Evaluate the Behavior of Plastic Caps under Weathering Conditions

Millions of plastic bottles are utilized for distinct purposes. PET bottle industry have grown gradually with increase in demand by the market. The plastic bottle caps are also similarly manufactured in trillions basis at one time to fulfill the demand. With such high demand of production, how much time a manufacturer may invest in its quality checks? Have you wondered that why some bottles are low priced and some may not look costly but are highly priced. This difference is because of the quality standards which are maintained.

The PET Bottle caps also must undergo several quality assurance tests. The caps due to on the external part of the bottle faces the surrounding environment more than the bottle itself. With time and its use if the quality standards of the material is not good enough to stand the weathering agents, it will lose its color, its strength and tends to generate cracks over it.

What solution lies for the manufacturer so that he can assure that the PET bottle cap he is producing maintain its strength for long and must retain the quality at production? The solution is a weathering test. A weathering resistance testing machine can be used to check the quality of the material used for producing caps or the manufactured caps itself. The testing machine will produce range of weathering agents with defined time intervals and speed to see if the cap can sustain the expected environmental factors or not.

Presto, the leading name in test equipment has designed a latest generation UV Light Accelerated Weathering Tester which is a bench top model making it easy to use. The model is touch screen version which allow the user to access all the operations and test result data at their fingertips. It can produce damaging weathering conditions such as rain, moisture, heat, direct sunlight, effects of UV radiations etc.

The machine has very comfortable test specimen placements. One can also access the test data via hard drives and transfer it to other devices. To use it for the test, the user must place the test specimen, in this case bottle caps inside and lock the door. The test can be programmed as per use and industry requirement and then can be initiated. After the given time interval the machine will be stopped automatically and you can access the testing data from the display screen.
