Understanding Cannabis Flower Characteristics

Sensitivity to Light and Air

Cannabis flowers are sensitive to light and air, which means they can degrade their potency and flavor. This is great news for us because it means we can enjoy the full flavor and potency of the flowers by keeping them in the right conditions. Proper packaging is the perfect solution for minimizing exposure to these elements!

Moisture Control

It’s important to maintain the right moisture level to prevent mold and maintain the flower’s quality. The right packaging can help you control humidity levels effectively!

  • Heat-Sealed Packaging

Heat-sealed packaging is the best way to keep your cannabis products safe from children. It involves sealing the package with heat, creating a strong, tamper-evident seal that is difficult for children to open. This type of packaging does not include easy-open tabs or flaps, making it challenging for children to access the contents. Heat-sealed packages are commonly used for single-use cannabis products, such as pre-rolls or small amounts of flower.

Push-and-Turn Caps: These caps require the user to push down and simultaneously turn to open. This dual action is typically beyond the capability of young children, making it an effective child-resistant feature.

Squeeze-and-Turn Caps:Similar to push-and-turn caps, these require the user to squeeze the sides of the cap while turning it. This type of closure is often used for bottles containing cannabis oils or tinctures.

Slide Locks: These closures involve a sliding mechanism that must be moved in a specific direction to open the package. The complexity of the mechanism makes it difficult for children to open.

Tamper-evident features are essential for cannabis flower packaging. They ensure product integrity and consumer safety by providing clear evidence if the packaging has been opened or altered.

    Benefits: Easy to implement and provides a clear indicator of tampering.
  5. Vacuum-Sealed Packaging:

    Description: Packaging where air is removed to create a tight seal, often accompanied by a tear strip or perforation for opening.

  6. Foil Seals:
    Description: Thin foil seals that are adhered to the top of jars or bottles and must be peeled away to access the contents.

    Usage: Typically used under screw-on caps. The foil must be completely removed to access the product.

    Benefits: Ensures product freshness and tamper evidence, commonly used in food and pharmaceutical industries as well.


Freshness Preservation: Resealable packaging helps maintain the freshness and potency of cannabis products by minimizing exposure to air and moisture. This is particularly important for flower products that can dry out and lose their effectiveness if not properly sealed.

Safety and Spillage Prevention: By allowing consumers to securely close the package after each use, resealable packaging helps prevent accidental spills and product contamination. This ensures that the cannabis remains safe to use over an extended period.

Convenience for Consumers: Resealable packaging offers convenience for consumers who may not use the entire product in one sitting. They can easily open and close the package as needed, making it more user-friendly.


PROTECTION FROM LIGHT: Opaque packaging blocks light, especially UV light, preventing the active ingredients in cannabis flower, such as THC and CBD, from degrading due to light exposure. This maintains the potency and quality of cannabis flowers.

REDUCES OXIDATION: Light accelerates the oxidation process of cannabis flowers, causing them to lose their freshness and flavor. Opaque packaging slows this oxidation process and extends the shelf life of the product.
