LDPE (Low Density Polyethylene)

LDPE from Piedmont Plastics

Low density polyethylene (LDPE) is a flexible, lightweight performance plastic material known for its durability and wide range of uses. As a branching form of polyethylene, LDPE has a lower density than linear varieties like HDPE, thanks to its loosely arranged molecular structure. This gives LDPE its unique combination of softness and strength, making it ideal for many everyday applications.

LDPE offers excellent impact resistance, resists stains and moisture, and has strong electrical insulating properties. It’s also transparent, which allows for better light reflection, an added benefit for products that need visibility or clarity.

You’ll find LDPE in many common items, such as plastic wraps, flexible packaging, and food or beverage containers. It’s also widely used in the medical field for making orthotics and prosthetics due to its safe and adaptable nature.

At Piedmont Plastics, we offer LDPE sheet and rod stock to meet your specific project needs. Whether you're in packaging, medical, or manufacturing, LDPE is a reliable material that gets the job done. Contact us to learn more or request a quote today!

Key Features of LDPE

LDPE boasts a wide range of features that make it an asset to many different industries. These qualities include:

Flexibility and Toughness: LDPE offers excellent flexibility and durability, making it well-suited for applications in industries such as medicine and food handling.
Chemical Resistance: LDPE resists chemical attacks very well and remains insoluble in most organic solvents at room temperature.
Impact Resistance: This material’s strong impact resistance makes it a great choice for uses such as impact pads and prosthetic devices.
Ease of Processing: With excellent machinability and thermoforming capabilities, LDPE is easy to work with and well-suited for producing fabricated parts.
Moisture Resistance: LDPE has near-zero moisture absorption, making it ideal for food handling and for producing containers, bottles, and bags.
Transparency: LDPE film's transparency and light-reflective properties make it terrific for applications like packaging and film.
Heat Sealing: LDPE’s relatively low heat resistance and melting point make the film material suitable for heat sealing applications.

Benefits of LDPE

LDPE contains a variety of advantages that make it desirable for use in industries such as packaging, medical, and electrical, thanks to its flexibility, chemical resistance, and excellent low-temperature performance. Contact our team of experts today to learn how LDPE can benefit your project!

Frequently Asked Questions

Low density polyethylene (LDPE) is a flexible, chemical-resistant plastic used in medical, industrial, and packaging applications. This FAQ covers the most common questions about LDPE’s properties, uses, and more to help you determine if it’s the right fit for your project.

It depends on the application. LDPE is more flexible and impact-resistant at low temperatures, while HDPE (High-Density Polyethylene) is stronger, stiffer, and better suited for structural or high-strength needs.

Yes, many LDPE grades are FDA and USDA compliant and approved for direct food contact, making them suitable for use in food storage containers, films, and liners.

LDPE stands for Low-Density Polyethylene, a thermoplastic known for its flexibility, low density, chemical resistance, and excellent performance at low temperatures. It is commonly used in packaging, containers, liners, and tubing.

LDPE is valued for its flexibility, chemical resistance, and moisture barrier properties. In industrial settings, it’s commonly used for chemical tank liners, protective sheeting, tubing, and wire insulation. In the medical field, LDPE is used in orthotics, prosthetics, IV bags, laboratory tubing, and disposable medical containers or packaging. Additionally, LDPE is widely used in packaging applications such as shrink wraps and squeeze bottles, and in construction as vapor barriers and waterproof films.

Yes, LDPE is recyclable and classified as Resin Identification Code #4. However, its recycling availability depends on local facilities, as not all centers accept soft plastics.
