How To Calculate PE Film Weight Accurately Guide

PE (Polyethylene) film is a popular material widely used in packaging, wrapping and many other applications. Calculating the exact weight of PE film is very important in many aspects, from production to transportation and storage. This article will guide you on how to calculate the weight of PE film  easily and accurately.

Understanding Units of Measure

gsm (gram per square meter): This is the most common unit of measurement for PE film weight . It indicates the weight of 1 square meter of PE film.

kg/m2 (kilogram per square meter): This unit is similar to gsm, except the unit of measurement is kilogram.

Instructions how to calculate the exact weight of PE film

The most common formula for calculating PE film weight is:

PE film weight  = Length x Width x Thickness x Specific gravity

In there:

Length: Length dimension of PE film (unit cm or m)

Width: Width size of PE film (unit cm or m)

Thickness: Thickness of PE film (unit cm or mm)

Density: Density of PE film (usually 0.95 g/cm³)

For example:

Suppose you have a roll of PE film with a length of 100 m, a width of 50 cm and a thickness of 0.05 mm. Applying the above formula, we can calculate the weight of the PE film roll as follows:

Weight = 100 m x 0.5 m x 0.0005 m x 0.95 g/cm³ = 2.375 kg

Note:

PE film thickness:  The weight of PE film depends on its thickness. Thicker PE film will have higher specific gravity.

PE plastic types:  There are many different types of PE plastic, each with a different specific gravity.

Environmental conditions:  Temperature and humidity can affect the weight of PE film.

Alternatively, you can also use online calculators to quickly and easily calculate the weight of your PE film. These tools usually require you to enter parameters such as the length, width, thickness and density of your PE film, and then automatically calculate the weight for you.

Why do we need to calculate the weight of PE film?

Calculating the weight of PE film brings many benefits:

Manage packaging costs effectively:  Identify the exact materials needed, saving costs.

Reasonable production planning:  Ensure supply, avoid surplus or shortage.

Waste reduction:  Use PE film economically and protect the environment.

Calculate accurate shipping weight:  Ensure safety of goods and optimize shipping costs.

Characteristics of PE stretch film

Before learning the formula for calculating the weight of Pe membrane, let's take a look at some of its outstanding features:

Color: Normally the product will be clear white, black or opaque white.

Size: Many different sizes depending on customer needs

Material: Made from the main ingredient of polyethylene plastic particles that are melted and pressed into film.

Water resistance, anti-UV: When exposed to direct sunlight, the film has the effect of blocking harmful UV rays and diffusing light through the film more evenly, preventing dust, rain, wind, and other environmental impacts.

Adhesion: Most commonly found in food wrap and packaging film, the film's adhesion makes the product convenient and secure to use.

In short, the weight of PE film is an important factor that needs to be calculated accurately before use. By applying a simple formula based on the size and thickness of the film, you can easily determine the required volume for the intended use.
