Tie Layers & Extrudable Adhesive Resins

Tie layer resins are functional polyolefins that are produced by grafting anhydrides or acids onto a polyolefin substrate through a post-reactor process. These resins play a crucial role in multi-layer structures by enabling adhesion between dissimilar resins that normally would not bond well together.

Maleic anhydride modified polyolefin based compounds

The Yparex extrudable adhesive resins of The Compound Company are ideal for all kinds of multilayer applications. The resins provide outstanding adhesion between materials with different polarity, e.g. EVOH, PA, poleysters with polyolefins. Yparex tie layer resins are used across a broad temperature range – and for a wide portfolio of applications and industries, from multi layer packaging to building and construction, like underfloor heating, super bond (unibond) aluminium composite panels, multi layer composite pipes, drinking water pipes and high-voltage cables. Yparex is based on maleic anhydride-(MAH)-modified and functionalized polyolefin compounds. This all makes it an ideal coupling agent and compatibilizer, as well as an excellent tie-layer resin.

Yparex tie layer adhesive resins for multi-layer film packaging

When incompatible materials are used in film packaging tie-layers are needed to achieve the right properties. This is precisely what our Yparex tie-layer resins provide for manufacturers of multi-layer packaging, whether for food-contact bottles, multi-layer pouches (e.g. for fish, cheese, meat), or industrial applications like agricultural films.

Sustainable Yparex RENEW biobased tie-layer resin

Yparex RENEW is the first biobased tie-layer resin for multilayer packaging, derived from non-food based European feedstock and fully recyclable. It achieves outstanding adhesion between all forms of polyolefin-based resins and different materials including metals (aluminium, steel, and copper), and barrier plastics (polyamides, nylons) with ethylene vinyl alcohol (EVOH). Our Yparex RENEW products are good for the planet, but also have excellent optical and mechanical properties.

Tie layer resins for adhesive films

Applied as solids in flexbile, thin layers, our Yparex extrudable adhesive resins are ideal for bonding polyolefin (PE or PP) substrates with various polar substrates – including polyamide, aluminum, glass fibres and natural fibres. Unlike liquid adhesives, Yparex adhesive film is very low on volatiles.
