5.1 Appearance quality inspection is carried out by visual inspection under natural light. 5.2 The length and width deviation of the bag are inspected with a ruler or tape measure with a scale of 1mm. Each measurement takes a data from both ends and the middle, and calculates the average of the three data, accurate to one decimal place. 5.3 The thickness deviation of the bag is inspected in accordance with the provisions of GB/T6672-1986. 5.4 The width deviation of the heat-sealed seam of the bag body and the width deviation of the heat-sealed seam of the bag mouth are measured and tested with a vernier caliper with an accuracy of 0.1mm. 5 data are measured for each bag and the average value is calculated with an accuracy of one decimal place. 5.5 The position deviation of the flap is measured and tested with a ruler with a scale of 1mm. 5.6 The oxygen permeability test is carried out in accordance with the provisions of GB/T1038-2000. The tensile strength test is carried out in accordance with the provisions of GB/T13022--1991. 5.7
The sample size is (150±2) mm×(15±0.5) mm, and the test speed is (100±20) mm/min. 5.8 The test of elongation at break is carried out in accordance with the provisions of GB/T13022-1991. The sample size is (150±2) mm×(15±0.5) mm, the test speed is (100±20) mm/min, and the sample gauge length is 50mm. 5.9 The peeling strength test of the composite film shall be carried out in accordance with the provisions of Method A in GB/T8808-1988. All samples shall be deemed qualified when they cannot be peeled off. 5.10 The inspection of the heat seal strength of the bag body shall be carried out in accordance with the provisions of QB/T2358-1998. 5.11 The inspection of the heat seal strength between the bag opening and the bag body shall be carried out in accordance with the provisions of QB/T2358-1998 except for the sampling position and the number of samples. Sampling position and sampling number:
If the bag opening is 25mm or 51mm, the sampling position is as shown in Figure 1: 180
Heat seal seam of loading mouth
GB18454--2001
Take a sample every 60°, with a width of (15±0.5) mm, and take a total of six samples for one bag opening. If the bag opening is less than 25mm, the number of samples taken for each bag opening and the angle between each sample shall be based on the principle of taking as many samples as possible, but the width of the sample must be guaranteed to be (15±0.5) mm, and the samples should be evenly distributed along the circumference. During the inspection, the sample should be unfolded, with one end being the bottom edge of the bag opening and the other end being the composite film heat-sealed therewith, and they should be clamped on the two fixtures of the testing machine. 5.12 The light transmittance test shall be carried out in accordance with the provisions of GB/T2410-1988. 5.13 Pressure resistance test of bags

Inflated sterile bag
5.13.2 Make a small hole on the top cover of the test bag, insert the inflation nozzle and inflate the bag to the pressure holding pressure. 5.13.3 Use the leakage liquid smearing method to check all parts of the bag to see if there are bubbles. 5.13.4 Continue to increase the inflation pressure until the bag ruptures, and record the rupture pressure. Test at least 3 bags, and use the minimum rupture pressure as the basis for judgment.
5.14 Drop performance test of bags
5.14.1 Fill test bags of different capacities with water or materials similar to the actual contents and cover the lids. 5.14.2 Drop
Bags less than or equal to 25L: lift the filled bag to the height specified in Table 5 for free fall (the ground is cement or terrazzo, and there are no sharp foreign objects or sand on the surface), and visually check whether the bag is leaking or ruptured. 181

Bags greater than 25L: put the filled bag into the corresponding outer packaging, the inner wall of the outer packaging should be free of burrs and foreign objects, lift the outer packaging to the height specified in Table 5 for free fall (the ground is cement or terrazzo, and there are no sharp foreign objects or sand on the surface). Pour out the bag and visually check whether the bag is leaking or ruptured.
5.14.3 Test at least 3 bags. If one or more (including) items are unqualified, the inspection is deemed unqualified. 5.15 Lining material: The hygienic index inspection of the composite plastic film and the cover shall be carried out in accordance with the provisions of GB/T5009.60-1996 and GB/T13120-1996.
