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.

Frequently Asked Questions

What is the difference between a filing envelope and a file folder?
A file folder is typically made of thinner cardstock and opens on one side, designed to hold documents within a larger filing system. A filing envelope is usually more robust, often with a sealed side and a closure, providing better protection and containment for individual document sets.
Are plastic envelopes better than paper ones?
Plastic envelopes offer superior protection against moisture, tearing, and general wear and tear compared to paper. However, paper envelopes can be more eco-friendly and are suitable for less sensitive documents or short-term storage.
How do I choose the right size envelope?
Consider the size of the documents you need to store. Standard letter or legal sizes are most common. If you have many pages or documents that shouldn't be folded, look for expanding envelopes with gussets to accommodate thicker stacks.
What does 'expanding gussets' mean?
Expanding gussets are pleats or folds on the sides of an envelope that allow it to expand and hold a greater thickness of paper. This is useful for bulky files that would otherwise not fit into a standard flat envelope.
Can filing envelopes be reused?
Yes, many filing envelopes, especially those made from durable materials like plastic or Tyvek, can be reused multiple times. Ensure they are kept clean and the closure mechanism remains functional for continued use.
