Mailing bag MAILmedia Jiffy Size 6 300 x 410 mm – padded postal envelope

MAILmedia Jiffy Size 6 padded mailing bag (300 x 410 mm) is a lightweight postal envelope with internal bubble cushioning designed to protect contents during transit. The envelope combines a tear-resistant outer layer with enclosed air-bubble lining to reduce impact and abrasion on documents, textiles and small items. A self-sealing adhesive strip allows quick closure without additional tape, making the envelope suitable for high-volume dispatch and occasional shipments alike.

Advantages

The padded mailing bag provides reliable cushioning and reduces the risk of damage from shocks and rubbing while remaining lightweight to help control postal costs. The internal bubble padding offers consistent protection across the entire surface of the envelope, and the tear-resistant outer material improves handling durability. The self-seal closure streamlines packing operations and ensures a secure seal. The neutral, plain exterior is compatible with labels, stamps and printing for logistics and tracking.

Suitable for

• Shipping documents, booklets and printed materials
• Sending clothing, textiles and small soft goods
• E-commerce orders and small parcel dispatch
• Returns and customer exchanges

Key specifications

• External dimensions: approximately 300 x 410 mm

• Weight: lightweight design to minimise postage costs

How to use

Insert the item flat into the open end of the padded mailing bag so that fragile areas are aligned with the bubble-lined interior. Remove the protective strip from the adhesive flap and press firmly along the seal to close the envelope. For heavier or bulky items ensure the product fits without overstretching the envelope; if needed, use additional reinforcement such as a cardboard insert to prevent bending. Affix shipping labels or postage information on the outer surface, avoiding covering the seal.

Recommendations

For fragile or valuable contents, combine the padded mailing bag with internal wrapping or supports and select appropriate postal services with tracking and insurance. Store unused envelopes flat in a dry environment to preserve the adhesive strip and material integrity.
