Plastic Film Lab Turns Blown-Film Math Into Shop-Floor Tools
A free browser-based calculator suite for film gauge, gram weight, extrusion output, roll length, bubble geometry, gussets, and dart impact.
Field notes
The page separates film-construction choices from measurements, including folded or tubular samples versus single-sheet inputs, and labels results by production context such as mil, grams, lb/hr, feet, and ratio. Its gusset module interprets notation like 48 × 36, while the dart-impact section provides Start test, Undo last, and Pass/Fail controls for a 20-impact sequence. A footer warning tells users to confirm critical production targets against plant-approved specifications and methods.
