Bubble Mailer Envelope BSTech B12 140x225 mm, padded protective envelope, pack of 200

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.
