HOW TO: Identify What Perforation Method is Right for Your Application

Published: November 17, 2021

There are HOLES in many more places, performing important tasks than most of us realize. Papers, films, foils, foams, cardboards, nonwovens, composites and other materials can all be MACRO, MICRO or NANO PERFORATED for a wide range of reasons.

There are obvious applications, like the holes that allow air in bags to extend shelf life. In food packaging, the most common applications are packaging for pet foods, frozen foods, boil in bag, microwaveable packaging, lidding films, steam vents and easy tear openings. The applications are vast and endless.

How do I Know What Perforating Technique Will Work Best for my Project?

This question is literally the reason why we have become a one-stop shop for perforating solutions. We take the following simple steps to take you from concept to production:

1. Discuss the project and expected outcome
2. Study material and see which process works best to achieve your perforating goals
3. Determine hole size and pattern that is suitable
4. Run samples
5. Design tooling and machinery
6. Run toll perforating or
7. Install and setup perforation tooling or machinery in your facility.

Whether you are having issues with trapped air or liquid, looking to add grip, texture, extend the surface area of a material for increased absorbency of liquid or sound, our experience in the hole making arena will fast track you to where you need to be.

Perforating Technologies Available:

• Hot pin perforating (rotary and vertical);
• Cold pin perforating (rotary and vertical);
• Slit perforating (razor and crush);
• Tear line perforating (cross tear, inline tear, both or custom);
• Punch perforating (vertical cam, electro-pneumatic and electro-mechanical);
• Rotary punch perforating (ejection and suction);
• Laser perforating;
• Thermal (flame) perforating;
• Vacuum perforating; and
• Embossing.

No matter whether you have an extruder, laminator, flexo-printer, coating machine, slitter, center folder, bag making machinery or other process, perforating can be  added to your existing equipment as tooling, as an attachable unit, or can be offered as an offline process.

We are excited to introduce an expansion to our already diverse range of perforating solutions! Machine direction AND cross web direction slit perforating in one, compact unit.

Whether you want to add slit perforating capabilities to your existing machinery or, if you are looking for a drop-in unit to keep things simple, we can help.

Custom to your specifications, any length slit, any spacing.  Send your material to us for examination, and we can design a blade and pattern to suit your requirements.

Vent lines that double as easy-tear lines can be made continuously at a repeated distance, or in register after reading a color mark if you need the perforations in a particular location.

We have the perforating solution. Got holes?
