Model HN200 HOT MICRO PERFORATION system for holes from 200µ to 2mm with motorized needle roller of Ø200mm
-
This system is designed to make "hot" micro holes on moving films of various materials and thicknesses and is to be installed as a host unit in film transport lines, such as slitters, extruders, printing and welding machines. The HN 200 guarantees perfect micro holes on mono- or bi-oriented materials and even with low heat input; it is ideal for delicate processing on shrinkable material or with very high needle density per cm2..
-
The HN200 is an electrically heated needle microperforator. The running film arrives at the device and is perforated by the motorized needle shaft that is approached by the contrast roller designed to support the material. The micro-perforation is achieved by melting and perforating the material, caused by the needles fixed on the interchangeable bronze sleeves. The needle sleeves are mounted on the needle shaft placed inside an insulated chamber and brought to an adequate temperature by the group of infrared lamps.

A short introduction: What is Hot Needle Perforation?
Hot needle micro-perforation utilizes heated needles to melt precise apertures into flexible films and laminates. Unlike mechanical punching, this thermal process cauterizes the hole edges, creating a reinforced rim that prevents tearing and preserves material strength during high-speed conversion. It offers total control over permeability, making it the ideal solution for moisture regulation and breathable packaging (MAP) across the food, medical, and industrial sectors.
How Do Hot Needle Perforation Machines Work?
Hot Needle Perforation machines use a precise thermal-mechanical process to create micro-holes in flexible materials such as plastic films. This process enhances breathability, shelf life, or user interaction (e.g., easy-open packaging), while maintaining the structural integrity of the material. Here’s a step-by-step breakdown of the technical principle behind these machines:
-
The film or material is unwound from a roll and guided through the machine using tension-controlled rollers.
Consistent tension ensures smooth movement and accurate perforation.
-
Stainless steel or alloy needles are mounted on a rotating drum or linear array.
These needles are electrically heated to a controlled temperature, usually between 200°C and 400°C, depending on the material type and thickness.
-
As the film moves past the heated needle array, the needles briefly and precisely contact the surface.
The heat melts the material upon contact, creating clean, round micro-holes without tearing or pushing the material.
-
The melted material around the hole self-seals, forming smooth, reinforced edges.
This prevents hole enlargement or tearing during further processing or use.
-
The perforated film is wound onto a finished roll, ready for downstream processing such as printing, laminating, or bag-making.
Advantages of Hot Needle Perforation
-
The heat from the needles melts the film during perforation, creating smooth, sealed edges that prevent tearing and reduce the risk of material degradation over time.
-
Electrically heated needles and synchronized film movement ensure uniform hole size, spacing, and alignment across the entire web—critical for quality-sensitive applications.
-
Unlike mechanical punching, hot needle perforation doesn’t introduce stress fractures. The sealed edges preserve the structural integrity of the film, even under tension or heat sealing.
-
Compared to cold punching or laser perforation, hot needle systems are generally more energy-efficient, better at preserving film strength, and simpler to maintain—especially when sealing quality and mechanical durability are key requirements.
