Envelope Office Products C6 transparent, pack 500 – courier/return sleeve

Transparent C6 envelopes from Office Products are lightweight courier and return sleeves designed to hold C6-format documents and small items. Supplied in a pack of 500, these transparent sleeves provide a simple way to protect, identify and present inserts during shipping, returns handling, or office filing without obscuring the contents. The clear material allows recipients and handlers to see invoice numbers, address labels or document summaries at a glance while keeping papers shielded from light scuffs and moisture.

Advantages

The transparent construction makes content identification quick and reduces the need to open packages during sorting. The sleeves are thin and flexible for easy stacking and efficient storage, yet durable enough for short-term handling in postal and courier workflows. Supplied in a large pack of 500, they support high-volume operations and help standardize return or dispatch processes.

How to use

Insert the C6-format document, invoice or return slip into the sleeve so that key information is visible through the transparent film. Attach or affix the sleeve to the outside of a parcel or place it inside a package near the contents as required by your shipping procedure. For returns, include the appropriate return label or form in the sleeve before sealing the parcel. Store unused sleeves flat in their pack to maintain shape and prevent creasing.

Usage recommendations

Use with adhesive tape or parcel-safe fastening methods to secure the sleeve to outer packaging. Avoid prolonged exposure to direct sunlight or high humidity if paper legibility must be preserved over time.
