MEAF Machines B.V., a manufacturing company based in Yerseke, Netherlands, produces sheet extrusion machines and deep drawing machines for roll material (inline thermoformer). The company›s strengths include supplying turnkey production lines.
When one of MEAF›s customers was interested in purchasing a new production system for optimizing its production process of packaging sheets for foodstuffs containers, it immediately referred MEAF to Leister. The customer already had a good experience with an existing equipment line equipped with Leister LE 10000 air heaters and Leister SILENCE blowers.
The planned new production system was intended to significantly increase production capacity but also to reduce production costs.
Consequently, the representatives from MEAF suggested equipping the new machine with an antiblock applicator.
In this applicator, a Teflon/water emulsion is applied to the sheets and is then dried in the precisely controlled drying unit. This process is an alternative to the comparatively expensive co-extrusion process which utilizes plastic additives and is usually employed for applying functional properties to sheet surfaces (antiblock, antistatic and more).
MEAF followed the customer's recommendation to invest in Leister hot-air technology again.
With a combination of the latest generation of Leister air heaters and blowers, the drying process can easily keep pace with the accelerated production rhythm, while the control function is optimally incorporated into the process controller.

The SILENCE radial blower is very quiet at 61 dB(A) during operation; it delivers high air volumes and can be installed in all orientations.
It is specially-designed for use at air inlet temperatures from 100°C to 200 °C (212°F to 392°F), and operates without difficulty at ambient temperatures up to 75°C (167°F).
In industrial processes, one blower often supplies several air heaters. In the MEAF design, each pair of LHS 61 L SYSTEM air heaters is supplied by one SILENCE blower.

The LHS 61 series is the first choice when high performance is required in applications.
MEAF production line with antiblock applicator
The successful combination of low-cost material (APET), an efficient process (antiblock applicator) and high-performance hot-air technology (Leister air heaters and blowers) has accelerated the production process and reduced costs; last but not least, the end-users in the process (the customer›s personnel) are also highly satisfied.
For the manufacturer of the machine, MEAF- Machines B.V., the straightforward way in which the Leister devices could be installed proved to be a great relief. This meant savings in terms of time and money.
