Bubble Mailers NC Koperty K/20 — 10 pcs (75060), padded mailing envelopes, protective bubble lining

NC Koperty K/20 bubble mailers (pack of 10, model 75060) are padded mailing envelopes designed to protect small items during postal transport. Each envelope includes an internal bubble lining that cushions contents against shocks and abrasion while keeping overall weight low. These mailers are suitable for sending documents, compact electronics, accessories and other lightweight, fragile goods that require basic impact protection and moisture resistance during handling and transit.

Advantages

The internal bubble lining provides uniform cushioning across the entire envelope, reducing the risk of damage to contents from drops or pressure. Lightweight construction helps to minimise postage costs compared with rigid packaging while maintaining protective performance. Self-sealing closure simplifies preparing shipments and ensures consistent sealing without additional tape. The envelopes are sized for small items and slim parcels, offering easy insertion and reliable protection in postal sorting systems.

Suitable for

• Mailing documents and small printed materials
• Shipping small electronics such as phones, chargers and accessories
• Sending jewellery, cosmetics and other small fragile items
• Dispatching samples, replacement parts and lightweight components

Key specifications

• Pack quantity: 10 padded mailers
• Interior: bubble cushioning lining for impact protection
• Closure: self-sealing strip for fast sealing
• Construction: lightweight, flexible exterior for easy handling
• Intended use: postal and courier shipments of small, fragile or lightweight items

How to use

Insert the item into the padded mailer ensuring it lies flat and is centred on the bubble lining. Remove the protective strip to expose the adhesive and press firmly along the full length of the seal to close. For extra security with valuable or sharp-edged items, consider adding internal wrapping or reinforcement before sealing. Affix the shipping label or address information on the exterior surface, avoiding covering the seal area.

Usage recommendations

Choose these bubble mailers when you need light impact protection with low postage weight; for high-value or heavy items, select a more rigid or reinforced packaging solution. Store unused envelopes in a dry, cool place away from direct sunlight to preserve adhesive performance and bubble integrity.
