18 x 48" Long Poly Mailer

These 18 x 48 inch long poly mailers are constructed from 2.5 mil polyethylene, offering durable moisture resistance and puncture protection for oversized and elongated items that fall outside standard mailer dimensions. The 2.5 mil thickness maintains envelope integrity through sortation and transit without adding meaningful weight to outbound shipments.

The format suits e-commerce operations, warehouse outbound lines, retail distribution, and manufacturing environments shipping items such as rolled fabrics, banners, long flat goods, posters, and textiles. The generous opening eliminates the need to fold or repackage items that would otherwise require custom solutions.

Each case contains 25 mailers. The polyethylene construction provides flexibility alongside its moisture barrier, conforming to irregular shapes without compromising the seal. Ships via parcel carrier for convenient restocking at facilities of any size.
