ENGLISH??

One of the challenges of living here is buying groceries and such that are made in a foreign country. We bought a box of plastic wrap, but it was a foreign brand. Here are the instructions on the box: "Please press designation postition, open box the cover pulls up the length needed. To compress tightly a cover, cover cling film to side along the box last the teeth of a saw tears off. The usage pleases cover a cover behind." I'd love to know what nationality translated that to English. Can anyone tell me what that means??? By the way, the teeth do NOT cut the film AT ALL!!! We use scissors.
