Metallocene mLLDPE LL7810A injection molding grade plastic raw material

Metallocene Linear Low-Density Polyethylene (mLLDPE) LL7810A is a high-performance polymer material manufactured by PTT Global Chemical. This material is refined through copolymerization with hexene, using a metallocene catalyst at its core. Its unique molecular structure imparts outstanding mechanical, optical, and thermal properties, making it a significant upgrade over traditional linear low-density polyethylene (LLDPE).

LL7810A exhibits remarkable flexibility and strength, with a tensile strength of up to 50 MPa and an elongation at break ranging from 700% to 800%. In film applications, its tear strength is particularly notable, demonstrating balanced tear resistance in both the machine and transverse directions. Additionally, the material excels in optical performance, boasting a gloss level of 35 and a haze of just 13%, resulting in films with excellent transparency and visual appeal.

The material has a melting temperature of 122°C and a low heat-sealing temperature, ensuring high processing efficiency and broad applicability. With a density of 0.918 g/cm³ and a melt index of 1.0 g/10min, LL7810A is highly suitable for various processing techniques such as blow molding, extrusion, and cast film production. It can be used to produce films with uniform thickness as well as sheets and pipes in diverse forms.

In practical applications, LL7810A is widely used in food packaging, pharmaceutical packaging, and industrial heavy-duty packaging films. It is particularly advantageous in the production of frozen and stretch films. Additionally, it demonstrates stable performance in construction materials and agricultural films, meeting durability requirements while offering processing convenience and environmental adaptability.

As a highly specialized material, metallocene linear low-density polyethylene LL7810A delivers exceptional performance, providing innovative possibilities for the packaging industry and related fields. It not only showcases the advancement of metallocene catalytic technology but also opens new application prospects for thinner, stronger, and more transparent film products.
