Integra Boost 4g 55% Humidity Packs Suit Half-Ounce Containers
This is the one you drop into a jar and forget about. A single 4 g packet, 2in x 2.375in, sealed in its own overwrap with an indicator card inside. It lies flat under a lid or against a jar wall without stealing volume that should hold product. At 55% RH it runs the drier of the two storage tiers, which suits denser material and anything going into a long hold. The fill is plant-based glycerin and water, salt-free, so nothing crystallizes onto whatever rests against it. The card in the wrapper is what makes this a single rather than a bulk packet: its dot turns blue when the pack is spent.
Single Humidity Packs for Jars, and Matching the Size to the Fill
Sizing is the whole decision, and it goes by contents rather than by container. A 4 g packet covers up to 12 g, which is the half-ounce jar. Below that, the 1 g handles an eighth and suits a vial or a pop-top. Above it, the 8 g covers a full ounce and the 67 g covers a pound in a bin or a turkey bag. An oversized packet in a small headspace is money doing nothing, and an undersized one spends itself keeping up. Singles have obvious economics. This is the format for topping up one jar, not for running a line. The bulk cases exist for that, at a fraction of the cost per packet. If you need more than a handful, the 600 count and 1,000 count cases are the sensible answer.
Key Features
- 55% RH Two-Way Control: Pulls a small jar toward 55% and holds it, rather than only adding or only removing water.
- Covers Up To 12 g: One pack per eighth jar or small pouch, where an 8 g pack would overshoot.
- Individually Overwrapped: Stays inert on the shelf and starts only when you tear the wrapper at fill.
- Replacement Indicator Card Included: The card's dot turns blue when the pack is finished, so replacement is not guessed.
- Built for Long Holds: The lower setpoint leaves margin against moisture creep across a long storage window.
- 100% Salt-Free Formula: Plant-based glycerin and water, so no salt crystals transfer to what it touches.
- Spill-Proof and Tear-Resistant: Stays pliable in a jar opened daily without splitting at a crease.
- FDA Compliant, Food Grade Inks: Cleared for direct contact with stored product, which is how it gets used.
- 2" x 2.375" Format: Small enough for an eighth jar, where a larger packet crowds the contents.
- 2 Year Shelf Life: Overwrapped stock keeps, so holding a few ahead does not cost you packs to age.

How Much Does a 4g Pack Cover?
Up to 12 g. The 8 g size covers a full ounce, and the 67 g covers a pound.
Should You Use 55% or 62% RH?
55% for long holds, dense material and humid rooms. 62% for anything being consumed within weeks, where texture and aroma matter more than margin.
Is This Sold as a Case?
No. This is a single packet. The bulk configurations are separate listings, running 600 or 1,000 packets per case.
How Long Does One Pack Last?
Two to four months in a jar opened a few times a week. The indicator card dot turning blue is the signal to swap it, not the calendar.
