The container is part of how a product is stored, but it is not enough on its own to guarantee its quality. The stability of cannabis depends in particular on light, heat, humidity and oxidation. These factors interact: there is no single rule that would suit every preparation.
the container isn't everything
Packaging should be assessed together with the product it is meant for. Presenting glass as always superior, plastic as always unsuitable, or vacuum sealing as completely stopping degradation would be too categorical. General stability data do not amount to a comparative test of every packaging available.
humidity: avoiding false guarantees
A stated humidity range is not enough, on its own, to guarantee the absence of mould. Likewise, the references used here do not justify condemning all humidity-control packs. Whether to use them should be judged according to the product and its manufacturer's instructions.
a practical guide
For a hi lab product, first refer to the instructions on its packaging. If in doubt about its condition, contact us rather than relying on a universal storage promise. This article explains the limits of general advice; it sets neither an extra shelf life nor a health guarantee.
