Paper and packaging
Whether it is bleaching and paper coating, films for multilayer packaging or additives for bioplastic packaging… The specialists in the Arkema group provide solutions which are effective and respectful of the environment.
Mastering paper coating techniques
To improve the coating of paper and cardboard, Coatex, a subsidiary of the Arkema group, today applies the latest breakthroughs in the synthesis of hydrosoluble polymers. Its product range is based on its unique know-how in mastering techniques related to the viscosity (rheology) of coating colors applied to the surface of paper. Its range of products includes rheology modifiers (RheocoatTM, RheocarbTM) and polyacrylate dispersants (TopsperseTM).
Focus on... RheocarbTM and TopsperseTM
Coatex has developed two new environmentally sound solutions aptly suited to inkjet paper, which help improve the surface quality of the paper, and reduce manufacturing costs and cycles, hence wastewater emissions.
Rheocarb™ J 40 rheology modifier improves water retention and the dispersion of coating color particles. Topsperse™ JX A dispersing agent protects pigments from flocculation, and controls the stability of coating color viscosity.
For whiter paper
As the world’s third largest producer of hydrogen peroxide (or oxygenated water) and the European leader in sodium chlorate, the Arkema group is today a major supplier of pulp and paper bleaching products under the Alpure® and Albone® brands. It has production facilities in Asia, Europe and North America.
Stable, colorless and biodegradable, hydrogen peroxide does not produce any by-products.
The growth of multilayer packaging
With its worldwide recognized brands such as Orevac®, Lotader®, Lotryl® and Evatane®, the functional polyolefins of the Arkema group have led to the widespread use of multilayer packaging thanks to their excellent adhesive properties. Whether in the form of bottles, packs, sachets or trays, whether flexible or rigid, it is possible to combine the respective advantages of different materials (plastic, cardboard, aluminum) in order to create very effective barriers between the contained items (e.g. a food product) and outside the packaging.
Focus on... Orevac®
Odorless, highly transparent, heat resistant, completely safe and easy-to-use, Orevac® resins are perfectly suited to the production of trays for prepared food. They can be hot-filled and do not affect the taste or quality of the food.
Developing the use of bioplastics
Polylactic Acid (PLA) is a bioplastic made from lactic acid and is used in the food industry to package sensitive food products. However, PLA is too fragile and is not compatible with many packaging manufacturing processes. The Arkema group therefore developed Biostrength® additives, a family of impact modifiers specially designed to enhance the mechanical properties of PLA. Thanks to these additives, PLA can now be used in a great number of applications: transparent or opaque thermoformed packaging, bottle blow molding, injection molding for complex parts, etc.
Surface treatment additives to extend the lifespan of glass bottles
The Arkema group is the world leader in glass bottle coating technology, not only for bottle makers, but also for beer bottlers, non-alcoholic beverages and mineral waters, and users of returnable bottles.
The implementation of the Kercoat® protection technology in bottling chains, coupled with Opticoat® masking coating, protects returnable bottles against scratches and marks, masking them when they do appear, and thereby considerably extending the lifespan of returnable bottles.
