Sparco Size 7 Bubble Cushioned Mailers

These mailers are #7 sized envelopes made from durable Kraft paper with interior bubble cushioning. They are designed for shipping items that require protective padding during transit. The self-seal closure allows quick sealing without water or glue. A carton contains 50 mailers for bulk shipping needs.

Suits shippers needing lightweight protective

The self-seal closure speeds up packing for high-volume dispatch. The Kraft construction keeps parcel weight low to help manage shipping costs. Buyers who need waterproof or rigid mailers should look at alternative packaging types. Those requiring recycled content mailers will not find that feature here.

Holds items within 14.25 by 20 inch dimensions

The bubble lining protects contents such as documents, electronics accessories or small goods from impact. The envelope runs out of space for thicker objects or anything exceeding the stated length and width. Heavy or sharp-edged items may need a box instead of a padded envelope.

Questions about this item

What size items fit inside the 14.25" by 20" mailer?

The interior dimensions match the #7 classification at 14.25 inches wide by 20 inches long, so flat items up to that size will fit with the bubble cushioning.

Can I use these mailers with a standard postage scale and label printer?

Yes, the lightweight Kraft construction and self-seal closure work with any scale or label printer you already use for regular envelopes.

How do I confirm the self-seal closure is holding after I pack an order?

Press the flap firmly; the adhesive bonds on contact without water or glue, and the seal stays closed unless deliberately torn open.
