Book Description
This report reviews sheet and profile extrusion, wire and cable coating and co-injection, describing both the rheological and structural considerations and the design and selection of machinery. Problems of layer instability and the c094 of layer c098 are addressed, as well as the selection of polymers and the recyclability of coextruded scrap. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.

Book Description
A comprehensive and highly practical survey of the materials, hardware, processes and applications of flexible plastic films. Aimed at a wide audience of engineers, technicians, managers, purchasing agents and users, Multilayer Flexible Packaging provides a thorough introduction to the manufacturing and applications of flexible plastic films, covering: - Materials - Hardware and Processes - Multilayer film designs and applications The materials coverage includes detailed sections on polyethylene, polypropylene and additives. The dies used to produce multilayer films are explored in the hardware section, and the process engineering of film manufacture explained, with a particular focus on meeting specifications and targets. The section includes unique coverage of the problematic area of bending technology, providing a unique explanation of the issues involved in the blending of viscoelastic non-Newtonian polymeric materials. About the author John R. Wagner, Jr. is President of Crescent Associates, Inc., a consulting firm that specializes in plastic films and flexible packaging. He graduated from the University of Notre Dame with a BS and MS in Chemical Engineering.

Book Description
Volume 2 presents the fundamental principles related to polymer processign operations including the processing of thermoplastic polymers and thermosets. The objective of this volume is not to provide recipies that necessarily guarantee better product quality. Rather, emphasis is placed on presenting a fundamental approach to effectively analyze processing operations. The specific polymer processing operations for thermoplastics include plasticating single-screw extrusion, morphology evolution during compounding of polymer blends, compatibilization of immiscible polymer blends, wire coating extrusion, fiber spinning, tubular film blowing, coextrusion, and thermoplastic foam extrusion. The specific polymer processing operations for thermosets include reaction injection molding, pultrusion of fiber-reinforced thermosets, and compression molding of thermoset composites.

Book Description
Flexible films are defined as being planar forms of plastics, which may be thick enough to be self-supporting but thin enough to be flexed, folded and/or creased without cracking. Films comprise around 25 per cent of all plastics used worldwide, around 40 million tons, and are thus a massive market sector. Commodity plastics dominate, with polyethylene and polypropylene together accounting for around 34 million tons. This is an expanding area with increased demand each year particularly in the developing regions of the world and with a move from rigid to flexible packaging. There are many material types used in films from single layer polymers to multilayer structures with tie layers and copolymers. Multilayers permit custom adaptation of material properties from barrier to strength. Technology, such as the orientation of polypropylene, has produced better properties and more valuable materials. High performance plastics are also being used in applications such as telectronics. There are details of the main suppliers including mergers and capacity. coextrusion, casting, extrusion coating, extrusion laminating and metallising. Blown extrusion was the first process used to make films of polyethylene. These processes have advantages and disadvantages depending on the material type in use, the width and thickness of film required. Films are mainly used in packaging for foodstuffs, but there are also substantial market segments for medical, electronic, automotive and construction applications. Specific applications include decorative wrap, form-fill-seal, blood bags, flexible printed circuits, bed sheeting, diapers, and in-mould decorating of car parts (to replace painting and provide a more durable surface coating). Carrier bags and garbage bags are big markets, with imports to Europe; there are environmental concerns about the use of plastic bags and these are discussed in the report. geomembranes and similar applications. PE and PP are the main materials used in packaging films. PET is primarily used in magnetics, optics and telectronics. PVC is found in consumer goods and medical applications, while PVB is mainly used in automotive and construction applications as glazing protection. Multimaterial films account for around 7 million tons of the films produced, with around 95 per cent of this going into packaging applications. These are just some of the examples listed in this market report. Europe and North America each account for about 30 per cent of the total world consumption of plastic films. The plastic films supply structure and individual company information are summarised in the second half of this market report on Plastic Films in Europe and the Rest of the World.
