Upgrading a Snack Producer’s Packing Line for 100% Paper-Based Cans
In support of a major sustainability initiative, Contec contributed to the complete rebuild of a packing line at a snack production site. The project aimed to replace traditional mixed-material cans with fully recyclable paper-based packaging, aligning with modern environmental and operational standards.
To enable this transition, outdated equipment was replaced and integrated with new machines across the entire line, including a paper-bottom can sealing system. Contec ensured seamless electrical and automation integration, including safety logic and start-up support.
Key Outcomes:
-
Transitioned to 100% recyclable paper-based cans
-
Seamless integration of all new line equipment
-
Safety logic implemented and validated
-
Electrical design and on-site commissioning delivered on time
The challenge
Integrating new sustainable packaging technology into a high-speed production environment
To rebuild and integrate a complex high-speed packaging line to handle new, more delicate paper-based cans, without compromising efficiency or safety. The project required close coordination between OEM systems and existing site infrastructure.
Our approach
A full-scope engineering delivery from design to production readiness
To ensure a successful transition to sustainable packaging, Contec delivered a comprehensive electrical engineering solution, covering every phase from concept design to commissioning, start-up and production qualification.
This full-scope approach included:
- Replacement of the Can Filler to ensure fast, accurate chip dosing
- Integration of new conveyor systems across all line stages
- Implementation of a Flexible Case Collation system for sensitive paper cans
- Integration of infeed and outfeed conveyors for the Case Packer and palletizing
- Adaptation of the Online Case Printer to new case specifications
- Development of a Cause & Effect matrix and implementation of safety logic
- Electrical design in EPLAN, including integration of OEM equipment with plant infrastructure
- On-site panel modifications, cable connections, and OEM interface support
- IQ/OQ support, troubleshooting, and assistance during production qualification
