1.Introduction of\u00a0FSR-01\u00a0Shrink Force<\/a>\u00a0and Ratio\u00a0Testador|\u3001Teste de pl\u00e1sticos<\/a>\u00a0\u00a0<\/strong><\/h2>\n<\/div>\n

The FSR-01 Shrink Force and\u00a0Ratio Tester<\/a>\u00a0serves the purpose of measuring both the shrinking forces and shrinkage ratio of heat shrinkable films. These films are typically created through extrusion and stretching (hot drawing) during their manufacturing process, retaining this stretched state even after cooling.<\/p>\n

Shrinkage is determined by immersing the film in an oil bath at a selected temperature. The shrinkage in the machine and transverse directions is determined as a function of time.
\nThe shrinkage tension determination is based on\u00a0DIN 53369<\/strong>. The test specimen is connected to a load cell, briefly placed in a hot oven and then cooled to room temperature. The forces generated during the shrinkage of the material are recorded.
\nShrink films are used as outer packaging for a wide variety of packaging. When heat is applied to the film, it shrinks and wraps tightly around the covered object. The shrinkage of the film is based on the relaxation of the orientation stresses introduced during the film production process. Stress relaxation allows for a good closure of the package.<\/p>\n

2.Why do you need a Shrink Force and Ratio\u00a0Testador|\u3001F\u00e1brica de testes de pl\u00e1sticos<\/a>?<\/strong><\/h2>\n

When the heat shrinkable film is reheated to the temperature at which the initial stress was introduced and subsequently fixed during its production, this stress is released, causing the film to contract or “shrink back.” Depending on the specific manufacturing treatment applied, the film can be categorized as either biaxially oriented (stretched in two directions) or uniaxially oriented (stretched in one direction).<\/p>\n

1. A well-insulated air oven is heated to the set temperature. The two samples are placed separately on two test stations, for shrinkage rate and shrink\/contraction force testing.<\/p>\n

2. A temperature probe is located to measuring area, to give result as reference temp. The air oven is driven down automatically to cover the sample area. The force and shrink rate are to be measured and the shrinkage temperature is reached when the maximum shrinking force is attained.<\/p>\n

3. When this force has decreased by around 15%~30%, the air oven is lifted and time is recorded.<\/p>\n

4. The assessment of shrinkage ratio is performed at the mean time<\/p>\n
