Plastic & lamination Industry
Roll coverings for the plastic film and lamination Industry
With the evolution that has taken place in the plastic sector, specifically flexible packaging, reaching speeds and manufacturing environments in very demanding plastic film machines, it is essential to have rollers cover and elastomer presses with the right properties for this industry. This is where Raj Rubber comes into play, thanks to our experienced research team in the manufacture of roller cover with constant innovation in the world of roller coating formulations for the plastics film sector, lamination sector and the flexible packaging industry, we have an extensive repertoire of exclusive formulas for roller coatings to your plastic film machinery.
Synthetic and natural rubber coatings for rollers, press roller and laminators in their great variety, have been present in the elaboration and transformation of plastic films in their different aspects (formation, printing, stamping, lamination, etc.).
Now a days, with the constant innovations of the plastic film industry and packaging in general, it is essential to have the rollers covered with the most technologically advanced materials and the strictest quality controls in order to achieve the highest working speeds and maximise the final quality of the packaging product.
Closing and Pressure Rollers
In the process of forming plastic film sheet it is essential to have rollers cover with quality coatings, either for globe extruders or in-line or calendar extrusion machines.
The pressure roller is responsible for pressing the plastic sheet, and can control its stretching and thickness, thereby achieving the desired tension of the plastic film in our extruder.
The rollers have the latest in cylinder coatings resistant to high temperatures and abrasion, allowing us to obtain the desired flexible film sheet from the bubble of the blown film.
- Covering of closing rollers with excellent resistance to high temperature.
- Roller coatings with good resistance to ozone degradation.
- Pressure roller covering with very good physical properties.
- We manufacture rollers cover for any plastic extrusion machine.
- Pressure roller covering with high resistance to abrasion.
Spreader Rollers
Raj Rubber curved spreading rollers and their coatings are specially formulated to avoid one of the main challenges in the production of film for flexible packaging and other industries, this is the appearance of wrinkles in the plastic film.Our spreading roller for flexible packaging and banana curved rollers are made to measure for each machine, these curved opening rollers can eliminate the appearance of wrinkles, incredibly reducing the amount of waste in the manufacture of the film, in addition these spreading rollers allow us to get thinner plastic films and accelerate the production process in our extruder machines.
We manufacture, repair and cover curved banana rollers.
- Spreader rollers of high quality and durability.
- Designed to reduce waste in the manufacture of flexible packaging.
- Coatings that minimize pressure differences in the film.
- Banana spreader rollers that increase machine speeds.
- We manufacture high quality curved opening cylinders.
Winding Rollers
In the winding and unwinding section, various rollers with finished coatings in a multitude of geometries are involved in order to remove air from the plastic film and ensure that the production of the flexible film is free of wrinkles and flaws.
Raj Rubber has the machinery, technical knowledge and experience to carry out any geometry, pattern or drawing required by the customer for each coating of winding rolls, rolls grated in diamonds, oblique groove of different depth with elastomer coatings of various hardnesses, etc…
We also have coatings for all types of flexographic roller for plastic film winding and unwinding machines with conductive and antistatic properties in a wide range. This allows us to improve even more the control of the tensioning of the flexible film, ensuring a magnificent finish during winding.
Spreader rollers of high quality and durability.
- Antistatic and conductive winding roller covers.
- We have all types of rollers and sleeves for winders.
- Cylinders for film winding machine with infinite geometries.
- The best rollers to eliminate the air in your unwinder.
- Roller with perfect coupling between the plastic film and the roller.
- Technical coverings with different anti-wrinkle surface finishes.
Laminating Rollers
We produce rollers for lamination of plastic films and foils and other materials with the best compounds of synthetic and natural rubbers, thanks to our refined technique of confection of rollers, each one of our coatings for laminating roller has an unbeatable capacity of recovery before the deformation, besides an excellent elasticity and great resistance to the abrasion and dynamic load.
Raj Rubber lamination rollers are available in reinforced steel cores and customized cylindrical or conical finishes. As each flexible packaging product is different, our technical elastomer coatings for each lamination roller will have the required properties, be they greater resistance to humidity, solvents, inks, adhesives, antistatic, conductive or semiconductor properties.
- Roller resistant to products used in lamination such as inks, solvents or additives.
- Coatings for high speed pressurized roller.
- Applicator roller that optimize adhesive transfer.
- Technical elastomer coverings with conductive, semiconductor or antistatic properties.
- Roller with surface finishes with very good resilience and dimensional stability.
- Custom rollers for film laminating machinery.
Other products for Flexible Packaging
