In the complex world of polymer co-extrusion, bonding disparate materials like Polyethylene (PE) to functional barrier layers (e.g., EVOH, Nylon, metal) is a critical engineering challenge. Aria Polymer’s Tie Layer Adhesives are specialized, high-performance bonding agents engineered to create robust, lasting adhesion between typically incompatible layers, ensuring the structural integrity and long-term performance of multi-layer products.
A Tie Layer Adhesive is a chemically modified polymer, typically a polyolefin such as PE or PP, that has been functionalized (e.g., with maleic anhydride, creating MAH-grafted polyolefin). This functionalization allows it to react with and strongly bond to polar, non-polyolefinic layers. This intermediate layer is essential for preventing delamination and ensuring the final product maintains its intended barrier, mechanical, and thermal properties under demanding conditions.
Aria Polymer offers a comprehensive portfolio of polymer adhesives specifically formulated for the most challenging industrial applications:
Creating secure, hermetic bonds in multi-layer co-extruded films used for food packaging, medical barriers, and industrial applications, ensuring superior barrier properties and seal strength. Examples of critical film structures bonded by our adhesives include high-barrier food packaging structures, such as PE + Adhesive + EVOH + Adhesive + PE, and high-strength, puncture-resistant barrier films, such as PA + Adhesive + PE + Adhesive + PA (where PA is Polyamide or Nylon).
Used as the crucial adhesive layer in 3-Layer Polyethylene (3LPE) or Steel Pipe Coating (SPC) systems applied to steel pipes for robust, long-term anti-corrosion protection.
Providing enduring adhesion in systems such as PEX/PERT + Adhesive + EVOH for critical oxygen barrier applications in heating and plumbing systems.
Crucial for bonding metal and polymer layers in complex, high-performance structures like PEX/PERT + Adhesive + Aluminum/EVOH + Adhesive + PEX/PERT/EVOH.
Used as the critical tie layer in multi-layer integrated plastic fuel systems, including both fuel tanks and the associated multi-layer pipes. This group of adhesives ensures superior long-term adhesion, toughness, and aging resistance, resulting in systems with low permeation and superior durability.
Designed as an intermediate layer between polyolefin layers and polar layers (Al, Steel, PA, EVOH…) in High Voltage Transmission Lines (HVDC). These adhesives help reduce space charge accumulation and contribute to material efficiency in complex cable structures.
Providing enduring adhesion between structural layers in drainage and utility piping, including those reinforced with steel.
Essential for maintaining the structural integrity and barrier properties of co-extruded Aluminum Barrier Laminate (ABL) and Plastic Barrier Laminate (PBL) tubes. Our PE/LLDPE-based resins ensure a high, permanent bond between the polyolefin layers and the essential barrier materials (e.g., PA, EVOH, PET), preventing delamination throughout the tube’s lifespan.
As a specialist in polymer technical solutions, Aria Polymer develops and manufactures Tie Layer Adhesives with superior bonding strength, excellent processability, and thermal stability.
