Appendix B
(Appendix to the standard)
Test method for sealing strength of composite materials
B1 Definition
The maximum load of a heat-sealed sample of specified width at break. B2 Instrument
B2.1 Testing machine: The reading error should be within ±1%. B2.2 Vernier caliper: accuracy 0.02mm.
B2.32 Ruler: accuracy 1mm.
B3 Sample
B3.1 Sampling method
B3.1.1 Take samples from the coiled material along the coil forming direction for butt sealing inspection, and take samples perpendicular to the forming direction for lap sealing inspection. When checking the lap strength, it is allowed to seal the protective seal that meets the use conditions at the same time. B3.1.2 For materials that have been sealed longitudinally and are supplied in the form of semi-finished containers, take samples in the direction parallel to the longitudinal seam for butt sealing inspection, and take samples in the direction perpendicular to the longitudinal seam with the longitudinal seam as the center point, and take the existing longitudinal seam as the lap seal for inspection. B3.1.3 The sealing method can be determined by each manufacturer. B3.2 Sample size
The sample is rectangular: length (100±1) mm, width (15±0.1) mm. When it is not possible to obtain a sample with an unfolded length of 100±1 mm, it is allowed to use adhesive tape to bond the same material from both ends to achieve the specified size of the sample. B3.3 Number of samples
GB18192—2000
Sampling shall not be less than 10 each time, and the test result shall be the average value of 10 samples as the result, expressed as N/15mm, and take 3 significant figures. B4 Inspection steps
The sample shall be conditioned for 4 hours at a temperature of 23℃±2C. The state-adjusted sample is unfolded 180° with the sealing part as the center line. The two ends of the sample are clamped on the fixture of the test machine. The longitudinal axis of the sample should coincide with the upper and lower center lines, and the tightness should be appropriate to prevent the sample from slipping or breaking in the fixture. The distance between the fixtures is 50mm, the test speed is 300mm/min±20mm/min, and the maximum load when the sample breaks is read. If the sample breaks in the fixture, the sample is invalid and another sample is taken to make up. Appendix C
(Appendix of Standard Push)
Test method for adhesion between composite plastic film and paper C1 For materials supplied in roll form, cut a 1m long full-width sample from the sample and place the sample flat on the table with the inner PE layer facing up. Starting from the corner of the sample, use a knife to peel off between the paper and the composite PE layer, and slowly tear off a strip with a width of 30mm~50mm, passing through the entire width. Visually inspect the exposed composite layer surface. Determine the percentage of the area on the plastic surface that has paper fibers attached to it. Repeat this step diagonally in the opposite direction.
Continue to use a knife to divide the entire sample into several groups of 80 mm width. Manually peel each group slowly from the machine direction and the reverse direction, and visually inspect the exposed composite surface of each group.
Determine the percentage of the area on the plastic surface that has paper fibers attached to it. The worse result shall prevail. C2 Materials supplied in the form of semi-finished products are first cut along the longitudinal seam, and the overlapping part of the longitudinal seam is removed. The sample is cut into the largest rectangle. Starting from the corner of the sample, use a knife to peel between the paper and the composite PE layer, and slowly tear off the composite layer. Visually inspect the exposed composite surface.
Determine the percentage of the area on the plastic surface that has paper fibers attached to it. Repeat 3 times. The worse result shall prevail. 413
