How to prepare and place specimens for the Presto perforation tester?

Perforations are tiny holes that we see in different numbers of materials including packed items, food packets, sachets, etc. These tiny holes make it easy for the customer to use the packaging materials efficiently. What if these perforations are easily separated? It will lead to poor quality of the product. Thus, testing it is a necessary part of product quality control. Therefore, we at Presto have come up with one of the widely used lab testing instruments in the packaging industry known as the perforation strength tester. This quality lab testing equipment will help to quantify the perforation strength or tensile ability of materials like pouches, thermoplastic films, paper, and packaging materials.

 This perforation strength testing instrument is based on a microprocessor-based display to accurately view the testing results. It works on the constant rate of elongation principle and will help you to display the perforation strength of materials with ease. Here in this article, we are going to provide you the information about how you can easily prepare and place the specimen for the Presto perforation strength tester. So, let us get started!

What is the perforation strength of the materials?

Perforations are an important factor to consider when packaging materials. A poor perforation strength can easily separate packets, while a strong perforation can make it more difficult to open the packet. This can be a problem when packaging materials that are delicate or need to be kept together in a certain order. This is where the Presto perforation strength tester comes in handy. By ensuring that the perforation strength is just right, you can be sure that your packaging will keep its contents safe and sound.
This lab testing instrument will help you to appropriately test the perforation strength of your packaging material so that your customers will not find any issues while separating your products from one another. This ideal testing instrument will generate a high force that can separate the packets and pouches from each other. It comes with a limit switch as well that will serve as a safety element to restrict the movement of grips.
Thus, you can easily determine the perforation strength of pouches with ease. Below we have listed the features and technical specifications of this lab testing equipment.

Features of Presto perforation strength tester

In the packaging industry, perforations are used to create a hole in the packaging material so that it can be easily opened. However, these perforations need to be strong in order to avoid these packaging problems. Thus, we at Presto perforation strength tester, it will be easy for you to test the perforation strength of pouches with ease. This testing instrument also plays a significant role in the packaging industry.
Below we have listed the features of this testing equipment.
  • Microprocessor-based display for accurate test results
  • Works on Constant Rate of Elongation (CRE) Principle
  • Display for Perforation strength of test specimen
  • Highly accurate test results under elongation/tensile force
  • Strong gripping clamps to perform the test at 180 degrees.
  • Bright LED display
  • Inbuilt calibration facility

With these high-quality features, it will be easy for you to determine the perforation strength of materials. You can easily test the perforation strength of pouches using tensile forces. Now, we will discuss how you can prepare and place specimens accurately on the perforation strength tester.

Steps to prepare & place specimen using perforation strength tester

  • You can easily prepare the perforation strength of the packaging material by taking two sachets to perform the perforation test.
  • To place the specimen accurately, you need to place 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 a 900 angle with respect to the upper grip.
In this way, you can easily prepare and place the specimen for performing perforation tests.
