Sobres C5 autoadhesivos MAILmedia 35133/7, papel reciclado marrón, 90 g/m², paquete

MAILmedia self-adhesive C5 envelopes (brown recycled paper, 90 g/m²) are designed to carry A5 documents and similar flat items securely and efficiently. Made from recycled kraft-style paper with a natural brown finish, these envelopes come with a peel-and-seal closure that removes the need for moistening or additional sealing tools. The paper weight of 90 g/m² provides a balance between flexibility and durability, protecting contents during handling and transit while maintaining a lightweight profile for postage efficiency.

Advantages

These envelopes combine environmentally conscious materials with practical features: recycled brown paper reduces the use of virgin fibers, while the 90 g/m² weight gives improved resistance to tearing and creasing compared to thinner alternatives. The self-adhesive peel-and-seal strip enables fast, one-handed sealing and a consistent closure. The neutral brown appearance is suitable for business and everyday mailings, offering a simple, professional look without additional packaging.

Suitable for

• Mailing A5 documents, letters and brochures
• Office correspondence and internal distribution
• Invoices, statements and printed materials
• Small catalogs, promotional inserts and samples

Key specifications

• Format: C5, fits A5-size documents
• Material: recycled brown paper (kraft appearance)
• Paper weight: 90 g/m²
• Closure type: peel-and-seal self-adhesive strip
• Color: natural brown

How to use

Insert A5 documents or other flat contents into the envelope so they lie flat without overfilling. Remove the protective strip from the adhesive flap and press firmly along the flap to ensure a secure seal. For heavier contents, press the edges and center of the flap for even adhesion. Do not attempt to reseal once the adhesive has been bonded, as this can reduce seal strength.

Recommendations

Store envelopes in a dry, cool place away from direct sunlight to preserve adhesive performance and paper integrity. Avoid overfilling beyond the flap’s capacity to prevent tearing or incomplete sealing. For items requiring extra protection, pair the envelope with an inner protective sleeve or use additional packing such as rigid mailers or cardboard inserts.
