Poly-Lined Water-Resistant Kraft Mailer

The Poly-Lined Water-Resistant Kraft Mailer exists for the shipments that can’t afford a soggy box: apparel headed through a rainy delivery route, liquid or cream-based products with any risk of a leak, or anything traveling to a climate where a plain kraft mailer would show water spotting before it reaches the customer. We laminate a water-resistant poly layer to the interior face of the kraft sheet before converting, so the mailer keeps the warm, printable kraft look on the outside while gaining real moisture resistance where it counts, at the seams and across the body of the mailer.

This is the construction to reach for when a commodity poly mailer feels like the only weatherproof option but you don’t want to give up the branded, premium kraft exterior. Plain poly mailers are watertight but generic — every brand’s looks the same, and the printing is usually limited to a small area. Our poly-lined build gets you the same functional water resistance with full edge-to-edge, full-color printing on a paper surface that photographs far better for unboxing content and feels more substantial in hand.

Apparel and fashion brands use this style heavily for anything shipping folded goods where a wet mailer could stain or dampen fabric, and beauty brands lean on it for orders with any liquid product risk beyond what a padded mailer alone would cushion. It also holds up well in less controlled shipping conditions — porch deliveries, outdoor drop boxes, or long-haul routes with unpredictable weather — where a standard kraft mailer might not.

Seams are fully sealed during production, not just taped, so the water resistance is structural rather than cosmetic. The self-adhesive closure strip completes the seal at the opening. Like our other mailers, minimum order is 250 units with full-color offset printing for larger runs and digital printing for shorter ones. Tell us your product, expected shipping conditions, and target quantity, and we’ll recommend sizing and turn around a mockup within 24 to 48 hours. Standard production ships in two weeks once approved. Get a custom quote for the Poly-Lined Water-Resistant Kraft Mailer today.
