Release Liner, Label and Tape Inspection
EasyInspect for release liner, label, and tape inspection detects defects and irregularities during each stage of of the production of release liner, label stock and tape materials, especially in the adhesive and silicone layers.
Typical material inspection tasks for primary product labels, point-of-sale labels, functional or security labels include:
- Base label material (gels, burnt spots, orange peel, scratches, streaks, foldings, inclusions…)
- Silicone coating on release liners (missing coating, silicone voids, particles…)
- Release liner base (inclusions, variations in structure…)
- Adhesive film (uncoated areas, coating streaks, drying marks, bubbles…)
- Finished label stock (lamination defects, paper folds, bubbles…)
- Release liner, label and tape inspection
Label material inspection process
For some applications strict legal requirements exist for the information printed on labels to be legible without fail. The printing quality depends largely on the quality of the involved base material. Optical inspection systems are used to ensure label stock quality.
Separating a release liner from a label can also present a challenge when the silicone layers of the release liner were not evenly applied. Putting automated in-line control system in place to inspect and measure the silicone coating process can help to detect irregularities and maintain continuous label stock quality.
Examples of typical coating applications and EasyInspect/EasyMeasure tasks:
- Release liner inspection
- Label material for pharmaceutical applications inspection
- Label material for food products inspection

Label narrow web Rotary Press
The label printing is one of the fields where the dust removal contact system of the AR Series finds its more natural use. In fact, its compactness, the innovative system for the passage of paper at starting no longer provides for the opening of the unit with the hinge as the competitors, but instead the unit remains closed and are the internal rollers to rise through a pneumatic system. This means safety for the operator and less space required for installation, especially in the part above the unit.
Even in the field of labels, however, there is a growing demand for our Contact less solution, the DM1000. This provides extremely high performance, removing dust from both sides of the band without ever touching it. When the amount of dust to be removed is remarkable, DM1000 is the ideal solution for the label printer.

Label Corona Treatment
Installable on printing machines, it gives you the possibility to treat both non-conductive and conductive materials (such as aluminium foils and metalized films). Speeds of production of 250 m/min have already been reached with this equipment obtaining great benefits for adhesion of inks.
Features
- Able to treat one or two sides of the web
- Web width up to 500 mm
- Specific power (energy density) kept strictly constant during running
- Corona roller in aluminium covered with conductive ceramic to guarantee a longer life and a great resistance to the ozone attacks
- Rollers statically and dynamically balanced
- Speed sensor mounted on the corona roller
- Discharge bars in special ceramic material, protected by a sturdy aluminium housing
- Easy removal of discharge group through fasteners for cleaning
- Easy air-gap regulation
- High Voltage inlet studied to have a safe connection absolutely protected by the dust
- Ozone exhaust system coming out on the transmission side in order to avoid any bending of the flexible hose and a better aesthetic effect
- Safety switches shut down the power supply in case of accidental opening of the discharge groups
- Electromagnetic (EMC) compatibility in accordance with EN-55011 and EN 50082-2 standards
- Optional: Overpressure version for explosive proof environments
Compact power – Great innovation down to the smallest detail
The market for paper and label production is dynamic: sustainability drives innovation, small print runs demand flexibility, and cost pressures require maximum efficiency. In this challenging environment, Kampf is your strong partner who combines proven technologies with state-of-the-art solutions and innovative possibilities – throughout the entire life cycle of your machines.

Matrix Waste Removal for Label Printing and Converting
In your production you very likely have both label presses and converting machines creating edge and matrix waste that needs to be removed thoroughly to have a smooth and efficient operation. Around the world you will find hundreds of converting machines and label presses equipped with Lundberg Tech waste removal systems. Our systems are designed specifically to ensure a smooth handling of self-adhesive label waste.
The Lundberg Tech waste handling systems for trims and matrix are based on cutting the matrix and edge trim into small pieces, using our efficient Granulators, and afterwards transporting the adhesive waste through non-stick treated components to a designated collection point.
Benefits & features
- Eliminates the need to manually handle heavy matrix rolls
- Increases the throughput due to fewer stops
- Collects waste centrally indoor or outdoor and frees up floor space
For more than 40 years Lundberg Tech has designed and manufactured waste handling units and systems for label printers and converters. We are especially well-known for our ability to handle even the stickiest label stock waste using our unique oil dispensing system.
The Granulator is the core part of all our waste handling solutions and they come in a wide variety of sizes, so we are able to capture matrix waste from all width conventional label presses as well as full-web from digital presses.
Lundberg Tech waste handling systems can handle all the different types of materials you find in a modern label facility including linerless labels.
A variety of solutions for waste handling
For label printing and converting, you can purchase our All-in-one Units for collecting trims and matrix from one or several machines. The Lundberg Tech All-in-one Units offer all you need for removing and collecting label waste. Another advantage is that they are easy to install.
We can also design a Central System tailored to your individual needs. Our Central Systems can collect adhesive and non-adhesive waste from an unlimited number of machines. Furthermore, the systems can be designed with material separation to take recycling into account.
If you already own a system and are looking to expand with an extra Granulator, then contact us. We can assist you choosing the right one from our wide range of own designed and manufactured Granulators.
