Frequently Asked Questions
Do Tyvek mailers reduce postage compared with standard paper envelopes?
Yes — Tyvek is much lighter than equivalent heavy paper envelopes, so for flat or bulky soft shipments it typically lowers postage by weight. Tyvek also resists tearing and moisture, but it provides no internal cushioning so add protection if shipping fragile items.
Are poly bubble mailers waterproof?
Most poly bubble mailers have a waterproof outer film that resists rain and moisture during transit. The interior bubble lining protects against impact, but seams and seals should be inspected or reinforced for high-risk shipments.
How do I pick the right size to avoid extra postage?
Choose the smallest mailer that fits items with minimal folding or extras; check the usable interior dimensions listed (not just outer dimensions). Avoid overly large mailers with extra air volume, since some carriers use dimensional weight for pricing on larger packages.
