Meler Multi-Stroke Hot Melt Applicator for Sift-Proof Case Sealing – Configurable

High-Speed Hot Melt Applicator for Sift-Proof Case Sealing and Hermetic Packaging

The Meler Multi-Stroke Hot Melt Applicator is designed for sift-proof case sealing applications where complete adhesive coverage and hermetic sealing are critical. Engineered for packaging lines handling powders, granulates, and other leak-prone products, it delivers precise, repeatable adhesive patterns to ensure secure top and bottom flap sealing.

Built on a robust applicator platform with high-speed performance up to 8,500 dots per minute, it supports dynamic, multi-stroke operation for improved adhesive distribution and sealing integrity. Its modular nozzle configurations and compatibility with standard Meler systems allow flexible integration into vertical form fill seal (VFFS) lines and high-speed case packaging environments, while maintaining consistent performance and serviceability.

Benefits of Meler Sift-Proof Applicators

• Siftproof Sealing Performance: Designed for hermetic case sealing to prevent leaks in powder, granulate, and dust-prone packaging environments.
  
• Multi-Stroke Adhesive Application: Delivers multiple adhesive shots per cycle for improved coverage, stronger flap bonding, and reduced risk of seal failure.
  
• High-Speed Operation: Capable of up to 8,500 dots per minute to support high-throughput packaging lines without sacrificing accuracy.
  
• Configurable Nozzle Geometry: Interchangeable vertical, angled (20°), and horizontal nozzles allow precise pattern control based on application requirements.
  
• Robust Industrial Design: Built on proven applicator platforms for durability, consistent performance, and long service life in demanding production environments.
  
• Built-In Adhesive Filtration: Standard 100 mesh filtering (with optional 50 and 200 mesh) helps prevent nozzle clogging and maintain consistent flow.
  
• Flexible Pneumatic Actuation Options: Available in single or double-acting configurations (AOSC/AOAC) to match system control preferences and response requirements.
