Pouch Weight Calculator
Estimate pouch film weight from the production web, or use a simple front-and-back rectangle for an early flat-pouch estimate. Select the method that matches the information actually available.

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.
Help with web width
Measure the full width of the flat material from edge to edge, rather than the width of one finished pack. Choose the matching unit.
Use actual supplier or measured GSM when available.
Help with film gsm
GSM is the weight of one square metre of material, in grams. Find it on the supplier specification; use the complete laminate value for layered film.
Film weight per production unit
Production-web allocation includes material within the entered web and repeat. Zippers, valves and other separate components are excluded.
Film weight (g) = web width (m) × repeat (m) ÷ lanes × GSM
0.8 × 0.25 ÷ 2 × 80 = 8 gSaved calculations stay in this browser. No account or cloud backup is created.

How sensitive is this result to your assumptions?
Vary one input and inspect film weight per production unit
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.
The production-web method is preferred when actual web width, repeat and lane layout are known, because it allocates the film consumed by each unit. The flat-pouch method estimates material area from finished dimensions and the selected number of faces. It is a preliminary geometric estimate and can miss material folded into gussets, seal geometry or other features. Neither method automatically includes zippers, spouts, valves or other separate components.
How to use this calculator
- 01
Choose production-web allocation or a simple flat-pouch estimate.
- 02
Enter dimensions for the chosen method and complete-film GSM.
- 03
Compare the result with a finished sample weight or a verified production layout where accuracy matters.
A calculation you can check
The example estimates the film contribution to pouch mass using the selected geometry, with its method limitations kept separate from the numerical result.

0.8 × 0.25 ÷ 2 × 80 = 8 gCheck 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.
