Bubble Mailer Envelopes NC Koperty D/14, size D/14, pack of 10

NC Koperty bubble mailer envelopes model D/14, pack of 10, are padded postal envelopes designed to protect small to medium items during shipping and storage. Each envelope features internal bubble cushioning that reduces impact and abrasion for documents, small electronics, accessories and other items that need lightweight protection. Envelopes are intended for postal and courier use and come in a convenient pack of ten for routine packing tasks.

Advantages

These NC Koperty bubble mailers provide integrated air-cushion padding that helps absorb shocks while keeping the overall package lightweight to avoid excessive postage cost. The self-seal adhesive strip ensures simple and quick closure without additional tape. Their compact, flexible construction conforms to irregularly shaped items and reduces movement inside the mailer, while the smooth outer surface is suitable for printing address labels or applying shipping stickers.

Suitable for

• Small electronics such as phones, chargers and cables
• Documents, certificates and thin booklets
• Jewellery, small accessories and cosmetics
• Fragile but compact items requiring lightweight cushioning

Key specifications

• Padded bubble interior for impact protection
• Outer material: mailer-grade flexible film
• Self-seal adhesive closure strip
• Pack quantity: 10 envelopes
• Size designation: D/14 (for small to medium items)
• Lightweight construction to help minimise postage costs

How to use

Insert the item so it lies flat against the bubble interior and remove any excess air from the envelope before sealing. Peel off the protective strip on the adhesive closure and press firmly along the flap to ensure a secure seal. For added security, apply a shipping label or mark the outside with recipient details; fragile items can be wrapped in an extra protective layer before placing them in the mailer.

Usage recommendations

Choose an appropriately sized D/14 mailer so the item fits without excessive folding or strain on the closure. For very fragile or high-value goods, combine the mailer with additional internal padding or place the mailer inside a rigid outer box. Store unused mailers flat in a cool, dry place away from direct sunlight to preserve the adhesive strip and outer film.
