Environmental Performance Evaluation of Color Steel Plate Protective Films
To judge the environmental performance of color steel plate protective film, you can start from certification, material, glue, odor, degradability and other aspects to quickly identify whether the product is environmentally friendly.
1. Check Certification Marks
Verify if the product has authoritative environmental certifications which are important endorsements of its environmental performance.
- China Ten Ring Certification
- EU REACH Regulation Certification
- RoHS Directive Certification
- If no relevant certification exists, choose carefully
2. Identify Material Composition
The base material determines the fundamental environmental characteristics of the protective film.
- Preferred: PE (polyethylene) and PET (polyethylene terephthalate) - safe and odorless
- Avoid: PVC materials (may release harmful substances at high temperatures)
- Check if recycled materials are used (less environmentally friendly)
3. Confirm Glue Type
The adhesive composition significantly impacts environmental performance.
- Water-based glue: Most environmentally friendly, low VOC content
- Solvent-based glue: May contain benzene/formaldehyde
- Ensure VOC content meets national standards (≤1000g/L)
4. Smell & Residue Observation
Immediate sensory evaluation can reveal potential environmental issues.
- Pungent odor indicates possible excessive harmful substances
- High-quality films should leave no glue stains when peeled
- Excessive residue suggests non-environmentally friendly glue
5. Degradability Assessment
End-of-life environmental impact is crucial for true sustainability.
- Ask if product is degradable
- Some contain photo-oxidation degradation masterbatch
- Request third-party degradation performance test reports
6. Verify Production Process
Manufacturing methods affect the overall environmental footprint.
- Preferred: Solvent-free compounding and UV curing
- Check if manufacturer has VOC treatment equipment
- Review environmental impact assessment reports
By systematically evaluating these six aspects, you can effectively identify truly environmentally friendly protective films for color steel plates.
