Muntajat markets a range of thermoplastics under the brand name Lotrène®. Our portfolio includes the full range of the polyethylene family, including low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE), and medium-density polyethylene (MDPE).
Lotrène® has a multitude of commercial applications, such as extrusion coating, lamination, injection moulding, rotational moulding, and the coatings for wire and cables. Our thermoplastics are used extensively in the production of films and sheeting, and go on to become shopping, laundry, and freezer bags, as well as films used for food storage, agriculture, and packaging and shipping.
Lotrène® is also a popular choice for manufacturing rigid plastics, and is used in toys and rigid containers, pressure and non-pressure pipes, automotive parts and fuel tanks, dairy bottles and containers for household chemicals, large blow-moulded drums, industrial liners, pond liners and geomembranes, and pipes and fittings.
Low Density Polyethylene (LDPE)
With a worldwide consumption of around 20 million tonnes per year, LDPE is one of today’s major thermoplastics.
LDPE is a polymer made from the monomer ethylene. It is transparent, robust and at the same time relatively ﬂexible. LDPE has excellent resistance to water, moisture and various organic solvents and chemicals.
LDPE is mainly used for the manufacture of ﬁlms and sheets, but is also used for extrusion-coating, injection-moulding, injection-moulding, wires and cables.
In Qatar, LDPE is produced by QAPCO and marketed under the trademark Lotrène®. QAPCO has a full range of LDPE for the production of industrial and consumer ﬁlms as well as one for coating and two for injection moulding grades.
Examples of applications are: heavy duty bags, pallet shrink ﬁlms, collations shrink ﬁlms, pouches, freezer bags, shopping bags and laundry bags.

Linear Low Density Polyethylene (LLDPE)
LLDPE is one of the major thermoplastics, with a total worldwide production of around 25 million tonnes per year.
LDPE is a copolymer made from ethylene and from an alpha-oleﬁn. LLDPE is a polyethylene with good impact and puncture resistance, good ﬂexibility and high elongation under stress.
Like LDPE, the main application for LLDPE is ﬁlms and sheets. LLDPE is also used in injection-moulding, rotomoulding, wire and cables.
In Qatar, LLDPE is produced by Qatoﬁn and marketed under the trademark Lotrène®. Qatoﬁn’s product range focuses on ﬁlm applications, with four blown ﬁlm grades and one speciﬁc cast ﬁlm grade. All grades are butene-based. This focused industrial strategy makes for the highest quality and consistency standards.
Examples of applications are: bags, packaging ﬁlm, agricultural ﬁlm, stretch ﬁlm, cling-ﬁlm and lamination ﬁlms.

High Density Polyethylene (HDPE) / Medium Density Polyethylene (MDPE)
With a worldwide consumption of around 40 million metric tonnes per year, HDPE is one of today’s major thermoplastics and the most widely used type of polyethylene (PE). HDPE resins include ethylene homopolymers as well as copolymers of ethylene and alpha-olefin monomers such as 1-butene, 1-hexene and 1-octene. HDPE has higher crystallinity (density) compared to low density polyethylene (LDPE) and linear low density polyethylene (LLDPE), which results in higher mechanical properties such as stiffness, modulus and tensile strength, higher temperature resistance, improved barrier properties as well as improved chemical resistance to a variety of solvents and chemicals. HDPE properties can be adjusted by controlling the molecular weight, molecular weight distribution, degree and type of short chain branching and amount of long chain branching to design resins with optimum performance for different end-use applications.
HDPE is used worldwide in a very large variety of applications such as rigid containers, toys, film products, sheet products, injection-molded articles, pressure and non-pressure pipes, geomembranes, automotive parts and fuel tanks, to name just a few.
In Qatar, HDPE is produced by Q-Chem and Q-Chem II. Q-Chem and Q-Chem II have a range of HDPE products focused on blow molding, film, geomembrane and pipe application segments.
Selected examples of specific end-use applications are: household and industrial chemical containers, large blow-molded drums, industrial liners, bags and packaging film, geomembranes, pond liners, and pipes and fittings.
