The shelf life and storage tips of unopened e-cigarettes
General shelf life: Unopened e-cigarette cartridges or devices, under reasonable storage conditions, usually have a shelf life of 12 to 18 months. The specific duration may vary slightly due to brand, production process and storage environment. For instance, the shelf life of Relx cartrittles is generally 12 to 18 months, while the shelf life of some disposable e-cigarettes may be as long as one year.
Factors affecting the shelf life:
Storage environment: High temperature, humidity and direct sunlight will accelerate the decomposition of e-liquid components and shorten its shelf life.
Product type: The shelf life of e-liquid cartridges is usually shorter than that of the equipment itself because the components of their e-liquid are more susceptible to environmental influences.
Temperature control
Suitable range: The storage temperature should be controlled between 10℃ and 30℃ to avoid high temperatures (such as in a car or near a radiator) causing the e-liquid to expand and leak, or low temperatures (such as in a refrigerator) causing condensation.
Extreme temperature risk: High temperatures may accelerate the decomposition of e-liquid components, while low temperatures may increase the viscosity of e-liquid, affecting the atomization effect.
Humidity management
Suitable range: The humidity of the storage environment should be below 70% to prevent the e-liquid from getting damp and causing short circuits in the circuit or deterioration of the e-liquid.
Moisture-proof measures: Store in a sealed container and add food-grade desiccants (such as silica gel bags) to absorb excess moisture.
Store away from light
Ultraviolet protection: Ultraviolet rays in sunlight can accelerate the decomposition of nicotine and flavoring in e-liquid, resulting in a poor taste. It is recommended to store in dark containers or light-proof bags to avoid direct sunlight.
Seal and store
Anti-oxidation: Unopened e-liquids should be kept in their original sealed packaging to prevent oxygen in the air from oxidizing the e-liquid components, which could cause the color to deepen and the taste to become bitter.
Leak prevention: Ensure that the packaging is undamaged to prevent e-liquid leakage.
Storage location
Safe location: Store e-cigarettes out of the reach of children to prevent accidental ingestion or misoperation.
Stay away from pollution sources: Avoid storing together with food, medicine, etc., to prevent cross-contamination of odors or contamination.
Regular inspection: Even if unopened, it is necessary to regularly check whether the packaging of the cartridges or equipment is intact and whether there are any abnormal phenomena such as leakage or gas expansion.
Follow the production date: Give priority to using products that are close to their expiration dates to avoid expiration due to long-term storage.
After opening, the shelf life: Once opened, it is recommended that the cartridges be used up within 15 days to 3 months, with the specific time varying by brand.
