Detailed introduction:

What are the testing items for watermarked cartons?


Watermarked cartons are widely used in the outer packaging of commodities due to their characteristics and environmental protection advantages, and play an important protective role in the transportation, preservation and sales of commodities. During use, the carton is required to achieve firmness and durability.


At present, the fierce market competition makes the carton manufacturers continue to improve the production process and management to obtain great profits, which makes the carton users encounter more or less quality problems in the process of using the carton, such as The collapse and rupture of cartons after stacking caused many unnecessary losses.


In order to avoid such a situation and produce qualified carton products, it is necessary to test the corrugated box, so that the production process of the corrugated box can be effectively controlled. Therefore, it is of great significance to correctly understand and understand the testing items and testing methods of watermarked cartons.


1. Overview of appearance quality

Qualified cartons require clear printed patterns and handwriting, no broken lines and missing patterns, the same pattern chromaticity, bright and bright, and small printing position error. It is also required that the box body joints are standardized, the edges are neat, and the corners are not overlapped.


2. Moisture content

The so-called moisture content refers to the moisture content in the corrugated base paper or cardboard. It is expressed as a percentage. The moisture content has a great influence on the strength of the carton box.

Corrugated base paper has the properties of pressure resistance, tensile resistance, puncture resistance and folding resistance. If the moisture content is too high, the paper will appear soft, poor stiffness, and poor corrugation and bonding quality. If the moisture content is too low, the paper will be too brittle, easily broken when corrugated, and the folding resistance will be poor.


3. Cardboard thickness

The thickness of corrugated cardboard refers to the vertical distance between the upper and lower sides of the corrugated cardboard under pressure, in millimeters.
