Each mailer is constructed from 0.028-inch white chipboard, providing rigid, crush-resistant protection. The side-loading design speeds up the insertion process compared to top-loading alternatives. A peel-and-seal closure secures contents during transit, and a pull-tab strip allows recipients to open the mailer cleanly. This product is sold in a pack of 200 units, making it well suited for high-volume shipping operations.\u003c\/p\u003e\n\u003cp\u003eThese mailers are used in mailroom, fulfillment, and shipping environments where flat documents, photos, artwork, blueprints, or similar materials require rigid protection. The 12.25-inch by 9.75-inch interior opening accommodates standard large-format documents and presentation materials. The rigid chipboard construction eliminates the need to insert separate backer boards, reducing pack time on the line. Facilities processing large daily volumes of outgoing flat mail will find the 200-count pack a practical replenishment unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSide-loading opening speeds document insertion in high-volume fulfillment settings\u003c\/li\u003e\n  \u003cli\u003e0.028-inch white chipboard construction provides rigid, stiffener-free protection\u003c\/li\u003e\n  \u003cli\u003ePeel-and-seal closure secures contents without tape or additional materials\u003c\/li\u003e\n  \u003cli\u003ePull-tab strip allows clean, easy opening on the receiving end\u003c\/li\u003e\n  \u003cli\u003eWhite exterior surface accepts labels, stamps, and direct printing\u003c\/li\u003e\n  \u003cli\u003eSold in a 200-count pack for efficient replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard side-loading flat mailer suitable for documents, photos, and flat printed materials measuring up to 12.25 inches wide by 9.75 inches in length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eNo tools are required for use.
