper needs to have a certain flatness to ensure stability and printing effect during the printing process. 平整度可以通过测量纸张表面光滑度来测量, 羽高和板凸度等指标.

轻质纸的主要性能及测试方法

Wear resistance of paper: Lightweight paper needs to have certain wear resistance to ensure its durability and use effect. 耐磨性可以通过测量纸张的磨损程度和表面硬度来测试.

Air permeability of paper: Lightweight paper needs to have some air permeability to ensure that it is suitable for use in areas such as packaging. The air permeability test can be carried out by measuring the air permeability and water vapor permeability of the paper.

Printing performance of paper: Lightweight paper needs to have certain printing performance to ensure the printing quality of printed matter. The printing performance can be tested by measuring the paper’s water absorption, ink absorption, printing clarity, color reduction and resistance to printing pollution and other indicators.

Paper environmental protection: lightweight paper needs to meet environmental standards, 不含有害物质, 对环境无污染. 通过测量挥发性有机化合物可以检验环境保护, 重金属, 氯离子, 荧光增白剂及其他指标.

适用范围: Lightweight paper is used in a very wide range, different uses of lightweight paper need to have different performance requirements. The scope of application can be tested by measuring the applicable environment of paper, applicable packaging items, applicable printing technology and other indicators.

Machinability: Lightweight paper usually needs to be cut, folded, punched and other processing, so it needs to have a certain degree of machinability. The machinability can be tested by measuring the performance change and loss of paper in different processing processes.

The above performance indicators are the key content of light paper testing. 不同的使用要求和标准也会影响纸张的检测标准和方法.
