Flex Packaging Lamination | PUR Adhesive Solutions

Two-Component PUR Adhesive Solutions for Flexible Packaging

Two-component PUR adhesive is a revolutionary innovation pioneered by Sinohesive Company, specifically designed for multi-layer lamination of high-end flexible packaging materials. It completely replaces solvent-based adhesives and is ideal for high-barrier structures such as PET/AL, PET/VM-PET, etc., offering excellent appearance, high bonding strength, resistance to boiling water, ease of operation, and high production yield. It is the preferred choice for premium food packaging, pharmaceutical packaging, electronic product packaging, and industrial packaging.

Core Advantages

Compatibility with Aluminum Foil Structures

Highly suitable for rigid/rigid structures such as PET/pure aluminum, OPP/pure aluminum, and PET/VM-PET. Delivers excellent lamination appearance and reliably resolves issues like white spots, gray spots, and glue penetration through aluminum foil pinholes.

High Initial Tack

Provides high initial tack similar to dry bond laminating adhesives, enabling rapid positioning between film layers.

No Primary Aromatic Amine Migration

Fully complies with stringent hygiene and safety requirements for food and pharmaceutical packaging.

Zero VOC Emissions & Cost Efficiency

No need for organic solvents during application, ensuring no volatile emissions. The production environment remains safe and odor-free, with significantly reduced adhesive costs compared to solvent-based dry laminating adhesives.
