Laser perforation technology represents a cutting-edge solution for creating precise perforations in a variety of materials. It is applied through a wide range of industries and applications. Depending on the size of the applied holes it is sometimes also referred to as laser micro perforation. In this article you learn the advantages, possible applications and considerations for its use from the industry leader for laser perforation machines.
The purpose of laser perforation is to insert small-diameter holes into various materials in a controlled and precise manner. The reasons for doing this can vary widely. Common uses include creating tear-off perforations, adding visual features to paper or cardboard packaging, or incorporating easy-open features in packaging designs.
Laser perforation has become a popular method for achieving precise ventilation, especially in applications like packaging for fresh produce, cigarettes, or in the design of membranes, where controlled air flow is crucial. More details on possible applications will follow in the application section.
Laser perforation offers several key advantages over traditional mechanical perforation methods:
Laser perforation stands out as a compelling alternative to traditional perforation methods due to its high flexibility, absence of tooling costs and changeover times, and the capability to achieve top speeds. Below are examples of applications where our machines have been successfully utilized.
MAP packaging is essential for fresh produce like fruits and vegetables. Laser perforation allows for controlled ventilation within the packaging, significantly extending the shelf life of the contents.
Easy-open features are crucial for enhancing consumer experience for a wide range of food and luxury goods manufacturers, as well as Fast-Moving Consumer Goods (FMCG) providers. Laser perforation offers a flexible and precise solution for implementing these features.
Laser perforation ensures compliance with legal limits for modern filter cigarettes, which might not be achievable without such precise perforation. It prevents the inhalation of more harmful substances than allowed by regulations.
The perforation can be applied either during the cigarette paper manufacturing process or on the finished cigarette itself.
Laser perforation technology is versatile and adaptable, capable of processing a wide array of materials. This includes both single-layer and laminate materials such as oriented polypropylene (OPP), polyethylene (PE), low-density polyethylene (PE-LD), polyethylene terephthalate (PET), polypropylene (PP), cast polypropylene (CPP), ethylene-vinyl acetate (EVA), and polylactic acid (PLA).
Additionally, paper and kraft paper are also well-suited for laser perforation. The technology's ability to achieve exceptionally high speeds makes it particularly beneficial for handling web and roll materials, which are typically processed at high velocities.
Plastics, foils, laminates
Metals, metal foils, metal composites
Other materials
This capability is particularly beneficial in applications requiring not just functionality but also aesthetic appeal, such as in packaging, textiles, and various industrial and consumer products. The versatility and precision of laser perforation make it an ideal solution for projects that require detailed and complex perforation patterns.
