Solvent Free PU Glue Polyurethane Film Lamination Adhesive High Shear Strength

The Polyurethane Adhesive is a high-performance solvent-free lamination adhesive designed to meet the demanding requirements of flexible packaging applications. This innovative adhesive is specially formulated as a two-component system with a precise mixing ratio of A: 100 and B: 65, ensuring optimal bonding strength and durability. The product is provided in liquid form, facilitating easy application and excellent surface coverage, which makes it ideal for use in film bonding, soft packaging, and food packaging industries.

One of the key features of this Polyurethane Bonding Adhesive is its carefully balanced physical properties. Component A has a density of 1.21 g/cm³ at 25℃, while Component B has a slightly lower density of 1.16 g/cm³ at the same temperature. This density balance contributes to the adhesive's superior processing performance and reliable curing behavior. The viscosity of the components further enhances the adhesive's applicability; Component A exhibits a viscosity range of 1200 to 2400 mPa·s, and Component B ranges from 1600 to 2800 mPa·s at 25℃. These viscosity levels ensure that the adhesive flows smoothly yet maintains enough body to achieve uniform coating on film surfaces.

As a professional film lamination adhesive, this product excels in creating strong, flexible bonds between various packaging films. Its polyurethane-based formulation provides excellent leveling property, good heat resistance, and stable lamination performance, making it a preferred choice for high-barrier soft packaging where long-term reliability is critical. The adhesive's ability to bond plastic films securely opens up efficient solutions for modern flexible packaging production.

The Polyurethane Bonding Adhesive is particularly well-suited for film lamination applications, where it delivers exceptional adhesion to a wide range of packaging materials, including PE, CPP, BOPP, PET, PA and high-barrier composite structures. Its versatility extends to the soft packaging sector, where it provides a durable and flexible bond that withstands the rigors of handling, transportation and heat processing. Moreover, the adhesive's formulation complies with safety standards for food packaging, ensuring that it can be used in environments requiring stringent hygiene and safety protocols without compromising bonding quality.

In addition to its outstanding bonding capabilities, this solvent-free polyurethane adhesive is known for its ease of use. The liquid form and well-defined mixing ratio simplify preparation, allowing for consistent mixing and processing. This consistency helps manufacturers achieve uniform lamination quality across production batches, reducing waste and improving overall efficiency. The adhesive works well with standard 2-in-1 and 3-in-1 solvent-free laminating machines, supporting stable high-speed production.

The combination of density, viscosity, and mixing ratio in this Polyurethane Adhesive is engineered to optimize performance in flexible packaging applications. Its robust chemical composition supports excellent adhesion to various films used in soft and food packaging, ensuring stable, reliable lamination effects. End users benefit from a dependable adhesive that balances bonding strength, appearance, and processability, making it an indispensable material in modern packaging production.

In summary, this Polyurethane Bonding Adhesive offers a comprehensive solution for manufacturers seeking a dependable solvent-free lamination adhesive with superior bonding performance. Its liquid form, precise mixing ratio of A: 100 to B: 65, balanced densities, and tailored viscosities make it an ideal choice for film bonding, soft packaging, and food packaging applications. With its advanced formulation, this adhesive ensures durable, stable, and safe bonds that meet the highest standards of quality and reliability.
