What are the main packaging options for infused cannabis product companies?

The answer to your question is not simple.  There are different types of child resistant packages for single dose/use products vs. multi dose products.  The cannabis packaging industry is coming up with new solutions all the time.  We have the basic stock bottles and bags/pouches, but there are also new reclosable boxes that are paperboard as well as plastic, blister packages and more.  You can customize stock packages as well as develop your own custom package for your specific product.   Part of your packaging choice should be based around your production process and what package best fits your operation and assembly goals.  
These are the technical issues, but there are also branding needs that will drive the package you choose to distinguish your product in the market.  Find the right packaging supplier to help you meet your goals.
