Poly Mailer/ Courier Bags
Qline poly mailer courier bags are crafted from premium co-extruded polyethylene film with a black inner layer for added confidentiality and a white outer surface for clear labeling and branding; transparent options are also available. Each bag is fitted with a peel-and-seal hot-melt adhesive strip that delivers a secure, tamper-evident closure — any attempt to open the package will cause visible damage such as tearing or cutting. A clear overlapping document pouch is provided on one side to hold shipping labels, invoices, or consignment notes for smooth and protected transit.
Qline courier bags are widely used by e-commerce businesses, courier services, and logistics companies for safe and reliable shipping.
Qline courier bags are commonly used by online retailers, couriers, and logistics organizations.

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.

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).
