An analysis of the current domestic paper packaging testing instruments

The sustainable development of paper-making and packaging testing instruments and the development of related standards are inseparable. According to the statistics in the National Paper Industry Standardization System Catalog, there are about 360 kinds of paper products, and there are more than 160 related test method standards. There are 85 standards for mechanical performance test methods. In addition, more than 50 standard items for semi-finished and finished raw materials involving cartons are also available.
In order to meet the urgent need for quality inspection of paper and carton products, and to implement the relevant test method standards, papermaking packaging testing instruments currently require about 70 different specifications on the market. The responsibilities of the paper-making and packaging inspection instrument industry are the development and production of special instruments and various special appliances. The basic conditions of comprehensive paper-based packaging testing instruments are as follows:

First, paper and cardboard basic properties testing equipment

Second, paper and cardboard strength performance testing equipment

Strength performance refers to the physical properties, which include tensile strength, compressive strength, burst strength, puncture strength, tear strength, flexural strength, folding fatigue strength, short-range compression strength and internal bond strength, etc. Performance testing instruments, these physical tests are the dominant instruments for the detection of the strength properties of paper and board.

Third, paper and cardboard printability testing instruments, such as printing surface smoothness, roughness, surface strength and other testing equipment, is an important instrument for performance testing equipment, high technical requirements, manufacturing is more difficult. Can only rely on imports, which is the problem that the paper-making and packaging inspection instrument industry should redouble its efforts in the future, and is also the bottleneck of the current domestic market.

Fourth, paper and cardboard some special performance testing equipment

In this category, there are specific testing instruments such as breathability, abrasion resistance, brightness, gloss, chroma, etc. These special properties are very important for some advanced papers and high-grade paperboards.

Fifth, paper and board performance testing aids, instruments and various types of punching tools, which is the paper and paperboard performance testing process, to ensure the quality of the test is an indispensable important auxiliary equipment.

Sixth, papermaking pulp slurry testing equipment category, strict classification of such equipment should belong to a small laboratory equipment, so this type of equipment is also a weak link in the domestic testing equipment industry.
