One of the most practical tools in stamp collecting is the glassine envelope. This handy item is a popular seller and has many uses, especially for storage. We at Arpin Philately cannot sing its praises loudly enough. Glassine envelopes are what we use to store all of our bulk stock. What makes them so ideal?
Firstly, they are made of high quality #30 semi-transparent acid free glassine. You can easily store hundreds of stamps per envelope, depending on their size and the size of the envelope. We have 11 different sizes of envelopes for you to choose from, in packs of 100 or boxes of 1000. Glassine is a paper product which is grease, air, and water resistant, so you can also label your envelopes with a marker and not worry about leakage through the paper. For water resistance, make sure your envelope is well sealed shut.
The fact that glassine envelopes are acid free is an important point. Some papers and cardboards contain chemicals which, if they come into contact with your stamps, could actually damage them. No such worries with glassine envelopes. You can use them to store your stamps for a long period if necessary.
Glassine envelopes are useful for other hobbies or occupations also, such as photography. The acid-free glassine is perfect for storing film and prints. Other markets where glassines have become popular are marketing, food packaging and fashion, either in envelope or sheet form.
