Water-based adhesive for sealing windows on envelopes and bags

Preflex 46 I is a water-based adhesive formulated for gluing windows onto envelopes and bags. Its formulation allows for application using a disc or linear nozzle, easily adapting to different machine configurations and production methods.

Technical Specifications:

• High initial tack: Provides immediate adhesion between the envelope or bag substrate and the window.
• Good penetration in difficult substrates: Achieves effective penetration in complex substrates that are difficult to adhere to, such as glossy papers or special coatings.
• High performance: Optimizes adhesive consumption in each application, thanks to its ability to cover a larger surface area with less product.
