The top 5 problems occur during perforation testing with solutions

One of the important parameters of packaging is its perforation strength. Packaging materials like sachets, pouches, or other related materials have small holes that make them separate from each other. These small holes are called perforations and allow the customers to open the package easily. But do you know that if these perforations are weak then it could lead to messing as the items can get damaged while transportation or rough handling? Testing the perforation strength of packaging materials is one of the important parameters of quality control in the packaging industry. Being the leader of lab testing instruments, we at Presto provide you with a high-quality perforation strength tester that will help you to quantify the perforation strength of materials like pouches, thermoplastic films, and many more. 

Therefore, you can easily make use of this perforation strength tester to conduct the perforation test on the packaging materials with ease. This test will be carried out when the packaging material will be placed on this testing instrument and force will be required to separate the sachets with ease.
 
While conducting the perforation test on the materials, many manufacturers will face some issues whether it's related to unexpected reading or unusual noise in the machine. Therefore, we are going to discuss the top 5 issues related to the perforation test and how you can easily solve it. So, let us get started!
 

What are perforations and how you can easily test them?

A perforation is a small hole or row of holes punched into a material especially the packaging materials, so a part of it can be easily torn off. The purpose of perforation is to make the material easy to tear or bend. Perforations are commonly found on paper, pouches, thermoplastic films, and other packaging products.
 
They are often used to create coupons, tearing strips, or other removable parts. The size and spacing of these holes will vary depending on the intended use of the perforated material. When choosing a perforation pattern, it is important to consider the type of material being used and the amount of force required to tear it. Otherwise, the perforation may not function as intended. Testing the perforation strength of packaging material is an important part of the quality control process and thus, you can easily test the perforations of the material with the help of the Presto perforation strength tester.
 
This lab testing equipment plays a significant role in the packaging industry. You can read about the use of perforation testers in the packaging industry here.
 
To test the perforations of the material, you can easily follow the steps mentioned below:
 
  • Start the machine by plugging in it 5 amp, 220 Volts AC and place the specimen on it. Once you turn on the machine then you should prepare the specimen first and then place it. You can read about how you can prepare and place the specimen using the Presto perforation strength tester.
  • Once the specimen will be placed and prepared then you can press RESET and TARE to set the value at the peak load indicator to zero.
  • After setting the zero on the load indicator, turn the rotary switch to the down direction. This will move the lower grip in the lower direction. On the movement of the lower grip in the lower direction, there will be an increase in the values shown on the load indicator.
  • Now turn the rotary switch to the off position after the specimen has been tested for perforation.
  • Once the machine stops, the display showing load will return to zero and the green display will freeze.
  • Press the Memory switch on the load indicator to show the peak value.
  • Note down the values displayed on the load indicator.
In this way, you can easily commence the test using the Presto perforation strength tester. You can easily read about the role of perforation strength tester in the packaging industry. Now, let us discuss the top 5 problems that will occur while performing the perforation strength test.
 

Problems people faced by performing perforation strength test
