Heavy-duty polypropylene envelopes

These envelopes are made from heavy-duty polypropylene that resists tears and repels moisture. They come in a translucent red colour that helps with quick visual organisation. The pack contains five booklet-style envelopes suited for storing or transporting documents. Acid-free and PVC-free materials make them safe for archival-quality storage.

String-tie closure and gusset

A heavy-duty string and button closure secures the contents for everyday handling. The gusset expands up to 1 1/4 inches to hold bulkier materials without stressing the seams. Side-load orientation allows easy insertion and removal of pages. No power draw, noise or thermal output is involved with this passive storage product.

Acid-free archival construction

The envelopes are acid-free, PVC-free and rated archival-quality for long-term document preservation. Polypropylene construction withstands repeated opening and closing without cracking. Horizontal orientation and side-loading design suit desk filing or bag carry. Buyers who need a different colour code or a larger quantity per pack will need another product.

Questions about this item

How do you secure the string-tie closure on these envelopes?

Thread the string through the button, wrap it around twice, and pull tight so the button sits flush against the gusset; the step people miss is the second wrap, which keeps the tie from loosening during handling.

Will the string or button need replacing with daily use?

The heavy-duty string and button are built for everyday use and typically last the life of the envelope; if the string frays or the button cracks, you can swap in a similar-length cord and a standard flat button.

At what point does the 1 1/4" gusset expansion limit capacity?

The gusset stops expanding at 1 1/4", so once contents reach that thickness the envelope will not close flat and the string-tie cannot fasten securely.
