clear plastic jugsInjection molding is an integral part of U.S. manufacturing and can be found within approximately 16,000 plastic manufacturing facilities across the country. From clear plastic jugs to custom plastic bottles, the plastics industry will likely remain atop the manufacturing sector for many years to come.

Within this important industry, Polyethylene (PE) plastic is one of the most common and most efficient forms of material in use. Here are some common questions about Polyethylene plastic and how it’s used for making various clear plastic jugs and other important products:

What is PE?
Polyethylene is defined as a thermoplastic polymer with variable crystalline structure. It has a very large range of applications depending on the exact type and is one of the most widely produced plastics used across the globe with tens of millions of tons being produced each year. Typically, High Density Polyethylene (HDPE) is the most common form of PE and has a higher density than other forms.

What are the different types of PE?
HDPE is used to manufacture milk jugs, laundry detergent bottles, garbage bins, cutting boards, and dozens of other uses. In addition to HDPE, there are three other types of Polyethylene, including:

  1. Low Density Polyethylene (LDPE) — This type of PE is quite flexible and posses unique flow properties, which makes it particularly suitable to plastic firm applications. LDPE is commonly used for plastic shopping bags and elastic products.
  2. Linear Low Density Polyethylene (LLDPE) — This type of PE has all the advantages of LDPE but involves formula adjustments and requires far less energy than LDPE.
  3. Ultrahigh Molecular Weight Polyethylene (UHMW) — This kind of PE is an extremely dense material with molecular weights greater than traditional HDPE. UHMW can be crafted into threads with tensile strengths even greater than steel. It is used for high performance and safety equipment like bulletproof vests.

What’s the difference between PE and PET?
Polyethylene terephthalate (PET) is a form of PE, but is specifically used for blow molding into plastic bottles, personal care products, and other consumer products. PET is great for packaging materials because of its ability to be durable and lightweight at the same time.
