Paramelt has developed a new range of water based, heat activated adhesives. These unique materials offer cost effective and environmentally sound solutions and enable completely new design concepts or product constructions to be achieved. The basis of this technology is the ability to produce previously unavailable, high solids, water based dispersions of high molecular weight thermoplastic polymers. Enabled by the unique flexibility of BLUEWAVE™ Technology from Dow, this approach allows complete freedom of material selection in optimising performance and functionality of water based heat seal coatings.
Aquaseal® heat sealable dispersions offer numerous economical and environmental benefits:
Paramelt have concentrated initial Aquaseal® developments on polyolefins, offering a range of dispersions based on PE and PP copolymers together with other high ethylene content materials such as EAA and EVA.
This versatility in material selection allows property optimisation based on application requirements rather than material limitations. In this way, products can be designed to achieve the best balance of characteristics, such as:
Aquaseal® heat sealable dispersions offer numerous economical and environmental benefits:
- solvent free alternatives to solvent based lacquers;
- potential for significantly lower coating weight compared to extrusion;
- possibility of partial coating to have functionality only where needed;
- contain little or no VOC’s;
- high solids (up to 60%) offer reduced supply chain costs and environmental impact.
- application using standard printing/coating methods: flexo, gravure, rotary screen, air knife, etc.

This versatility in material selection allows property optimisation based on application requirements rather than material limitations. In this way, products can be designed to achieve the best balance of characteristics, such as:
- matched substrate affinity;
- tailored seal initiation temperature;
- controlled Coefficient of Friction (COF);
- low in-reel blocking;
- broad sealing range for maximal operating window.
