The mechanical paper tearing tester is used to determine the tear strength of paper and cardboard materials, evaluating their resistance to tearing. It employs a mechanical pointer mechanism, with a measuring range of (10~1000) mN and a tearing force arm of (104±1) mm. Tear strength testers are widely used in the papermaking industry, packaging industry, and laboratory research.
Mechanical pointer mechanism, clear dial
- The curved section of the tearing tester features a dial to display the measured value and indicate the unit of tear strength.
- The paper tearing strength tester is equipped with an adjustable force application mechanism, which applies force through a mechanical device to gradually tear the paper until the paper tear strength test is complete.
- Using the dial, the operator can read the energy consumed during the mechanical pointer's descent, thus determining the tear strength of the paper or cardboard.
Stable base, wide application
- The base of the tear tester machine for paper provides stable support, ensuring that the equipment does not shift during the entire paper tear strength test process. The base is made of sturdy material to prevent vibration or displacement during testing, maintaining the accuracy of the tear resistance test results.
- The design of the paper tear strength tester is suitable for quality control during mass production of paper and can be applied to various types of paper, including newsprint, packaging paper, and cardboard of different thicknesses.
Application
Paper tearing strength testers are widely used in the quality control and performance evaluation of paper and cardboard. They are primarily used to determine the maximum energy or force that a paper material can withstand during tear resistance test, and are commonly found in paper product manufacturing, packaging industries, papermaking, and laboratory research.

Paper Tearing Strength Tester Instruction.pdfQ1: What is a paper tear strength tester?
A1: A paper tearing strength tester is an instrument specifically used to measure the tear strength of paper and cardboard materials. It simulates the tearing situations that paper may encounter in actual use, evaluating the paper's tear resistance performance. It is widely used in the papermaking, packaging, and printing industries.
Q2: What is the working principle of a paper tear strength tester?
A2: The paper tear tester machine clamps the paper sample between a fixed clamp and a movable clamp. A pendulum is released to generate a tearing force, and the energy consumed or the maximum force required during the tearing process is recorded. The tear testing machine typically displays the tear strength value on a dial or digital display, thus quantifying the paper's tear resistance.
Q3: What is the function of a paper tear strength tester?
A3: This paper tearing strength tester provides data support for quality control of paper and paper products, ensuring their reliability and durability during use. By testing the tear strength of the material, the tearing tester helps manufacturers understand the tearing or damage situations that paper may face in actual use. This is especially important for the packaging industry, allowing them to optimize the tear performance of the paper by adjusting raw materials or processes.
Tips: How to maintain a paper tear strength tester?
- After each use, clean the clamps, pendulum, and sample fixing parts to prevent the accumulation of paper scraps, dust, or oil that could affect measurement accuracy. Regularly check the pendulum, clamps, transmission mechanism, and screws for looseness or wear, and tighten or replace them as necessary.
- Keep the tearing tester for paper in a dry, temperature-stable environment. Avoid direct sunlight or humid environments to prevent mechanical deformation or damage to electronic components.
- Handle the paper tearing strength tester with care during operation to avoid excessive impact or misoperation that could damage the pendulum. Record each use and maintenance session for long-term management and tracking.
