Greenhouses The modern greenhouse is usually a glass or plastic enclosed framed structure that is used for the production of fruits, vegetables, flowers, and any other plants that require special conditions of temperature. The basic structural forms are the span-type greenhouse, which has a double-sloped, or A-shaped, roof, and the lean-to greenhouse, which has only one roof slope and leans against the side of a building. Two or more span-type greenhouses are sometimes joined side by side so that they

What Are the Different Types of Polyethylene? This Is the Main Different Types of Polyethylene : Low-Density Polyethylene (LDPE) : is a very flexible material with unique flow properties that makes it particularly suitable for shopping bags and other plastic film applications. LDPE has high ductility but low tensile strength, which is evident in the real world by its propensity to stretch when strained.Linear Low-Density Polyethylene (LLDPE) : is very similar to LDPE, but offers added advantages. Specifically, the properties of LLDPE can be

Polyethylene Polyethylene is a thermoplastic polymer with a variable crystalline structure and a vast range of applications depending on the particular type. It is one of the most widely produced plastics in the world, with tens of millions of tons produced worldwide each year. What is polyethylene material? Polyethylene is a commonly used plastic material that consists of a long chain of carbon atoms with two hydrogen atoms attached to each carbon atom. Is polyethylene a good plastic? Polyethylene is by far the most
