Product name
SIGNO Seal & Cut Machine

Overview
SIGNO is a sealing and cutting machine engineered to process hollow-profile polypropylene sheets (alveolar, BubbleGuard laminated, honey-comb) supplied in sheet or roll form. The system achieves sealing performance compliant with ISO 62 (water absorption) and is designed for manufacturing interlayer pads, hollow-profile boxes and packaging for food and pharmaceutical applications.

Key features

• Lightweight sealing and cutting press structure enabling high production cycles while maintaining sealing and cutting accuracy
• Adjustable process parameters via touch panel for rapid changeover between hollow-profile types, thicknesses and sizes
• Optional modules for fully automatic lines including feeding, cutting and pallet stacking
• Industrial router and BI-BOX interface for remote access, data sharing and integration with MES/ERP
• Capable of processing sheets with high recycled polypropylene content (up to 80%)

Advantages of sealing hollow profiles

• Increased compression and torsion resistance: trapped air in sealed cavities can raise mechanical resistance up to +40%, enabling weight reduction per m² without losing strength
• Improved thermal insulation: internal air cavities act as insulating barriers
• Aseptic performance: sealed cavities prevent ingress of bacteria, dust and liquids, critical for food and pharmaceutical packaging
• Reusability: sealed hollow-profile components are easy to clean and can be reused multiple times
• Recyclability: absence of contaminants in sealed cavities simplifies cleaning and reintroduction into recycling streams
• Eco‑sustainability: process supports sealing of sheets with high recycled content (up to 80%) without compromising speed or quality
