Importance of placing specimen accurately on dart impact tester

05-7-2022
Plastic film is a ubiquitous material in today's packaging industry. These films are lightweight, and versatile, making them an ideal choice for a wide range of packaging applications. These films can be used to wrap delicate items, line boxes, or create bags and pouches. It is also frequently used as a barrier material to protect products from moisture, dust, and other contaminants. Thus, testing the dart of these films is of utmost importance to make sure that your package will withstand free-falling darts. Presto has come up with one of the amazing lab testing instruments known as a dart impact tester which is helpful in measuring the strength of plastic films to withstand the falling dart. The prima model of this testing equipment will come with an electromagnetic dart hold/release mechanism to avoid any type of interference in force exertion.
