Cannabis tinctures (alcohol-, oil-, or glycerin-based) require secure, compliant, and user-friendly packaging to maintain potency, prevent contamination, and meet legal requirements. Best CR Packaging Options 1. Glass dropper bottles with CR caps (most common). 2. Plastic Boston round bottles with CR closures (budget-friendly). 3. Screw-top bottles with CR outer packaging (e.g., a CR box or pouch).
