87 regulations, the biodegradability of paper bags should comply with the regulations.
Pre-treatment
Measure the two ends of the covered measuring part once, take the maximum deviation steel ruler,
measure the overprint part with a scale of 0.5 mⅡ steel ruler, and calculate the result based on the maximum overprint error. 6.3 Determination and calculation of bag thickness
6.3.1 Plastic thickness measurement is carried out in accordance with GB/T 6672-2001. Measure 4 points on each bag and take the arithmetic mean. The result is rounded to 0.001 mm. 6.4 Printing peeling rate 6.4.1 Cut the sample from the part with more printing on the bag, with the printed side facing upwards. Use transparent tape to fix the four sides of the sample on the table to expose the test part: 100 mm×100 mm. Do not touch the measured part with your hands during the operation. Use an adhesive tape with a 180° peel strength of 6.5N/15min and 1.0N/15min. Take 15m and a length of 175mm, stick it on the remaining printed surface of the sample, fold it 180° at 75°, and roll it back and forth with a 1kg roller on the sticking part for 2 times. Then peel quickly by hand, and measure the stripping area and residual area of the ink with a 0.5mm ruler. Take two bags for testing, and calculate the average value. The result is rounded to 1%. 6.7.2 Printing stripping rate is calculated according to formula (1): Printing stripping rate (%) -
6.5 Sealing strength
6.5.1 Sealing strength is carried out according to Q3/1 2358--1998. Stripping area
Residual area
6.5.2 The sealing strength test speed of plastic bags is 300 mm/min±50 mm/min. 6.5.3 The sealing adhesion strength test speed of paper bags and paper-based bags is carried out according to GB/12914-1991. (1)
6.5.4 Take four test pieces from each sample for testing, and calculate the arithmetic average value. The result is rounded to 0.1N/15mm. When the medicine mouth is not broken but the material is broken, the sealing strength is measured by the material crack load. 6.6 Water leakage test
Put one-fifth of the bag into 23℃ + 2℃ clean water, keep it still for 1 minute, observe whether there are water drops on the bottom of the bag, and record the observed phenomenon. Use three bags to test, and the minimum value is the measurement result. 6.7 Lifting test
6.7.1 Test equipment: bag fatigue testing machine, shooting range 30mm:2mm, frequency 2Iz~3Hz. 6.7.2 Fill three-quarters of the bag with the mixture of the subject particles equivalent to twice the nominal content, and then hang it on the testing machine to observe whether the body and the handle are damaged. Use three bags to test, and the minimum value is the measurement result. 6.8 Drop test
Fill three-quarters of the bag with the actual contents or the granular mixture equivalent to the nominal contents, seal the bag mouth with adhesive tape, and drop it freely from a height of 500mm. The test floor is a smooth cement floor. Observe whether the bag is damaged. Use three bags to test, and take the smallest value as the cumulative value:

7.3.2 The appearance, size, originality and printing quality in the type inspection are carried out according to GB/T15289, and the sampling plan (mode A) LQ is 5.0. The other items are randomly sampled from the samples after the appearance and size inspection according to the number specified in 6.5.6.6, 6.7 and 6.8. The insufficient part is randomly sampled from the batch. Sufficient samples are randomly sampled from the batch for the degradation performance and hygienic performance tests. 7.3.3 The appearance, size, thickness and printing volume of the inspection shall be carried out in accordance with GB/T15482, and the sampling plan of the second level of inspection shall be adopted, with n=2, N=210, D,=7, n=12. The other items shall be randomly selected from the samples after the appearance and size inspection according to the quantity specified in 6.5, 6.6, 6.7 and 6.8, and the insufficient part shall be randomly selected from the supervision population. Sufficient samples shall be randomly selected from the supervision population for inspection of degradation performance and hygienic performance. The supervision and inspection department may determine the main sampling parameters in the standard or select other applicable standards according to the purpose of inspection. 7.4 Judgment rules
7.4.1 Judgment of qualified items
7.4.1.1 The inspection results of appearance, size and printing quality shall be judged individually in accordance with the provisions of 5.1.5.3 and 5.4. If they meet the provisions of the standard, the sample is judged to be qualified in terms of external specifications, size and printing quality, otherwise it is unqualified in terms of individual items. 7.4.1.2 The test results of thickness and physical and mechanical properties shall be judged individually according to the provisions of 5.2 and 5.5 respectively.
