Question 1

Is dry ice cleaning safe for anilox rollers and will it damage the cells?

Accepted Answer

Yes, dry ice cleaning is completely safe for anilox rollers and is actually the preferred method by many press operators and roller manufacturers. Unlike ultrasonic cleaning or aggressive chemical cleaning that can erode cell walls over time, dry ice cleaning is non-abrasive and won't damage the microscopic engraved cells. The dry ice pellets are softer than the ceramic or chrome surface of the roller, and they sublimate (turn from solid to gas) upon impact, so there's no abrasive media left behind. The process works through thermal shock—the -109°F dry ice causes dried ink and coatings to contract and release from the cells without mechanical abrasion. We've successfully cleaned thousands of anilox rollers across all cell counts (from 200 to 1200+ lines per inch) and all engraving types (mechanical, laser, chemical) without any damage. In fact, dry ice cleaning often restores cell volume to 95%+ of original capacity, which is better than most other cleaning methods. The process is so gentle that it's safe for even the finest cell counts used in high-quality flexographic printing. Many printing companies have adopted dry ice cleaning as their standard maintenance procedure specifically because it extends roller life and maintains print quality better than traditional methods. We follow manufacturer guidelines and best practices to ensure optimal results without any risk of damage.

Question 2

How much downtime is required for press cleaning and can you clean during operation?

Accepted Answer

Dry ice cleaning significantly reduces press cleaning downtime compared to traditional methods. A typical press cleaning that would take 8-16 hours with manual scrubbing and solvents can be completed in 2-4 hours with dry ice cleaning. This is because there's no disassembly required—we clean rollers, cylinders, ink systems, and other components in place. There's also no drying time since the process is completely dry, so the press can return to production immediately after cleaning. For some components and applications, we can even clean during operation at reduced speeds, which further minimizes downtime. For example, we can clean ink mist and paper dust from web press components while the press is running, and we can clean some packaging line components during changeovers. The exact downtime depends on the size and type of press, the level of contamination, and whether a full cleaning or targeted cleaning is needed. Most flexographic presses can be cleaned in 3-4 hours, offset presses in 4-6 hours, and packaging lines in 2-3 hours. We work with your production schedule to minimize impact—many facilities schedule cleaning during planned maintenance windows, shift changes, or weekends. The reduced downtime means you can clean more frequently to maintain optimal print quality and equipment performance, rather than waiting until contamination causes quality issues or equipment problems.

Question 3

What types of printing and packaging equipment can you clean?

Accepted Answer

We can clean virtually all types of printing and packaging equipment, including flexographic presses (narrow web, wide web, and CI presses), offset presses (sheetfed and web), digital printing equipment, gravure presses, screen printing equipment, and letterpress equipment. For packaging lines, we clean filling machines, capping equipment, labeling machines, cartoning equipment, case packers, palletizers, and conveyor systems. Specific components we clean include anilox rollers (all cell counts and types), print cylinders and plates, doctor blades and chambers, ink fountains and distribution systems, impression rollers, transfer rollers, coating systems, drying systems, web guides and tension controls, die cutters and rotary dies, folder-gluers, and glue application systems. We also clean facility infrastructure like ventilation systems, electrical panels, and production floors. The process is safe for all materials commonly used in printing and packaging equipment—steel, aluminum, chrome, ceramic, rubber, and plastics. We have experience with equipment from all major manufacturers including Mark Andy, Bobst, Heidelberg, Komori, HP Indigo, and many others. Whether you're running a small commercial print shop or a large-scale packaging plant, we have the expertise and equipment to handle your cleaning needs. We can also provide regular maintenance cleaning programs to keep your equipment running at peak performance.

Question 4

How does dry ice cleaning improve print quality and reduce waste?

Accepted Answer

Dry ice cleaning improves print quality by removing contaminants that cause common printing defects. Dried ink, coatings, and adhesive buildup on anilox rollers reduces cell volume and causes uneven ink transfer, leading to streaking, light spots, and color inconsistency. Contamination on doctor blades causes blade chatter and streaking. Buildup on impression rollers and transfer rollers causes ghosting and poor registration. By thoroughly cleaning all these components to factory specifications, dry ice cleaning restores consistent ink transfer, eliminates streaking and ghosting, improves color consistency, and ensures proper registration. This directly reduces waste from rejected prints, reduces setup time and makeready waste, improves first-run quality, and extends the time between press adjustments. Many printing companies report 15-30% reduction in waste after implementing regular dry ice cleaning maintenance. The improved print quality also means fewer customer complaints and reprints, which saves both materials and labor costs. For packaging applications, clean equipment ensures proper adhesive application, accurate label placement, and consistent seal quality, which reduces rejected packages and product recalls. The investment in regular dry ice cleaning typically pays for itself within 2-3 months through reduced waste and improved efficiency. Many facilities schedule monthly or quarterly cleaning to maintain optimal performance.

Question 5

Is dry ice cleaning approved for food packaging equipment and FDA compliance?

Accepted Answer

Yes, dry ice cleaning is fully approved for food packaging equipment and meets FDA, USDA, and EPA standards for food contact surface cleaning. The process uses food-grade CO2 (the same CO2 used in carbonated beverages) and leaves no chemical residue, making it ideal for cleaning equipment that comes into contact with food products. Unlike chemical cleaning that can leave residues that contaminate food or require extensive rinsing and validation, dry ice cleaning is completely dry and chemical-free. The CO2 pellets sublimate (turn from solid to gas) upon impact, so there's no cleaning media left behind to contaminate products. This makes dry ice cleaning the preferred method for many food packaging facilities because it eliminates the risk of chemical contamination while providing superior cleaning results. We can clean filling machines, capping equipment, labeling systems, and conveyor belts that handle food products without any risk of contamination. The process is also effective at removing biofilms, mold, and bacteria that can develop on food contact surfaces, which helps maintain sanitary conditions and pass food safety inspections. Many food packaging facilities use dry ice cleaning as part of their HACCP (Hazard Analysis and Critical Control Points) programs to ensure food safety. We provide documentation and validation reports that can be used for regulatory compliance and audit purposes. The process is also safe for pharmaceutical packaging equipment that requires cleanroom standards and GMP compliance.

Question 6

What are the cost savings compared to traditional press cleaning methods?

Accepted Answer

Dry ice cleaning provides significant cost savings across multiple areas. First, reduced downtime means more production time—cleaning a press in 3 hours instead of 12 hours means 9 additional hours of production, which can be worth $5K-$20K+ depending on your production rates. Second, extended equipment life—properly maintained anilox rollers can last 3-5 years longer, avoiding $15K-$50K replacement costs per roller. Third, reduced waste from improved print quality saves 15-30% on materials and reduces rejected prints. Fourth, eliminated chemical costs—no need to purchase solvents, degreasers, or disposal services, saving $5K-$20K annually. Fifth, reduced labor costs—cleaning is 75% faster and requires fewer workers. Sixth, improved efficiency—clean equipment runs faster with fewer stops for adjustments. When you add up all these savings, most printing and packaging facilities see ROI within 3-6 months of implementing regular dry ice cleaning maintenance. For a typical mid-size printing operation, annual savings can range from $50K to $200K+. The savings are even greater for large packaging plants with multiple lines. Many facilities start with quarterly cleaning and then move to monthly cleaning once they see the results and cost savings. We can provide a detailed cost analysis based on your specific equipment, production schedule, and current cleaning methods to show exactly how much you can save.
