Liquid 2 Part Polyurethane Adhesive PU Adhesive For Plastic Bonding

The Solvent-Free Polyurethane Lamination Adhesive is an advanced two-component PU adhesive designed to deliver superior bonding strength and durability for flexible packaging applications. This high-performance adhesive is formulated without solvents, making it an environmentally friendly choice that ensures safety and reduces VOC emissions during use. Its excellent properties make it ideal for film lamination and soft packaging requiring strong and long-lasting bonds.
This adhesive system consists of two components: Component A (Isocyanate) and Component B (Polyol). Component A is available in 25 Kg/drum and 220 Kg/drum; Component B is available in 20 Kg/drum and 210 Kg/drum to meet different production demands. At 25℃, Component A has a density of 1.21 g/cm³ and Component B has a density of 1.16 g/cm³, ensuring stable mixing and consistent performance.
At 25℃, the viscosity of Component A ranges from 1200 to 2400 mPa·s, while Component B ranges from 1600 to 2800 mPa·s. This well-balanced viscosity allows smooth coating, good leveling, and uniform application on various film surfaces without sagging or running.
This solvent-free PU adhesive provides reliable bonding for PE, CPP, BOPP, PET, PA and high-barrier composite films. It features good heat resistance and works well with standard 2-in-1 and 3-in-1 solvent-free laminating machines, making it widely used in soft packaging, food packaging, and spout pouch production.
The solvent-free formula enhances safety, supports environmental compliance, and fits sustainable production requirements.
In summary, this Solvent-Free Polyurethane Lamination Adhesive is a professional, reliable, and eco-friendly solution for flexible packaging. With stable performance, easy processing, and well-controlled physical parameters, it ensures high-quality lamination and durable bonds for various packaging applications.
