My Buying Guides on Types Of Self Seal Envelope
When I first needed to buy self seal envelopes, I found there were quite a few types to choose from. To help you make the best choice, I’m sharing my experience and what I learned about the different kinds of self seal envelopes available.
1. Peel and Seal Envelopes
These are my go-to envelopes when I want something quick and reliable. They come with a strip covering the adhesive, which you simply peel off and press to seal. I like them because they’re mess-free and secure, perfect for important documents or business mail.
2. Press and Seal Envelopes
This type doesn’t have a peel strip but uses a moist adhesive that seals when pressed. When I’m sending out invitations or greeting cards, these envelopes work well since I don’t have to worry about peeling anything off. However, I do keep a damp sponge handy for moistening the flap.
3. Self Seal Security Envelopes
Security is a big concern for me, especially when mailing sensitive information. These envelopes have a tamper-evident adhesive strip, so if someone tries to open them, it’s obvious. They often come with a patterned interior to prevent reading through the envelope.
4. Clear Window Self Seal Envelopes
When I want to save time addressing envelopes, I choose clear window self seal envelopes. They allow the recipient’s address on the letter inside to show through. I make sure the window aligns well with my document to avoid any misprints.
5. Colored or Printed Self Seal Envelopes
For personal or promotional mail, I like using colored or printed self seal envelopes. They add a nice touch and help my mail stand out. The sealing mechanism is usually peel and seal, combining convenience with style.
What to Consider When Choosing Self Seal Envelopes
- Purpose: Think about what you’re sending—important documents, invitations, or bulk mail.
- Security: If privacy matters, go for security envelopes.
- Ease of Use: Peel and seal envelopes are generally easiest.
- Size and Style: Make sure the envelope fits your contents and suits your brand or personal taste.
- Quantity and Budget: Buying in bulk can save money if you send a lot of mail.
I hope this guide helps you find the perfect self seal envelopes for your needs!
