What You'll Learn
HDPE plastic is the thickest available
HDPE, or High-Density Polyethylene, is a thermoplastic polymer produced from the monomer ethylene. It is a strong, stiff, durable, lightweight, and versatile plastic material that is easy to fabricate, bond, weld, and mould. It has a high strength-to-density ratio, impact strength, and chemical resistance, along with low water absorption. It is also abrasion-resistant, bacteria-resistant, and moisture-resistant.
Owing to its desirable properties, HDPE is used in a wide variety of applications. It is used in the production of plastic bottles, milk jugs, shampoo bottles, bleach bottles, detergent bottles, food storage containers, geomembranes, plastic lumber, chemical tanks, machined parts, industrial cutting boards, toys, pipes, films, plastic bags, and more. It is also used for cell liners in sanitary landfills, where large sheets of HDPE are welded to form a homogeneous chemical-resistant barrier to prevent the pollution of soil and groundwater.
HDPE is known to replace heavier materials, helping companies and individuals pursue sustainable and affordable manufacturing and project goals. It is also used in infrastructure expansion, including the deployment of pipes and cable insulation. HDPE is easily recyclable, helping keep non-biodegradable waste out of landfills and reducing plastic production.
The thickness of plastic is expressed in microns or "mils" (thousands of an inch). HDPE is the thickest plastic sheeting available, with thicknesses of 12 mil, 20 mil, 30 mil, 40 mil, 60 mil, 80 mil, and 100 mil. It is available in a wide variety of sizes and thicknesses and is formulated to last in both hot and cold climates. It is also UV-resistant and provides a projected installed lifespan of greater than 100 years when installed away from direct sunlight.

It is a form of high-density polyethylene
High-density polyethylene (HDPE) is a thermoplastic polymer produced from the monomer ethylene. It is also known as polythene or alkathene when used for HDPE pipes. HDPE is a popular choice for heavy-duty applications due to its longevity, strength, and protective qualities. It offers high impact strength, chemical resistance, and low water absorption.
HDPE is commonly used in the production of plastic bottles, cutting boards, and corrosion-resistant piping. It is also used in geomembranes, which are large sheets of HDPE welded together to form a homogeneous chemical-resistant barrier, preventing the pollution of soil and groundwater. HDPE is preferred in the pyrotechnics trade for mortars over steel or PVC tubes due to its durability and safety.
The density of HDPE ranges from 0.93 to 0.97 g/cm3, which is only marginally higher than low-density polyethylene (LDPE). However, HDPE has a linear structure with little branching, resulting in stronger intermolecular forces and tensile strength compared to LDPE. This structural difference gives HDPE a higher specific strength, making it an excellent choice for applications requiring high strength-to-density ratios.
HDPE is highly resistant to chemicals, UV rays, weathering, and corrosion. It is also BPA-free and recyclable, making it an environmentally friendly option. The physical properties of HDPE can vary depending on the molding process used during manufacturing, and it is known for its high malleability and rigidity. With a high melting point, HDPE remains rigid at very high temperatures and can be moulded efficiently for various applications.

It is used in heavy-duty applications
HDPE (High-Density Polyethylene) is an incredibly versatile material used in many applications due to its longevity, strength, and protective qualities. It is a thermoplastic polymer made from petroleum and is known for its high strength-to-density ratio. The thickness of HDPE plastic ranges from 30 mils (0.03 inches) to over 100 mils (0.1 inches), with each thickness providing different benefits. For instance, thicker HDPE provides higher protection against damage, chemical exposure, and other environmental factors.
One of the key advantages of HDPE is its durability. It resists breaking, wear and tear, and deterioration, making it a popular material for various car parts. HDPE is also UV-resistant, preventing deterioration when exposed to sunlight for extended periods. This quality, along with its strength and flexibility, makes it ideal for construction, landscaping, agriculture, and industrial operations.
HDPE's resistance to a wide range of chemicals is another reason for its popularity in heavy-duty applications. It is frequently used in environments exposed to corrosive elements, ensuring the protection of equipment and surfaces. Additionally, HDPE's low water absorption makes it suitable for projects involving water and moisture control.
The thickness and strength of HDPE plastic also make it suitable for specific applications requiring durability and flexibility. For example, HDPE is used in dog kennels as protection barriers to prevent dogs from fighting or pestering each other. The 60 mil variant is strong, easy to work with, and easy to clean, making it a perfect fit for this application.
In terms of temperature resistance, HDPE can withstand both hot and cold climates, making it suitable for a wide range of temperature applications. This quality, along with its overall durability, contributes to its longevity, reducing the need for frequent replacements and saving costs over time.

Thickness is measured in mils
The thickness of plastic is a critical factor in determining its suitability for various applications. While there are many different types of plastics, each with unique properties, the thickness of a plastic sheet or film is a key parameter that influences its performance and functionality. Thickness is measured in mils, which are thousandths of an inch. This unit of measurement provides a precise way to quantify the thickness of plastic, ensuring consistency and accuracy in the production and application of plastic materials.
The measurement of plastic thickness is not limited to a single method, and various techniques are employed depending on the specific requirements and characteristics of the plastic. One commonly used approach is contact measurement, which involves physically touching the plastic surface with a gauge or micrometer. This method offers accurate and precise readings but tends to be time-consuming and requires skilled operators. Micrometers, for instance, can provide precise measurements down to +/- 0.05 mils, making them suitable for thicker films but less accurate for thinner films.
In contrast, non-contact measurement techniques utilize sensors or lasers to determine thickness by measuring the distance between the sensor and the plastic surface. This method is faster and can be automated, but it may not always provide the same level of accuracy as contact measurement. Among the non-contact methods, ultrasonic measurement stands out for its non-destructive nature, allowing it to be used on moving materials for online quality control.
The ASTM (American Society for Testing and Materials) has established several standards for measuring plastic film thickness, providing guidelines for different situations. The D6988 standard, for instance, outlines the use of micrometers for thickness measurement, while D8136 introduces a more advanced technology that incorporates other methods for improved precision and the elimination of issues like dirt on the probe.
Understanding the thickness of plastic is crucial not only for ensuring product quality but also for complying with industry regulations and optimizing production processes. By measuring thickness, manufacturers can detect variations or defects that may impact performance, meet thickness requirements specified by regulations, and adjust process parameters to enhance consistency and reduce waste.
