Fingerprint Backing Cobex/Acetate Sheets

Clear, anti‑static backing sheets designed to protect adhesive or rubber lifters without distorting detail. The sheets shield the lift surface during handling and storage, helping preserve ridge clarity from the crime scene to the lab. Supplied in multiple sizes to suit finger, palm, footwear and tyre impressions.

Advantages

• Anti‑static surfaces to reduce dust attraction and preserve lift quality.
• Optical clarity for unobstructed examination and photography.
• Robust film that resists creasing and abrasion in kits and wallets.
• Size options from compact finger lifts to 177.8 × 355.6 mm footwear formats (metric below).
• Compatible with adhesive‑tape lifts and rubber/gel lifters.

How it works

After you’ve made the lift, cover it with a backing sheet (or sandwich the lift between two sheets). The film protects the adhesive face from contamination and abrasion and keeps the surface flat for lab work and archiving.

Key specifications

• Material: clear Cobex/acetate‑type film (anti‑static).
• Thickness: typically ≈ 175 µm (selected sizes); other thicknesses may be available.
• Packs: commonly 100 sheets per pack (size‑dependent).
• Sizes:
  • ≈ 88.9 × 127 mm
  • ≈ 101.6 × 127 mm (typ. 175 µm)
  • ≈ 101.6 × 152.4 mm (typ. 175 µm)
  • ≈ 177.8 × 355.6 mm (footwear/tyre)

Typical applications

Latent print lifts (finger/palm), footwear and tyre impressions, ear and toolmark lifts, evidence packaging and archiving.

FAQs

Are both sides anti‑static?

Selected SKUs are treated both sides to minimise static; confirm on order if this is critical to your process.

Can we order other sizes or thicknesses?

Yes, custom sizes/thicknesses can usually be supplied.

Do these sheets replace backing cards?

No, they protect your lift; use backing cards when you also need case information on the mount.
