Evaluation of Free Fall Impact On Cling Film

Cling films or food wraps are an essential part of food and beverage packaging. These are thin films that are used to wrap food and edible products. The thin plastic films are used to seal wrap products efficiently securing them and keeping them fresh and intact. Not commonly but clings films are sometimes used for other products to function and deliver the same properties. Although they have such a versatile use and consumption they are very sensitive to sudden or free-fall impacts. To improve the production line quality one must get the behaviour checked using a dart impact tester.

How a cling film performs under sudden impact?

As said earlier, cling films are very thin sheets of plastic that are further stretched to wrap around the products tightly, making them thinner and sensitive to impact. In case any such wrapped product is stored, transported or mishandled and experience a sudden impact of load free-falling from top, the sheet tends to burst. This damaged film will no longer be able to protect the product and play a role of a barrier between the contaminants and the product.

How one can assure the quality of cling film in the production line?

Dart Impact Tester is the most reliable and highly efficient quality testing equipment that helps the user examine the impact of a free-falling dart on the product, in this case, a cling film.

To attempt the test, the specimen that is the cling film is clamped using a circular sample holder and tightened as per requirement. The clamping mechanism is adjustable to a variety of shapes and sizes. A specified amount of weight is allowed to free-fall from a defined height to test the impact of the fall. A particular height and weight combination is assessed at which the cling will burst out to fail.

The Dart Impact Tester comes with a single dart configuration that allows testing distinct heights and counts of falls. It is a robust design that conforms to international quality test standards like ASTM D-1709 & IS 2508. This ensures that the test report or analysis generated by the machine is accepted all over the world. A number of free-falls or rounds of tests are recorded on a digital display screen. The dart is composed as per the design standards and is held by magnetic technology. The magnetic control over hold and release of dart allows precision-based testing and reduces chances of human error generation. To be specific the controls work on pneumatically controlled electromagnetic technology. The dart holder ensures a stronghold of the dart before a test and a quick release for testing the performance.. The fall height can be easily adjusted as per the test sample or test protocols designed.
