A Brief Buyer's Guide To LDPE Sheets

Posted on: 25 October 2021

Low-Density Polyethylene, popularly known as LDPE, is a plastic that is used in many industries today. All manner of manufacturers in industries like food and beverage, packaging, and electrical companies use this material for innumerable purposes. If you are interested in LDPE and want to know how useful it can be to your business, this piece is for you.

Properties of LDPE

LDPE is well-known for its soft and flexible properties. This material's softness and flexibility come from the fact that it has an increased number of branches. In a nutshell, LDPE comes from Polyethylene (PE). PE is a product of ethylene polymerization. Experts often adjust the polymerization process, which results in the high branching that makes LDPE soft and flexible. When it comes to molecular chains, the ones in LDPE are tightly packed and organized. That classifies the material as a semi-crystalline polymer. You can use this property to differentiate low-density propylene from other amorphous plastics with highly disorganized polymer chains.

Moreover, LDPE has high elasticity, meaning you can stretch it, and it will deform rather than break instantly. That is why it's primarily used to make items like grocery bags, which cannot be manufactured from brittle, easy-to-fracture materials. LDPE's tensile strength at room temperature is around 7.0-16MPa; therefore, it can only support a reasonable maximum load. Lastly, LDPE materials and products are recyclable. That means any plastic waste made from LDPE is reusable. As a result, LDPE is the material of choice for environmentally conservative manufacturers concerned about the environment suffering when they use materials that will end up in landfills after getting used once.

Applications of LDPE

Low-density polyethylene has many applications in industries like:

1.       Construction

LDPE Sheets are widely used in the construction industry. Construction companies often use them to make vapor retarders, flooring, window films, and to protect countertops. Moreover, as a contractor, you can use LDPE sheets as a drainage layer in pavement construction. And, if your business deals with infrastructure, you can use LDPE sheets when laying runways, roads, and terraces.

2.       Packaging

The packaging industry heavily relies on LDPE. Manufacturers in this sector prefer this material because it's moisture resistant, lightweight, and durable. That is why they prefer making products and items like bags, sacks, caps, closures, bottles, and coatings out of it.

3.       Automotive

Many of the lightweight exterior parts you find on most vehicles are made from LDPE. In addition, professionals in the automobile industry prefer connector caps made from this plastic because they are flexible and therefore easier to apply and remove. Besides, if you want to mask an unwanted shape in a vehicle, LDPE stretch fit cover caps do a fantastic job. That is why, if you are in this industry, LDPE sheets are a must-have.
