Solvent-Free Lamination Retrofit for a Major Flexible-Packaging Enterprise
Background
In response to national environmental policies, this enterprise converted 5 dry-lamination lines to solvent-free lamination, supported by Gluexpert solvent-free two-component mixing machines, achieving both lower adhesive cost and greener production.
Key Concerns
- Environmental compliance: eliminate solvent emissions to meet local environmental requirements;
- Cost control: solvent-free adhesive is cheaper per unit with lower coating weight;
- Stable quality: initial tack and curing control are critical.
Solution
The GB-SF series solvent-free two-component mixing machine uses precision metering pumps and static mixing, with ratio accuracy of ±2%, and supports a "mix small, mix often" produce-on-demand mode.
Solution Highlights
- Zero solvent emissions: no drying tunnel needed, energy use drops accordingly;
- 50% lower adhesive cost: precise coating weight with minimal waste;
- Seamless integration: signal-linked with existing laminators;
- Data management: batch-level traceability.
Results
- Adhesive cost cut by 50%, with substantial annual savings;
- Solvent emissions reduced to zero, passing environmental inspection;
- Retrofit investment recovered in 8 months.
