In the production of paper packaging, cartons and paper boxes, choosing the right adhesive determines bond strength, odor, working conditions and line stability. Many businesses are also looking for ways to reduce VOCs during packaging production.

What are VOCs in packaging production?
VOCs are volatile organic compounds that may come from raw materials, solvents or processing operations. In packaging, VOC control should be considered together with material type, adhesive application method, machine speed, temperature and end-product requirements.
Why choose an adhesive with an appropriate VOC level?
- Improved working environment: reduce odor and vapors in the production area.
- Consistent packaging quality: control adhesion, drying time and edge lifting.
- Meet customer requirements: provide clear information about raw materials, chemical safety and quality control.
- Optimize the production line: suitable viscosity and open time reduce application defects and overly fast drying.
Water-based and hot-melt adhesives for packaging
Water-based adhesives are often considered for paper, carton and absorbent surfaces. Check drying time, material moisture, adhesive quantity and machine runnability.
Hot-melt adhesives suit high-speed packaging lines and rapid bonding. Control melting temperature, application temperature, viscosity and stringing risk.
No single adhesive suits every type of packaging. The final decision should be based on trials with the actual paper, carton, coating and production conditions.
How to reduce VOCs in the packaging bonding process
- Check the SDS and TDS before production use.
- Identify the material, coating, moisture level and surface energy.
- Adjust adhesive quantity to avoid excess adhesive, odor and longer drying time.
- Control temperature, ventilation and storage according to safety instructions.
- Record bond strength, drying time, appearance, odor and defect rate during trials.
Packaging adhesive selection checklist
Provide the paper or carton type, coating, line speed, application method, operating temperature, open time, moisture-resistance requirements and odor or VOC requirements. This helps the supplier recommend a suitable adhesive system and operating conditions.
Conclusion
Reducing VOCs in packaging production requires coordinated action at the adhesive, equipment and operating-process levels. TECHBOND can support businesses in evaluating materials and production conditions and selecting a suitable packaging adhesive solution.
