How to Choose the Best Filing Envelopes
Material Matters
- Paper: A common and affordable choice, paper envelopes are suitable for everyday filing and temporary storage. Look for thicker cardstock for added durability.
- Plastic/Polypropylene: These offer superior protection against moisture, tears, and spills. They are ideal for frequently accessed documents or items that need extra safeguarding.
- Tyvek: Known for its exceptional strength and tear resistance, Tyvek envelopes are a premium option for long-term storage or high-value documents.
Size and Capacity
- Standard Letter/Legal: The most common sizes, designed to fit standard 8.5" x 11" or 8.5" x 14" documents without folding.
- Expansion: For thicker files, choose envelopes with expanding gussets. These can hold a significant number of pages, reducing the need for multiple envelopes.
- Specialty Sizes: Consider smaller envelopes for receipts or index cards, or larger ones for blueprints or artwork.
Closure Types
- Flap and Gum/Moisten-to-Seal: A traditional closure, best for less frequently accessed items as the adhesive can degrade over time.
- Button and String/Braid: A secure and durable closure, ideal for documents that are handled often or need to be kept firmly enclosed.
- Interlocking/Tab Closure: Offers a simple, secure closure without the need for adhesive or ties, often found on plastic envelopes.
