Integra Boost 51MM ROUND 62% PACKS. NO OVER WRAP OR HIC CARDS INCLUDED.. 3500 Total Qty.

Integra Boost 51mm Round Humidity Packs Sit Flat in a Jar Lid A rectangle and a disc solve the same problem in different places. The rectangle lies among the contents; the disc seats inside a screw cap or a lid liner, above them. That is the whole argument for the round format, and it matters most for anything that marks, compresses or sticks to a flat packet. This is the 51 mm size, covering up to 7 g and holding 62% RH. It will also sit among the contents if a closure has no room. The lid position is an option rather than a requirement. The fill is the ordinary Integra blend, plant-based glycerin and water with no salt in it. Round Humidity Packs for Jars, and Picking a Diameter Diameter follows the closure, and coverage follows the contents, and the two do not always agree. The 51 mm lies flat across a wide-mouth cap where a smaller disc would leave gaps. Integra makes the discs in 37 mm, 45 mm and 51 mm diameters. Both smaller discs cover 3.5 g, so stepping down in diameter also steps down in capacity. If the cap is wide but the jar holds an eighth, the 51 mm is more pack than the job needs. Check a disc against your own closure before running a full case. This one ships 3,500 packets loose, with no overwrap and no indicator cards. The whole case goes live the moment it is opened, so plan the run before cutting into it. Key Features 51 mm Round Format: Seats inside a screw cap or lid liner instead of lying loose among the contents. Covers Up To 7 g: Matched to a small jar, roughly double what the 37 mm disc handles. 62% RH Two-Way Control: Adds moisture to a jar that has dried down and pulls it back after the lid has been off. Can Keep the Pack Off the Product: Lid mounting suits anything that marks, compresses or sticks to a flat packet. 3,500 Packets Per Master Case: Line volume for a capping or packaging operation rather than single jars. No Overwrap, No Indicator Card: The bulk trade-off that brings the per-packet cost down for line work. 100% Salt-Free Formula: Plant-based glycerin and water, so no salt residue transfers to the contents. Spill-Proof and Tear-Resistant: Stays pliable through automated capping and hand assembly without splitting. FDA Compliant, Food Grade Inks: Cleared to sit in direct contact with the product it is packed beside. Also Made at 37 mm: The smaller disc covers 3.5 g, for narrower closures and single-eighth containers.

Manufacturer Part Number B51M62J Documentation ISO and QPL documentation available from the manufacturer on request SKU B51M62J Why Use a Round Pack Instead of a Rectangle? It can seat inside a lid. A rectangular pack folds against a round closure and takes up headspace, so it has to sit among the contents. How Much Does a 51mm Disc Cover? Up to 7 g. The 37 mm disc covers 3.5 g, so the choice follows container size rather than closure diameter alone. Does This Case Include Indicator Cards? No. Packets ship loose with no individual wrapper and no cards. Will a 51mm Disc Fit Any Lid? It suits wider closures where the smaller disc leaves gaps. Check it against your own cap before committing to a full case.
