SYMYNELEC Mylar Kit Review: 100 Bags, 400 cc Absorbers, 11.8 Mil

- No paid placements
The SYMYNELEC kit is a strong all-round mylar kit on paper: 35 gallon, 45 quart and 20 half-pint food-grade bags, 11.8 mil at the gallon size, zip tops, labels and 400 cc absorbers. Its weak point is the count: 55 absorbers for 100 bags, so you will need a refill pack to fill every bag.

The SYMYNELEC kit is 100 food-grade mylar bags in three sizes with 55 oxygen absorbers of 400 cc. On paper, it is one of the most complete kits for a first long-term pantry. We have not packed food in it ourselves: everything below comes from the official Amazon listing and our own math.
SYMYNELEC 100 Mylar bags + 55 × 400cc absorbers kit
100 bags · 11.8 mil · 55 × 400 cc
9/10 · DryFoodLab scoreThe SYMYNELEC kit gets the mix of sizes right. Gallon bags take bulk staples, quarts suit everyday portions and half pints handle spices, seeds or small treats. The listing declares food-grade material in three layers (PET, aluminum foil and PE), a resealable zipper and 100 labels. The 400 cc absorbers are individually sealed, so you can open them one at a time. The problem is arithmetic: 55 absorbers do not cover 100 bags, and gallon bags of light food need two. Budget for a refill pack from the start. The listing also contradicts itself in small ways, which we detail below.
Pros
- 35 gallon, 45 quart and 20 half-pint bags
- 11.8 mil gallon bags, food grade, zip tops
- 400 cc absorbers, individually sealed, plus 100 labels
Cons
- 55 absorbers for 100 bags
- Small inconsistencies in label count, sizes and per-side thickness
- Best for
- A first pantry of rice, beans, oats and freeze-dried food in mixed portions
- Skip it if
- Filling all 100 bags at once without buying more absorbers

What is in the box?
100 bags in three sizes, 55 absorbers of 400 cc and labels. The split, according to the listing:
| Size | Count | Dimensions | Thickness | Nominal volume |
|---|---|---|---|---|
| 1 gallon | 35 | 10.2 × 13.8 in (26 × 35 cm) | 11.8 mil | about 3.8 L |
| 1 quart | 45 | 7.1 × 10.2 in (18 × 26 cm) | 9.4 mil | about 0.95 L |
| ½ pint | 20 | 4.3 × 6.3 in (11 × 16 cm) | 9 mil | about 0.24 L |
Adding the nominal volumes, the kit holds roughly 35 × 3.8 + 45 × 0.95 + 20 × 0.24 ≈ 180 liters (about 47 gallons) of dry food. Real capacity depends on how full you fill each bag, since you must leave room at the top to seal.
Are the 55 absorbers enough?
No, not for all 100 bags. At one absorber per bag, you are 45 short before you even consider light foods.
Use the 21% rule: air left in the bag × 0.21 = oxygen to remove. For a gallon bag (3.8 L):
- Rice, sugar or flour (about 35% air): 3.8 × 0.35 × 0.21 ≈ 0.279 L, or 279 ml. One 400 cc absorber covers it with margin.
- Pasta, beans or oats (about 60% air): 3.8 × 0.6 × 0.21 ≈ 479 ml. One 400 cc absorber falls short; use two.
- Freeze-dried food (about 80% air): 3.8 × 0.8 × 0.21 ≈ 638 ml. Use two.
A quart bag needs at most about 160 ml of oxygen removed, so one 400 cc absorber is plenty. A half-pint bag needs only 17-40 ml, so a 400 cc absorber is oversized there, but it does no harm.
Here is what a full pack-out looks like. With rice in every gallon bag, you need 35 + 45 + 20 = 100 absorbers, so 45 more than the box holds. With beans or pasta in the gallon bags, you need 70 + 45 + 20 = 135, so 80 more. Our oxygen absorber calculator runs this for any size, and the how many oxygen absorbers guide explains the rule.
How thick and strong are the bags?
Thick for a kit: 11.8 mil at the gallon size, 9-9.4 mil for the smaller bags. Bags of 5-7 mil or more are the usual choice for long-term storage, so all three sizes clear that bar.
The catch is how the listing states it. It says 11.8 mil thickness with a maximum of 4.7 mil on each side. Two walls of 4.7 mil make 9.4, not 11.8. We use the 11.8 figure the listing gives as the total, but treat the exact number with caution. Compare other bags in thick mylar bags.
What about zip tops, labels and food grade?
All three are declared: resealable zippers, 100 labels and food-grade material. The zipper is useful once a bag is open, for example a quart of oats you use over a few weeks.
For storage, you still need to heat seal each bag above the zip. The listing’s own spec table says 112 labels instead of 100, and gives sizes rounded to 10 × 14, 7 × 10 and 4 × 6 in. These are small differences, but they show the listing was not carefully checked.
What does the listing leave out?
It does not say how the absorbers are packed beyond individual sealing, and it gives no guidance on absorber size per bag.
- Absorber sizing: there is no chart matching the 400 cc absorber to each bag size and food.
- Heat sealing: no recommended sealer or iron temperature.
- Thickness method: the total and per-side figures do not match.
- Label count and sizes: bullets and spec table disagree slightly.
For the full packing process, read long-term food storage step by step.
