Printing & Laminating
Gravure, flexible packaging, lamination, optical film and continuous web processes.
Processes and emission sources
Typical trains use zeolite concentration ahead of RTO or catalytic oxidation, sized to line airflow and dryer duty.

How we turn printing & laminating exhaust data into a treatment train
The recommended configuration is built around the actual production process, not a generic industry label. This is especially important when one site has multiple exhaust headers, recipes or operating modes.
Common treatment challenges
- Large airflow with relatively low solvent concentration
- Changing ink/solvent recipes across SKUs
- Heat recovery opportunities on drying lines
Data we request
- Exhaust source, airflow and operating schedule
- VOC/pollutant analysis, concentration range and LEL information
- Temperature, humidity, dust, mist and corrosive components
- Existing collection or pretreatment equipment
- Emission target, layout, utilities and shutdown constraints
Engineering decisions
- Whether streams should be segregated, balanced or treated together
- Which pretreatment protects downstream equipment
- Whether concentration, direct oxidation, recovery or polishing is appropriate
- Materials, safety interlocks, monitoring and maintenance access
- Where recovered heat or utilities can be integrated
Recommended path for printing & laminating exhaust
This is a decision framework based on the supplied product and project material. The final train changes with measured chemistry, operating patterns and site constraints.
Common emission sources
- Printing press and ink-drying exhaust
- Laminating and adhesive application
- Coating oven and web dryer exhaust
- Cleaning/solvent-handling points
Dry filtration → zeolite concentration → RTO or catalytic oxidation
Large dryer airflow and relatively dilute solvent loading often make concentration worth evaluating before destruction. The oxidizer is selected from solvent chemistry, load variation and heat-reuse opportunity.
- 01Map each dryer/press header and solvent recipe
- 02Remove particulate and sticky contamination
- 03Concentrate compatible VOCs
- 04Destroy the smaller concentrated stream
- 05Recover heat where the production process can use it
Direct RTO with heat recovery
Consider when inlet VOC load/heat value, space, process continuity and energy balance support direct thermal oxidation without a concentrator.
Process-specific questions
Why separate printing and lamination exhaust?
Different solvent mixes, temperatures and airflow patterns can affect safety, treatment efficiency and energy use. Segregation is assessed before final duct and treatment design.
Can dryer heat be reused?
Possibly. Heat reuse is assessed against temperature demand, contamination risk, operating schedule and the approved heat balance.
