Between surfaces
Bio-mineral adhesives for paper and board packaging
Papkot adhesives go between paper surfaces: seals for packing lines and a white glue for folding cartons. A glue for the corrugator is under development.
Two sealing solutions work on vertical and on horizontal packing lines: RBLB, the release-free cold seal, and P12, the heat seal.

Two sealing solutions
For vertical and horizontal packing lines
RBLB, the release-free cold seal, and P12, the heat seal, work on both lines. Uses include flowpacks and pouches.
Vertical packing line
- RBLB cold seal
- P12 heat seal
Horizontal packing line
- RBLB cold seal
- P12 heat seal
RBLB and P12 work on vertical and on horizontal packing lines.
Between surfaces
What the adhesives do
Coatings go on the surface. Adhesives go between surfaces.
The adhesives are repulpable. All of them except P12 are bio-mineral, based on active silica, and plastic-free, tested by SGS. P12 is the only biopolymer among Papkot grades: it comes from pine trees.
Adhesives are a separate platform from coatings.
- Bio-mineral
- Plastic-free, tested by SGS
- Repulpable
- A coating goes on the surface.
- An adhesive goes between two surfaces.
- The surfaces close: a plastic-free, repulpable seal.
Types and products
Three products: a release-free cold seal, a heat seal and a white glue.
RBLB
Release-free cold sealBased on active silica. It sticks on paper and on PLA at very high speed. The other side of the web needs no release coating.
Vertical and horizontal packing lines · Flexo, gravure, rod, air knife or gap-fed roll
P12
Heat sealThe only biopolymer among Papkot grades: it comes from pine trees. It seals well at a lower temperature. With a full-width coat, the recyclability of the paper stays very high to the CEPI, Western Michigan and GB standards.
Seals at 120 °C · Vertical and horizontal packing lines · Flexo, gravure, rod, air knife or gap-fed roll
RBG
White glueThe white glue for folding cartons. Bio-mineral, based on active silica, and polymer-free. Plastic-free, tested by SGS. Fully recyclable to the recyclability standards from the US to the EU to China.
Folding cartons, at the glue line
More glues
For folding cartons, and a seal that closes on itself
Both glues are based on active silica and plastic-free, tested by SGS.
Folding cartons
RBG, the white glue
Bio-mineral, based on active silica, and polymer-free. Plastic-free, tested by SGS. Fully recyclable to the recyclability standards from the US to the EU to China.
Seals only on itself
Heat-activated cold seal
Plastic-free, tested by SGS, and based on active silica. Heat activates the seal. It seals only on itself: coated face to coated face.

Where the white glue goes
RBG, the white glue, goes on at the glue line of folding cartons, at the converter. It is polymer-free.

How the seals go on the paper
RBLB and P12 go on the paper web like a coating, on the lines you already run: flexo, gravure, rod, air knife or a gap-fed roll.
Then the web dries at 100 to 120 °C, and cools down before it rewinds.
The reel then goes to the vertical or the horizontal packing line.
- Flexo
- Gravure
- Rod
- Air knife
- Gap-fed roll
- The coater puts RBLB or P12 on the web.
- The web dries at 100 to 120 °C.
- The web cools down, then rewinds.
Under development · Corrugated board
A glue for the corrugator
Papkot develops an active silica glue that replaces starch at the corrugator.
The drying time is zero. The glue reacts on contact with the paper.
Starch glue wets the paper with a lot of water and little starch, and the board must dry after. With this glue, the paper does not take that water and the board needs no drying: less energy, more speed.
The glue line is the usual point of failure of wet containerboard. This glue is water resistant, so the glue line is no longer where a wet box fails.
Papkot looks for partners to take this glue to market.
- Under development
- Drying time zero
- Water resistant
- The glue goes on the tips of the flutes.
- The liner closes. The glue reacts on contact: drying time zero.
- Water falls on the board. The glue is water resistant.
Who they are for
For converters and packagers. Papkot supplies the chemistry and the application know-how. Papkot makes the materials, not the pack.
Three platforms
One of three Papkot platforms
Papkot makes bio-mineral papermaking additives and barrier coatings. It develops bio-mineral adhesives for paper and board.
