What is micro shredding?
Micro shredding refers to the highest level of document security available in consumer and office shredders. Micro-cut shredders slice paper into extremely small particles—typically measuring around 2mm x 10mm or smaller—making it nearly impossible to reconstruct the original document.
Compared to standard cross-cut or strip-cut methods, micro shredding provides superior protection against data recovery. The tiny confetti-like pieces are often so small that even advanced forensic techniques struggle to reassemble them.
This level of security is recommended for:
- Legal and medical offices handling sensitive client data
- Financial institutions and accounting firms
- Government agencies and defense contractors
- Businesses complying with strict data protection laws
What is the difference between cross cut and strip cut?
The key difference lies in the cutting mechanism and resulting security level:
- Strip-Cut Shredders: Cut paper into long, narrow strips (typically 3–6mm wide). While effective for basic disposal, these strips can be manually reassembled, making them less secure. Best suited for non-sensitive documents.
- Cross-Cut Shredders: Use a two-dimensional cutting action that slices paper both vertically and horizontally, producing small rectangular or diamond-shaped particles. This significantly increases security by making reconstruction extremely difficult.
For example, a single letter-sized page shredded with a strip-cut machine might yield 10–12 long strips. The same page processed through a cross-cut shredder could produce over 200 small pieces, greatly reducing the risk of information recovery.
Expert Advice: For home offices or small businesses, cross-cut shredders offer the best balance of security and capacity. For maximum protection—especially with financial or legal documents—consider upgrading to a micro-cut model.
