Industry Background
In the production of air filters, especially during pleating and edge bonding processes, hot melt adhesive performance plays a critical role in product quality and production efficiency.
Many manufacturers using conventional hot melt adhesives are forced to double the glue application to achieve stable bonding. This results in high long-term adhesive costs, inconsistent product quality, and an increased rate of defective products.
Customer Challenges
• Excessive adhesive consumption to ensure bonding strength
• High and uncontrollable production costs
• Poor consistency in finished filters
• Elevated defect and rework rates
Solution: Poseidon Hot Melt Adhesive
The customer replaced their original hot melt adhesive with Poseidon Hot Melt Adhesive on the same production line while keeping equipment and process parameters unchanged.
Results showed clear improvements:
• Uniform glue lines with low-density formulation
• Strong and stable bonding without increasing glue dosage
• Clean pleats and well-structured filter media
• Improved overall production stability
