Padded Mailing Bag MAILmedia Jiffy Size 3 — 200 x 290 mm, protective bubble-lined envelope

MAILmedia Jiffy Size 3 padded mailing bag measures 200 x 290 mm and features an internal bubble lining that cushions small to medium flat items during transit. The envelope is designed for lightweight protection of documents, thin electronic devices and small accessories while keeping overall parcel weight low. A self-seal adhesive strip secures the closure and simplifies packing for single-item shipments or multiple-item assortments laid flat.

Advantages

The bubble-lined interior absorbs shocks and helps prevent scratches and minor impacts without adding significant bulk. Its compact 200 x 290 mm dimensions are suitable for standard documents and many small electronics, while the lightweight construction reduces postage costs compared with rigid packaging. The self-seal closure provides quick, reliable sealing and eliminates the need for additional tape.

Suitable for

• Flat documents and booklets
• Small electronics such as phones, power banks and chargers (flat items)
• CDs, DVDs and media discs in sleeves
• Jewellery, small accessories and soft items
• Printed materials, photographs and thin catalogues

Key specifications

• External dimensions: 200 x 290 mm
• Internal protective bubble lining for cushioning
• Self-seal adhesive closure for fast packing
• Lightweight polyethylene outer film
• Slim profile suitable for flat items and low-volume shipments

How to use

Insert the item flat into the bag so it rests against the bubble-lined interior, ensuring the most vulnerable face is protected. Remove the protective strip from the adhesive closure, fold the flap down and press firmly along the seal to secure the envelope. For added protection of fragile corners, wrap the item in a thin protective sleeve before placing it inside. Confirm the sealed flap is fully adhered before labelling or shipping.

Recommendations

Use this padded mailing bag for single flat items or small grouped flat items; do not rely on it alone for heavy or highly fragile goods. For very fragile electronics or items with sharp edges, add additional corner protection or choose a rigid box to prevent punctures. Check carrier size and weight limits and label the parcel clearly before dispatch.
