Constantia Flexibles Group’s subsidiary Oai Hung (Vietnam) has selected Bobst’s CL 850D laminator for high performance coldformed foil pharma packaging.
The investment in the CL 850D laminator is part of Constantia Flexibles’ strategy to expand the operations of Oai Hung Manufacturing, which is the group’s production site in Vietnam.
Delivery and installation of the new laminator in the cleanroom of Oai Hung’s production facility in Ho-Chi-Minh City are scheduled to take place in the second half of this year.
Oai Hung is engaged in the production of aluminium blister foil and rigid film for the pharmaceutical market, as well as foil-based lids for dairy packaging.
The expansion of the manufacturing operations in Vietnam is key to Constantia Flexibles Group’s expansion in South East Asia.
Constantia Flexibles Group Pharma Hub Cluster manager Rainer Huber said: “We trusted Bobst for this special project due to its know-how and experience in combining process expertise from both coating and lamination technologies.

“We are confident that the new CL 850D laminator will fulfil our requirements and prove Bobst once again to be a trusted and reliable partner for our lamination projects.”
Oai Hung worked with Bobst on the features of the CL 850D in an effort to meet specifications regarding output requirements and machine performance.
The CL 850D features an OPA-Alu-foil-PVC triplex compound structure, which involves ensuring 100% barrier to external agents and the resistance to stress and puncture of the material during the various production processes and in terms of the product’s long life.
The Alu-foil substrate is lacquered with an adhesion-enhancer primer before the commencement of the lamination process in order to ensure high delamination stability and additional protection of its barrier properties.
According to Bobst, the machine is equipped with the semi-flexo coating trolley.
Bobst’s two-roller vertical solution offers a higher coating speed that will ensure superior quality coating for either solvent-based adhesives or lacquers.
The semi-flexo coating trolley is also expected to provide higher uniformity and a better coating profile across the entire web width.
Additionally, the machine dryer involves both traditional and floatation type nozzles that are anticipated to offer maximum efficiency in evaporating the solvent from the lamination adhesive.
