Tips on how to fill this container?
When filling quite viscous/thick products that have required heating e.g. cream, you will experience that it is difficult to fill into a jar if the product has been cooled down to room temperature.
If it is at room temperature you will most likely need to spoon it into a jar - the problem with that is that the products will not look smooth on the top.
To avoid this, fill your jars when the product is cooling down (approx. between 40 - 30 degrees Celsius.
If that is not possible you can reheat the product until it becomes pourable. If the product is pourable it best filled with a spouted beaker or jug.
Make sure that you don't overfill your jars.
If you do, then, when pressing down the liner the product spill out from under the liner.
