What is Resin LLDPE LL 6201XR

With the rapid development of multifunctional composite materials, the performance requirements for plastic raw materials are also constantly increasing. ExxonMobil LLDPE LL 6201XR, as a resin lldpe with balanced performance and wide adaptability, has become a popular choice in the field of composite molding and calendering molding with its excellent processing stability, high gloss appearance and excellent stress cracking resistance.

01 | Material highlights analysis: Why choose LLDPE LL 6201XR?

▶ High fluidity + rapid molding

The melt index is as high as 50 g/10min, which makes it show advantages such as strong fluidity, short molding cycle and high efficiency in calendering and composite molding.

▶ Rigid-toughness balanced structure, suitable for a variety of applications

The flexural modulus is 290 MPa, and it has a cantilever beam notched impact strength of 45 kJ/m², achieving an ideal balance between rigidity and toughness, especially suitable for thin-walled products and composite structures.

▶ Excellent thermal aging stability

After adding heat stabilizer, the material has strong heat resistance, and the Vicat softening temperature reaches 91°C. It can be used in medium and high temperature working environment for a long time without deformation and brittle cracking.

▶ High gloss surface, improving product texture

Good surface film forming property brings bright appearance effect, suitable for packaging products and daily product shells that require visual beauty.

02 | Application expansion: meet the composite needs of various industries

● Thin-walled high-rigidity containers

Widely used in injection-molded food containers, daily chemical packaging, medical-grade shells, etc., with both lightweight and structural strength.

● Composite sheet/multilayer film

As an intermediate or outer layer structural resin, it is suitable for packaging materials such as barrier films, cover films, and cold storage bags. It is particularly suitable for structures with high requirements for adhesion and stress cracking resistance.

● Composite matrix

Suitable as a masterbatch or modified base material to enhance the mechanical properties and processing stability of other polymers. It is often used in automotive interiors, electronic component packaging, outdoor products, etc.

04 | Processing suggestions and precautions

Suitable for a variety of molding processes

LLDPE LL 6201XR has good fluidity and thermal stability, and is suitable for a variety of molding methods such as calendering, lamination, and extrusion. It shows good equipment compatibility in the molding of composite packaging films and thin-walled products.

Temperature control suggestions

The recommended processing temperature range is 180–230°C, depending on the equipment and mold; high temperatures may cause a decrease in surface gloss, while too low temperatures will affect melt uniformity.

Pay attention to shear rate and mold cooling

Due to its high melt index (MI=50), it is recommended to reduce the screw speed or shorten the cavity residence time on high shear equipment to avoid degradation; at the same time, reasonable cooling is required to ensure the stability of the finished product size and transparency.

Good compatibility with additives

The material has been added with heat stabilizers. If further modification is required (such as adding masterbatch and UV inhibitor), a compatible system must be selected to ensure that the performance of the final product is not affected.

05 | Comparative Advantages over Other LLDPE Grades

LLDPE LL 6201XR is especially well-suited for composite applications requiring a balance of rigidity, toughness, and surface aesthetics—such as food lid films, personal care containers, and functional laminated sheets.
