Apart from the tool design, webbing usually occurs when you cannot sufficiently control the flow of the heated sheet as the tool is raised into the sheet. When the vacuum is applied it will always suck down first the part of the sheet that has the least resistance.

If you were to imagine draping a cloth over your tool, rather than a plastic sheet, then the resulting folds and pleats would identify the possible problem areas that your plastic sheet will encounter during the forming process.
