## Long description

MAILmedia K-Pack C4 is a white protective mailing bag manufactured from a 360 g/m² material and sized to accommodate C4-format documents without folding. The envelope is intended to safeguard letters, certificates, brochures and other flat items during postal transit by providing resistance to bending and reduced exposure to moisture. Its reinforced construction helps maintain the integrity of contents and supports both business and private mailing needs.
Advantages
The mailing bag combines a rigid 360 g/m² board-like material with a smooth outer surface to deliver dimensional stability and corner protection for documents. Its C4 size fits A4 sheets flat, eliminating the need to fold important papers. The white finish offers a clean appearance suitable for professional correspondence, while the robust material reduces the risk of creasing and light moisture ingress during handling and transport.
Suitable for
Shipping A4 documents, certificates and contracts without folding
Mailing brochures, thin catalogs and promotional materials
Sending photos, prints and flat artwork that require rigid support
Business correspondence and private letters that need added protection
Key specifications
Format: C4 — sized for flat A4 documents
Material weight: 360 g/m² — rigid, protective board-like construction
Color: white — professional, neutral appearance
Type: protective mailer envelope designed for postal use
Intended use: protection against bending and light moisture during shipment
How to use
Insert flat documents or items into the open end of the MAILmedia K-Pack C4 so that contents lie flat within the envelope. Close the envelope according to the product's closure method (adhesive strip or flap) and ensure the seal covers the full width of the opening. For added security, use a clear shipping label or write the recipient address on the surface, avoiding placement over seams. Place any required postage and handling markings on the front face prior to dispatch.
Usage recommendations
For best results, avoid overfilling beyond the envelope’s flat capacity; do not insert bulky or heavy items that exceed the protective properties of a rigid mailer. When sending items sensitive to moisture, consider combining the C4 mailer with an internal plastic sleeve or using additional external packaging for long-distance transit.
