Four-year deal secures Palram's PVC sheet

The British arm of Israeli sheet manufacturer Palram has struck a deal which secures its production of corrugated PVC sheet for the next four years. An undisclosed German company working in the civil engineering and construction markets has contracted to buy all the Doncaster plant's output, amounting to a minimum of 1,700 tonnes a year. The deal is worth around Eur 12 million.

The air bubbles in plastics parts

The air bubbles is one of the types of surface defects parts. Good to know how to distinguish different types of bubbles and how to eliminate those filled with air. Blank spaces in the form of bubbles formed on parts as a result of entering into the air surrounding it to form and stop by. The resulting vesicles resemble its appearance cavity cramps (wakuole). Why are there bubbles? During the injection stop is surrounded by the air mass, resulting in a part in empty space (air bubble), which may occur in the vicinity of the wall. It is the result of too much or too rapid decompression stroke, low power plastification, as well as problems with the venting (eg, ribs, blind holes). How to distinguish from wakuole bubbles? In the case of the surface defects it is important to distinguish between the air bladders and jam shrinkage. Cramps cavity is empty spaces without air (so-called empty vesicles. Wakuole), which arose as a result of difficult shrinking plastic. Since the air bladders and cavities cramps are similar in appearance, it is difficult to distinguish them from each other. Helpful in their distinction may be part of immersed in water and see whether it affects them (wakuole) or not (gas bubble). The defect, which are air bladders, it is less, where the manufacture takes place without decompression stroke. Changes in pressure at the end of clamping and its duration have no effect on the volume of empty space. Parts, where there are empty spaces, tend to have much less resistance. For items that are not transparent, some of them should be cut in order to ascertain the potential for defects. When the mass injection rate may enclose air, resulting in a part in empty space, which often have less strength. It should be remembered for cutting the items that are not transparent and reviewed them for possible defects. It is important for the differentiation defects in the surface filled with air bubbles from those which are empty. Bubbles on part can be addressed by taking appropriate proceedings, such as reducing the rate of stroke and decompression.

Hostalen ACP 5231 D new extrusion blow molding HDPE

Sales Basell Orlen Polyolefins Sp z oo, which is a wholly owned subsidiary of Basell Orlen Polyolefins Sp z oo, in its commercial offer an innovative variety for the extrusion of the mix company LyondellBasell Industries (LBI). Recently, through the use of new technology under the name Advance Hostalen Cascade Process (ACP) was made at the latest the European market under the name of a species HDPE Hostalen ACP 5231 D, which is recommended for the manufacture of small bottles and containers. Hostalen ACP 5231 D perfectly complements and broadens the range of HDPE products offer LBI recommended for extrusion of blow. The new species is characterized by an optimal combination of density and molecular weight distribution with a very high environmental resistance to environmental stress cracking and high resistance to crushing. Due to the well-balanced distribution of molecular weight, Hostalen ACP 5231 D is not only easy and processing possibility of shortening the time cycle, but also the manufacturing of packaging ensures excellent space. Internal tests, and the tests carried out by a number of industrial customers across Europe in fully confirmed that the new species is easier to process than other species available in the market for HDPE comparable rheological properties, with a wider field of processing parameters. Typical applications are: Bottles for cosmetics and personal care lotions Detergent bottles Bottles and canisters multilayer Toys Jerricans on mineral oil

Retailers beat carrier bag reduction target

Britain's retailers have exceeded the voluntary target to cut carrier bag consumption that they set in an agreement with the Government in 2007 . According to a statement published today by the Waste and Resources Action Programme - WRAP - which has monitored the process the target 25 per cent reduction in the number of bags given out has led to an actual reduction of 26 per cent in 2008 from the reference period of 2006. This has been amplified by other factors to reduce the environmental impact - defined as the amount of virgin material used in carrier bags - by 40 per cent since 2006. In hard numbers, the total number of bags in circulation has reduced from 13·4 billion in 2006 to 9·9 billion in 2008, reducing the weight of material by 23,000 tonnes. WRAP is also monitoring agreements between the Scottish Government and supermarkets and between Defra, the Welsh Assembly Government, the Northern Ireland Department of the Environment and the British Retail Consortium and its supermarket members. Both agreements aim to reduce the number of single use carrier bags issued to consumers by 50 per cent by the end of May this year.

Rexam invests in Mexico

Rexam has bought out its partner Pavisa Industries in a 50:50 plastic packaging joint venture in Mexico. The plant, at Tlalnepantla in Mexico City, is an injection moulding and extrusion blow moulding producer of containers and closures for a range of markets, including pharmaceutical, diagnostic, healthcare, cosmetic and personal care. Graham Chipchase, group director at Rexam Plastic Packaging, said that despite tough global economic conditions, the company remains focused on investing in growth markets. Rexam will use the plant to exploit growth for plastic packaging across the healthcare, closures and personal care industries in the Mexico and Latin American markets.
