Why Choose Starburst Yellow Booklet Envelopes?

  • High-visibility color: Bright yellow helps mailings, routed documents, and departmental packets stand out.
  • Wide booklet opening: The opening runs along the longer side for easier insertion of large and multi-page materials.
  • Documents remain flat: The 9″ x 12″ size accommodates many reports, brochures, photographs, and handouts without folding.
  • Substantial paper weight: Durable 28 lb. paper provides a heavier feel than lightweight mailing envelopes.
  • Dependable construction: Two side seams under support everyday mailing and document-handling applications.
  • Traditional closure: The remoistening adhesive seals after it is moistened and the flap is pressed closed.
  • Useful for organization: Yellow supports color-coded routing by department, project, document type, or priority.
  • Efficient bulk packaging: All 500 envelopes are packed together without individual inner boxes.

Choosing the Correct 9″ x 12″ Envelope

Booklet Envelopes vs. Catalog Envelopes

Booklet envelopes open along the longer dimension, creating a wide opening for reports, booklets, and presentation packets. Catalog envelopes open along the shorter dimension and are loaded lengthwise.

Remoistening Seal vs. Self-Seal

These envelopes have a traditional remoistening seal. The adhesive must be moistened before the flap is closed. They do not have a peel-away liner or pressure-sensitive self-seal closure.

Bulk Carton vs. Individually Boxed Envelopes

Item 7421 is bulk packed. All 500 envelopes are placed directly in the shipping carton without separate inner boxes. This format is well suited for centralized supply rooms and high-volume use.
