Shrink sleeve film cost

Inputs and displayed results

The calculator uses eight entered values: maximum container diameter in inches, finished sleeve height in inches, flat-film seam allowance in inches, vertical shrink as a percent, printed film price per 1,000 square inches, quantity, setup cost and seaming and application cost per sleeve. The three cost fields are your quote values, not rates supplied by the tool. Outputs are flat film width, cut height, film area per sleeve, film cost per sleeve and modeled finished cost per sleeve. Width and cut height display to three decimals, area and money to two. Cost math uses unrounded width, cut height and area before display rounding.

How flat width and cut height are built

Flat film width equals pi times maximum container diameter plus seam allowance. The diameter term gives circumference and the seam adds material for the flat-film join, so a larger diameter or seam increases width. Cut height equals finished sleeve height divided by the retained fraction after vertical shrink, where the retained fraction is one minus shrink percent divided by 100. This makes the starting cut longer than the finished height. Higher vertical shrink lowers the retained fraction and increases cut height.

Turning film area into film cost

Film area per sleeve is flat film width multiplied by cut height, a rectangular flat-film area for one sleeve before process allowances. Film cost per sleeve equals area multiplied by the entered film rate and divided by 1,000, because the rate is per 1,000 square inches. The rate is not a per-sleeve price. If the film rate is zero, film cost per sleeve is zero even when geometry is nonzero. Changing diameter, seam, finished height or shrink changes area and therefore film cost when a rate is entered.

Setup, application and the per-sleeve total

Modeled finished cost per sleeve adds film cost per sleeve, seaming and application cost per sleeve, and setup divided by quantity. Application is entered per sleeve, so it is added directly. Setup is an order-level amount, so dividing by quantity spreads it across the run. Increasing quantity lowers setup allocation per sleeve but does not change film area, film cost per sleeve or application per sleeve. Quantity must be at least one because setup is divided by it. The total is modeled from entered values, not a production quote.

Reading the outputs operationally

Flat film width is the flat-film width including seam, not finished circumference. Cut height is pre-shrink cut length, not finished sleeve height. Film area per sleeve is geometric flat-film area before slip clearance, web trim, waste, graphics distortion and film-specific shrink curves, which the model does not include. The modeled finished cost per sleeve helps compare entered quote scenarios and see how geometry and quantity move the arithmetic. Read it as a geometric price worksheet result, not a sleeve production quote or a statement that the sleeve will fit or perform in production.

Worked examples with entered quote values

In the starting scenario, diameter is 2.6 inches, finished height 4.5 inches, seam 0.25 inches, shrink 8 percent, quantity 1,000 and the three cost fields are zero. Flat film width is 8.418 inches, cut height 4.891 inches and film area per sleeve 41.18 square inches. Film cost per sleeve and modeled finished cost per sleeve display as $0.00 because entered cost values are zero. In the changed scenario, same geometry and quantity use entered film price $0.60 per 1,000 square inches, setup $100 and application $0.05 per sleeve. Film cost per sleeve displays $0.02, setup contributes $0.10 per sleeve and application $0.05 per sleeve, so modeled finished cost per sleeve displays $0.17. Unrounded film cost is about $0.0247 and unrounded total about $0.1747. These are synthetic entered quote values for illustration, not market rates or Teal quotes.

Edge case: high vertical shrink

Vertical shrink has a strong effect because cut height is divided by the retained fraction. At 95 percent shrink, the retained fraction is 0.05, so a 4.5 inch finished sleeve requires a cut height of 90 inches, 20 times the finished height. With 2.6 inch diameter and 0.25 inch seam, flat width remains 8.418 inches, but area rises to 757.63 square inches. At an entered film rate of $0.60 per 1,000 square inches, film cost per sleeve would be about $0.45 before application and setup allocation. The shrink entry needs converter review for the actual film.

Assumptions and limits to keep in view

The model uses one maximum container diameter and one finished sleeve height. It does not add slip clearance, web trim, waste, graphics distortion or film-specific shrink curves, which require converter review. It is a geometric price worksheet, not a sleeve production quote. It does not establish fit, safe loading, certification, legal status or production guarantees. Use outputs to understand how entered dimensions, shrink, film rate, quantity, setup and application interact, then confirm actual sleeve construction and film behavior with the converter.
