The QUALITY PARK QUA42354 is an extra-large open-end envelope built for storing and transporting oversized flat materials. Measuring 14 inches by 18 inches and constructed from 28 lb Kraft stock in natural brown, these envelopes provide a sturdy, professional-grade solution for documents that cannot be folded. The ungummed flap design allows repeated access without adhesive interference, making them a practical choice for job sites, print shops, and professional offices where flat materials move frequently between hands. Each box contains 25 envelopes.
These envelopes are commonly used by architects, engineers, print professionals, and contractors who need to protect blueprints, construction drawings, proofs, artwork, and other large-format flat documents. The 14-inch by 18-inch interior provides ample clearance for standard architectural and engineering sheet sizes. The open-end configuration allows materials to slide in and out without bending or creasing. Ungummed flaps make them well suited for temporary storage as well as repeated retrieval during active projects.
Designed as a standard open-end Kraft envelope suitable for storing and mailing large-format flat documents including blueprints, architectural drawings, artwork, and proofs up to 14 x 18 inches.
No tools or installation required. When loading documents, ensure materials are fully dry and free of debris before inserting to avoid damage to contents. For secure transit, fold and seal the ungummed flap with tape or a binder clip as needed. Store boxes flat in a dry environment to maintain envelope integrity.
