Vented caps, available from Caps and Closures , are designed to allow air to be released from inside the cap, relieving pressure and preventing the cap from popping off.
Vented cap closures prevent container distortion due to changes in temperature, product off-gassing and dispensing.
Using a vented cap prevents panelling which can occur when packages are filled with hot material, sealed and the contents cools and shrinks creating a vacuum.
The vented cap also can be used to vent internal build up of gasses.
Applications include household products, hair and skin care, cosmetic and protective applications, medical, automotive and chemical products.
Caps and Closures’ vented caps are available in 28mm and 38mm and can be matched to any specific colour.
