Some people certainly already know what polyethylene plastic is. But not a few who do not know it. In general, polyethylene plastic is one type of plastic that is often used by the public. Consists of several types. One of them is high-density polyethylene.
Polyethylene or also called PE plastic, is a thermoplastic that is widely used by people in the world. Usually, this material is often used to make plastic bags. However, this material is also used for the manufacture of equipment needed in other fields, such as agriculture. If you don’t know what polyethylene is, let’s look at the following explanation.

The General Definition of Polyethylene
As mentioned above, Polyethylene, or PE for short, is a thermoplastic that is widely used by consumer products such as plastic bags. In the world of chemistry, polyethylene itself is a type of polymer composed of a long chain of ethylene monomers (IUPAC: ethylene). Even in this industry, polyethylene is often referred to as PE, as well as other compounds, such as polystyrene, which is commonly called PS, or polypropylene, which is often called PP.
Polyethylene was first synthesized by a German chemist named Hans von Pechmann. He did so by accident in 1989 while heating diazomethane. When his colleagues Eugen Bamberger and Friedrich Tschirner looked into the white, waxy substance, they discovered that what he had made contained a long chain of -CH2- and named it polymethylene.
Polyethylene plastic consists of several kinds. That’s because of the density and branching of different molecules. One of them is high-density polyethylene. Polyethylene has mechanical properties that depend on the type of branch, molecular weight, and structure of the crystal.
Several Types of Polyethylene
In the market, polyethylene is divided into several types. Some of them are materials that are often used daily by the community. Both on a large and small scale. Both industrial and household scale.
These types of polyethylene are grouped into several sections, high, medium, and low loads. Types that have a high charge include HDPE, which has a high density, high molecular mass UHMWPE, high molecular mass HMWPE, and high-density HDXLPE. Meanwhile, for the medium-loaded group, there is MDPE which has a medium density.
The group with the lowest load is ULMWPE with medium molecular load, low-density LDPE, density LLDPE, and also low-density VLDPE.
High-Density Polyethylene
Of the many types of polyethylene (PE), several types are better known to the public. Those types are HDPE, LDPE, and LLDPE. But this time, we will discuss more deeply high-density polyethylene or HDPE.
HDPE is the raw material for HDPE plastics, which are generally produced in the form of plastic bags, rolls, and plastic sheets. This type of plastic is made from petroleum. HDPE is characterized by a density greater than or equal to 0.941 g/cm3.
HDPE has lower branching than other types. It also has very high intermolecular strength and tension. HDPE can be produced with a chromium/silica catalyst, a Ziegler-Natta catalyst, or a metallocene catalyst.
The branching of the HDPE type is minimal due to the selection of the type of catalyst in its production and the reaction conditions. For this reason, small branches cause HDPE to have high tensile strength. As well as high intermolecular forces as well. High-density polyethylene texture is harder than others. This type of plastic is also able to withstand high temperatures. That is around 120⁰C.
HDPE Plastic Uses
In everyday life, HDPE plastic is often used to meet needs. Like hot food or drink packaging bags, practical bags carry groceries, fruit bags, vegetables and as a base/coating for warm or hot food containers.
For large-scale use, this type of plastic is often used in agriculture, manufacturing, and even factories. One example of its use in agriculture is animal feed wrapping. Farmers use high-density polyethylene to wrap straws which will be stored as animal feed reserves.
Having several advantages, HDPE is often sought after by farmers for their animal feed matters. One example of the advantages given by this type of plastic is that it is resistant to high temperatures. Thus, animal feed that has been wrapped in plastic can be stored outdoors. The temperature can change.
To be able to get this product, you have to find a manufacturer or store that provides it. Usually, breeders will buy in bulk to stockpile or pack too much feed. For that, you need a manufacturer who can meet that need.
You can just come to the store to get it. But you will have better luck by looking for a supplier or manufacturer directly. You have the potential to get a discount if you order in bulk. In addition, the price given by the unit will usually be cheaper.
