Storage, packaging, and light protection

How packaging systems co-determine real product quality and why storage is a core part of quality assurance.

Enemies

Light, oxygen, heat

Lever

Suitable packaging

Practice

Observing changes over time yourself

Key points

Product quality doesn't end at the COA — it depends heavily on storage and packaging choice.
Light, oxygen, and temperature significantly affect profile and shelf life.
Good packaging is part of the quality system, not just marketing.

Why packaging is more than a shell

Packaging materials co-determine how stable aroma, cannabinoid profile, and microbiological safety remain over time.

Especially for high-quality products, this is a direct quality lever.

Which questions good storage answers

How old is the batch, how was it transported, and was it exposed to light or heat? These points should never stay invisible.

Only once you consider this together with the actual condition and, if available, a lab value, do you recognize patterns.

Checklist

Choose packaging by product class
Document storage and transport conditions
Compare profile loss with packaging tests

Frequently asked questions

Is glass always the best packaging?

Not automatically. Protective effect, headspace, handling, and supply chain must be considered together.

Why doesn't a lab value from time of purchase serve as a permanent guarantee?

Because quality can change after the test due to light, heat, or incorrect storage - the lab value applies to the time of the sample, not forever.
