Paper Bag Bottoms Without Compromise: Strength and Aesthetics
Adhesive Pastes for Paper Bag Bottoms
Makrochem produces in-house developed adhesive pastes for paper bag bottoms that provide strong, reliable bonds capable of withstanding the loads encountered during packaging and transport. Thanks to flexible formulation parameters, we tailor our pastes to your production process, including line speed, paper type, and bonding conditions. This helps increase efficiency and reduce material waste. The result is a durable, aesthetically finished bag bottom and easy integration with existing machinery. We also provide technical support and trial testing to ensure the adhesive is optimally matched to your process.

|
Makrolep ES-65 Adhesive A high-performance adhesive paste based on a blend of unplasticized PVAc dispersion and styrene-acrylic copolymers, designed for bonding labels to metal cans and paper to difficult surfaces. It provides very strong initial grab thanks to adhesion-promoting additives and offers stable operating parameters on automatic gluing machines. Application: packaging production, labeling machines, bonding difficult surfaces to paper and cardboard. |
55,000 - 75,000 mPa·s | 50 - 55% |
|
Makrolep AX-105 Adhesive A modern, high-quality adhesive paste for bonding difficult surfaces. Thanks to its rheological and stabilizing additives, it offers exceptional operating stability even under demanding conditions on high-performance machines. It does not leak or run through adhesive application mechanisms. It provides strong initial grab and excellent adhesion to polyolefin films (PP, PE), aluminum, waxed, and coated papers. Application: bonding paper to difficult surfaces, paper-to-film lamination, bonding film windows into bags and boxes. |
80,000 - 120,000 mPa∙s | 55 - 60% |
Together, let’s create a lasting solution.
Types and Applications
We offer high-viscosity adhesive pastes that stay firmly on the bottom of the bag and do not run during application. They are suitable for the production of paper bags in various formats, from promotional bags to food packaging.
- Sealing the bottoms and bases of paper bags
- Production of paper bags and sacks
- Use alongside longitudinal seam adhesives (see: longitudinal seam adhesives)
Parameters and Selection
The viscosity and open time of the adhesive paste are selected according to the machine speed and paper type. As a manufacturer, we ensure consistent quality from batch to batch, helping maintain a stable bottom-gluing process. We also provide customers with free samples and technical consultation.
