The Advantages of Our Flex Packaging PUR Adhesive RG1128
1. Solvent-Free & Eco-Friendly
SINOHESIVE® RG1128 is a two-component PUR adhesive solution designed for high-end flexible packaging lamination. It completely replaces solvent-based adhesives, helping create a safer, odor-free production environment with zero VOC emissions.
2. Excellent Compatibility with High-Barrier Structures
It is highly suitable for multi-layer lamination of high-barrier flexible packaging materials, especially structures such as PET/AL, Nylon/AL, OPP/AL, PET/VM-PET, BOPP/VM-PET, Paper/Aluminum Foil, and PET/Paper.
3. Outstanding Appearance & Aluminum Foil Adaptability
RG1128 performs especially well on aluminum foil structures and rigid-to-rigid laminations. It delivers excellent lamination appearance and helps solve common problems such as white spots, gray spots, and glue penetration through aluminum foil pinholes.
4. High Initial Tack & Efficient Lamination
The adhesive provides high initial tack similar to dry bond laminating adhesives, enabling rapid positioning between film layers and helping improve production yield and line efficiency.
5. Safe for Food & Pharmaceutical Packaging
The formulation contains no primary aromatic amine migration, meeting strict hygiene and safety requirements for food packaging, pharmaceutical packaging, and other high-value packaging applications.

Key Process Description
1. Adhesive Preparation
SINOHESIVE® RG1128 is used as a two-component PUR adhesive system for flexible packaging lamination. It is prepared according to the required process conditions before coating.
2. Uniform Coating Application
The adhesive is applied evenly onto the target film or foil surface to form a thin and consistent bonding layer, helping ensure stable wetting and clean lamination appearance.
3. Film-to-Film Lamination
After coating, the target substrates are laminated together under controlled pressure and line conditions. The high initial tack helps achieve fast positioning and smooth layer integration.
4. Bond Development
After lamination, the adhesive system continues to build durable bonding strength, supporting high barrier performance, stable structure, and reliable finished-package quality.
Benefits in Flexible Packaging Applications
High-Barrier Food Packaging
Ideal for premium food packaging structures that require strong bonding performance, clean appearance, and resistance to demanding filling or boiling conditions.
Pharmaceutical Packaging
Suitable for pharmaceutical packaging applications that require high hygiene standards, no primary aromatic amine migration, and stable multi-layer lamination performance.
Electronic & Industrial Packaging
Also suitable for electronic product packaging, specialty product packaging, and industrial packaging where high barrier performance and efficient lamination are required.
