Qline tamper-proof courier bags are manufactured using co-extruded polyethylene material with a black inner layer and white outer surface, along with transparent options. These bags come with a self-adhesive hot-melt flap that ensures quick sealing and creates a strong, permanent closure. Once sealed, the bag cannot be opened without tearing or cutting, making any tampering clearly visible. A clear POD pouch is provided on the surface for securely placing waybills, invoices, or consignment documents.
Qline courier bags are widely used by e-commerce businesses, courier services, and logistics companies for safe and reliable shipping.

Tamper Evident Bags
Qline tamper evident envelopes are designed with advanced security features that clearly indicate any unauthorized access. These envelopes provide instant and irreversible evidence if tampering is attempted, ensuring the safety of the contents.
They are produced using co-extruded polyethylene films with a black inner layer and white outer surface, along with transparent variants. Each envelope includes a hot-melt adhesive strip that allows quick sealing and creates a permanent, tamper-evident closure.
A special VOID security seal is integrated, which leaves visible marks when disturbed. Once sealed, the envelope cannot be opened without tearing or cutting, and any attempt to interfere results in clear VOID text transfer, confirming tampering.
These bags are widely used for transit of highly confidential documents, precious items like:
- Examination Papers.
- Passport.
- Evidence For Police Dept.
- Batch Samples.
- Credit/debit card.
- Currency.
- Confidential Documents.
- Aviation.
- Forensic Labs.

Bubble Bags
Bubble-lined courier bags add an extra layer of cushioning, helping to protect delicate and high-value items from damage during transit.
Tamper evident bubble bags are designed with enhanced security features that clearly show any attempt of unauthorized access, providing visible and permanent proof of tampering.
These bags are ideal for shipping valuable items such as mobile phones, jewelry, and other sensitive products where safety and tamper indication are critical.
They are available in two variants: hard bubble (where bubbles are directly formed on the film) and soft bubble (where bubble layers are laminated with the outer film during production).
