Integra Boost 37mm 55% Round Humidity Packs, 3,500 Count
A 37 mm round format at 55% RH, shaped to sit flat in a jar lid rather than folding against a curve. That is the whole argument for a disc. A rectangular packet in a round closure cants across the diameter, takes headspace and ends up resting on the contents. The disc lies in the cap or the liner instead, clear of whatever is underneath. The fill is plant-based glycerin and water, 100% salt-free and 99% biodegradable, so nothing crystallizes onto stored material. Two-way control means a container that has run dry recovers instead of only being held. At 55% it runs the drier of the two storage tiers.
Bulk Round Packs Without Overwrap or Indicator Cards
The case runs 3,500 packs with no overwrap and no humidity indicator cards, which is where the per-unit cost comes down. That also means every pack goes live the moment the case is opened. It suits a continuous packaging run rather than a case dipped into over months. Reseal what a run does not use. On sizing, match the disc to the closure and not to the jar body. The 37 mm is the narrow one, and the 51 mm covers wider lids the 37 leaves gaps around. Pick by the closure the disc has to sit in. For jars sized by weight rather than by closure, the flat packets are the better match on figures alone.
Key Features
- 37 mm Round Format: Sits flat in a jar lid or round tube base instead of folding against the curve.
- 55% RH Two-Way Control: Adds moisture to a container that has dried out and pulls it back when opened.
- 100% Salt-Free Formula: Plant-based glycerin and water, so no salt crystals reach the material it touches.
- 99% Biodegradable, Non-Toxic: Zero off-gases, and spent packs leave with ordinary room waste.
- FDA Compliant, Food Grade Inks: Rated to sit in direct contact with stored product.
- 3,500 Packs per Case: Bulk-packed without overwrap or cards to keep per-unit cost workable at volume.
- Spill-Proof and Tear-Resistant: Stays pliable under handling, so a snagged pack does not empty into a container.
- Drier Than 62% RH: The right level when material is held long term rather than moving quickly.

Why a Round Pack Instead of a Square One?
Round packs sit flat in jar lids and round tubes. A square pack folds against the curve and takes up usable headspace.
What Does No Overwrap and No HIC Mean?
Packs ship bare, without individual wrapping or indicator cards. Lower cost per unit, but the whole case activates once opened.
Should You Run 55% or 62% RH?
55% runs drier and suits long holds and denser material. 62% keeps more moisture in for product moving quickly.
How Long Do These Packs Last Once In Use?
Typically two to four months depending on how often the container is opened and how dry the surrounding air is.
