poly tie layer

Poly tie layer is a specialised adhesive polymer used to bond materials that are otherwise incompatible. It plays a critical role in combining different polymers into a single, high-performance structure.

By enabling strong adhesion between polar and non-polar materials, tie layers prevent delamination and enhance the overall durability, strength, and functionality of the final product. They are widely used in packaging, industrial films, and advanced barrier applications.

The tie layer film bonds two dissimilar materials together when it is put under heat and pressure. It is perfect for applications wherein liquid glue/adhesives are not desirable. 

Key Features:

• Strong bonding between dissimilar materials, such as foam, leather and metal in automobile applications.
• Prevents layer separation and failure
• Improves structural integrity of multi-layer films
• Supports high-performance and barrier applications
   

Examples:

• Automotive roof liners: Bonding foam, fabric, and backing films for structural stability
• Door panel moisture barriers: Multi-layer films with enhanced durability and adhesion
• Seat insulation layers: Laminated structures combining foam and films
• Blister packaging: Ensuring strong adhesion between plastic and foil layers
• Cable insulation and sheathing: Bonding different polymer layers for durability
