When designing packaging (material) in today’s context of the circular economy, not only the mere functionality of the packaging, but also the environmental impact has to be considered. Sourcing and end-of-life scenarios for the packaging material have become decisive criteria.
This has led to renewed interest in paper-based packaging. In combination with suitable coatings they can offer the required barrier and heat-seal functionality needed for many packaging applications.
Paramelt provides 2 key platforms enabling the creation of high-performance packaging papers whilst maintaining the benefits of this highly attractive substrate:
- Paraflex Nowax – renewable vegetable-based coatings.
Paper functionalized with our Paraflex Nowax coatings, yields equivalent barriers to polyethylene whilst remaining inherently biodegradable. Our coatings are applied in the same way as wax-coatings, and can be used in a wide range of packaging applications. They offer a solution for all ‘end of life’ scenarios, be that landfill, littering, recycling or composting.
- Aquaseal – waterbased polyolefin dispersions of conventional extrusion-grade plastics.
Although 10-12 gram of plastic per square meter of paper is often enough to achieve heat seal and barrier performance, it is difficult to consistently apply such thin layers with extrusion techniques. A thinner, water-based coating, which can be applied using conventional coating and printing techniques, will inherently yield a lower overall MVTR but this is frequently sufficient for the target application. The heat-seal functionality remains, but more importantly, the packaging material remains fully repulpable and recyclable via existing waste streams using appropriate processes.
Next to these novel products to functionalise paper-based packaging, Paramelt also offers adhesive products for various applications:
- EXCELTA (PO-based) and PLASTOMELT (EVA- or EBA-based) hot melt adhesives for end-of-line packaging, tray forming and box closing applications.
- PLASTOFLEX pressure sensitive adhesives for the production of e-commerce bags, document envelopes, window bags and various other applications.
- MULTICOLLAC and LATYL water-based adhesives for labelling applications in the beverage and food industry.
- ENZIFLEX and LATYL water-based adhesives for paper and board converting.
