Five decades from its first introduction, LLDPE has undergone significant development in various applications, particularly in film production. Its linear structure with short branches of comonomer has enhanced its properties, focusing on excellent toughness while maintaining good clarity. From the original LLDPE, produced with the fabulous Ziegler Natta catalyst, to the present-day rise of metallocene […]

Phthalates are chemicals used to improve the flexibility and durability of certain plastics, most used in PVC. Polyolefins such as PP and PE generally do not require any plasticisers like phthalates or any other comparable substances. However, there is potential residual traces of phthalates in polypropylenes, as part of catalyst residue. Some of them have

Packaging industry has experienced rapid growth in tandem with the demand of increasing global population, by safeguard for the enclosed product, extending its shelf life, and introducing unparalleled convenience to consumers. In order to provide stiffness/rigidity and guarantee moisture and gas barrier, the majority of flexible packaging structures incorporate a combination of materials, including Polyethylene

What is gas-fading phenomenon? Gas fading is a yellow or pink discoloration that happens when atmospheric pollutants like nitrogen oxide gases react with phenolic-type antioxidants. It’s a common issue with polyethylene films. Even very low levels of NOx species can discolor an extruded film or molded article at any stage of the processing life cycle—extrusion

Occasionally, we come across the term ‘bimodal’ in the technical datasheets or marketing introductions of certain polyolefin resins. Bimodal represents a distinctive method in production technology, and materials with bimodal characteristics possess unique attributes that position them as advanced solutions for specific applications. In this article, let’s delve into bimodal materials and explore the processes
