Makrolep PD A polyvinyl acetate (PVAc) dispersion-based adhesive, particularly recommended for bonding paper bags (longitudinal seams). Its stable parameters make it highly effective in the production of solid and corrugated cardboard packaging. Application: paper bonding, solid and corrugated cardboard packaging production, paper bag bonding (longitudinal seams). |
8 000 – 12 000 mPa∙s | 50 – 55% |

Makrolep PD/2500 A low-viscosity water-based polyvinyl acetate (PVAc) dispersion designed for use on high-performance automatic gluing machines with nozzle application. Application: paper bonding, solid cardboard packaging production, corrugated cardboard packaging production. |
2 000 – 3 000 mPa∙s | 48 – 53% |
|
Makrolep PD-Super A high-solids, low-viscosity dispersion adhesive. Its increased polymer content prevents the paper from becoming oversaturated, wrinkling, or buckling during production. Once dry, it forms a transparent, flexible, and durable bond with a short setting time. It is used on high-speed folder-gluers for cardboard packaging production and longitudinal seam bonding. Application: paper bonding, solid and corrugated cardboard packaging production, paper bag bonding (longitudinal seams). |
4 000 – 6 000 mPa∙s | 50 – 55% |
Applications
Our adhesives are ideal for the production of paper bags and sacks, as well as cardboard angle boards and paper tubes. They provide fast initial grab and a durable, flexible bond on paper, even at high machine speeds.
