Very sturdy
Style: 10 Inch, Size: 172 Count (Pack of 1)
When we go camping, we use these Dixie plates a lot. They’re very sturdy and the cleanup is easy Peezy. The design is bright and cheerful are easy to use. It’s the great size for dinner plates and they also have smaller size plates as well as bowls. They’re very durable and we’ll hold up on heavy foods. We always keep a good supply on hand because when you’re on vacation, you don’t want to wash the dishes. They are great you’re using them and you throw them away or you can burn them.

Strong, Reliable Plates for Everyday Use
Style: 10 Inch, Size: 100 Count
These Dixie Ultra paper plates are a great upgrade from regular disposable plates. They’re strong and sturdy, so they don’t bend or leak even with heavier or saucy foods. Perfect for everyday meals, cookouts, or quick cleanups when you don’t feel like doing dishes. The 10-inch size is just right for full meals, and the pack lasts a good while. I’ve used them for hot foods without any issues—they hold up really well. Overall, dependable quality and worth paying a little extra compared to cheaper, flimsy options.

Best Plates Ive ever known!
Style: 10 Inch, Size: 172 Count (Pack of 1), Style: 10 Inch, Size: 172 Count (Pack of 1)
If you’re tired of the "double-plate shimmy" where you have to stack two flimsy plates just to survive a barbecue, the Dixie Ultra 10-Inch Plates are a total game-changer. This 172-count bulk pack is the gold standard for anyone who actually likes to pile on the food.
Why They’re Worth It:
True Strength: The "3X Stronger" claim isn't just marketing fluff. These can handle a massive helping of steak, potato salad, and corn on the cob without folding under pressure.
Soak-Proof Shield: They feature a high-quality coating that keeps grease and sauces from leaking through to your lap or your table.
Microwave Safe: Unlike some cheaper alternatives, these don't get soggy or "wilt" when you're reheating leftovers.
Value Size: Getting 172 plates (divided into 4 convenient packs) means you're set for multiple parties, holidays, or just those nights when you really don't want to do the dishes.
Bottom Line: These are the "heavy lifters" of the paper plate world. They’re large enough for a full dinner and tough enough to handle the messiest meals. Highly recommended for anyone who values durability over price-point flimsy alternatives.
