The starting point was to study some of the commonest packaging types and compare the differences in climate impact depending on the choice of packaging material. “There are tables giving carbon dioxide emissions per kilo of material, but when you compare real examples of packaging, you realise the great importance of the choice of material,” comments Johan Granås, Sustainability Director at Iggesund Paperboard. “Plastic is a fantastic material for many applications and we use it ourselves when producing paperboard for food packaging that needs a thin plastic barrier to protect its contents,” he adds. “But we believe that decision makers in the packaging industry must know about the effects of their choice of material.” Packaging light bulbs in plastic or paperboard respectively is the most extreme example in the survey. By switching from plastic to paperboard, it is possible to reduce the climate impact of the packaging by 99 per cent. Click read more below for additional detail.
A new set of resources released by the California Department of Public Health (CDPH) offers a checklist with the Dos and Don’ts of cannabis packaging in the state, along with labeling instructions.
- Package manufactured cannabis products prior to transfer to a distributor as a finished product. Cannabis flower may be packaged by a cultivator, manufacturer or distributor.
- If a product has multiple layers of packaging, the packaging requirements can be fulfilled using any one of those layers.
- Cannot imitate packaging used for non-cannabis food products or products typically marketed to children.
The four main criteria for a package to meet are tamper evidence, child-resistance, resealability (for products with multiple uses) and opaque packaging for edibles.
Only edibles must be packaged in “lifetime” child-resistant packaging (child-resistant after opening and reclosing), while other forms of products must be initially child-resistant, upon first opening.
Additionally, a labeling checklist specifies what info can and cannot be included. The product’s county of origin can not appear anywhere on the label unless 100% of the cannabis in the product was grown there. Labels are also forbidden from making unproven health claims.
