Lekki papier jest cienki, miękki papier powszechnie używany do pakowania, drukowanie i pisanie. Because of its special paper structure and properties.

Wydajność wykrywania
Its detection needs to pay attention to the following main performance:

Grubość i gęstość: The thickness and density of lightweight paper will directly affect its stability and use effect. The thickness and density can be measured by measuring paper thickness, density and base weight.

Siła papieru: Lightweight paper needs to have a certain strength to ensure stability and durability. Badanie wytrzymałości można przeprowadzić poprzez pomiar wytrzymałości na rozciąganie, siła rozdarcia, 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.

Flatness: Lightweight paper needs to have a certain flatness to ensure stability and printing effect during the printing process. Flatness can be measured by measuring paper surface smoothness, feather height and board convexity and other indicators.

Główne właściwości i metody badania papieru lekkiego

Wear resistance of paper: Lightweight paper needs to have certain wear resistance to ensure its durability and use effect. The wear resistance can be tested by measuring the wear degree and surface hardness of the paper.

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, klarowność druku, color reduction and resistance to printing pollution and other indicators.

Paper environmental protection: lightweight paper needs to meet environmental standards, nie zawiera szkodliwych substancji, brak zanieczyszczeń dla środowiska. Ochronę środowiska można sprawdzić mierząc lotne związki organiczne, metale ciężkie, jony chlorkowe, fluorescencyjne rozjaśniacze i inne wskaźniki.

Szereg zastosowań: 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, fałdowy, 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. Różne wymagania i standardy użytkowania będą miały również wpływ na standardy i metody testowania papieru.
