Double Bubble

The Double Bubble film process is one of three technologies used to produce bi-axially orientated film. This technology is characterized by simultaneous stretching in the machine (MD) and transverse (TD) direction, resulting in orientation similar to the conventional Tenter process. The Double Bubble process also enables a balanced stretching of the film, which results in the same shrinkage in both directions (MD and TD).

Primarily used to produce high shrink film, the Double Bubble process also manufactures overwrap film used in applications such as tobacco film and wrapping for CDs.
