Functional Barrier Solutions
Using Functional Barrier Solutions to Achieve Sustainability in Flexible Packaging
Sun Chemical has developed a mix of products which provide various levels of performance to enable a smooth transition into mono-material packaging without any compromise. We can uniquely offer a full comprehensive set of products designed for flexible packaging. These products can be combined to provide a unique and differentiated approach to the market.
- Full range of oxygen barrier enhancement coatings specifically designed for polyolefin and as protection (topcoat) from aluminum oxide (AlOx) and silicon oxide (SiOx)
- This product has been enhanced with recent developments for use with in-line printing processes to assure barrier performance, reducing the production processes involved.
- This range of barrier adhesive was designed with new grades that include a solvent-based version for retortable applications and a solvent-free version for application up to pasteurization.
- The solvent-free barrier adhesive has been developed specifically to allow easy processability of some polyolefin-based substrates without compromising the mechanical and dimension stability and avoiding the drying process of solvent into the oven and to open new opportunities to any converter not equipped with solvent based laminator.
Overprint Varnish (OPV)
- Full range of thermal resistance overprint varnish which improves the thermal stability of some polyolefin-based materials during the packing line processability.
- This OPV reduces the risk of jaw stickiness and improves production speed and provides similar performance of other plastic material commonly used as outer layer in multi-material solution.
In partnership with BOBST, oneBARRIER offers a mono-material plastic-based flexible packaging alternative and is recyclable. The solution utilizes the synergies between wet barrier coating, dry vacuum deposition and 2-in-1 barrier adhesive to achieve a high-barrier packaging solution.
