Why You Need Hot Melt Label Glue Reactor? | JCT Machinery

June 23, 2025
  • Hot melt label glue reactor has the characteristics of high temperature strong stirring, vacuum degassing, and strong viscous material processing ability. It is the main equipment to ensure the quality of high-quality self-adhesive hot melt label glue products.

Hot Melt Label Glue Reactor Function
1. Raw material melting and mixing
EVA resin, tackifier, wax and other solid raw materials are melted into a uniform colloid at high temperature (180-250℃).
2. Physical property control
Control key parameters such as viscosity and melt index through temperature/stirring.
3. Quality assurance
Remove bubbles/impurities to ensure the purity of the colloid (bubble content ≤0.3%).
