Na str\u00e1nk\u00e1ch Tester smr\u0161t\u011bn\u00ed f\u00f3lie<\/strong> is an essential instrument designed to measure the shrink forces and shrinkage ratios of heat shrinkable films<\/a>. These films are commonly used in various industries, including packaging, food, medical, and pharmaceuticals. Manufactured through extrusion and stretching (hot drawing), these films maintain a stretched state until reheated. When exposed to the specific temperatures that release the initial stress, the films contract, or “shrink back,” making accurate measurement critical for quality assurance.<\/p>\n

Proces testov\u00e1n\u00ed<\/h3>\n
    \n
  1. P\u0159\u00edprava<\/strong>: The testing begins with a well-insulated air oven, which is heated to a predetermined temperature. Two samples are placed separately on designated test stations for assessing shrinkage rate and shrink\/contraction force.<\/li>\n
  2. Measurement Setup<\/strong>: A temperature probe is positioned to monitor the sample area, providing precise temperature readings. The air oven automatically lowers to cover the sample area, facilitating accurate testing.<\/li>\n
  3. Sb\u011br dat<\/strong>: As the temperature rises, the maximum shrink force is measured, indicating when the shrinkage temperature has been reached. The process records the moment when this force decreases by approximately 15% to 30%, lifting the air oven and noting the time elapsed.<\/li>\n
  4. Shrinkage Ratio Assessment<\/strong>: During the testing phase, the shrinkage ratio is evaluated, offering vital insights into the film’s performance characteristics.<\/li>\n<\/ol>\n
