The Meypack shrink wrappers of the SW Series are available as both single roll and also as double roll shrink wrappers.
Machine types of the SW Series that utilise the single roll technology are distinguishable by the absence of a sealing beam and have only one seal because the products are only wrapped by one roll of film. This is a distinct advantage when printed film is being used, not only because of the bottom seal but also because the printed film can be precisely centred. These machines can be operated at a speed of up to 100 cycles per minute. Two and three lane systems are also possible.
Machine types of the SW Series that utilise a double roll technology use a sealing beam, which can be quickly and easily changed. The two film rolls create two seals. This is well suited for less complicated packaging requirements and is available for low or medium speed outputs of up to 40 cycles per minute.
Film packaging has long been not just something used as transport packaging. Much more often it serves as sales packaging – specially printed, it completes the sales unit. For this, the market demands film that is as thin, stable and inexpensive as possible. Correspondingly, there are high expectations placed on the film cutting device to cut the individual sections of film precisely with repeat accuracy. Not only the wear-resistant film cutting device but also the low-maintenance machine execution and the use of printed film are notable advantages of Meypack’s film cutting device.
The design of the shrink tunnel is essential for a good shrink-wrapping result. Through custom-built ventilation channels – intermediate walls for when products are being run in multiple lanes – an optimal shrink-wrapped appearance can be ensured.
In addition to an electrically powered shrink tunnel, the Meypack modular system also offers a gas-powered execution. Thanks to its environmentally friendly design no external ventilation is required.
Experience shows that the gas-powered shrink tunnel will have paid for itself within 1 to 2 years.
Fast film roll changes as well as ergonomic loading must both be ensured.
Due to the continuously changing requirements placed on the film and the product, Meypack offers a modular system featuring a variety of executions that enable the film roll changes to be carried out as efficiently and ergonomically as possible.
Depending upon the task, Meypack offers semi-automatic or fully automatic film roll changes.
