Halogen egg food composite film packaging composite fastness / peeling strength test method

Halogen egg food composite film packaging composite fastness / peeling strength test method stripping strength is to detect the composite fastness between the composite film layer and layer of food packaging, is to evaluate whether the composite film material is easy to layer one of the important basis.
Composite film material by the advantages of the single-layer film composite together, can give full play to the strengths of each film, to achieve complementary effects, so that the formation of composite film barrier performance, physical and mechanical properties and other properties have been greatly improved, and the composite fastness between the layers is an important factor affecting the role of strength.
If the composite fastness is low, it is very easy to separate between layers in the use of composite film, which not only reduces the physical and mechanical properties of packaging materials, such as barrier and impact resistance, but also affects the product image of the packaged contents, so it is of great significance to strengthen the monitoring of composite film composite fastness.
here, we take the halogen egg food compound film packaging as an example, for you to introduce the specific test methods and test instruments!At present, the domestic method standards for packaging with composite film peeling strength are GB 8808-88 "soft composite plastic material peeling test method."
test instrument recommends testing the peeling strength of the test using the XLW (EC) intelligent electronic pull test machine developed and produced by Labthink Languang.
the test process is as follows: (1) using a sampler along the aluminum-plastic composite film horizontal, vertical, respectively, 15 mm wide, 200 mm long samples each 5.
(2) at one end of the test, manually pre-peel 50 mm in the direction of length.
(3) clamps the two ends of the peeling part of the sample with the upper and lower fixtures of the equipment respectively, so that the long axis direction of the sample is re-matched with the center line of the two fixtures.
(4) to set test parameters such as test speed and width of the test.
(5) click on the test start option, the test starts, the device automatically tests the force values during sample stripping, and reports thetest results.
