Shrink Film Size Calculator Online

Show Your Love:

Have you ever wondered how to size shrink film for your packaging needs correctly? It can be quite a conundrum. Fear not; we have the perfect solution for you – the Shrink Film Size Calculator. A simple yet powerful tool designed to eliminate the guesswork involved in shrink film sizing.


Shrink film is a material made up of polymer plastic film. When heat is applied, it shrinks tightly over the object it covers. Precise sizing of this film is crucial for effective packaging. Enter the Shrink Film Size Calculator. This calculator is an innovative tool that uses an object’s dimensions and the film’s shrinkage ratio to calculate the shrink film’s required size.

Detailed Explanation of the Calculator’s Working

The Calculator operates by considering the length, width, and height of the object you intend to wrap. It also considers the shrinkage ratio of the film. The shrinkage ratio is a percentage that indicates how much the film will shrink when heated. The calculator uses these inputs to determine the exact size of the shrink film required.

Formula & Variable Description

The formula behind the Shrink Film Size Calculator is quite simple. It first calculates the total surface area of the object using this equation: Surface Area = 2 * (Length * Width + Length * Height + Width * Height). It then considers the shrinkage ratio of the film, and finally, calculates the required film size using Required Film Size = Surface Area * (1 + (Shrinkage Ratio / 100)).


Let’s consider an example. Assume you have an object with dimensions 10 cm (Length), 5 cm (Width), and 2 cm (Height), and you’re using a shrink film with a shrinkage ratio of 50%. The Calculator takes these inputs and returns a precise measurement of the shrink film you’ll need.

Packaging Industry: This calculator is a game-changer in the packaging industry. It ensures that businesses use the right amount of shrink film, minimizing waste and cost.

Manufacturing: Manufacturing units dealing with packaged goods can use this tool to ensure their products are securely and neatly wrapped.


Can the calculator be used for any shape of objects?

The calculator works best with rectangular prisms (box-shaped objects). For irregular shapes, it might provide an approximation.


In conclusion, the Shrink Film Size Calculator is a revolutionizing tool designed to simplify and optimize shrink film sizing. Its ease of use and practical applications make it an indispensable tool in packaging and manufacturing industries.
