12 x 15 1/2 Mailers

Flexible 12 x 15 1/2 inch shipping bags provide useful space for apparel, textiles, documents, accessories, and everyday customer orders. JAM Paper poly mailers offer moisture-resistant coverage for non-fragile goods while remaining easy to store and handle at packing stations. The versatile dimensions fit a wide range of retail and commercial shipping tasks.

Black, white, blue, and citrus options add variety to routine packaging while allowing businesses to coordinate outgoing orders by color or presentation. Peel & seal closures help speed up fulfillment without requiring separate adhesive, and the flexible exterior conforms naturally around soft merchandise. These mailing envelopes suit online stores, offices, warehouses, and promotional shipments.

Apparel and fabric-based products often need coverage rather than rigid cushioning. Poly mailers provide an efficient solution for garments, textiles, catalogs, promotional pieces, and other non-breakable contents that can travel in flexible packaging. Their generous size balances practical capacity with a manageable footprint for recurring order preparation.
