The BOBST CL 850D duplex laminator is part of the Constantia Flexibles Group investment to expand the operations of Oai Hung Manufacturing Joint Stock Co., the production site in Vietnam, that it is part of its pharma division since 2016. The CL 850D from the machinery manufacturer based in Lausanne, Switzerland, is due for delivery and installation in the cleanroom of the company’s state-of-the-art production facility in Ho-Chi-Minh City in the second half of 2018.

Oai Hung, a company specialised in the production of aluminium blister foil and rigid film for the pharmaceutical market, as well as foil-based lids for dairy packaging, is pivotal to the Constantia Flexibles Group’s expansion in South East Asia. The site is dedicated to serving these high-end market segments, which drove the decision to invest in new equipment at the leading edge of technology.

Coldformed foil packaging is a complex process both in terms of the actual material functionality and compliance with pharma regulations, and in terms of process workflow, operational efficiency and profitability. This is why Constantia Oai Hung and BOBST collaborated closely on the features of the CL 850D in order to meet all the exact specifications relating to output requirements and expected machine performance.

The most complex type of production run on the CL 850D will be an OPA-Alu-foil-PVC triplex compound structure. The guarantee of 100% barrier to external agents and the resistance to stress and puncture of the material, is an essential part of the process even under extreme conditions. Both during the various production processes that the laminates undergo, such as sterilisation, as well as in terms of the product’s long life. To ensure high delamination stability and additional protection of its barrier properties, the Alu-foil substrate is lacquered with an adhesion-enhancer primer before undergoing the actual lamination process.

“We trusted BOBST for this special project due to its know-how and experience in combining process expertise from both coating and lamination technologies,” said Rainer Huber, manager pharma hub cluster, Constantia Flexibles Group, commenting on why the CL 850D was chosen to implement the company’s growth objectives in the region.
