Multipac e-concept thermoforming packaging machines

Multipac has developed several solutions for reducing the consumption of film material, energy and water in the packaging procedure and has integrated these into several of its thermoforming packaging machines.

The use of innovative die technology and optimised die geometry means the film side trim and the seal flanges of the packs can be designed to be narrower, and the partitions between the individual packs can be reduced.

An appropriate pack design can also contribute to giving packs the same stability, with a thinner film, as is achieved with thicker materials. Despite the use of thinner films, the same degree of product protection can be achieved.

In order to reduce the energy consumption of thermoforming packaging machines, the company has replaced the most important compressed-air-operated components with servomotor drive units.

In the case of the R 535 e-concept model, this involves the lifting units in the area of the forming and sealing stations, as well as the STS 10-strip punch for film cutting. The MVP 600 vacuum pump from Multivac also requires less energy than comparable units. The fresh water consumption of the R 535 e-concept is also reduced by the use of a cooling water flow regulator.

An integrated sensor constantly measures the temperature of the cooling water. Fresh cooling water is only fed into the system when the water has reached a certain temperature.

In the case of the compact R 095 e-concept and R 105 e-concept thermoforming packaging machines, the lifting units and cutting units are electrically driven. Due to the use of a closed cooling water circuit, there is no requirement for an external cooling water supply. This means that the compact thermoforming packaging machines only require a power supply.
