Why Mylar Bags for Food Storage?

Unmatched Preservation

Shelf Life with Mylar + Oxygen Absorbers:

White rice: 20-30 years
Dried beans: 20-30 years
Wheat berries: 20-30 years
Pasta: 20-30 years
Oats: 20-30 years
Flour: 10-15 years
Dehydrated foods: 15-25 years
Freeze-dried: 25-30 years
Sugar/salt: Indefinitely

Without Oxygen Absorbers: 1-5 years

Superior to Alternatives

Better Than:

Regular plastic bags (permeable)
Vacuum seal only (still has oxygen)
Buckets alone (not airtight)
#10 cans (expensive, not resealable)

How Mylar Preserves Food

Barrier Protection

Aluminum Layer Blocks:

100% of light (prevents degradation)
Oxygen transfer (stops oxidation)
Moisture (prevents spoilage)
Pests (sealed barrier)

Result: Food remains nutritionally viable for decades.

Oxygen Absorber Role

What They Do:

Remove oxygen from sealed bag
Reduce O2 to 0.01% or less
Prevent oxidation
Stop bacterial growth
Eliminate insect eggs
Extend shelf life dramatically

Sizing:

1 quart bag: 100cc absorber
1 gallon bag: 300cc absorber
5 gallon bag: 1500-2000cc

Step-by-Step Food Storage

Complete Process

1. Select Foods

Low moisture (under 10%)
Dried grains, beans, pasta
Freeze-dried items
Dehydrated foods

Foods to AVOID:

High moisture content
Oils/fats (go rancid)
Nuts (oils present)
Brown rice (oils)
Fresh foods

2. Prepare Mylar Bags

Choose appropriate size
Inspect for defects
Label bags beforehand (easier)

3. Fill Bags

Pour food to 2/3 full
Leave 3-4" at top
Avoid overfilling
Keep seal area clean

4. Add Oxygen Absorber

Match size to bag volume
Drop in quickly
Work fast (absorbers activate)
One per bag

5. Remove Excess Air

Gently squeeze out
Don't need vacuum (absorber removes O2)
Some air okay

6. Heat Seal

Use heat sealer
3-5 seconds
Complete, strong seal
Test integrity

7. Label Clearly

Contents
Date sealed
Weight/quantity
Expiration (if known)

8. Store Properly

Cool (50-70°F)
Dark location
Dry area
Off ground
Organized system
