Types of LLDPE Resins
LLDPE Resins are commonly used in packaging films. These films are usually transparent or white and are produced in a variety of formulations. They vary in transparency, tear strength, formability, and printability. Because of their low cost, LDPE is a popular choice for many packaging applications. For example, it is a popular choice for living hinge applications and is often used in food packaging.
The ExxonMobil(tm) LL 1001AV is an ethylene 1-butene linear low-density polyethylene resin with good drawdown, puncture and gloss properties. It is often used in blends with other LDPE resins. The take-up ratio greatly affects the surface properties of the blended resin.
There are several trade names for this material. The ExxonMobil Chemical Company and Dow Chemical Company offer a wide range of LDPEs under their respective brand names. They may have a melt mass flow rate ranging from 0.2 to 100 g/cm3.
The INDORAMA 010FS LLD PE Resin is a butene co-monomer-based linear low density polyethylene copolymer. It is produced through the sclairtech solution polymerization process and is used for a variety of applications. Its properties include low gel content, narrow molecular weight distribution and high strength. Its properties make it ideal for extrusion blown film and other applications. It can be blended with other polymers such as HDPE or LDPE.
010FG LLDPE Resin is a versatile resin that is used in a variety of applications. It is an ethylene-butene copolymer and is produced in a low-pressure gas phase process. This material offers excellent processability and mechanical properties and is used in various applications such as film extrusion and rotational molding.
010FG LLDPE Resin offers high impact and puncture resistance, excellent stretch and flexibility, and good shearing resistance. These properties enable it to produce films that are thin yet tough. In fact, the resin is available in two forms: rigid and flexible. The difference between the two is that LLDPE is more dense and thick, while LDPE is less rigid.
010FG LLDPE Resin is a non-porous material that is incredibly resistant to stains. In fact, most paints will not adhere to LLDPE Resin. In addition, it is easily cleaned with a pressure washer. Additionally, it is 75% lighter than other materials.
The SABIC(r) LLDPE 118WJ is a linear low density polyethylene resin. It is suitable for general-purpose applications, with high tensile strength and puncture resistance. It also has a high slip factor and is TNPP-free. The resin is approved for use in food packaging.
It is a good blending partner, and can be used for rotational moulding, storage tanks, and general-purpose applications. It also has high clarity, good tensile strength, and a good hot tack property. This material has a low degree of warpage, making it ideal for many industrial packaging applications.
ExxonMobil(tm) LL 1001BU LLDPE Resin is a popular blend partner with LDPE resins for excellent drawdown and puncture resistance. It does not contain TnPP intentionally, but does exhibit excellent abrasion and puncture resistance.
This high-molecular-weight, low-friction polymer exhibits high stiffness, excellent impact properties, minimal warpage, and minimal slip. It is a suitable choice for extrusion coating applications, including paperboard coating and flexible packaging. In addition, it exhibits good processibility and processing stability, and is UV-stabilised.
LDPE is a polymer with a density of 0.8 to 915 g/cm3. It has a low initiation, high modulus, and low blocking tendencies, making it suitable for use in food packaging films. It also exhibits good impact and flex crack resistance, making it an excellent choice for applications requiring high sealing performance.
Polyethylene films exhibit strong relationships between crystal orientation and mechanical properties. 2D scattering X-ray spectroscopy (SAXS) can evaluate crystal orientation by evaluating the azimuthal intensity profile of scattering maxima. The azimuthal intensity profile of the LLDPE 9085 film is depicted in Figure 5d. These profiles are used to estimate the Herman orientation function, a fundamental property in polyethylene films.
Films made from different LLDPE resins exhibit different degrees of orientation. The orientation of the crystals in the films affects their MD tear strength. A film with a higher orientation of the crystals will have a lower MD tear strength. Using the Elmendorf tear strength as a comparison, it is essential to understand how different LLDPE resins affect MD tear strength.
Crystal orientation plays an important role in shrinkage behavior at elevated temperatures. The higher the crystal orientation, the greater the shrinkage at elevated temperatures. Different co-monomers can also affect the shrinkage behavior. The blown film process produces more crystals with lower melting points.
118NJ LLDPE Resin from SABIC is a butene linear low density polyethylene resin. It exhibits good tensile strength and puncture resistance and is suitable for general-purpose packaging. Its film is clear and thin-gauge and has good hot tack properties. It is a TNPP-free resin. It is also a good choice for co-extrusion.
