Simple barrier films are sufficient
packaging for products such as
confections that are not susceptible
to spoilage because of their low water
content. For products where there is
potential for spoilage or microbial
growth, oxygen barriers are needed.
Packaging for cannabis flower should
protect the contents from light and
have a true vacuum seal. Beverages and
concentrates should be refrigerated to
keep them in prime condition.
Appropriate packaging also is crucial
Some extracts are quite durable,
Farrar said. Gummies made with
distillates have a long shelf life as long
as they're not left in a hot car. Extracts
such as live resins and rosins don't get
better with age. However, resins stored
in a cool, dark spot should have a fairly
lengthy shelf life.
THE ROLE OF PACKAGING
Packaging plays a key function in
the shelf life and safety of cannabis
products. It provides a barrier to the
surrounding environment, keeping
contents sanitary and microbe free. It
also prevents oxidization and, in the
case of beverages, stops ultraviolet light
from attacking liquids.
" Since packaging is the only physical
barrier between the product and the
outside environment, its importance
should not be underestimated, "
Hathaway said. " Ideal packaging will
prevent the food product from being
exposed to external oxygen, moisture
and light, as all three aspects can
negatively affect a product's chemical,
microbial and physical stability. "
for THC- and CBD-infused topical
items such as lotions and salves, said
Kat Merryfield, founder of Dunlap,
Tennessee-based Kat's Naturals, which
produces a line of CBD products.
Merryfield's packaging is modeled
after the cosmetics industry. The
double-walled jars used for Kat's
Naturals CBD creams withstand heat,
and its tinctures are in dark bottles.
" If people are using water-based
lotions, they should be in pumps or
squirt bottles, " Merryfield said. " Water
holds all kinds of bacteria. Once that gets
in the oil, it begins to grow. "
Labels on packaging should have basic
instructions for how to properly store the
products.
