Do You Know about Paper Tester

In order to meet the quality testing needs of paper and cardboard products, there are currently several types of paper packaging testing instruments

1. Instrument for detecting the basic properties of paper and cardboard

This includes detection instruments for quantitative, thickness, tightness, moisture, absorption and other properties, which are the most commonly used basic instruments. There are more than ten types of instruments in this category, including digital quantitative measuring instruments, manual thickness measuring instruments, electric thickness measuring instruments, high-precision thickness tightness measuring instruments, manual corrugated cardboard thickness measuring instruments, electric corrugated cardboard thickness measuring instruments, digital display corrugated cardboard thickness measuring instruments, variable pressure thickness measuring instruments, general moisture measuring instruments, fast moisture measuring instruments, simple absorption measuring instruments, flip absorption measuring instruments, absorption height measuring instruments, etc. These varieties can basically meet practical needs.

2. Paper and cardboard strength performance testing instrument

Strength performance refers to physical properties, including tensile strength, compressive strength, burst strength, puncture strength, tear strength, bending strength, folding fatigue strength, short-range compression strength, and internal bonding strength. These physical tests are the dominant instruments for testing the strength performance of paper and cardboard. This type of instrument includes: constant speed loading method pendulum type tensile testing machine (with four types and specifications), constant speed stretching method electronic tensile testing machine (with more than ten types and specifications), cardboard compression testing machine (with multiple structures), cardboard compression testing machine (with three specifications and multiple structures), paper burst strength tester, cardboard burst strength tester, number display puncture tester, Taber type stiffness tester, number display Taber stiffness tester, MIT flexural resistance tester, Schober type flexural resistance tester, multi pendulum tearing resistance tester, digital display tearing resistance tester, short distance compression tester, and more than thirty other varieties. This is the leading product and foundation of paper packaging testing instruments.

3. Testing instruments for special properties of paper and cardboard

In this category, there are specific testing instruments for properties such as breathability, wear resistance, brightness, glossiness, and chromaticity, which are very important for certain high-end paper and cardboard. This type of instrument includes Schopenhauer's breathability meter, Gray's breathability meter, wear resistance tester, whiteness meter, glossiness meter, etc. Among them, whiteness meter, glossiness meter, and Schopenhauer's breathability meter have been produced for many years.

4. Paper and cardboard performance testing auxiliary instruments, tools, and various punching and cutting tools

This is an essential auxiliary equipment for ensuring the quality of paper and cardboard performance testing. This type of equipment includes more than ten varieties, such as corrugated paper vertical fluter, pulp dryer, standard sampler, adjustable distance sampler, quantitative test sampler, corrugated cardboard edge press, flat press, adhesive strength sampler, paper and cardboard tensile, ring press, stiffness, tear test special punching and cutting device, and various special supporting instruments. At present, these auxiliary devices have been developed and produced domestically, which can greatly meet the needs of customers.

5. Paper pulp and slurry testing instruments

This type of instrument should be strictly classified as small-scale laboratory equipment. Currently, only a small number of varieties such as Schopenhauer type beating degree meter (beating degree meter), Canadian free degree meter, Dutch 23 liter small beating machine, and simple paper forming machine can be produced in China.
