1. Appearance: It is mainly based on visual inspection and in a well-lit environment, with normal vision, 20cm-30cm from the front of the eye for inspection.

2. Size: Use a ruler or a vernier caliper with an accuracy of 0.02 mm to measure the sample and record the value.

3. Weight: Weigh the sample with a scale with a division value of 0.1g and record the value.

4. Capacity: Weigh the sample on a scale with a division value of 0.1g, remove the gross weight of the bottle, inject tap water into the sample bottle to the full mouth, and record the value (if necessary, directly inject the paste or convert the density of water and paste) ).

5. Printing adhesion and hot stamping (silver) fastness:

(1): Use the 3M810 test tape to cover the printing and hot stamping (silver) parts, smooth them so that there is no air bubbles in the cover, and then quickly tear off. The printing parts are done 3 times in a row, and the hot stamping (silver) parts are done 2 times in a row.

(2) Wipe the printed area back and forth twice with gauze soaked in disinfected alcohol.

6. Clamshell performance: At room temperature, the clamshell can be opened and closed 200 times without breaking. The tightness and tightness are the same as before the clamshell.

7. Compatibility test of bottle caps: The bottle caps cooperate smoothly and are not slippery. The bottle and caps are divided into screw type and snap type, and the snap gap between the snap type bottle and the cap is ≤0.4mm; the screw type bottle and cap fit gap: 0.1 mm≤gap≤0.6mm.
