Expansion Poly Mailers
You'll enjoy the way that the bottom gusset on these poly mailers allows it to expand and conform to items that have depth greater than paper mailings.
We recommend these Expansion Poly Mailers for items such as purses, blankets, bulky apparel, books and any other thick items. These mailers will conform better to these product shapes, making a neater presentation to the recipient.
Like our other poly mailers, these are manufactured from tear-proof polyethylene, are resistant to dirt, dust and moisture, and their high quality seals allow for over-stuffing.
The self-sealing adhesive strip will instantly secure the mailers closed, making them tamper-evident, inspiring greater confidence upon receipt that the package contains exactly what you shipped.
See our Poly Mailer Shipping Guide for more information.
