Perforation Tester

If you are looking for a consistent tool to quantify the perforation of the strength of packaging material then we suggest you go with Presto perforation tester. This is one of the amazing testing instruments that will help you determine the tensile ability of perforated materials. Those who work in the packaging industry must have knowledge about perforation. Perforation in packaging is the process of introducing small holes at the end of the packaging of two products to separate them easily. The perforation tester is a testing instrument that is used to determine the minimum amount of force that is required to separate two different packets from the perforated area. The Presto’s Perforation tester is an ideal testing instrument that is used in packaging industries for testing the strength of the perforations applied on various packaging materials.

To test the perforation of two sachets, a Perforation test is performed. This test can be carried out with the help of a testing instrument known as a Perforation tester. Presto’s perforation tester is widely used in the paper & packaging industry to test the strength and elongation of thermoplastics films and packets to determine the force requires to separate two sachets from the perforated area. The instrument work on the principle method that measures the force needed to perforate a film or a packet using tensile forces.

The Perforation Tester is mainly used in industries and industrial laboratories to test the strength and elongation of thermoplastic films and packets to determine the force requires to separate two sachets from the perforated area. The instrument is meant for creating high forces that are further used for various testing and analysis. The instrument is provided with a limit switch which acts as a safety feature for the machine and limits the movement of grips of the machine. The out body of the machine is fabricated with mild steel which is duly powder coated. There is a digital peak load indicator provided with the instrument for a digital readout of the test results. The limit switch provided with the instrument is one of the best safety features that prevent the clashing of the grips.

The Presto perforation tester has high testing range provided that is of 50 kgf and 100 kgf. This testing instrument also contains big type clamping grips for firm gripping of the test specimen. Thus you can easily place the specimen and test them without worrying about slippage. You can easily place two sachets in the perforation test and assess their strength and elongations. When you make use of this testing instrument, then you can evaluate the results and compare them with the conventional test.

To perform this test effectively, you can start the machine by plugging it into the 5 amp, 220 Volts AC plug. After that, turn this testing machine ON. After the machine turns ON, then you need to place the one end of the sachet between the upper fixed grips and tighten the grip firmly. Now bring the lower movable grip upwards using a rotary switch so that the specimen can easily reach the grips. Ensure that the lower limit switch ring is placed at a position that keeps a minimum distance of 25 mm. Now place the lower end of the sachet strip between the lower grips and tighten the grip firmly. Ensure that the specimen should be placed in such a way that it makes 900 angels with respect to upper grip. Once you follow all the above-mentioned steps, then you can easily commence the test. The manufacturers of the packaging industry, make use of this testing instrument to test the value of perforation force that is required to separate the two sachets with holes provided. It is a highly effective solution that makes the use of minimum strength to separate the products from perforated areas.
