Vorhersage der mechanischen Folieneigenschaften bei der Schlauchfolienextrusion
The manufacturing of blown films made of thermoplastic materials is considered an important processing technique for polymer raw material. Today, one goal of the further development of the blown film extrusion is the reduction of raw material application while maintaining or improving the quality …

A study of processing methods for producing biaxial orientation in thermotropic liquid crystalline polymers
… extrusion blow molding, biaxial stretching, and film blowing. Some measure of biaxial properties and orientation was obtainable in all four processes, from the layered structure apparent in the blow molded bottles to the uniplanar orientation in the stretched film. Tensile and flexural properties …

Processing and Characterization of Extruded Zein-Based Biodegradable Films
… of this study were to prepare biodegradable zein films by extrusion processing and to evaluate relevant physical properties of resulting films with respect to their potential as packaging materials. The manufacture of protein-based packaging films by extrusion has remained a challenge. In this …

Investigations of Structure–Property Relationships in Semicrystalline Thermoplastic Polymers: Blown Polyethylene Films and Polyacrylonitrile Copolymers
Blown films of high molecular weight high density polyethylene (HMW-HDPE) were produced from two resins of differing molecular weight (MW) and molecular weight distribution (MWD) using a high stalk bubble configuration. The processing conditions were varied such that three film gauges, each …

Development of high-performance recyclable films for food packaging
… geral, combinam diferentes tipos de materiais em filmes coextrudidos ou laminados, permitindo assim melhorar as propriedades estéticas e funcionais (mecânicas e/ou de barreira), mas dificultando a reciclabilidade das mesmas. Uma estratégia para diminuir a utilização de diferentes materiais numa …
