Kraft Paper Bubble Mailer Envelopes
Protective padded courier envelopes for e-commerce orders, mobile accessories, product samples, documents, books, clothing, office dispatches and everyday courier packaging. Each selected size is supplied as a pack of 10.
What Is a Kraft Paper Bubble Mailer?
A kraft paper bubble mailer envelope is a padded mailing envelope with a kraft paper exterior and a protective bubble-cushioning layer inside. It provides more protection than an ordinary paper envelope while remaining lighter and less bulky than many cardboard boxes.
These padded courier envelopes are useful for online shops, offices, retailers, product suppliers, home businesses and individuals sending suitably sized items through courier and delivery services in Sri Lanka.
Good Packaging Protects More Than the Product
A product can leave your shop in perfect condition but arrive scratched, bent or untidy when the packaging provides too little protection. Customers often judge a seller’s care and professionalism from the condition of the parcel they receive.
Choosing a suitable padded courier envelope is a simple packing decision that may help reduce avoidable complaints, replacement costs and disappointing delivery experiences.

Use the examples below as a practical starting point, then compare the actual packed item’s width, height and thickness with the listed external dimensions.
Choose a Mailer According to What You Are Sending
Sending Important Documents?
Certificates, agreements, photographs, catalogues and presentation documents can be difficult or costly to replace after they become bent or damaged.
Bubble lining provides cushioning, but documents that must remain completely flat should first be placed between suitable backing boards or inside a rigid document folder.
How to Measure Before Ordering
- Measure the widest part of the item or retail box.
- Measure its full height or length.
- Include the product’s thickness.
- Include extra wrapping, invoices, backing boards or supporting materials.
- Select a mailer with enough room to insert and close the item without forcing or bending it.
A Helpful and Honest Sizing Note
The product examples and size suggestions on this page are provided as general educational guidance.

Please compare your fully packed item with the stated external measurements before ordering.
Kraft Paper or Plastic Bubble Mailer?

When a Bubble Mailer Alone May Not Be Enough
- Fragile glass, ceramic or crush-sensitive products may require a rigid box and additional cushioning.
- Sharp objects should be covered securely so they cannot puncture the envelope.
- Liquids should be sealed separately in suitable leak-resistant packaging.
- Documents that must remain completely flat should include rigid backing.
- Heavy products should be packed according to their weight, shape and courier-handling requirements.
