Poly Mailer 10x13 Inch 25 Pcs

Strong & Durable Construction - These mailing envelopes are crafted from new polyethylene material, with a thickness of 2.4 mil on a single side. The edges are designed with reinforced sealing, making them resistant to tears, and bursting. Furthermore, these mailing bags exhibit exceptional waterproof, ensuring the safe delivery of your goods even in foggy or rainy conditions. Easily Peel & Seal - Our sealable polymailers are incredibly quick and easy to seal. Simply peel back the aluminum strip to expose the adhesive and fold to seal. In addition, our adhesive glue is permanent and once sealed, mailer bags cannot be opened again at the closure, ensuring the security of the package. Optimal Privacy Protection - Our thickened mailer bags come with a grey interior lining that provides extra privacy protection, preventing others from peeking into your packages. This is especially important for businesses dealing with confidential products.
