- Secure food-packaging seals with DEGALAN® heat-sealable coatings
- Expansion of product portfolio for water-based heat-seal binders
Heat-seal binders from Evonik Industries are a major component of heat seal coatings for aluminum foils and plastic films. These binders provide a secure seal for food and pharmaceutical blister packaging. Lids for yogurt cups can be opened smoothly with a clean peel and with no residual materials: the heat-seal coating does not delaminate or produce stringing. As a result, PVC-free binders with DEGALAN® have become established as the standard for dairy product packaging in Europe (EMEA). DEGALAN® PM 666, for example, leads the market in solvent-based, primerless heat seal formulations. DEGALAN® is also used as a universal binder for manufacturing heat-seal lacquers applied directly to aluminum foils in order to seal with polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), or vinyl (PVC).
In 2014 DEGALAN VP P34, the next generation of heat-sealable bead polymers, will be launched. DEGALAN VP P34 can be applied directly to aluminum foil. A formulation with a PVC copolymer based adhesion promoter is no more necessary.
With the market launch of DEGALAN® VP 4240 D last year, Evonik expanded also its portfolio of water-based heat-seal binders. The product is an aqueous dispersion of a methacrylate-based heat-seal binder with a solids content of 50 percent. DEGALAN® VP 4240 D is a binder developed for manufacturing PVC-free, aqueous heat-seal lacquers that adhere directly to aluminum, making this binder particularly suitable for sealing aluminum foil to polystyrene cups.
DEGALAN® VP 4240 D achieves optimum sealing properties at a coating thickness of 7 µm (dry). A heat seal strength between 6 and 8 N/15 mm is achieved. Like all DEGALAN® heat-seal binders, DEGALAN® VP 4240 D meets the requirements specified in FDA 21 CFR sec. 175.300. Samples of DEGALAN® VP 4240 D are available.
