For fresh market direct to the customer you can go as simple as rubber banding together 7 to 10 stems.

For packaging for stores I have used ziplock bags with a decent looking lable on the bag.Works well and is reasonably cheap.

Monte packaging should have the plastic containers but such an expensive container will cut deeply into your bottom line.
