Fit / not the right fit
Packrift is a good fit for shipping flat, soft, or non-fragile items where DIM weight matters and you want stock mailers by size and mil.
Packrift is not the right fit for fragile items over 5 lb (use a corrugated box), custom-printed branded mailers, or buyers who need 24/7 phone support.
FAQ
What does a #2 bubble mailer fit?
#2 (8.5x12 inches) fits a paperback book, a mid-size apparel folded item, or a small accessory bundle. See the bubble mailer size code chart for the full code-to-dimension mapping.
Should I use a poly mailer or a bubble mailer?
Poly mailer for soft, non-fragile items (apparel, textiles, paper goods). Bubble mailer when the item benefits from light cushioning (paperbacks, small electronics, jewelry boxes). Use a corrugated box for anything fragile or over 5 lb.
Can I order one mailer, or a full bundle?
Packrift sells in the bundle quantity shown on each product page (commonly 100, 250, 500). There is no further minimum.
Where does Packrift ship from?
Five US warehouse regions: Central Illinois, Northeast Pennsylvania, South Texas, Southeast Georgia, and West California. Each order routes to the closest warehouse with stock.
