...similar as possible but which have a different composition. One of the two sealing media can be PE, EVA or an ionomer. For the second sealing layer, however, this material is blended with an additional, incompatible component, such as with a polybutene or a polar ethylene copolymer, which mechanically weakens in the continuous phase. During sealing, diffusion takes place between the similar phases in the two layers, thus leading to a strong bond. When the pack is torn open, therefore, the crack...

...lustrate the multi-functional properties of plastics packaging. Packaging for operation tools must be both sterile and easy to open without contamination by fibres. New films developed specially for this area of application are equipped with a polybutene-1 component in their sealing layer to ensure that tearing takes place in this particular area only. These are only a few of the examples presented in our latest issue, but they suffice to provide an insight into the wide range of topics we encou...

Kunststoffe international, 2005-11-21, Packaging Surgical Instruments: Easy and Safe to Open
Packaging Easy and Safe to Open Packaging Surgical Instruments. Easy-open peel packaging has long proved successful for food products. Polybutene-1 (PB-1) is used as a component in the sealing layer. From newly developed films containing PB-1, practical peel pouches for surgical instruments and equipment can now also be produced. Peter Stober Harry Rist In the operating theatre, speed is of major importance during an operation – and that is also valid when opening protective packaging for surgic...

... offer complete solutions for compressed-air generation and distribution, and condensation technology”, explains Berthold Koch, founder and managing director of Beko. Unlike conventional steel pipes, the Bekoflow compressed air pipes are made of polybutene (PB) and have numerous advantages. The most significant is the weight difference. The plastic pipes are about 80% lighter than conventional materials, and PB is heat resistant up to 80°C. The pipelines are resistant to all widely used compress...

Kunststoffe international, 2005-11-21, World-scale Plant: Polybutene-1 Offers Growth Opportunity
Market and Management Polybutene-1 Offers Growth Opportunity World-scale Plant. With its new polybutene-1 production plant in Moerdijk/Netherlands, Basell is seeking to further expand its polyolefin business and is forecasting enormous growth potential for polybutene-1. Basell inaugurated its new plant for producing polybutene-1 in Moerdijk/Netherlands at the start of May. With a planned annual capacity of 45000t, it is reportedly the largest such plant in the world and therefore testimony of...

...uction of such pipe takes place in two steps: In the first step, the pipe is manufactured in a conventional pipe extrusion line. At the end of the line, the pipe is wound onto a reel. The material used is either polyethylene or – in rare cases – polybutene or PE-RT (polyethylene with raised temperature resistance). If the end product is intended to transport a hot liquid, the polyethylene pipe must be cross-linked. After the pipe is wound onto the reel, the drum with the pipe is placed in a se...
