How packaging impacts the shelf life of cannabis products

Good packaging is key to extending the shelf life of cannabis and keeping it fresh longer. Airtight containers and UV-blocking materials protect it from light, air, and moisture. This stops oxidation, which weakens THC and other compounds. Packaging helps maintain the shelf life of cannabis by reducing oxygen and light exposure. Special methods like Modified Atmosphere Packaging (MAP) use safe gases instead of oxygen to enhance its longevity. With the right packaging, cannabis stays tasty, smells good, and works well over time.

In my experience working with cannabis brands, shelf-life issues are one of the top customer complaints. Brands that invest in proper packaging early on not only improve product quality but also reduce returns and build stronger customer loyalty.

Key factors affecting the shelf life of cannabis

Oxygen exposure

Oxygen can make cannabis lose its strength over time. When air touches cannabis, THC and other compounds start to break down. This process, called oxidation, also changes the smell and taste. Over time, this makes the product less effective and enjoyable.

To stop this, store cannabis in airtight containers. These containers keep air out and protect the product. Some advanced methods, like Modified Atmosphere Packaging (MAP), replace air with nitrogen. This slows down the breakdown process even more. Studies show that less oxygen helps keep THC strong and cannabis fresh.

We’ve seen that using nitrogen-flushed packaging solutions can preserve terpene profiles significantly better over a 90-day period compared to regular air-sealed bags. This small step adds real value for premium flower brands.

Humidity and moisture

The amount of moisture in the air affects cannabis quality. Too much moisture can cause mold and bacteria to grow, making it unsafe. Too little moisture can dry out cannabis, reducing its weight and strength.

O best humidity level for cannabis is between 59% and 63%. This range keeps it fresh and strong. You can use special packs to control moisture in storage containers. These packs stop mold and keep cannabis from drying out.

One of our clients began using two-way humidity packs in every jar and received noticeably better customer feedback within weeks. The smell, texture, and grindability were all preserved better, especially during long transit times.

Temperature fluctuations

Changes in temperature can harm cannabis quality. High heat speeds up chemical changes, breaking down THC and terpenes faster. For example, THC can turn into CBN in hot conditions, making cannabis less strong.

The best temperature for storing cannabis is 60°F to 70°F (15°C to 21°C). A cool, steady temperature keeps cannabis fresh. Avoid places that are too hot or cold, as they can damage the product. Research shows cannabis breaks down faster at higher temperatures, with a 3.5% increase in breakdown at 30°C compared to 20°C.

By managing air, moisture, and temperature, you can keep cannabis fresh longer and improve the user experience.

Light exposure

Light can quickly damage cannabis and lower its quality. UV rays are especially harmful, breaking down THC and THCA. This makes cannabis less strong over time. When light hits cannabis, its chemical makeup changes. Extracts break down faster than resin because they lack natural protection.

A study by Lindholst (2010) showed THC lasts longer in darkness. Without light, THC’s half-life increased by 40%, staying stronger longer. But with light, cannabis extracts broke down quickly. THCA almost disappeared after 140 days of light exposure. This proves keeping cannabis away from light is key to keeping it fresh.

In our tests, products stored in amber jars maintained nearly 90% of their original cannabinoid content after 60 days, while those in clear glass showed significant degradation. Choosing UV-blocking materials is an easy win for long-term quality.

Dica: Use UV-resistant or opaque containers to store cannabis. These block harmful light and keep it strong.

Diferentes packaging materials block light in different ways. Amber glass jars and Mylar bags work best. They stop UV rays and protect cannabinoids. Clear glass or plastic lets light in, causing faster damage. For long-term storage, pick packaging that blocks light well.

Storing cannabis in dark places with good packaging helps it last longer. Protecting it from light keeps its strength and flavor intact.

The role of packaging in extending cannabis shelf life

Airtight containers

Airtight containers are important for keeping cannabis fresh. They stop air and moisture from getting in. This helps prevent mold and keeps cannabis strong and effective. Containers like glass jars or metal tins protect cannabis from outside harm. They also block dirt and other unwanted particles.

One packaging mistake we see often is underestimating the seal quality. Even a tiny leak can compromise freshness. We always recommend conducting internal pressure or leak tests before final production.

Research shows airtight containers slow down the breakdown of cannabinoids. For example, Grove Bags’ TerpLoc™ technology works better than regular containers. It controls oxygen levels to create the best storage conditions for cannabis.

UV-resistant materials

Sunlight, especially UV rays, can harm cannabis quickly. UV rays break down THC and other compounds, making cannabis weaker. Using UV-resistant materials like amber jars or Mylar bags protects cannabis from light damage. These materials keep cannabis strong and smelling good.

Studies show UV protection helps cannabis last longer. For example, storing cannabis in the dark keeps its compounds intact. Amber jars block UV rays well, making them great for long-term use. Mylar bags are also lightweight and protect against light effectively.

Dica: Store cannabis in a cool, dark place to keep it fresh.

Humidity control solutions

The right humidity is key to keeping cannabis fresh. Too much moisture can cause mold, while too little dries it out. Special humidity packs help keep moisture levels between 59% and 63%, which is ideal.

Studies prove these packs work well. For example, keeping the right humidity stops terpenes from evaporating and protects cannabinoids. A 2018 study found most cannabis samples had low moisture, which hurt their quality. Using humidity packs prevents this and keeps cannabis fresh and flavorful.

Humidity packs are essential for long-term storage. They help cannabis stay strong, tasty, and aromatic over time.

We recommend using pre-calibrated packs tailored for your product type—whether it’s flower or edibles. One of our customers selling in dry climates saw a 20% drop in customer complaints after integrating these packs into all jars.

Advanced packaging technologies for cannabis shelf-life

Modified atmosphere packaging (MAP)

Modified atmosphere packaging (MAP) is a smart way to keep cannabis fresh. It replaces oxygen with gases like nitrogen. Oxygen makes cannabinoids and terpenes break down faster. This lowers the strength and smell of cannabis. MAP slows this by creating a safe space inside the package. Nitrogen helps protect cannabis, keeping it fresh longer. Without MAP, terpenes can drop by 50% in a month. This method also works well for other items like coffee.

MAP is great for cannabis flowers and edibles. It stops oxidation and keeps the product’s taste and smell. Although MAP needs special tools, its benefits are worth it. Businesses can use it to provide better-quality cannabis products.

While MAP requires some upfront investment, we’ve seen brands in high-end markets like California and Germany use this to differentiate themselves with longer shelf life and better terpene retention claims—backed by lab testing.

Vacuum sealing

Vacuum sealing is another good way to keep cannabis fresh. It removes air from the package, cutting down oxygen exposure. This slows the breakdown of terpenes and THC. Research shows vacuum-sealed cannabis keeps more terpenes and THC than regular packaging. For instance, Grove Bags’ pouches saved 36.72% more terpenes and 7.25% more THC.

Vacuum sealing is best for long-term storage. It stops oxidation and terpene loss, keeping cannabis fresh. But you need strong bags to stop air leaks over time.

We always advise using multi-layer barrier films with reinforced seals when vacuum sealing flower. Thin materials can break under pressure, which defeats the purpose of oxygen control.

Vacuum sealing may not protect soft cannabis flowers from damage, so handle them gently.

Child-resistant and tamper-proof packaging

Child-resistant and tamper-proof packaging keeps cannabis safe and secure. These packages stop kids from opening them but are easy for adults. They use features like push-and-turn caps or squeeze-and-lift lids. Experts test these designs to ensure most adults can open them while kids cannot.

States like California have strict rules for cannabis packaging safety. Tamper-proof seals also stop contamination, giving users peace of mind. Using child-resistant and tamper-proof packaging ensures safety and follows the law. It also keeps the product in good condition.

At Hemployd, we’ve designed packaging with built-in child resistance and tamper evidence in a single step—reducing complexity while meeting legal requirements in Canada and multiple U.S. states.

Nota: As more places legalize cannabis, better packaging is in demand. The cannabis packaging market could grow to $22.10 billion by 2034, with North America leading.
