Lldpe Resins for High Output Blown Film Extrusion
Journal of Plastic Film & Sheeting, 1991We take a closer look at the output rate improvements which can be achieved as a result of the improved melt strength of 0.5 MI resins.

Edible antimicrobial films made from starch/gelatin (S/G) incorporated with different ε-polylysine hydrochloride (ε-PL) contents were developed by low-temperature extrusion blowing process. ε-PL addition reduced the complex viscosity and storage modulus of blends, while promoted the formation of hydrogen bonding among film components.

Blown Film Extrusion of LLDPE/LDPE Blends
Journal of Reinforced Plastics and Composites, 1999An experimental study was carried out to investigate the effect of LLDPE/LDPE blend compositions on the physical properties of blown films and processing properties during extrusion. Spiral mandrel die analysis was also performed by FAN method and its results were compared with measured die pressure.

Investigation into the Cooling Characteristics of Blown Film Extrusion Lines
Journal of Reinforced Plastics and Composites, 1999To analyze and to optimize the cooling conditions at blown film extrusion lines, the cooling air stream has been determined by using a hot wire anemometer. The velocity and temperature profiles of the air stream and the air pressure along the bubble have been measured.

High performance extrusion blown starch/polyvinyl alcohol/clay nanocomposite films
Food Hydrocolloids, 2018Abstract Starch/polyvinyl alcohol (PVA)/clay nanocomposite films with high mechanical and barrier properties were prepared by extrusion blowing. Based on the starch/clay matrix, the effects of PVA content on the starch/PVA/clay nanocomposite films were investigated. Appropriate preparation conditions were determined by the rheological behavior of the

Production and characterization of sodium caseinate edible films made by blown-film extrusion
Journal of Food Engineering, 2014Caseinates are considered as an interesting raw material for making biodegradable and water-soluble packaging. However, the development of plasticized caseinates, especially sodium caseinate, has mainly focused on the formation of films obtained by solution casting.

Studies on blown film extrusion. I. Experimental determination of elongational viscosity
Journal of Applied Polymer Science, 1975AbstractBlown‐film extrusion experiments were carried out to investigate the elongational flow behavior of viscoelastic polymer melts at different melt temperatures. Materials chosen for study were high‐density polyethylene, lowdensity polyethylene, and polypropylene.

Real-time Raman spectroscopy during LDPE/PP bilayer blown-film extrusion
Plastics, Rubber and Composites, 2005AbstractThe present study reports on a technique for real-time Raman spectroscopic measurement of crystallinity of the individual components of a bicomponent film (LDPE/PP) during blown-film extrusion. The 1296–1305 cm−1 band, observed predominantly for PE, was slightly masked by the contribution from the PP layer.

Electron beam crosslinking of extrusion-blown LDPE films: 1. Mechanical properties
European Polymer Journal, 1999Polyethylene films obtained by the extrusion-blowing process present anisotropic physical characteristics. This feature provides them with several interesting mechanical properties for numerous industrial applications. In this report, the effects of the electron beam treatment on such materials are presented.

Investigations of film thickness variations in blown film extrusion when using air guiding systems
Journal of Plastic Film & Sheeting, 2020The mass throughput and thus the productivity of a blown film line strongly depends on heat transfer from the film. Existing cooling systems are therefore constantly being further developed. Usually, the film is convectively cooled by cooling rings, coupled with an internal bubble cooling (IBC) system to increase the surface area and the cooling rate.
