Bolsa de envío MAILmedia Jiffy talla 7 350 x 450 mm — funda postal acolchada

MAILmedia Jiffy Size 7 is a padded mailer envelope measuring 350 x 450 mm designed for secure shipping of documents, clothing and medium-sized items. The envelope combines a cushioned inner bubble layer with a durable kraft outer surface and a self-adhesive closure that ensures simple, reliable sealing during packing and dispatch.

Advantages

The padded mailer provides impact protection and abrasion resistance while remaining lightweight to help reduce postage costs. Its kraft outer surface resists tearing and moisture to a practical degree for standard postal and courier handling. The peel-and-seal adhesive strip offers quick closure without additional tape, and the internal bubble lining cushions contents against shocks during transit.

Suitable for

• Shipping documents, magazines and printed materials
• Mailing folded clothing, textiles and soft goods
• Sending medium-sized retail items such as accessories and small electronics
• Returns, e-commerce orders and postal dispatches

Key specifications

• External dimensions: approximately 350 x 450 mm
• Construction: kraft outer layer with internal bubble cushioning
• Closure type: self-adhesive (peel-and-seal) strip
• Weight: lightweight design to minimise shipping cost
• Protection: cushioning against impacts and scuffs during transit

How to use

Insert the item so it lies flat and centered within the padded interior. Remove the protective strip from the adhesive closure, fold the flap down and press firmly along the seam to secure the seal. For irregular or heavy items, consider reinforcing corners or edges with additional internal wrapping to prevent punctures. Clearly label the outside with the destination address and any required postage or customs documentation.

Recommendations

Use the MAILmedia Jiffy Size 7 padded mailer for items that require basic impact cushioning combined with a lightweight, tamper-evident closure. Avoid overstuffing beyond the envelope dimensions and add extra internal protection for fragile objects. Store unused mailers in a dry place away from direct sunlight to preserve adhesive performance and material integrity.
