Standard HDPE jerrycans, bottles, … are not suitable for every product due to the fact that the material and product can interact. There are various reasons for this:
- Penetration/migration of the product
- Evaporation of the product
- Weakening of the packaging material
Needless to say, such issues can cause problems. Think of :
- Changes in the product due to the evaporation of some component within it
- Labels falling off the wall
- Packaging collapsing or inflating
- Odour problems
Fortunately, for every problem there is a solution. Feel free to contact us to find the solution that suits you.
Fluorination
Adding fluorine creates a PTFE (polytetrafluoroethylene) layer which acts as an additional barrier. There are 2 options: either during production or afterwards.
Inline fluorination
During production, fluorine is added into the mould (inline), this has the following advantages:
- Uses HDPE which is widely available.
- The barrier is formed by a chemical modification of the inner wall only.
- Can be recycled as ordinary HDPE
- It is a continuous production process that retains the dimensional and visual aspects.
Fluorination after the production of the bottle
Fluorine atoms are added to the inner surface of the packaging afterwards.
Multilayered bottles OEX PE/EVOH AND PE/PA
This type of bottle consists of several layers of HDPE and one or more barrier layers.
- COEX (PE/PA) is an impermeable contact barrier. Making it suitable for solvents, oils, agrochemicals, adhesives, paints and even inks.
- EVOH, on the other hand, is a so-called “sandwich barrier”, which is suitable for the food and pharmaceutical industry. Its structure, among other things, contributes to the optimum protection of the bottle against oxidation, moisture and other aggressive external factors.

Since we have no information either on the composition of the product to be filled by your company or the circumstances under which this will take place, or on the method of transport of the filled packaging and their accessories, we are not in a position to give any definite opinion regarding the compatibility with the materials used. At all times, the customer remains responsible for any damage or defects. We therefore recommend that, in your own interest, product compatibility tests as well as stability tests be carried out.
