Steady State Modeling and Dynamic Analysis of Film Blowing
… analysis, which has never been applied to film blowing, was used to explore the effect of system disturbances on the process. Results showed that perturbations related to heat transfer and inflation pressure were more significant than the effect of die swell. In addition, crystallinity is …

Ultrasonically Assisted Single Screw Extrusion, Film Blowing and Film Casting of LLDPE/Clay and PA6/Clay Nanocomposites
… used in packaging industry. Blown and cast films were manufactured from the prepared nanocomposites. To achieve one step film processing, an online ultrasonic film casting was developed. Ultrasonic waves caused high-energy mixing and dispersion due to the acoustic cavitation, causing the …

Study of antimicrobial polymeric packaging films containing basil extracts
… antimicrobial (AM) agents in polymeric packaging films to enhance microbial stability of foods may have a crucial effect on extending the shelf life of packaged food products or on maintaining food safety. Linalool and methylchavicol are the principal constituents of basil and exhibit an AM effect …

Development of LDPE-based antimicrobial films for food packaging
… on naturally derived AM agents and polymer films containing AM agents derived from basil, for example, exhibit an AM effect against a wide spectrum of microorganisms. Due to the relatively high temperatures involved in manufacturing such films, however, there is a considerable evaporation …

Development and evaluation of low density polyethylene-based antimicrobial food packaging films containing natural agents
Antimicrobial (AM) films containing naturally-derived AM agents, thymol or carvacrol, were developed. These agents were incorporated into a low-density polyethylene (LDPE) substrate using the techniques of both compression moulding and extrusion film blowing. Different film formulations containing …

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 …

Thermorheology and processing of polyethylene blends : macromolecular structure effects
… in polymer processing operations such as film blowing. These phenomena are explained in terms of the surface to volume ratio of the extrudates.

Linking the Rheological Behavior to the Processing of Thermotropic Liquid Crystalline Polymers in the Super-cooled State
… melt strength, such as extrusion blow molding, film blowing, thermoforming and multilayer coextrusion. Our laboratory has developed a unique method to increase the viscosity of TLCPs by first raising the temperature above the melting point (Tm) to exclude all solid crystalline structure, and …
