Coating film hardness: The hardness of the coating film on the outer surface of the cream bottle shall not be less than H pencil hardness. Adhesion: The adhesion of the coating film is not less than level 1. The surface decoration pattern is complete and clear. Low temperature resistance:
——20℃, after 24 hours, there should be no leakage, no deformation, no cracking, no cracks or obvious discoloration in the coating film and surface decoration pattern, and the spray performance meets the requirements. High temperature resistance: 50℃, after 24 hours, there should be no leakage, no deformation, no cracking, no cracks or obvious discoloration in the coating film and surface decoration pattern, and the spray performance meets the requirements. Sealing performance: After sealing performance test, no liquid leakage occurs. Drop test: When the vacuum bottle is filled with contents, it should be dropped freely once, and it should not leak or break without affecting its use. Spray performance: The vacuum bottle should spray out liquid within 10 times of pressing. The average single spray volume should be within the range of ±15% of the standard discharge volume. The single standard discharge volume shall be agreed upon by both parties. Vacuum pump suction: When the vacuum bottle is not filled with contents, press the vacuum pump directly, and the piston can move to the top of the vacuum bottle.
