Integra Boost 51mm 55% Round Humidity Packs, 3,500 Count
A 51 mm round disc at 55% RH, the larger of the two round formats and sized for wider jar lids and tubes. Against the 37 mm the difference is closure diameter and nothing else. Same fill, same setpoint, same bulk configuration. The 51 mm lies flat across a lid the 37 mm would leave gaps around. The 37 mm suits closures the 51 would not seat in at all. Two-way control releases or absorbs moisture with zero off-gas, holding a sealed container steady rather than only slowing it down. The fill is plant-based glycerin and water, 100% salt-free and 99% biodegradable. Nothing crystallizes onto what the disc touches.
Bulk Round Discs Without Overwrap or Indicator Cards
The case runs 3,500 packs bare, with no individual wrapping and no humidity indicator cards. In practice that sets the sequence of work. Open the case, stage what the run needs, and reseal the rest the same day. Discs go into the cap or liner as the closure is fitted, not among the contents. Then the cap goes on and the container is left alone for a day or two to let the air settle. Skip the reseal step and the remaining discs discharge into the room instead of your product. That is where the per-unit saving gets spent. For jars that need a printed indicator, the overwrapped flat packets carry one. These plainly do not.
Key Features
- 51 mm Round Format: Covers a wider lid flat where a 37 mm disc leaves gaps or shifts under the cap.
- 55% RH Two-Way Control: Adds moisture to a container that has dried out and pulls it back when opened.
- Zero Off-Gas: Nothing but water vapor leaves the pack, so stored aroma is unchanged.
- 100% Salt-Free Formula: Plant-based glycerin and water, so no salt crystals reach the material it touches.
- 99% Biodegradable, Non-Toxic: Spent packs leave with ordinary room waste rather than a hazardous stream.
- 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.
- Drier Than 62% RH: The right level when material is held long term rather than moving quickly.

51mm or 37mm — Which Round Pack Do You Need?
51 mm covers a wider lid flat. 37 mm suits smaller jars, where the larger disc would fold against the wall rather than lying flat.
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.
