Nguyen Van Minh manages a Vietnam packaging factory in Ho Chi Minh City. The factory produces plastic bags, cardboard boxes, and food packaging for local manufacturers. Before 2024, Nguyen used pre-printed labels for dates and batch numbers.
Pre-printed labels caused three problems: high cost ($1,200/month), slow application (2 workers spent 4 hours daily), and inflexibility (label changes required new print runs). In January 2024, Nguyen invested in a handheld inkjet printer for direct coding on packaging.
Within 1 month, the Vietnam packaging factory eliminated label costs and reduced coding labor by 80%. The case study reveals the exact investment, cost savings, ROI, and applications of the industrial inkjet printer.
Problem with Pre-Printed Labels
Before purchasing the batch coding machine, Nguyen's factory faced issues:
Cost: Pre-printed labels cost $0.02 each. Factory used 60,000 labels monthly = $1,200/month.
Labor: 2 workers spent 4 hours daily applying labels. Total labor: $500/month.
Inflexibility: Changing date or batch number required new label rolls with 3-5 day lead time.
Waste: Misprinted label rolls caused $$100$$150 monthly waste.
Nguyen researched alternatives including continuous inkjet printers, laser coders, and handheld inkjet printers. The handheld inkjet printer offered best balance of cost and flexibility.
Equipment Investment
Nguyen selected a portable handheld inkjet printer with these specs:
12.7mm print height (handles standard date and batch codes)
Water-based and solvent ink compatibility
3.5-inch touchscreen for message editing
Built-in battery for 8-10 hours use
Supports text, numbers, barcodes, and QR codes
Total investment:
Handheld inkjet printer: $650
Spare ink cartridges (2): $80
Spare battery: $50
Shipping: $40
Total: approximately $820
Applications and Usage
The Vietnam packaging factory uses the date coding printer for multiple applications:
Production date coding on food packaging (20,000+ prints/month)
Batch number coding on cardboard boxes (15,000+ prints/month)
Expiry date coding on cosmetic packaging (10,000+ prints/month)
QR code printing for traceability (5,000+ prints/month)
The industrial inkjet printer prints directly on plastic, cardboard, glass, metal, and wood. Solvent ink dries in 1-2 seconds and resists smudging.
One worker operates the handheld inkjet printer 2 hours daily, replacing 2 workers who spent 4 hours applying labels. The batch coding machine enables on-demand message changes.
Cost Savings and ROI
After 3 months, Nguyen calculated savings:
Monthly savings:
Eliminated pre-printed label cost: $1,200
Reduced labor from 2 workers to 1 part-time: $350
Eliminated label waste: $120
Total: approximately $1,670
Monthly costs:
Net monthly savings: $1,570
ROI:
Nguyen recovered the entire investment within the first month of using the industrial inkjet printer.
Challenges and Solutions
Vietnam packaging factory owners face unique challenges with industrial inkjet printers:
Humidity: Ho Chi Minh City has high humidity (70-85%). Nguyen uses solvent ink for better adhesion.
Ink availability: Finding compatible ink locally was difficult. Nguyen orders ink in bulk with 1-week shipping.
Worker training: Workers had no experience with date coding printers. The supplier provided 1-hour video training.
Next Steps
Nguyen's story demonstrates how a handheld inkjet printer can transform packaging operations and deliver rapid ROI. The industrial inkjet printer eliminated $1,200+ monthly label costs, reduced labor, and improved coding quality.
