Sadico, Vietnam, gets new bag conversion machine

A new PP block bottom valve bag conversion machine has been installed and commissioned for Sadico in Vietnam. BSW Machinery, a subsidiary of Windmöller & Hölscher, took on the project, which enables Sadico to produce a more sustainable packaging solution for its customers in the cement industry.

Cement sacks made from woven PP are a core product in Sadico’s portfolio. The company introduced the AD proTex bag design to its customers, and is now able to produce both single and 2-ply AD proTex sacks on the newly installed converTex SLC from BSW. The AD proTex sack will not only allow lighter bags and reduced material consumption but will also avoid sewing or gluing of the sack with adhesives. Instead, the block-bottom valve sack can be sealed with hot air.

“The installation and start-up of the machine was much easier and faster than we expected,” says Chairman and General Director Mr. Nguyen Phu Tho, adding that “…it was nearly a plug-and-play process – within no time we were able to produce the sacks for our customers. This was the result of the excellent team work between Sadico and BSW engineers.”

“We are permanently running at full speed with the converTex, and all that with the usage of locally available resins and raw materials,” adds Vice General Director Mr. Nguyen Van Cuong. “The responses from our clients are very positive, and so is our outlook.” Sadico was able to convince their customers of this new sack design through intense trials and research. All this was supported by local representative Mr. Le Ngoc Anh from Rieckermann together with the BSW Asia Pacific team Mr. Rene Winkler and Mr. Till Martens. 

“Through the excellent support from the local sales team we were able to convince our customers to change to the AD proTex sack even faster,” says Mr. Nguyen Phu Tho, “and this upgrade of our production line is certainly bringing us on a new quality and efficiency level”. Together with the converTex, Sadico also invested in the extrusion coating line ecoTex 1600L and advanTex circular weaving looms. “Altogether, we are very satisfied with the performance and the operations of the equipment supplied by BSW.” 

The converTex SLC is the newest development in a long-standing tradition of bottomer manufacturing. Since Windmöller & Hölscher engineered the first converTex back in 1994 about 300 machines have been installed worldwide. While the first machine generation was able to reach a production rate of up to 30 bags per minute, the new SLC is now capable of producing 120 bags per minute. The machine is ideal for the Asian market, suitable to produce both 1 ply and 2 ply sacks including the use of paper or film inner liners.
