LG Chem in Everyday Life

Growing Crops in Greenhouses at All Seasons - LDPE

Generally, it is difficult to cultivate crops in winter because of the cold weather.

But it is now possible to obtain spring and summer fruits in winter without difficulties.
We can also eat fresh vegetables all through the year. In the future, a lot of vegetables will be available all around the seasons. 
What makes this change possible is the “greenhouse." Greenhouses that are often seen in the surrounding area are the ones built with vinyl films on top of a house frame. Air-conditioning and heating facilities are also available in greenhouses so that you can grow a variety of crops including vegetables and flowers throughout the year.

One of the key materials used to build a greenhouse is the vinyl film.
Various types of films are used for building a greenhouse, but, among them, an LDPE film called low density polyethylene is commonly used.
This is because it is highly penetrable to ultraviolet and infrared lights and is relatively cheap.


◆ LDPE(Low Density Polyethylene)?

LDPE, which stands for low-density polyethylene, is a synthetic resin which is manufactured by polymerizing ethylene. It is one of the most commonly used plastics in our life. Its excellent processability, flexibility and transparency make it a raw material for transparent films, wire sheaths, and diverse wraps. LG Chem produces LDPE using the latest advanced high-pressure technology.
