Plastic Film & Flexible Packaging Test Calculators
Reduce five common sets of measured film and flexible-package test readings without a spreadsheet template, login, or equipment quote. These tools check arithmetic; your current method, laboratory SOP, and product specification still govern the test.
Five independent test records
Turn measured force, motion, light, and impact observations into reviewable results.
- 01What stress and elongation correspond to this thin-film tensile specimen?
Reduce thin plastic film tensile force, width, thickness, gauge length, and extension to tensile strength and elongation at break.
- 02What static and kinetic COF correspond to the recorded sled and pulling forces?
Calculate static and kinetic coefficient of friction from plastic-film sled mass, initial peak force, and average sliding force.
- 03What normalized peak and average seal strengths correspond to this peel specimen?
Normalize maximum and average flexible-package peel force to N/mm and the common N/15 mm reporting basis.
- 04What corrected haze and total transmittance follow from these four instrument readings?
Calculate corrected haze and total luminous transmittance from four integrating-sphere photometric readings.
- 05What 50% failure mass follows from five equal successive specimen groups?
Check five-level successive-group dart-impact arithmetic for the estimated plastic-film mass at 50% failure.
Keep the complete test basis
Record the exact material and lot, thickness and direction, conditioning, specimen preparation, apparatus and calibration, method revision, test settings, raw observations, invalid specimens, failure mode, replicate results, and acceptance specification. A correct calculation cannot repair an unrepresentative specimen or an invalid test.
