Plasma Surface Treatment Equipment
Surface preparation equipment to improve adhesion on compatible coated and laminated materials before gluing or printing.
Protek’s Plasma Surface Treatment Equipment
Protek’s KQ plasma surface treatment range includes direct-injection and rotary-nozzle systems. These machines prepare selected areas of a material before the next production stage, helping address adhesion difficulties on substrates such as laminated board, UV-varnished cartons and metallised packaging.
Preparing Difficult Surfaces for Bonding
Coatings and laminates can make it difficult for adhesive to wet and bond to a packaging surface. Plasma treatment modifies the exposed surface to improve its receptiveness to the selected adhesive.
Treatment is applied before gluing and must be matched to the substrate and production process. Testing the material, treatment settings and adhesive together helps establish whether the required bond can be achieved.
Direct-Injection and Rotary-Nozzle Options
Direct-injection systems treat a narrow area, making them suitable for targeted work along a carton’s bonding edge. Rotary-nozzle systems cover a wider area for applications requiring broader surface treatment.
The supplied KQ range includes different nozzle and head configurations. Suitable systems can be integrated with folder gluers, box-making equipment and compatible printing lines.
Selection depends on the treatment width, material, line speed and available installation space. Protek can help assess which arrangement suits your application.
Discuss Your Surface Adhesion Challenge
Match the treatment system to your material and bonding process.
Tell Protek about your substrate, coating, adhesive and current bonding issue. Material samples and production details will help establish the appropriate treatment approach.
Frequently Asked Questions
Why use plasma treatment before gluing?
Plasma treatment can improve the surface’s receptiveness to adhesive, particularly where a coating or laminate makes bonding difficult. The result depends on the material, treatment settings and adhesive combination.
What is the difference between direct-injection and rotary-nozzle treatment?
Direct-injection nozzles treat a narrower area, such as a bonding edge. Rotary nozzles treat a wider area. The choice depends on the size and shape of the surface requiring treatment.
Can plasma treatment be integrated into an existing production line?
Integration may be possible on compatible folder gluers, box-making machines and printing equipment. Installation requires an assessment of available space, material movement, services and machine controls.
