Vacuum Packing Foods into Brick Shape: The Smartest Way to Store Preps
When it comes to prepping and long-term food storage, organization and space-saving aren’t luxuries—they’re necessities. One of the most efficient, professional-looking, and prepper-approved methods of storing dry foods is to vacuum pack them into brick shapes using a chamber vacuum sealer and a box mold.
In this post, we’ll show you how to turn your bulk foods into airtight, stackable bricks that save space, deter pests, and extend shelf life—perfect for bug-out locations, prepper pantries, or off-grid storage bunkers.
🛠 What You’ll Need
-
Chamber Vacuum Sealer – essential for evenly vacuuming without sucking powders or fine debris into the seal.
-
Box Mold – a rigid mold with flat sides to form a compact, rectangular shape.
-
Vacuum Seal Bags – smooth-sided chamber sealer bags (cut to size if needed).
-
Dry Foods – rice, beans, lentils, oats, pasta, flour, dehydrated items, coffee, etc.
🧱 Step-by-Step: Vacuum Packing Foods into Brick Shape
1. Line the Mold with the Bag
Insert your vacuum bag into the box mold, folding the top edges over the sides to keep the bag open. Push the bottom of the bag into the corners for clean lines.
2. Fill the Bag with Dry Food
Pour your chosen dry food (e.g., rice, beans, oats) into the bag while it sits in the mold. Fill about 3/4 full to leave room for sealing.
3. Compress the Food
Gently press the food down using your hand, a pressing board, or a flat surface. This helps form a solid, dense brick.
4. Fold the Top and Transfer to Sealer
Fold the top of the bag neatly and carefully remove it from the mold while maintaining its shape. Place it into the chamber vacuum sealer, making sure the seal end is positioned correctly.
5. Vacuum & Seal
Run your chamber sealer. The air will be drawn out uniformly, forming a tight, professional brick shape. Seal the bag once the form is set. Adjust vacuum time for density as needed.
6. Cool, Label, and Store
Allow your bricks to cool flat. Label each with the food type and date. Stack them upright or flat—either way, you’re saving major shelf space.
🍚 What Foods Work Best?
This method is ideal for:
-
Dry Beans (black, pinto, navy)
-
White or Brown Rice
-
Lentils, Split Peas
-
Rolled Oats & Instant Oats
-
Pasta (elbow, shells, spaghetti)
-
Flour, Cornmeal, and Powdered Milk (use extra care or freeze first)
-
Dehydrated Vegetables
-
Freeze-Dried Meals
-
Coffee or Tea
Avoid fresh, high-moisture items unless they’re frozen.
🔒 Why Vacuum-Sealed Bricks Are a Game-Changer
✅ Saves Storage Space – Neat bricks stack like books on a shelf
✅ Prevents Pests – No oxygen = no bugs
✅ Extends Shelf Life – Less air, less spoilage
✅ Professional Look – Great for barter, sale, or gifting
✅ Tactical & Practical – Load-out ready, easy to organize by type or date
✅ Less Waste – Airtight seals protect from moisture and rodents
📦 Pro Tip: Add Oxygen Absorbers
For foods with long shelf lives, toss in an oxygen absorber before sealing. It’s optional with vacuum sealing, but adds another layer of preservation.
In a world where efficiency matters—and survival might depend on how prepared you are—vacuum sealing your dry foods into brick shapes is a next-level prepper hack. It’s smart, space-saving, and ready for anything.
Stay prepared. Stay organized.
