## Long description

BSTech Bubble Mailer Envelope K20 in size 370 x 480 mm is a padded protective mailing envelope designed for shipping medium-size items. Each pack contains 50 self-sealing envelopes featuring an internal air bubble lining and a tear-resistant exterior. The lightweight construction reduces postage costs while providing cushioning to protect books, documents, electronics and small parts during transit.
Advantages
The BSTech K20 bubble mailer combines a durable outer layer with internal air-bubble cushioning to absorb shocks and resist punctures and tears. Self-sealing adhesive strips speed up packing and provide a secure closure without additional tape. The envelopes are lightweight to help keep shipping costs down while still offering reliable protection for non-fragile to moderately fragile items.
Suitable for
 Mailing books, magazines and printed materials
 Sending small electronics and accessories (chargers, cables, cases)
 Packaging small parts, components and spare parts
 Posting documents and flat items that require light cushioning
When it may not be suitable
These padded envelopes are not intended for heavy or highly fragile items that require rigid protection or specialized shock-absorbing packaging. Bulky or sharp-edged objects may still puncture the bubble lining or deform the envelope, so rigid boxes or additional internal protection should be used in those cases.
Key specifications
 External dimensions: 370 x 480 mm
 Packing quantity: 50 envelopes per pack
 Internal cushioning: air bubble lining
 Closure type: self-sealing adhesive strip
 Exterior: tear-resistant, lightweight material
How to use
Insert the item into the envelope so it lies flat against the bubble lining, fold down the flap and remove the protective strip from the adhesive. Press the flap firmly to close and ensure the seal is tight along the edges. For additional security or for higher-value goods, consider reinforcing the seal with tape or placing the item in an inner protective sleeve before inserting into the mailer.
What to consider before purchase
 Verify that the 370 x 480 mm internal space is sufficient for your item, including any inner packaging.
 Assess the fragility and weight of the item — use a box or additional padding for heavier or very fragile goods.
 Consider postage costs and carrier size limits for padded envelopes of this dimension.
Usage recommendations
Use BSTech Bubble Mailer K20 for documents, books and small electronics that need light-to-moderate protection. For sharp or heavy items, add internal reinforcement or choose a rigid box to avoid punctures and ensure safe delivery.
