Important Facts about Perforations in Paper Products

November 30, 2020

One element that is prominent to the production of a lot of paper products is perforations. Perforations are a row of tiny holes that are normally punched on paper products. These holes allow sheets of paper to be separated from one another just by folding and tearing along the dotted line. Without perforations, paper sheets would require other cutting tools just to separate them.

Due to the convenience that they bring, perforations can also be found on plastics and packaging products. They have helped many materials to be torn and bent apart without requiring scissors or cutters. They have also provided many benefits to a wide variety of applications.

Primary Processes in Making Perforations

Perforated lines are normally created out of special cutting tools that can help create vertical cuts along with the backing of a specific material. These cutting tools have a wide variety of selection, with each possessing different cut sizes, depth edges, and other elements. They can also be made from different high-quality metals, ensuring that the cutting process can be done precisely and optimally.

One system of measurement that is used in measuring perforation rates is teeth per inch (TPI). It basically describes the number of perforations that will or have already punched into a material. A material with more holes allows its parts to be separated more easily. The die-cutting process for perforations is expected to be fast, efficient, and precise. 

Benefits of Perforations in Paper Products

Perforations have been utilised in the industry of paper manufacturing and packaging since they bring a lot of useful benefits. Some of the benefits of perforations are as follows:

  • Clean Tearing: As previously stated, perforations allow paper products to be separated without the need for cutting accessories. Hence, paper products that consist of labels, designs, and others can be torn apart easily and properly. The chances of obtaining irregular or inconsistent cuts are minimised with the presence of perforated lines. 
  • Easy Storage:Compared to storing a pile of individual sheets of paper, paper products that have perforations can be easily stored and preserved without the risk of ruining their overall quality. The perforated lines will not get destroyed even if the paper products will be stored for a long time. Alternatively, storing a pile of individual paper sheets can be a headache as time passes by.
  • Versatility: Another great benefit of perforations in paper products is that they are versatile. Almost all types of paper materials can be easily punched with tiny holes. Even some packaging materials now opt for perforations due to the convenience they can bring.

Various Applications of Perforated Lines

Given these benefits, perforated lines are now mostly integrated into numerous paper and packaging products. Some of the products that utilise and possess perforations are trash bag rolls, bubble wrap rolls, boxes for food packaging, tear off boxes for product display, and wine boxes. Other instances where perforated lines are used include movie or raffle tickets, coupons, gift certificates, scrapbook add-ons, stamps, brochures, notebooks, business cards, paper towels, and toilet paper.
