Paste the test adhesive tape on the surface of the aluminum layer (no bubbles are required between the adhesive tape and the aluminum layer surface), and roll back and forth on the adhesive tape roller machine once. Leave it for 5min~10min, clamp the sample on the A plate, fix the exposed adhesive tape on the B plate (see Figure 1), and then turn on the machine. The A plate peels off the adhesive tape at a speed of 0.6m/min~1.0m/min. 5.4.8.4 Result expression
Cover the peeled part with a translucent millimeter grid paper with a width of 20mm. Count the number of grids A occupied by the aluminum spray surface and the number of grids A2 occupied by the peeled aluminum layer or coating. Calculate according to formula (1): 5

1A disk: d=170mm, W=55mm; 2—B disk: d=65mm, W=55mm3—sample; 4—ink layer; 5—adhesive tape; 6—pressing sheet; 7-rotation direction of A disk; 8—rotation direction of B disk. Note: The pressure between A and B disks is 100N. Figure 1 Schematic diagram of disk peeling test machine
Surface adhesion of aluminum layer = A,/(A,+4,)×100% In the formula:
A, the number of grids of aluminum spraying surface;
A2 the number of grids of aluminum layer or coating removed;
The test result is expressed in percentage (%). Keep one decimal point. 5.4.9 Single sheet flatness
Under laboratory conditions of (23±1)℃ and (50±2)%, take a 300mm×300mm sample, place the sample with the aluminum layer facing upwards on two flat glass plates, and after 1 hour, use a ruler to measure the highest point of the sample curling. 5.4.10 Moisture content shall be determined in accordance with the provisions of GB/T462. 5.4.11 Heat resistance
Place a 50mm×150mm standard sample between the upper and lower pressure heads of the heat sealer, adjust the instrument pressure to 98kPa, and the pressing time to 0.5s. Start from 100℃, increase 5℃ each time, and conduct a heat resistance test on the aluminum layer surface of the sample. The surface coating is considered to meet the requirements when there is no obvious discoloration. The highest temperature that the surface coating can withstand is the heat resistance temperature. 5.4.12 Static friction coefficient and dynamic friction coefficient are measured by rubbing the aluminum surface of the aluminum-plated paper against the bottom surface in accordance with the provisions of CB/T10006. 5.5 Holographic technical indicators
5.5.1 Signal-to-noise ratio
Measured in accordance with the provisions of GB/T17000.
5.5.2 Diffraction efficiency
Measured in accordance with the provisions of GB/T17000.
5.6 Hygiene indicators
Measured in accordance with the provisions of CB/T5009.78. 6
