Xiamen Changsu is once again a long way ahead

When the Chinese BOPA film pioneer and world’s largest producer Xiamen Changsu makes an investment, the industry listens up – fully justified again. They just now ordered two new sequential film stretching lines from Brückner Maschinenbau which are the fastest, widest and most powerful of their kind so far: a working width of 7+m, a production speed of 340 m/min and an output of more than 2.5 tons per hour have not been achieved yet.

Mr. Wang Zhefu, Chairman of Xiamen Changsu says: „When we decided to make this investment, we had a clear goal in mind: lowest production costs with highest film quality at the same time. The new lines surpass our largest machines to date by 35% in speed and 50% in output. And based on our long-lasting experience with the Brückner technology we can safely assume outstanding film qualities with the finishing characteristics our customers expect.”  

Phillip Chen, Managing Director Brueckner Far East is happy about the renewed collaboration: „Xiamen Changsu is one of our longest-standing customers in the BOPA business – not only in China, but worldwide. Since 2003 we have completed 10 joint BOPA projects successfully. They were characterized by great innovative spirit on the part of Xiamen Changsu, who, for example, were the first to use a twin-screw extrusion at BOPA or decided in favour of simultaneous systems with a working width of 6.6 metres.

Reinhard Priller, Sales Director Brückner Maschinenbau, adds: „The new lines also mark the latest development stage in the field of sequential PA film stretching: From 4.2 to 5.1 to 6.6 meter we now reached a proud 7+ meters. And Xiamen Changsu made all these steps along with us – a strong sign of true partnership!“

The lines are to start production in the last quarter 2021, right in time to produce film for the year´s end business.

BOPA films have a variety of exceptional properties such as puncture, impact, burst and tear resistance. Tough packaging demands, outstanding gas barrier properties, a good resistance to oils, greases, solvents and alkalis as well as freezer-suitability are perfectly covered by BOPA films. They are therefore increasingly in demand for the packaging of fatty and oily food, distilled goods, agricultural or medical products. Brückner Maschinenbau offers a proven sequential as well as simultaneous BOPA technology.
