No. 1, contrast sample 2, contrast sample 3；Laboratory sample 1, laboratory sample No. 2 numbers, laboratory sample No. 3 numbers in embodiment two,
Burst pressure test is carried out respectively, and experimental result is as follows:
Contrast sample 1, contrast sample 2, the burst pressure of contrast sample 3 are followed successively by 22atm, 21atm, 22atm；It is real
Test sample 1, laboratory sample 2, laboratory sample 3 burst pressure be followed successively by 25atm, 25atm, 26atm.
Experiment two: the sample of the plastic bag of same process production is chosen；Plastic bag contrast sample without constraint silk ribbon 4
No. 4, contrast sample 5, contrast sample 6；Laboratory sample 4, laboratory sample No. 5 numbers, laboratory sample No. 6 numbers in embodiment two,
Using identical spraying parameter, spray time, the parameters such as spraying concentration are all the same, test the content of dispersion of 6 samples, experiment knot
Fruit is as follows:
Contrast sample 4, contrast sample 5, contrast sample 6 content of dispersion be followed successively by 402 μ g, 430 μ g, 422 μ g；It is real
Test sample 4, laboratory sample 5, laboratory sample 6 content of dispersion be followed successively by 598 μ g, 609 μ g, 623 μ g.
It can be seen that embodiment two with same plastic capsule from above-mentioned experimental result, have higher quick-fried
Broken pressure, and more drugs can be adhered to.The experimental result of the sample of other embodiments also advantage all having the same, herein no longer
It repeats.
