Wallaby 5-Gallon Mylar Bags, 15 Count (Zipper, with 2500cc Absorbers)
$55.99
The bucket-liner size: 20x30 bags that drop straight into a 5-gallon pail, with a resealable zipper and 2500cc absorbers included. Best cost-per-volume for staples like rice, beans and wheat.
Pros
- 5-gallon size lines a standard bucket for bulk staples
- Resealable zipper plus heat seal for repeated access
- Includes 2500cc oxygen absorbers matched to the volume
- 10 mil total thickness for a durable, high barrier
Cons
- Higher upfront cost than smaller bags
- Needs a wide heat sealer or an iron to seal the long mouth
The exact product
These are Wallaby 5-gallon mylar bags, about 20 by 30 inches, sold 15 to a pack at 10-mil total thickness with a resealable zipper, and bundled with 2500cc oxygen absorbers matched to the volume. The 5-gallon size drops straight into a standard bucket as a liner.
Best for
- Bulk staples such as rice, beans and wheat stored in 5-gallon buckets
- Best cost-per-volume long-term storage
- People who want a zipper for repeated access on top of the heat seal
Not for
- Small portions, where a quart or gallon bag wastes less
- Anyone without a wide heat sealer or an iron to seal the long mouth
- Moist or oily foods, which defeat the barrier
What we can and can't verify
We separate what the maker claims from what independent sources confirm, what owners report, and where we are drawing an inference. We do not bench-test products.
The manufacturer states
- 10 mil total thickness with a resealable zipper
- Includes 2500cc absorbers matched to the volume
- 5 gallon, roughly 20 by 30 inches, 15 count
Independently verifiable
- The bag lines a standard 5-gallon bucket
- 10-mil mylar is a strong oxygen, moisture and light barrier
- It needs a wide seal, so use a long heat sealer or an iron
Owners consistently report
- Owners praise quality and value; a few report a faint chemical smell on some runs
Our reading of the evidence
- The zipper plus heat seal is the useful combination here: seal for the long term, then use the zipper for working access
What it costs to own
Higher upfront cost than smaller bags, but the best price per gallon of storage. A bag of grain sealed once with the included 2500cc absorber stores for decades, so cost per year is negligible. Put the filled bag inside a bucket for rodent protection.
How it fails, and what to watch
- A weak heat seal along the long mouth lets oxygen in, so seal slowly and firmly
- Rodents chewing bags not inside a bucket
- An undersized absorber for the fill, though the included 2500cc is matched to 5 gallons
- Storing moist food, which defeats the barrier
Limits of this review
We do not lab-test barrier performance or seal strength. Storage-duration figures are quality windows, not safety guarantees; for what is safe to eat, follow USDA and the National Center for Home Food Preservation.
Common questions
Do these fit a 5-gallon bucket?
Yes, they are sized to line a standard 5-gallon pail. Fill the bag inside the bucket, add the absorber, then heat-seal the top.
Do I need the bucket too?
For rodent protection, yes. Mylar is not chew-proof, so keep filled bags inside a food-grade bucket.
How do I seal the long mouth?
Use a long impulse sealer or a household iron along a clean, food-free line; press firmly and evenly the full width.

Alternatives

The everyday long-term standard: 10-mil total thickness, heat-sealable, and bundled with 400cc oxygen absorbers so a bag holds its seal for decades. The size most home storage projects actually use.

A genuine-mylar alternative to Wallaby at a strong price per bag: 50 one-gallon bags with 300cc oxygen absorbers included, from a long-standing brand trusted in the storage community.

The single-meal size: 50 quart bags with write-on labels, ideal for portioning dehydrated meals, seeds and spices. 5-mil is plenty for smaller, gently handled portions.
