Catalog #1131A, V-flap-glassine envelopes Catalog #1131A, Easy-open-flap Catalog #1131D, Side Opening or 'V' Flap glassine Envelope

Side-opening glassine envelopes are preferred by many collectors because the V-shaped flaps can be opened in the field with one hand. They have seams folded outside to protect contents, and are made of 20 lb. glassine for maximum protection and humidity resistance. They are pH balanced, acid free, lignin free and un-buffered.  Smooth-edged flaps are folded down and are not gummed.  Envelopes are packed in lots of 100.

The 1131D envelope accepts a 3 x 5" file card for entering collection data, or for support in a file card system.

Thanks to Al Thurman in Arizona (also in Panama whenever possible) for suggesting this type of envelope flap.

See also 1130DP polypropylene, end opening, Odonata specimen envelopes that also accept a 3 x 5" file card.

See 1130A for description of end-opening glassine envelopes.
