Stretch film is a valuable tool for protecting and securing items, but if you don’t know how much stretch film is needed, you can end up with too little or too much. Here are some tips on how to accurately measure the weight of your stretch film so that you always have enough to get the job done right! So whether you’re preparing a shipment or just storing items safely with extra protection, following these simple steps will help ensure that you always have enough stretch film on hand!

Definition of PE stretch film

PE stretch film (Polyethylene) is a highly elastic plastic film that is used to wrap, bundle, and secure products or items. PE stretch films come in two distinct varieties: cast stretch films and blown films. Cast stretch films are made using the extrusion process, where molten polyethylene resin is passed through a slit die, forming a thin and uniform web. Blown film are created by expanding hot air into the molten resin, forming bubbles that become multi-layered films as they expand. In both cases, the end product is a strong yet flexible material capable of providing excellent protection for products during transit and storage.

Purpose of calculating stretch film weight

The purpose of calculating stretch film weight is to determine the amount of hand stretch film that is required for a given machine application, pallet load, or other specific jobs, such as wrapping pallet loads. The calculation takes into account the size and shape of the item or items being wrapped, as well as environmental factors such as temperature and humidity. Knowing the weight of the stretch film roll helps to ensure that enough product is used to securely contain the items while not wasting excess materials. In addition, by accurately calculating the weight of the stretch film roll a user can also ensure that they are using a product with an appropriate degree of strength and flexibility for their particular application needs. Furthermore, if higher gloss levels are desired for aesthetic reasons, then selecting an appropriate type of hand stretch film which provides optimal gloss levels is critical in achieving this desired result. Ultimately, by accurately calculating the weight of a roll of stretch film a user can be fully confident that they have selected an appropriate material for securing their products during transportation or storage.


Calculating Stretch Film Weight

A. Gather necessary materials

  1. Stretch Film: To accurately calculate the weight of the stretch film, you’ll need the right type and quality of the film. The ideal stretch film should have a high level of cling, puncture resistance, and stretchability for any given application. Look for films that are made from polyethylene or other materials specifically designed for stretch wrapping.
  2. Ruler: You’ll also need a ruler to properly measure the length of the wrap. Measuring out the exact dimensions of each load allows you to determine how much total film will be needed. For best results, choose a ruler with precise measurements marked in both inches and centimeters.
  3. Scale: To get an accurate reading of the weight of your stretch film, you’ll need a reliable scale that can accommodate different types and sizes of loads. It’s important to use consistent measurements when weighing your items so that you can compare apples to apples when it comes to calculating costs and inventory levels over time. Choose a scale with a large-capacity platform that can handle heavy objects as well as light ones like plastic films. Try to find models with digital readouts for increased accuracy and ease of use when calculating weights.

B. Calculate the length of the stretch film

Step 1. Measure the length of the stretch film using a ruler, ensuring that precise and accurate measurement is taken.

Step 2. Record the length in a detailed and precise manner, noting any pertinent facts or measurements that may affect this length calculation, such as the thickness of the film or any wrinkles present. Additionally, expand on the recorded measurement by recording it 50% longer than usual to allow for an appropriate margin of error in future calculations.

C. Calculate the width of the stretch film

Step 1. Measure the width of the stretch film using a ruler and record the measurement in inches or millimeters

Step 2. Multiply the recorded width by 1.5 to calculate the stretched width of the stretch film. This will account for any additional material that may be needed to cover the package when stretched around it, to ensure that it is sufficiently secured.

D. Multiply the length and width of the stretch film

Step 1. Calculate the area of the stretch film by multiplying the length and width of the stretch film. The length of the stretch film is 20 inches, while the width of it is 18 inches. Thus, when we multiply these two values, we get a result of 360 inches squared (in2).

Step 2. Record the area calculated as 360 in2. This area encompasses all of the space occupied by this particular roll of stretch film; it is greater than a regular-sized sheet of paper and its dimensions are enough to cover many pieces of small objects very effectively due to the highly elastic structure that allows it to conform to any shape or size. Additionally, when stretched out properly, this type of product can cover large objects securely and efficiently with a tight grip that does not allow for any slipping or movement during storage or transportation. It also has excellent puncture strength and resistance against tears and abrasions which makes it perfect for protecting fragile items from damage due to external factors such as dirt, dust, moisture, and other elements.

E. Place the stretch film on a scale

Step 1. Carefully place the roll of stretch film onto the scale platform, ensuring that it is centered and evenly distributed. Make sure to take care when handling the roll of stretch film as excessive force can cause it to tear too easily.

Step 2. Once the stretch film is in place on the scale, take a moment to make sure that it is properly positioned and then record the weight on the display screen. Take note of exactly how much stretch film there is and mark down its weight in accurate detail so that you have a reference for later use. Be sure to include other pertinent information like manufacturing date or batch number if applicable for this particular roll of stretch film.

F. Multiply the area and weight of the stretch film

Step 1. Multiply the area of the stretch film by its weight to calculate the total weight of the stretch film. The area of the stretch film can be measured in square feet or meters, while its weight is typically in pounds or kilograms. By multiplying these two values, the total weight of the stretch film can be calculated

Step 2. To determine the total weight of a given stretch film, multiply its area by its specific gravity and then by its density. Specific gravity is a measure of how much heavier a material is than water, while density measures how many cells are contained in a certain volume of space. Taking into account these factors will yield an accurate calculation of the total weight of a given stretch film product. Furthermore, it is important to consider that certain factors such as width and thickness can also affect the total weight, so making sure to include these factors in any calculations is essential for obtaining an accurate result.


In conclusion, calculating the weight of polyethylene stretch film is an essential step to ensure that it meets the requirements for any application. With this guide, users can be certain that their polyethylene stretch film will be at the correct weight and meet all specifications for whatever purpose it is intended for.
