Incorrect adhesive weight is a common cause of critical production defects such as orange peel, blisters, and telescopic winding. These issues are especially prevalent when processing high-barrier or metallized substrates at high speeds, and in the presence of specific inks.

With GCM’s system, the operator simply sets the desired adhesive grammage—either manually or using presets—and the machine automatically adjusts and maintains the target value throughout the job. The system also manages real-time mixing ratios, tracks component consumption, and activates alarm signals up to complete line stoppage in case of persistent errors.

A Market-Leading System, Without External IR Sensors

Unlike traditional systems that rely on expensive IR technology with wide tolerance ranges, GCM’s proprietary solution delivers precise, stable and cost-effective performance, offering multiple advantages:

• Elimination of optical issues such as orange peel, surface blisters, and skin effects
• No more telescopic winding due to uneven adhesive application
• Consistent grammage throughout the process, preventing variability over time
• Real-time ratio control, with alarms and machine shutdown for persistent misbalances
• Reliable adhesion strength across all runs
• Minimized production waste from inaccurate adhesive settings

In practical terms, for a transparent film structure where only 1.4 g/m² is needed, over-applying even slightly (e.g. 1.7 g/m²) increases costs without benefit. GCM’s system corrects this in seconds via the operator panel, maintaining ideal weights and preventing excess use.
