Mailing carton shipping bags ColomPac CP010.04.020 — pack of 20

ColomPac CP010.04.020 mailing carton shipping bags come as a pack of 20 rigid cardboard mailing envelopes designed to protect documents and small items during transport. These lightweight carton shipping bags combine the convenience of a mailer with the protective qualities of cardboard, offering a flat, supportive packaging solution that resists bending and provides cushioning when used with appropriate internal padding. They are suitable for use in e-commerce order fulfillment, returns processing and postal deliveries where a slim but sturdy package is required.

Advantages

These carton shipping bags provide a rigid structure that reduces creasing and bending of contents, while remaining lightweight to help control postage costs. The consistent dimensions and uniform thickness make them easy to store and automate in packing workflows. Because they are made of cardboard, they are easy to write on and label, and they accept adhesive labels securely. The pack format of twenty pieces ensures a predictable stock level for small to medium-volume shippers.

Suitable for

• Sending documents, certificates and printed materials
• Shipping small, flat items such as thin books, photographs or accessories
• E-commerce order fulfillment and returns
• Postal and courier deliveries that require rigid protection

Key specifications

• Material: corrugated cardboard/mail-grade rigid carton
• Pack quantity: 20 pieces
• Form factor: flat mailing bag / carton envelope
• Protection level: rigid support against bending; suitable for light internal padding
• Labeling: writable surface compatible with adhesive labels and ink

How to use

Insert the document or item flat into the carton shipping bag, adding a thin protective layer such as bubble wrap or cardboard slip if additional cushioning is needed. Seal the open edge according to the bag design (fold-and-tuck or adhesive closure) and apply postage or a shipping label to the outer surface. Ensure the item is centered and does not extend beyond the edges to maintain rigid protection during handling.

Usage recommendations

For optimal protection, combine the carton shipping bag with a slim inner protective sleeve or corner boards for fragile corners. Choose an appropriate postage class based on combined weight and thickness; avoid overstuffing to maintain the bag's rigidity and to meet postal size requirements.
