Product Overview
The ZRLEI 400cc Oxygen Absorbers are a 100 count set packaged as 20 packs of 5, made for long-term food storage in Mylar bags and other airtight containers.
This review checks the food-grade construction, 400cc capacity, packaging format, and the common expectation around bag shrinkage.
Score Breakdown
This verdict is based on the manufacturer's stated specifications, the current Amazon listing and its product images, the confirmed materials and design, real buyer ratings, and our research into the product category. Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
Absorbers are packaged in sets of five and heat sealed immediately after production, never repackaged, to limit oxygen exposure and maintain potency.
Made with food-grade packaging that has passed strict food testing for safe contact with stored foods.
Designed for 1-gallon Mylar bags and other airtight containers to help extend shelf life of dry goods.
Features a double layer and anti oil film design for added protection during storage.
Absorbers remove oxygen, about 20 percent of air volume, so bags will not shrink like vacuum bags, and 4/5 of air remains.
Design and Build Quality
ZRLEI uses food-grade packaging that has passed strict food testing, with a double layer and anti oil film design. The absorbers are packed in sets of five and heat sealed immediately after production to protect against early oxygen exposure.
The listing does not confirm item dimensions or weight, so the main physical details are the 400cc size and the 100 count total.
Performance in Everyday Use
A 400cc absorber is suited to 1-gallon Mylar bags and airtight containers for grains, beans, powders, pasta, cereal, and dehydrated or freeze-dried foods. The five-pack format helps users open only what they need for a single storage session.
The key limitation is that oxygen absorbers do not remove air. Oxygen is about 20 percent of air, so only about 1/5 of the air volume will be gone after absorption, and bags will not shrink like vacuum bags no matter how many absorbers are used.
How It Performs: The Evidence
| Decision factor | What we found | Evidence and measurement | Score | Why it matters |
|---|---|---|---|---|
| Food safety | Food-grade packaging, strict food testing | Listing states food-grade material and passed strict food testing | 8.5 | Strong food contact assurance, though no third-party cert details are given |
| Oxygen capacity | 400cc | Listing states 400cc capacity for 1-gallon Mylar bags | 8.0 | Good match for common dry goods containers |
| Packaging freshness | 20 packs of 5, heat sealed | Bullet says absorbers packaged and heat sealed immediately after production, never repackaged | 9.0 | Reduces exposure if you open only one pack at a time |
| Air removal expectation | Absorbs oxygen only, not air | Bullet notes about 1/5 of air volume will be gone, 4/5 remains | 6.0 | Users expecting vacuum bag shrink will be disappointed |
| Construction | Double layer and anti oil film | Bullet lists double layer and anti oil film design | 8.0 | Adds durability but long-term performance not rated |
Who Should Buy It
- Preppers stocking grains and beans
- Freeze dryer and dehydrator users
- Mylar bag and canning storage
- Pantry rotation for pasta, cereal, and powders
- Long-term survival food planning
- Anyone expecting vacuum-sealed bag shrinkage or needing smaller pack counts.
- Absorbs oxygen only, so bags will not shrink like vacuum bags

How It Compares
| Feature | ZRLEI | Typical option | Higher-tier option |
|---|---|---|---|
| Packaging format | 20 packs of 5, heat sealed after production | Often one bulk pack or loose count | Single-use or smaller packs |
| Oxygen capacity | 400cc | Typically 300cc to 500cc | 100cc or 200cc for smaller containers |
| Food contact safety | Food-grade material, strict food testing | Food-grade plastic or paper wrapper | May use simpler packaging without stated testing |
| Compatibility | 1-gallon Mylar bags and airtight containers | Similar for medium to large dry storage | Small jars or single meal pouches |
| Air removal behavior | Absorbs oxygen only, not air | Same oxygen-only mechanism | Vacuum sealing removes air volume |
| Shelf life protection | Five-packs never repackaged to limit exposure | May be bulk packed and repackaged | Oxygen absorber packets with indicator tabs |
Alternatives Worth a Look



This is a practical set of food-grade 400cc oxygen absorbers for long-term dry food storage. The five-pack format and immediate heat sealing support potency, but expect normal non-vacuum bag behavior.

This review is based on the manufacturer's stated specifications, the current Amazon product listing and its images, the confirmed materials and design, and our own research into food storage and preservation as a product category. Our scores are editorial judgments made against consistent criteria, not laboratory measurements, and we did not carry out destructive or long-term stress testing.
Where the listing did not clearly confirm a detail, such as exact dimensions, weight or certifications, we have deliberately left it out rather than guess. If you are buying, always confirm the current specification and price on the live Amazon listing, since configurations and availability change.
