The goal of perforation is to introduce holes with small diameters into various materials in a controlled manner and with precise placement. This perforation can serve various purposes. Obvious applications include tear edges, optical elements in paper or cardboard packaging, or opening perforations (Easy Opening) for packages.
Today, laser perforation is very frequently used when it comes to creating targeted ventilation - such as with packaging for fresh food, in cigarettes, or in membranes.
Laser perforation has many advantages over other methods, for example:
Laser microperforation technology, known for its precision, high speed, and cost-efficiency, is increasingly favored across various industries. By eliminating the need for traditional tooling and reducing changeover times, it provides versatile solutions for modern manufacturing challenges. Here are some perforation applications where laser technology is already making a significant difference.
Extending Freshness: Laser perforation is integral in creating controlled ventilation for packaging films, a process essential for prolonging the shelf life of perishables like fruits, vegetables, and cut flowers. By adjusting the gas composition within the packaging, products stay fresh for longer, reducing waste and enhancing consumer satisfaction. This is referred to as MAP or Breathable Packaging
Enhanced User Experience: The precision of laser perforation allows for the design of easy-open packaging, a feature highly valued in the food sector and by FMCG providers. This technology improves product accessibility and convenience, offering a more user-friendly experience for consumers.
Regulated Filtration: In the tobacco industry, microperforation is employed to maintain compliance with health regulations. It precisely controls the air-to-smoke ratio by adjusting filter ventilation, thereby helping to limit the inhalation of harmful substances. This precision is applicable during both the tipping paper production and the cigarette manufacturing stages.
Regulated ventilation: Many industrial processes require controlled ventilation. From automotive parts and filter media to electronic components, cat litter bags and frozen food packaging, for example - the applications for laser microperforation are many and varied.
These applications showcase the adaptability and efficiency of laser perforation technology in responding to diverse industrial needs. From preserving the freshness of food to ensuring product compliance with health standards, laser perforation is a pivotal innovation in modern manufacturing practices, promising enhanced quality, consumer satisfaction, and operational efficiency.
Laser perforation is versatile, effectively handling a range of materials including mono- and composite films (such as OPP, PE, PE-LD, PET, PP, CPP, EVA, PLA), along with paper and kraft paper. Its ability to achieve exceptionally high speeds makes it ideal for web and roll materials that require rapid processing.
