These Bubble Lined Envelopes (Size 9, 300x445mm) are ideal for small business owners and frequent shippers who require a balance of impact protection and lightweight construction for fragile goods. Offering superior cushioning thanks to their internal bubble lining and a secure peel-and-seal closure, they ensure items arrive intact during transit. The primary caveat is that these envelopes are not waterproof, meaning they should be stored in a dry environment to maintain the integrity of the paper exterior.

Because they consist of a paper exterior and a plastic bubble interior, you should check with your local recycling facility as they may require the layers to be separated.
Yes, they are suitable for international shipping, but ensure the weight of the items complies with your courier's shipping classes.
These envelopes are lightweight, designed specifically to minimize additional postal costs while providing protection.
Yes, the 75gsm paper exterior is opaque enough to conceal the contents of the package.
Most standard desktop printers are not equipped to handle the thickness of a bubble mailer; it is recommended to use adhesive shipping labels instead.
Ensure the surface is clean and free of dust before peeling; if the strip is old, use a piece of clear shipping tape to reinforce the flap.
Wrap the sharp-edged item in a layer of cardboard or additional bubble wrap before placing it inside the envelope to prevent damage from within.
To ensure the best results, always ensure that your item does not exceed the envelope dimensions, as overstuffing may weaken the structural integrity of the sides. Store these envelopes in a cool, dry place away from direct sunlight to keep the adhesive strip from degrading. While they are designed for mailing, they are not intended for use in high-moisture environments. When preparing for shipment, verify that the delivery address is clearly marked on the white paper exterior using a permanent marker or an adhesive label, as standard ballpoint pens may snag on the paper surface.
