Plastic cap is a very important part of the Cosmetic Packaging;When we choose a cosmetic tube,we also need to pay attention to the cosmetic cap,otherwise,leakage and some other issues may happen.
What are the caps mainly used on cosmetic packaging?
1,screw on cap
2,flip cap
3,needle nozzle nose cap/bullet cap
4,doctor cap
5,hex cap
6,bamboo cap
When we choose above caps,the most important thing is to ensure there is no leakage after cap screwed on tube.Besides,if we use a flip top cap,we need to test the butterfly part and open the flips many times to ensure the quality of the butterfly part is good and can use at least 200 times
How to know the caps and tubes matches well and no leakage?
1,If the tube tail is sealed,put the cap on the tube and press the tube body,if no air come out from tube which means the there will be no leakage after filling
2,If the tube is end open,screw the cap on the tube and check if there is a indentation on the foil seal or tube mouth.If yes,the tightness is good
We hope it will be helpful to you.If any more questions,welcome to ask our sales for help.
