BOPP (biaxially oriented polypropylene) film lamination adhesives are specialized adhesives used for bonding BOPP films with other materials (such as paper, plastics, etc.). Based on their chemical composition and application characteristics, they can be mainly categorized into the following types:
- Solvent-Based Lamination Adhesives
These adhesives use organic solvents (such as ethyl acetate) as a medium and feature strong initial tack and fast drying, making them suitable for high-speed lamination processes. However, they have poor environmental friendliness and are gradually being replaced by water-based adhesives. - Water-Based Lamination Adhesives
Using water as a dispersion medium, these adhesives are non-toxic and environmentally friendly, complying with modern green production standards. Although they dry more slowly, they offer stable bonding performance and are widely used in food packaging and other fields. - Solvent-Free Lamination Adhesives
These adhesives cure through chemical reactions, contain no volatile solvents, and are energy-efficient and eco-friendly with high production efficiency. However, they require advanced equipment and precise process control, making them suitable for high-end packaging materials. - UV-Curable Lamination Adhesives
Utilizing ultraviolet (UV) curing technology, these adhesives offer rapid curing and low energy consumption, making them ideal for specialized applications such as electronic packaging and other precision industries.
When selecting a lamination adhesive, factors such as bonding strength, environmental impact, cost, and process conditions should be considered to meet the diverse requirements of different industries.
