Bubble Mailer Envelope BSTech F16 240x350 mm 100 pcs – padded protective mailing envelope

BSTech Bubble Mailer F16 (240x350 mm), pack of 100, are padded mailing envelopes with internal bubble cushioning designed to protect items during postal and courier transport. The envelopes combine a lightweight outer layer with an internal air-filled bubble lining to provide impact absorption and scratch resistance for documents, books and small electronics. The size suits standard documents and media while keeping mailing weight low.

Advantages

The padded construction reduces the risk of damage from drops, knocks and abrasion while the peel-and-seal closure speeds up packing and secures contents without additional tape. A durable outer surface resists tearing and moisture to a practical degree for normal shipping conditions. The standardized rectangular format simplifies sorting and fits typical postal and courier processes.

Suitable for

• Shipping documents, letters and contracts that need extra protection
• Mailing books, booklets and printed media
• Sending small electronics and accessories such as phones, chargers and cables
• Small retail shipments and returns where cushioning and lightweight packaging are important

When it may not be suitable

These bubble mailers are not designed for very heavy or sharp-edged items that can puncture the inner bubble layer or require rigid protection. For fragile items that need rigid immobilization or climate-sensitive goods, a different packaging solution such as a boxed pack with foam inserts or temperature-controlled packaging should be used.

Key specifications

• External size: approximately 240 x 350 mm
• Internal padded bubble lining for impact cushioning
• Peel-and-seal adhesive closure for quick sealing
• Pack quantity: 100 envelopes
• Lightweight construction suitable for lowering postage costs

How to use

Place the item inside the envelope ensuring it lies flat and is centered over the bubble lining. Remove the protective strip from the adhesive flap and fold the flap down to seal firmly. For heavier contents, consider reinforcing the seal with additional tape. Label or affix the address and postage on the outer surface, avoiding folding or creasing the sealed flap.

What to consider before purchase

• Ensure the 240 x 350 mm size fits your item with some margin for padding
• Consider item weight and edge sharpness; use alternative packaging if item could puncture the bubble layer
• Check postal and courier size and weight limits to optimise postage costs

Usage recommendations

For best protection, combine the BSTech Bubble Mailer F16 with internal wrapping such as paper or thin foam around very delicate items, and always centre the item to maximise cushioning. Store unopened packs flat in a dry place away from heat to preserve adhesive performance.
