Bubble wrap is also used to line bubble envelopes as well as making air bubble packing bags. These bags offer an ideal solution for packaging and mailing several items, including documents, jewellery, clothing, books, etc. These bags come in a range of sizes. Air bubble packing bags are perfect for packaging small items, whether electrical or fragile. They are made of bubble wrap that provides the best protection against bumps and knocks while they are stored or transported. With these bags, the inside is smooth, so products slide in and out easily.
