FreshSeal
Vacuum Sealing

Oxygen drives oxidation. Oxidation degrades flavour. FreshSeal removes the oxygen at the point of pack and keeps your powder flavours within specification through storage and transit.

The Chemistry

Oxygen Is the Problem

Volatile flavour compounds react with oxygen the moment they are exposed to air. The reaction is slow at room temperature but unavoidable, and it accumulates over weeks and months on a warehouse shelf. The result: top notes flatten, potency drops, colour shifts, and consumers taste a degraded product.

FreshSeal removes oxygen at the moment of pack. A vacuum is pulled and the seal is set before air can re-enter. With the substrate gone, the oxidation reaction has no fuel to continue. Shelf life follows accordingly.

What You Get

Oxygen Eliminated, Shelf Life Held

Vacuum sealing calibrated to your product, validated by accelerated shelf-life testing.

01

Oxygen Removal at Seal

Controlled atmosphere extraction immediately before the final seal pulls residual oxygen from the package headspace. Less oxygen means slower oxidative degradation of volatile flavour compounds.

02

Consistent Per-Unit Vacuum

Calibrated vacuum levels across every package regardless of batch size or product density. Uniform protection means a uniform shelf life, with no outlier units that arrive degraded.

03

Slowed Oxidative Reactions

Oxidation is the dominant degradation pathway for stored flavour powders. Top notes flatten. Colour shifts. Potency drops. Removing oxygen at pack time removes the substrate the reaction needs.

04

ASLT-Backed Shelf-Life Data

Accelerated Shelf-Life Testing in our R&D lab generates the time-temperature-humidity data behind each product's claimed shelf life. The number on the spec sheet is the number that the test proved.

Our Process

How FreshSeal Works

From headspace mapping to validated shelf life, four steps.

01

Headspace Mapping

We measure the headspace shape and target vacuum level needed for your specific powder and packaging combination.

02

Vacuum Calibration

FreshSeal pulls and verifies vacuum on every unit. Repeatable across thousands of packs at production rates.

03

Sealed and Tagged

Sealed units leave the line with a verified seal integrity check. Tagged for traceability against the certificate of analysis.

04

ASLT Validation

Sample packs run through our R&D Accelerated Shelf-Life Testing chamber. Real data behind the shelf life on the label.
