Stretch Film Consumption Comparison Calculator
Compare representative measured consumption after performance qualification. The planning period is the entered load count, not an assumed year.

First time using this calculator?
Replace the example values with figures from your supplier sheet or measurements. Choose the unit beside each value. Results update as you type; fix any highlighted field before using the result.
GSM means grams per square metre. Net weight excludes the core and other packaging. MOQ means the minimum order quantity. An optional field can stay blank unless the result you need depends on it.
Prices keep the selected currency; changing its label does not convert an exchange rate. Save or export the result after checking your inputs.
Film saved in entered period
Saved kg = (Old grams − New grams) × Loads ÷ 1,000
before = 350; after = 280; loads = 10000 → Film saved in entered period = 700 kg; Consumption reduction = 20 %Saved calculations stay in this browser. No account or cloud backup is created.

All other entered inputs stay fixed. Ranges are your scenarios, not statistical confidence or supplier performance predictions. This uses the same validated calculator engine.
The formula, made clear.
Compare representative measured consumption after performance qualification. The planning period is the entered load count, not an assumed year.
How to use this calculator
- 01
Confirm measured old grams per load, measured new grams per load, loads in explicit period.
- 02
Enter consistent units; zero means a confirmed absence of a charge or allowance.
- 03
Review the arithmetic, rounding and limitations before using the result in a purchasing decision.
A calculation you can check
70 g saved on 10,000 loads is 700 kg.
- Measured old grams per load
- 350 g
- Measured new grams per load
- 280 g
- Loads in explicit period
- 10000 units
before = 350; after = 280; loads = 10000 → Film saved in entered period = 700 kg; Consumption reduction = 20 %Check the displayed formula and units against your quotation. Use measured GSM, net weight and actual layout dimensions where available. Default densities are planning assumptions, not certified material properties. Calculated cost does not certify strength, compatibility or safe loading.
