Download or read book Plastic Films written by Françoise Pardos and published by iSmithers Rapra Publishing. This book was released on 2004 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2017-10-12 with total page 1382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides an exhaustive description of polyethylene. The 50+ chapters are written by some of the most experienced and prominent authors in the field, providing a truly unique view of polyethylene. The book starts with a historical discussion on how low density polyethylene was discovered and how it provided unique opportunities in the early days. New catalysts are presented and show how they created an expansion in available products including linear low density polyethylene, high density polyethylene, copolymers, and polyethylene produced from metallocene catalysts. With these different catalysts systems a wide range of structures are possible with an equally wide range of physical properties. Numerous types of additives are presented that include additives for the protection of the resin from the environment and processing, fillers, processing aids, anti-fogging agents, pigments, and flame retardants. Common processing methods including extrusion, blown film, cast film, injection molding, and thermoforming are presented along with some of the more specialized processing techniques such as rotational molding, fiber processing, pipe extrusion, reactive extrusion, wire and cable, and foaming processes. The business of polyethylene including markets, world capacity, and future prospects are detailed. This handbook provides the most current and complete technology assessments and business practices for polyethylene resins.
