At Class Plastics, we have developed rigorous processes to continually improve product quality and ensure regulatory compliance. Our containers are manufactured using the highest quality FDA certified materials, and our testing regime ensures that all our containers are both reliable and guaranteed to last. 
Delivering excellence in product performance and service is paramount to Class Plastics. Our containers are manufactured using only the highest quality, FDA certified materials, and our testing regime ensures that all our containers are both reliable and guaranteed to last.
All containers manufactured by Class Plastics use food grade resin that is both FDA and Australian Dangerous Goods Code approved.
Each production sample we manufacture, undergoes extensive testing and quality control for efficacy and safety to ensure high quality performance and is consistent with our expectations.
Here is an outline of a typical testing regime. 3. Hydraulic Test Additional containers from each production run are filled to capacity and pressurized to 100 KPI for non-dangerous goods, and 200 KPI for dangerous goods. They are then kept in enclosed receptacles and monitored for pressure drop over time. The minimum pass requirement is less than 10% drop in pressure after 30 minutes. 4. Measuring and Shrinking Test Since the plastic is extruded out of the machine at about 190 degrees and is blown in a mould which is cooled to 12 degrees, the containers shrink during the process. The diameter of the neck is measured every 30 minutes while it is cooling, to make sure that the cap will fit well on the neck of the finished container.
The shrinking rate is inevitably higher in the summer months than in winter. So, we apply the caps a little looser during summer and a little tighter during winter. These tests ensure that the caps will fit and work in accordance with the neck of the containers. 5. Stackability Test Some tests are formulated based on customer use. Our standard recommendation for stacking the containers is 2 or 3 rows high. However, some customers require their containers to be stacked higher. We are able to customise our containers based on the customer’s preference and all containers undergo a stackability test to make sure that they meet the customer’s requirement.
Stackability tests run for a minimum of 1-2 weeks, and at any one time we have 4 to 5 products on test to make sure that the containers can withstand the pressure, of stacking layers of containers on top of one another. 6. Dangerous Goods All Class Plastics containers are manufactured from Food Grade Resin and are FDA and Dangerous Good (DG) approved.
Dangerous Goods testing is carried out by a third party, and governed by the National Association of Testing Authorities Australia (NATA).
With all the latest manufacturing techniques, our product output continues to increase.
At the same time that our production becomes more efficient, we continue to adapt and innovate our testing standards to guarantee that our containers are being manufactured to exceed our customers’ standards.
We are happy to work with you to develop tests for your end-use requirements.

Here is an outline of a typical testing regime.Our Testing Process
1. Initial Inspection As soon as the containers come off the manufacturing line, our staff checks each one for any obvious faults or anything that is out of place. Any container that fails this visual inspection is recycled back into the raw materials at the beginning of the manufacturing line. 2. Destructive Test Several containers from each production run are submitted to a destructive test. This test measures the strength and wall thickness of the containers by dissecting the container into 11 different sections to determine the physical properties of the container and ensuring that it meets the industry standard. Ongoing corrections are made to the production equipment where necessary and all tested containers are recycled back into the raw materials at the beginning of the manufacturing line.
3. Hydraulic Test Additional containers from each production run are filled to capacity and pressurized to 100 KPI for non-dangerous goods, and 200 KPI for dangerous goods.
