DRY ICE BLASTING & SPECIALIST INDUSTRIAL CLEANING
Graphic Packaging - Fishponds, Bristol, BS37
Client's Challenge
Graphic Packaging invited APT ICC to carry out a site survey and propose a specialist programme of industrial deep cleaning and dry ice blasting at their Bristol packaging and printing plant.
Following an internal audit, multiple areas of contamination build-up were identified, particularly in difficult-access areas within and beneath printing presses. These issues were negatively affecting housekeeping standards and hindering wider continuous improvement initiatives across the production environment.
The client’s objectives were to:
• Improve overall cleanliness and hygiene standards
• Reduce contamination-related downtime
• Support safer working conditions around printing press machinery
A key challenge was that a previous dry ice blasting contractor had delivered poor results at significant cost, creating understandable concern about repeating the process. In addition, the presses typically operated continuously, meaning the works had to be delivered within a tightly controlled shutdown window to avoid operational disruption.
Assessment & Planning
APT ICC carried out a detailed on-site survey to assess:
• The contamination
highlighted during the internal audit
• High-risk and difficult-access areas within printing press assemblies
• Suitable shutdown windows and sequencing to minimise downtime
• The most effective combination of dry ice blasting and degreasing methods
• How to demonstrate clear improvement following a previously unsuccessful contractor attempt
To reduce risk and build confidence, APT ICC proposed a controlled two-day dry ice blasting trial, working alongside the client’s site team. Following successful validation of results, the Bristol site management approved immediate progression to the full scope of works.
Methodology
1. Dry ice blasting trial and validation
A two-day trial demonstrated safe, controlled dry ice blasting on press components, addressing concerns from previous contractor experience.
2. Dry ice blasting of internal press component
Specialist cryogenic technicians cleaned internal areas including rollers and gearing. Dry ice blasting was selected for its non-abrasive, residue-free properties.
3. External press cleaning and degreasing
Oils, grease, and surface contamination removed from external press areas using controlled industrial degreasing and wipe-down methods.
4. Deep cleaning beneath presses and
surrounding areas
Removal of debris, dust, and paper fibres to improve hygiene and reduce contamination transfer risk.
5. Industrial floor cleaning support
Where required, degreasing solutions were used in conjunction with scrubber dryers to restore floor condition within operational zones.
Site Access & Logistics
Equipment
• Specialist cryogenic dry ice blasting systems
• Industrial cleaning and access equipment for press environments
Chemicals
• UltraMax 2020 – industrial parts washer degreaser / ultrasonic cleaner concentrate, used for external press degreasing and industrial floor cleaning support.
Dry Ice Blasting Notes
Dry ice blasting was used as a chemical-free cleaning method for internal press components. CO₂ pellets sublimate on impact, leaving no solid blasting residue.
The Results
• Difficult-access areas identified during audit fully restored
• Successful dry ice blasting of rollers,
gearing, and internal press components
• Improved housekeeping standards beneath and around presses
• Reduced contamination risk and safer working environment for operators
• Works completed within a tightly controlled shutdown window
• Minimal disruption and no unplanned downtime
Following the success of the programme, APT ICC was awarded an ongoing planned works programme to support continued improvement and phased upgrades across the facility.
