Puncture Resistance Tester

If you are the one looking for the best testing equipment to determine the resistance to puncture of paper and paperboard, then we suggest you go with Presto puncture resistance tester. This is one of the amazing testing devices used to measure the resistance of paper, and other related products when they are subjected to puncture and determination of absorbed energy. The puncture resistance can be defined as the measurement of maximum energy or force required to penetrate an object. You can easily measure the puncture resistance of the object with the help of a Presto puncture resistance tester. It is one of the amazing testing instruments that will be used to determine the puncture resistance of paper and other packaging material. In the packaging industry, the puncture resistance of paper and packaging materials matters the most. The paper boards or corrugated boxes may get a force from the pointed corner of any object during transportation and handling. The same effect is emitted by the puncture-resistant testing instrument. The superior quality of a corrugated box replicates its superior resistance value.

Puncture resistance tester is a special packaging detection instrument for the determination of anti-puncture performance (namely puncture resistance) of Paper & Packaging materials. Resistance to puncture is an important parameter that determines the quality of a wide range of materials — from thin papers to thick boards and similar materials. The specimen is clamped on a fixture and is pierced with the help of a pendulum released from 90 Degree position. The pendulum head is made pointed in a pyramid shape. Different weights are provided in the pendulum for different scales. A pointer is fitted in the pendulum which gives the reading on a calibrated scale.

The corrugated box may get an impact from the sharp corner of any article during handling and transportation. The same effect is simulated by the puncture resistance testing machine. The higher the corrugated box quality the better its puncture resistance value.

The Digital Puncture Resistance Tester has been designed to determine the absorbed energy and the puncture resistance of cardboards and similar materials used for packing according to the standards: ISO 3036, TAPPI T-803, ASTM D 781. This tester measures the energy required to puncture containerboard or corrugated board with a pyramidal head affixed to a pendulum arm. Plastic films are strong and can be used in various packaging industries. Thus, you can easily measure the puncture resistance of plastic films with the help of a Presto puncture resistance tester. With the help of this easy-to-use testing instrument, you will get amazing results with the highest accuracy. The testing procedure is conducted as per the guidelines. The experts at Presto will provide you with full brief knowledge about how you can easily conduct the test with the help of this testing instrument.

While conducting this puncture resistance test, you need to take care of several factors. It includes the materials being used in the plastic films. The melt flow index of resins also has a deep impact on the puncture resistance of plastic films. The manufacturer needs to ensure that the resins they use in plastic or polymer manufacturing should have an optimum melt flow rate so as to provide the best value.

To start with the test, you need to prepare the sample first by taking four samples from the materials that you need to test. After that, you need to place the sample in the right way to accurately conduct the test. For this, you can open the locking pins from the specimen holding plate to separate both the plates from each other. Now place the sample on the lower plate by maintaining the center. Place the upper plate on the sample and clamp the locking pins by ensuring wrinkle-free sample placement. Once you prepare and properly place the specimen in the machine, then you can easily commence the test.

You can start the test by turning ON the machine by plugging the main socket of the machine into a 3 pin 5 amp socket. Switch on the MAIN button from the control panel. Apply the weight (R1/R2/R3) on the hammer and hang the hammer to its initial position. The R1, R2, and R3 weight as per the strength of the sample should be selected. The specimen should now be fixed between the clamps. Follow the below-mentioned steps to easily conduct the test:

• Press the CAL key to tare the previous value.
• Press the PAR key, select the energy scale R1/ R2 or R3 (as per requirement) using increment and decrement keys. You can also increase the R1, R2, and R3 values up to 3.
• After selecting the energy scale again press the PAR key to enter the thickness of the sample.
• Press the PAR key to execute the program. Press the CAL key to tare the previous value.
• Release the pendulum by pulling the pendulum releasing knob.
• After the puncture of the sample, the indicator shows the angle and the force in Joule/meter.
• Record the readings to measure the Puncture resistance strength of the sample.

In this way, you can easily conduct the puncture resistance test of the testing sample.
