Rohrer AG will present the latest ultrasound technology for flexible foils at the Interpack. Packaging machines with SonoCut technology are ideal for cutting and sealing tubular bags and perforating FFS multipacks.
A high-precision punching tool is an efficient alternative when thermal processes or classic tubular pouch machines are pushed beyond their limits. SonoCut technology is perfect for processing modern ecological materials and ultra-thin foils and enables ever more complex packaging designs.
Alternative laminates
SonoCut makes you independent from PS films as it can create break lines even on new alternative film laminates such as PP, PET and PLA. Multiportion packs made of flexible plastics and laminates were previously inconceivable. FFS multipacks made of PET, for instance, are now a reality thanks to SonoCut. The technology enables cutting and sealing combinations to produce and seal individual peelable films on packaging using ultrasound. Inexpensive films keep costs low, recyclable plastics improve the ecobalance and stable processes increase production reliability.
New solutions
Combining ultrasound with a precision tool enables a whole new range of packaging solutions. The ultrasound components are integrated in the mechanical structure where they form an autarkic unit. SonoCut is ideal for cutting and sealing thin film laminates for the production of tubular packaging. It creates air-tight packaging even if the seal surfaces are soiled or contaminated. SonoCut retrofit components are ideal for integration in existing systems due for refurbishing.
Advantages
Ultrasound sealing processes offer significant advantages in comparison to thermal methods with regard to horizontal and vertical tubular bag packaging lines:
- Air-tight seals even when the seal is contaminated with pasty, fine-ground or
light-weight products (e.g. sauces, cheese or fresh salad)
- Gentle treatment of sensitive products through less heat transfer
- Saves packaging material through less dead space and more compact seals
- Air-tight seals, higher cycles times, better productivity and less cost
Safety through testing
A test rig makes it possible to map production processes for scalable market implementation. Reproducible preliminary studies on modern test equipment minimise risk and support efficient implementation in the production environment.
