The production of diverse film products is made possible through blown film extrusion, a pivotal process in the plastics manufacturing industry. This method is integral to creating a wide array of films, ranging from agricultural coverings to flexible packaging for food and consumer products. The process involves forcing molten polymer through a circular die to produce a tube, which is then inflated to form a bubble and cooled before being flattened into film. This paper by TLD Vietnam offers a comprehensive insight into blown film and how it is revolutionizing the industry and paving the way for new opportunities for

PET sheets find applications in various industries. In this guide, TLD Vietnam delves into the detailed sequential stages of extrusion, along with the features, innovations, and trends that will shape the industry’s future.  What Is PET Sheet Extrusion? PET sheet extrusion refers to the production of PET (Polyethylene Terephthalate) sheets through a thermoplastic extrusion process, in which PET resin is melted and shaped into flat sheets by passing through a die. The extruded sheets are subsequently cooled, trimmed, and cut to specified dimensions. Owing to the automated and continuous nature of the extrusion process, consistent thickness and stable product quality

Selecting a packaging material requires balancing performance requirements (thermal resistance, impact strength, chemical resistance), functional needs (rigidity, seal integrity, formability), product protection across the supply chain, and overall material and logistics costs. When material selection is aligned with real service conditions such as temperature exposure, mechanical loads, and handling environments, the risk of deformation, cracking, and product damage during distribution can be significantly reduced. This blog by TLD Vietnam begins with Polypropylene packaging, providing clear insights into the benefits and drawbacks of commonly used Polypropylene packaging solutions.
