High-Density Polyethylene (HDPE) is one of the most widely used polymers in the world. A high-density, thermoplastic material, HDPE was first developed in the 1950s and has since been used in many industrial and commercial applications. Its chemical structure provides greater strength, hardness and chemical resistance than other types of polyethylene due to its high density and regular molecular structure.
Low-Density Polyethylene (LDPE) is a type of thermoplastic polymer known for its flexible, lightweight and soft structure. First developed in England in 1933, LDPE is obtained under high pressure and temperature during the polymerization process. With more branching in its structure, LDPE increases flexibility and reduces density thanks to this feature. It is widely used in many sectors today and is especially prominent in the packaging industry.
Linear Low-Density Polyethylene (LLDPE) is a thermoplastic polymer that belongs to the low-density polyethylene (LDPE) family, but differs structurally. LLDPE is obtained by copolymerization of ethylene with longer-chain alpha-olefins (usually butene, hexene or octene). This production process gives LLDPE a more linear structure and minimizes branching, unlike LDPE. This structure significantly affects the physical properties of the material and gives it superior performance in various industrial applications.

Polyethylene Terephthalate (PET) is a widely known and used thermoplastic polymer. A synthetic polyester, PET is obtained by the polycondensation reaction of ethylene glycol and terephthalic acid. First developed in the 1940s, PET has gained an important place in the packaging industry. A transparent, strong and lightweight material, PET can be found in both rigid and flexible forms and is often used in bottles, textile fibers and engineering resins.
Masterbatch is an additive widely used in the plastics industry. It is basically a mixture containing a high concentration of pigments or additives in a polymer carrier. Masterbatch is used to add color or specific properties to plastic products and is usually in the form of granules before being added directly to the final product. These granules are mixed with the plastic raw material and subjected to various molding and extrusion processes after being melted.
