This is a packaging that two blister clamshell with insert card need to be sealled by High frequency sealling machine. It is very slap-up with tidy and nice margin, but high cost and low effeciency of production

Pls note 

1,the blister must be PVC or PETG material, Otherwise the two blister can not seal.

2,the quality of the edge depends on the quality of the mould
