Mailing bags MAILmedia C13 Brown 15 g, size 170 x 225 mm, pack shipping envelopes

MAILmedia C13 Brown mailing bags are lightweight polyethylene shipping envelopes measuring 170 x 225 mm and weighing 15 g. Designed for sending documents and small items, these brown mailers combine a thin but durable film with a tamper-evident adhesive strip to secure contents during transit. The compact size is suitable for folded papers, small booklets, cards and low-volume e‑commerce orders where economical, space-saving packaging is required.

Advantages

The polyethylene construction offers moisture resistance and basic puncture protection while keeping package weight low to reduce postage costs. The self-seal adhesive closure provides a quick, single-step sealing process and a visible indication if the bag has been opened. The neutral brown colour conceals contents and presents a consistent, low-profile appearance for shipping and returns. These envelopes are stackable and take up little storage space before use.

Suitable for

• Sending documents such as invoices, letters and certificates
• Mailing small flat items: cards, brochures, labels
• E‑commerce orders of small, lightweight products
• Retail returns and customer exchanges
• Organising and protecting paperwork during transit

How to use

Place the items to be shipped inside the MAILmedia C13 mailing bag, ensuring contents are flat and do not exceed the envelope dimensions.

Usage recommendations

Use these mailing bags for lightweight, non-fragile items and documents. Do not use for heavy, sharp or highly valuable items without additional protective packaging. Store the envelopes in a dry, shaded area to preserve the adhesive performance and material integrity.
