What it is
Moisture protection limits water, vapour, condensation or humidity exposure to a level the product can tolerate for the required period.
When it is relevant
Relevant for hygroscopic materials, electronics, powders, coated parts, paper-based goods and routes with temperature or humidity transitions.
Risks and problems addressed
Ingress, vapour diffusion and condensation can cause swelling, caking, corrosion, insulation failure, mould or loss of appearance.
Product characteristics that matter
Record moisture sensitivity, equilibrium or critical humidity if known, exposed materials, coatings, vents, residual moisture and allowable drying methods.
Logistics and environmental factors
Map rainfall or splash exposure, climate-zone changes, unconditioned storage, container dwell, opening events and total protection time.
Information a packaging supplier needs
Give the supplier the tolerated exposure, route climate, duration, opening pattern, seal constraints, verification method and whether indicators are required.
Common mistakes
Do not treat waterproof and vapour-tight as the same property, and do not ignore moisture introduced by the product or packing environment.
Relevant standards and regulations
Select any standard from the actual product, route and verification objective. Consult the current official publication; summaries do not replace a standard or engineering validation.
RFQ
What a useful specification contains
Give the supplier the tolerated exposure, route climate, duration, opening pattern, seal constraints, verification method and whether indicators are required.
Frequently asked questions
How do I know whether moisture-protection packaging is relevant?
Relevant for hygroscopic materials, electronics, powders, coated parts, paper-based goods and routes with temperature or humidity transitions.
What should I give a packaging supplier?
Give the supplier the tolerated exposure, route climate, duration, opening pattern, seal constraints, verification method and whether indicators are required.
Does PackNavi choose a packaging technology here?
No. PackNavi captures conditions, required outcomes and open points. A suitable technology must be engineered and validated for the actual product and supply chain.
