Buyer's guide
Last updated: July 2026 · By TWO Packaging
Uline is a giant, reliable source of stock shipping and industrial supplies — boxes, tape, mailers, off the shelf and fast. TWO Packaging is a custom manufacturer that prints packaging to your brand and makes regulated formats Uline doesn't. If you need branded, custom, or child-resistant packaging, they're not really the same category.
For plain, unbranded shipping supplies you need in bulk and fast — corrugated boxes, poly mailers, tape, dunnage — Uline is hard to beat on selection and speed. If you just need stock materials to ship orders, use Uline.
Uline is stock; TWO is custom. When you want packaging that carries your brand — custom-printed mylar bags, jars, pop tops, tincture bottles, and printed retail cartons — and especially anything child-resistant and compliant, TWO is the manufacturer for it. US-made, ASTM F2117 / ISO 8317 certified, all-in pricing, in-house design, minimums from 1,000 units, free samples.
Why TWO is different: TWO Packaging was built by people who came from the operator side — they ran brands and placed these exact orders themselves. They've felt the sting of hidden fees, blown deadlines, and suppliers who don't answer the phone, and they built TWO to be the partner they wished they'd had. That's why the pricing is fair, the answers are honest, and the service anticipates what a growing brand actually needs.
