Description:
1. These envelopes add a splash of color to the mail, standing out from the rest and being very different from standard mailers. Your customers will look forward to that attractive white envelope in the mail. Those padded mailers are lightweight mailing envelopes that won't add to your shipping costs.
2. Tear-resistant envelopes. These padded envelopes have a durable and sturdy surface that can replace paper versions, which can be torn by sharp, heavy or oddly shaped products. In addition, multiple layers of polyethylene sheets are used to provide good protection for shipping.
3. Multi-purpose bubble mailer. You can use them to mail cosmetics, paintings, fashion accessories, jewelry, medicines, seeds and light bulbs, and much more. They have enough padding to protect delicate things during shipping. The laminated top allows you to easily attach self-adhesive stamps and address labels.
4. Self-adhesive envelopes. White polyethylene bubble mailers come with self-adhesive tamper-evident seals. Once the envelope is sealed, it cannot be opened without obvious signs of tampering. The smooth surface of the envelope makes it easy to affix stamps and address labels.
