Industries that use polyethylene bags
The characteristics of polyethylene bags make them one of the most widely used products in various industries. Learn about the industries that use polyethylene bags and the different applications that can make their processes easier.
Characteristics of transparent polyethylene bags
In addition to the characteristics mentioned earlier about polyethylene bags, other beneficial features for companies that use them can be listed. Here are their main properties:

What are polyethylene bags?
Polyethylene bags are bags made of high-density polyethylene (HDPE) or low-density polyethylene (LDPE) plastic. Either of these two raw materials provides them with characteristics such as elongation, tension, and breaking point in relation to their measurements and gauges.
These widely used bags not only differ in terms of their attributes depending on their manufacture but can also vary in terms of costs, versatility, and durability due to the type of material they are made from.
Biodegradable plastic bags
Technological innovations have allowed our plastic and polyethylene bags, in addition to being highly resistant and lightweight, to also be designed to reduce waste generation, as they have properties that enable them to degrade in the environment at a faster rate.
"The difference between high-density polyethylene (HDPE) and low-density polyethylene (LDPE) bags"
Different types of polyethylene bags can be obtained, classified according to the type of polyethylene with which they were manufactured.
The main difference lies in their molecular structures, as high-density polyethylene is manufactured through an addition process where different units of ethylene are added resulting in a higher molecular density. This allows high-density polyethylene to be more rigid and resistant.
On the other hand, low-density polyethylene will be composed of branched structures of ethylene, which gives it the characteristic of greater flexibility and transparency compared to high-density polyethylene.
How to calculate the weight of a polyethylene bag?
Calculating the weight of a polyethylene bag may seem complicated at first, but it’s quite straightforward once you understand the basic concepts. The first thing to know is that the weight of a polyethylene bag depends on three main factors: the dimensions of the bag (height, width, and, in some cases, thickness), the density of the material (polyethylene, which may vary slightly depending on the type), and the formula that relates these variables.
Here’s a practical formula for calculating the weight of a polyethylene bag:
- Bag dimensions: You’ll need to know the dimensions of the bag in meters (m) or centimeters (cm). If the bag is a rectangle, it will be the length and width. If it has a bottom or is of another type, it may be a bit more complex, and you’ll need to calculate the total area of material used.
- Material thickness: The thickness of the bag, usually given in microns (one micron is equal to 0.000001 meters or 0.001 millimeters). This data is crucial because the greater the thickness, the greater the weight of the bag.
- Polyethylene density: The density of low-density polyethylene (LDPE) is typically around 0.92 g/cm³, while that of high-density polyethylene (HDPE) is approximately 0.96 g/cm³. This density tells you how much a specific volume of the material weighs.
- Calculation: First, calculate the volume of the bag by multiplying the area by the thickness (remember to convert everything to the same unit, preferably meters or centimeters). Then, multiply this volume by the density of the material to obtain the weight.
The general formula would be:
Weight = Width × Length × Thickness × Density
Where the width and length are in meters (m), the thickness in meters (m) (remember to convert from microns to meters), and the density in grams per cubic centimeter (g/cm³), although you’ll need to adjust the units to match.
What is polyethylene used for?
Polyethylene is primarily used in the manufacturing of packaging, containers, and construction products due to its strength and flexibility. It is also essential in agriculture and in the production of toys and automotive components, thanks to its durability and lightweight nature.
Is it easy to recycle polyethylene?
Yes, polyethylene is one of the easiest plastics to recycle, thanks to its ability to be reprocessed multiple times without losing its properties, which allows it to be used in the creation of new products, reducing environmental impact.
How resistant is polyethylene?
Polyethylene is highly resistant to moisture, chemicals, and physical wear, making it ideal for applications that require durability, such as packaging, construction products, and more, with its resistance varying depending on the type (high or low density).
Most common measurements of transparent plastic bags
The most common measurements of plastic or polyethylene bags vary depending on their use, but generally include sizes such as 20×30 cm, 30×40 cm, and 40×50 cm for domestic and commercial applications.
In the industry, dimensions can be larger, adapting to specific needs such as storage or transportation of large volumes of products.
Trash bags are usually larger, ranging in size from 50×70 cm to 80×110 cm, depending on their capacity and intended use.
