Are you currently working directly with Chinese or other overseas manufacturers? Most likely they won't be able to solve your traffic problem. This may be because these suppliers lack the materials needed to get the details right.
Also, when you work with overseas or inexperienced suppliers. You face miscommunication and distance from plain and simple. When your suppliers are located halfway around the world, it can be difficult to find a way to experiment with various orifice sizes, dropper insert materials, and rigid bottle sizes in-house.
Another factor that hinders perfect flow is the dropper construction. Each manufacturer sets its own dimensions thanks to the inserts and proprietary molds for rigid bottles. So when you choose a different supplier, they will need to complete test runs and experiment with flow rates. Dropper inserts that work for one brand simply don't work for all.
The same goes for choosing essential oils. Going back to the viscosity rate, some essential oil blends will change the overall viscosity, creating a thinner or thicker flow.
At Carow in the United States, we offer convenience and accessibility. Our mission is to provide you with the materials you need so you can provide your customers with efficient essential oil applications.
If your current packaging provider doesn't provide you with an analysis of your dropper details, you could be missing out on an incredible quality assurance step in your business.
