## Summary description

## Long description

BSTech B12 bubble mailer envelopes (140x225 mm) are padded protective envelopes designed for secure shipment of small, lightweight items. Each envelope features an internal layer of air-filled bubbles that cushions contents against shocks and impacts, while the tear-resistant outer layer helps prevent punctures and abrasions during handling and transit. This pack contains 200 envelopes sized for documents, small electronics, accessories and other items commonly sent by mail or courier.
Advantages
The internal bubble cushioning provides consistent shock absorption across the envelope surface, reducing the risk of damage to fragile or sensitive items. The lightweight construction keeps postage costs low compared to rigid packaging, and the padded envelope format simplifies packing by combining protection and an outer mailing surface in one product. A self-sealing closure speeds up fulfillment and reduces the need for additional tape or adhesives.
Suitable for
Small documents, folded papers and cards
Mobile accessories such as chargers, cables and earbuds
Compact electronics and replacement parts
Jewellery, small cosmetics and other fragile but compact items
E‑commerce order fulfillment and postal shipments
When it may not be suitable
These bubble mailers are intended for small, lightweight items; they are not suitable for heavy, bulky products or items with sharp edges that could puncture the inner bubble lining. For high-value, extremely fragile goods or items requiring rigid support, consider boxed packaging with internal foam or molded inserts.
Key specifications
External dimensions: approximately 140 x 225 mm
Padding type: internal air bubble cushioning
Outer material: tear-resistant protective film
Closure: self-seal adhesive strip
Pack quantity: 200 envelopes
Primary use: mail and courier parcel protection for small items
How to use
Insert the item into the envelope so that it lies flat and is centered within the bubble layer. Remove the protective strip from the adhesive closure and press firmly along the sealing flap to create a secure bond. For additional protection of sharp or irregularly shaped items, wrap the item in an extra layer of protective film before placing it in the mailer. Label the outer surface with the recipient address and any required postage or shipping labels.
What to consider before purchase
Confirm the internal usable space relative to your item dimensions to ensure a proper fit.
Assess whether the bubble padding and envelope strength meet the protection needs for your specific product.
Consider postage weight limits and cost savings from lightweight padded mailers versus boxed shipments.
Usage recommendations
Use the BSTech B12 140x225 mm bubble mailers for routine shipments of small electronics, accessories and documents. For better protection of sharp or fragile pieces, combine the mailer with a light inner wrap and avoid overstuffing to maintain the integrity of the bubble layer.
