Mailing bags MAILmedia Securitex DIN C4 with 5.0 cm gusset, white — pack of 100

MAILmedia Securitex DIN C4 mailing bags with a 5.0 cm gusset in white, supplied as a pack of 100, are designed to transport documents, brochures and other flat items securely and efficiently. The bags fold flat for compact storage and expand at the gusset to hold thicker contents without compromising the outer dimensions. Constructed for routine postal, office and e‑commerce use, they combine simple handling with a clean white appearance suitable for professional correspondence.

Advantages

These Securitex mailing bags offer a balance of durability and flexibility: the 5.0 cm gusset allows for thicker stacks or small product bundles while the fold‑flat design reduces warehouse and shelf space when not in use. The white exterior provides a uniform printable surface for labeling or adding shipping stickers. The pack of 100 ensures consistent supply for regular mailing needs and helps standardize handling processes in offices and fulfillment operations.

Suitable for

• Mailing A4 and folded A4 documents in DIN C4 format
• Sends of brochures, catalogues and thin booklets
• Packaging small, flat retail items for e‑commerce orders
• Office and administrative dispatches requiring neat presentation

Key specifications

• Size: DIN C4 format, suitable for unfolded A4 documents
• Gusset width: 5.0 cm for increased internal capacity
• Color: white exterior
• Pack quantity: 100 bags
• Design: fold‑flat for space‑efficient storage; expands at gusset for thicker contents

How to use

Insert documents or items into the open end of the mailing bag and allow the gusset to expand to accommodate the thickness. Ensure contents lie flat and are aligned with the bag edges to minimize bulk. Close and seal according to the bag's closure system or use appropriate adhesive or tape if required. Affix any shipping labels, address details or handling marks to the exterior surface, keeping them clear of seams and the closure area.

Recommendations

Store the bags flat in a dry environment away from direct sunlight to preserve material performance. For heavier or three‑dimensional items use additional internal padding or a different packaging type; verify that the combined thickness does not exceed the gusset capacity. When preparing bulk mailings, prelabeling or batching items before insertion can speed up processing and ensure consistent presentation.
