Casein glue is formulated from casein, crosslinker, modified starch, urea, viscosity modifier, defoamer, preservative (potassium sorbate), and other raw materials through heating, dissolving, and polymerization in water. Primarily used for bonding paper trademarks to glass and paper materials, this adhesive is suitable for machine labeling (straight type, rotary type) with operational speeds ranging from 2,000 to 60,000 bottles per hour.
Available in summer and winter formulations to accommodate different seasonal temperatures and operating conditions.
Severe glue splattering on the labeling machine, with massive buildup on the roller, frames, and the floor.
The equipment is clean and tidy, with no glue splashing, overflow, or residue.
Root Causes: Insufficient glue cohesion leading to easy dripping, and inadequate adhesion to the application roller, causing frequent glue splashing.
Optimized cohesion for stronger self-strength of the adhesive layer with precisely controlled adhesion to the application roller. This prevents glue buildup and splashing, ensuring long-term clean operation.
