How the PerfoTec Multi Head Laser System Optimizes Production Lines for Film Converters

Introducing Laser Systems to the film production line often raises concerns about reduced throughput. In the film converting industry, where profitability relies on the smooth, uninterrupted operation of slitter-rewinders, any downtime is simply unacceptable.

At the same time, the market forces converters to escape price wars in standard materials. The growing demand for Modified Atmosphere Packaging (MAP) and pre-perforated films drives the converters’ need for advanced, reliable inline microperforation solutions. The Multi Head Laser System from PerfoTec meets these needs, increasing the market value of the final product with guaranteed reliability at full production speed without slowing down the entire production process.

How exactly does this technology translate into tangible benefits for film converters and financial results?

Web Speed Variation and Material Waste Reduction

The biggest challenge with mechanical perforation and older laser systems is the loss of precision during the acceleration and deceleration of the film web on the slitter-rewinder. For the converter, this means concrete losses — uneven or deformed holes turn entire kilometers of film into defective production scrap, lowering the profitability of the order.

PerfoTec eliminates this risk using a patented control system with a built-in camera:

• Zero speed-related scrap - The system automatically adjusts the laser power to the current rewinding speed. Whether the machine is running at full speed or decelerating, every single hole maintains its targeted size and form.
• Quality guarantee for the customer - The converter gains peace of mind that every film roll produced meets strict Oxygen Transmission Rate (OTR) standards, minimizing the risk of costly claims from packers.

Higher Throughput Through PerfoTec Multi Head Laser System

Traditional single-head laser systems can act as a bottleneck depending on customer orders, as they often require rewinding the film multiple times or drastically reducing the line speed to cover a wide roll with the necessary number of laser microperforations.

The layout of the PerfoTec Multi Head Laser System solves this problem by allowing the installation of multiple heads operating simultaneously.

• Reduced processing time - Laser heads distributed across the entire width of the web allow for multiple lines of microperforation simultaneously in just a single pass. This directly increases the production volume on the same machine. If desired, multiple laser programs can be run simultaneously.
• Instant changeovers - The control software enables rapid switching between perforation patterns if desired, drastically minimizing downtime between different production batches.

New Markets and Higher Product Margins

For a film converter, implementing a precision laser means transitioning from a standard raw material supplier to a technology partner in the agricultural and food packaging sector.

Instead of competing solely over fractions of a cent per kilogram of barrier film, the manufacturer can offer high-margin solutions tailored to the specific physiological requirements of fresh produce. Precision micro perforation opens the door for securing contracts with packers of fresh produce.

Seamless Integration with No Hidden Costs

Investing in the PerfoTec Multi Head Laser System does not require a major overhaul of the line, purchasing gas control modules, or replacing key machines. The solution is designed for rapid retrofitting.

The system integrates directly with existing slitter-rewinders. The installation works perfectly with the current drive controllers of the rewinder, creating an efficient production sequence. From the machine operator's perspective, operation remains simple, and the converting plant avoids multi-day implementation downtimes.
