Australia Post Padded Envelopes

Our Kraft Bubble mailers range adheres to Australia Post Postage Guidelines. Available in 7 different sizes, our smaller sizes are best for small electronics and paperwork, whereas the larger sizes can fit small boxed items and binders. Packaging Tape is not required to close these; envelopes come with peel-and-seal strips for easy and secure closure.

The durability of a Shipping Envelope

Kraft Bubble Mailer consists of bubble wrap in the shipping envelope. Although bubble wrap has high impact resistance and antistatic ability, it is not advisable for customers to transport items only in padded bubble wrap. Bubble wrap is non-adhesive and can easily slide around, which means that the items transported with the padded bubble wrap may slip or slide back out of the case, and it can get damaged if packaging is not not properly done. This is where the shipping envelope comes in handy.

Bubble envelopes are all shipping materials made from high-quality kraft paper, a rough, tear-resistant paper made by treating wood chips with sodium sulphide and sodium hydroxide. Kraft paper is solid and flexible and  candy wrappers, food bags, and shotgun shells contain kraft paper. Due to its excellent strength, kraft paper is very suitable as a shipping paper.

These mailers have highly durable interior and exterior cushioning for packages. This makes this type of mailer ideal for shipping flat, sturdy items that require extra padding to survive the journey. Bubble envelopes are ideal for books, CDs and DVDs, jewellery, small electronic devices, and license plates.

If you are looking for a safe and efficient way to transport fragile or delicate items without going broke, then padded mailers are the perfect choice for you. Its slim profile and extremely high durability make ideal for shipping small things which can get damaged during transit. A padded bubble mailer can send flat and fragile items to ensure that the product arrives intact.
