Thermoformed cups: evaluate top load and clarity on the same cup

Thermoforming note

A cup may look clear but lose strength during stacking, filling or lidding. Sheet thickness distribution, heating, plug action and resin behaviour all affect the sidewall and base that finally carry the load.

We compare cups made with the same mould, forming conditions and nominal sheet thickness. Haze, gloss and visual appearance are reviewed together with cup weight, wall distribution, top-load curve and the mode of collapse.

Send cups from the same forming run

Provide trial and control cups, the sheet structure and gauge, forming temperatures, cup weight, top-load method and the customer's visual reference. If failure occurs during filling or transport rather than in a laboratory test, describe that operation as well.
