Chapter 1: What are Tamper Proof Bags?

Tamper-evident bags play a crucial role in securing crime scene evidence. Constructed from durable, leak-resistant polyethylene, these bags resist tears and punctures while featuring strong adhesive seals to securely contain their contents.

In modern eCommerce, courier bags have become essential. Tamper-proof courier bags provide businesses with professional, secure packaging solutions that optimize shipping and storage processes. Courier services and logistics providers frequently use these bags to transport semi-fragile items including electronics, jewelry, and watches.

Self-adhesive or heat-seal technologies enhance sealing efficiency, while integrated pod jackets eliminate the need for separate document attachments. This creates cost-effective solutions for bulk custom designs. Additionally, courier bags serve as excellent branding tools, allowing direct printing of promotional content to increase brand visibility.

Tamper-proof courier bags feature hot-melt adhesive strips that prevent undetected opening. Made from co-extruded film, these recyclable bags resist oils, water, and rough handling. A clear pod jacket on the back provides convenient space for waybills, addresses, and important documents.

Chapter 2: What are Evidence Bags and How Are They Used?

Evidence bags serve as specialized containers for collecting, transporting, and preserving physical evidence in forensic investigations and legal proceedings. Manufactured from high-quality paper or durable plastic, these bags protect various evidence types while maintaining integrity crucial for court admissibility.

Modern evidence bags feature writable panels for recording chain of custody details, including case information, collection details, and recovery locations. Proper documentation ensures secure handling and prevents tampering allegations in legal processes.

Forensic best practices recommend storing individual items separately to minimize cross-contamination. While similar items may be grouped, most evidence requires separate bags with unique identifiers for accurate tracking during analysis and court presentation.

Reasons for Using Tamper-Evident Bags (TEB)

Law enforcement and forensic labs require TEBs to securely handle evidence during investigations. These bags:

• Maintain chain of custody from collection to courtroom

• Work in clean, controlled environments
• Use sanitized surfaces to prevent contamination

When inserting items, expand the bag and turn it inside out to handle evidence without touching the exterior. After placement, arrange contents for visibility and seal securely while documenting all procedures.

How to Seal a TEB

Follow these steps for proper sealing:

1. Place the TEB on a clean surface
2. Hold the orange security strip edge
3. Peel back the blue strip to expose adhesive
4. Press the strip firmly for complete bonding

document the sealing process with time, date, and responsible personnel information.

When to Use a TEB

Use TEBs for all seized property and evidence collection, especially in cases requiring strict chain of custody. Handling protocols include:

• Special containers for oversized items
• Puncture-proof secondary packaging for sharp objects
• Paper bags for clothing preservation
• Double-bagging for cash and biological samples
• Breathable bags for moist evidence
