Cling film cannot replace stretch film. Some of the characteristics of stretch film are that the cling film does not have. Although the cling film has a certain tensile force, it is not as strong as the stretch film; The cling film itself is sticky, which can not only attach to the wrapped object, but also stick to itself. The stretch film cannot adhere to itself. What's more, the stretch film has compression and fixation, which is not possessed by the cling film.

In addition, the properties of stretch film and cling film are also different: the former is the first to use PVC as the base material and DOA as the plasticizer in China, while the latter is usually made of ethylene as the masterbatch.

Although they look very similar, they actually have their own characteristics in terms of performance. Therefore, in some aspects, the cling film has no function of stretch film.
