Structural features of packaging cans
1. There are several unique sealing points between the packaging can body and the packaging lid to ensure no leakage of liquid.
2. The inner edge of the cover is equipped with a ring of reinforcement to ensure that the accumulated load is transferred to the reinforcement.
3. The bottom of the packaging can and the lid of the packaging can match each other to ensure stable accumulation during storage and transportation.
4. There is a tear circle on the lid of the packaging can to ensure that the lid will not be lifted when it falls during transportation.
5, Anti-counterfeiting, must tear the ring to open the cover, to ensure that the famous brand products are not counterfeit.
Q:How many seaming is the best for steel cans?
A:China usually has 5 or 7 floors, which is also called 2 or 3 floors in foreign countries.
Q:What is the commonly used air tightness test for steel cans?
A:Test method: the tested package is immersed in water and inflated to make the pressure inside the package reach the specified value. The pressure control method shall not affect the validity of the test, and the leakage shall be observed. Equivalent methods can also be used.
Q: What is steel cans sealant usually composed of?
A:Base materials, plasticizers, fillers, solvents and other auxiliaries.
Q:What tests do steel cans usually do?
A:Drop test, air-tight test, hydraulic test, stacking test, etc
Q: What is the applicable scope of steel cans?
A:In addition to the field of drug packaging, it can be used in other fields such as chemical industry, food, local goods, hardware, minerals, building materials, mechanical and electrical equipment, injury products, military explosives and national defense industry.
