Class Plastics’ Baritainer uses monolayer barrier technology to decrease permeability compared to standard polyethylene containers, and is a cost-effective alternative to fluorination and metal containers.
What is a Baritainer?
Liquid stored in plastic containers produces moisture and sometimes even leaches out of the container. This is because gas molecules penetrate the surface of the container. This process is called permeation.
Compared to metal and other flexible packaging materials, polyethylene in plastics is highly permeable. Permeability is defined as the amount of liquid vapour or gas molecules that pass through the surface of a solid material. It is a major disadvantage of conventional plastic containers used to store substances like hydrocarbons and high-solvent based products. With these materials, permeability can be high and may even lead to emission of harmful gases that are hazardous to human health.
The Solution
Class Plastics’ Baritainer uses barrier technology to reduce the permeation of liquid from inside our containers from food, chemicals and agricultural products. It is a cost-effective alternative to glass, metal and other fluorinated liquid containers. Its “mono-layer barrier” also provides significant savings as it can increase packing capacity (number of containers on a given footprint) by up to 25%.
We think that plastics are waterproof and impenetrable but this is not true. HDPE (High-Density Polyethylene) in its normal state is permeable. Hydrocarbons and high solvent based products permeate through the surface and walls of containers, and over time these harmful chemicals can leach out of the containers. You end up with product loss and worse, these substances become open to human touch and may cause serious health problems.
One way to reduce the permeability of HDPE containers is to submit the containers to a post-manufacturing treatment process called fluorination. The containers are exposed to fluorine gas to replace some hydrogen atoms with fluorine that then creates a barrier. But while this process has proven effective to reduce permeability, it adds significant cost to the containers.
Class Plastics’ Barrier Technology costs 50% less than post-manufacturing fluorination. While fluorination costs around $6 per unit, the barrier technology costs roughly a $2.50 per unit.
The Baritainer is manufactured by mixing a nylon polymer additive with HDPE. We follow a stringent process to get the right blend of these substances to ensure that our Baritainers are highly resistant to liquids being able to permeate into and out of the container.
This technology is a product of our partnership with a US company, BP Polymers who mould containers and produces the resin that gives our Baritainers the barrier property. Class Plastics is the only company with exclusive rights to manufacture these Baritainers in Australia.
Performance and Testing
Class Plastics Baritainer is available in 10, 15 and 20 litre sizes. It is approved for storing and transporting dangerous goods. Compared to conventional containers, the Baritainer has an increased packing capacity of up to 25% which is definitely a freight saver. It is perfect for hydrocarbons, high solvent based chemicals like trifluralin, and aromatic flavours and ingredients.
Each Baritainer undergoes extensive testing and quality control for efficacy and safety to ensure high quality performance consistent with our expectations of our products and serving our customers.
One of our customers tested the Baritainer for over six months and reported no product loss and no signs of permeation. This in turn has provided them with additional revenue because they were able to sell more of their products and save on freight.
Customers who are planning to shift to the Baritainer can contact us for free samples and we encourage them to test our product by doing the following:
- Fill half a dozen or a dozen containers with high solvent or products that are known to permeate conventional HDPE containers
- Mark a level to measure how much it is filled.
- Stick a label onto to the the container.
- Stack the containers in a corner for certain amount of time.
- If there is permeation, you will notice that level or the amount of the liquid drops and the sticker label will also start to bubble and peel off.
We also encourage you to test and use the Baritainer to transport your product and see its additional benefits.
The Baritainer is another product of Class Plastics’ commitment to continually seek quality solutions and innovative products. It is the new industry standard when it comes to plastic packaging containers.
