Lachenmeier has developed a new generation of stretch film packaging machines that can bring great benefits to end users. This innovative stretching technology, which can significantly reduce costs, improve appearance, and stabilize cargoes, is a joint stretching hood, and is the primary choice for palletizing methods in various industries. By lowering the film thickness, lower operating costs can be achieved while achieving the best cargo stability. The stretching unit developed by Lachenmeier can handle thinner films without overstretching and without damaging the retention of the film.
One of the main advantages of the new stretch hood machine is the use of a hydraulically stretched heavy-duty tensioning unit. Each gripper has a tensile force of more than 1 ton, which greatly exceeds the tensile force of the electric stretching unit of other stretch hood machines on the market.
The new type of stretching unit is controlled when winding the stretch hood film because each step of the winding process from stretching the film to the cargo until the film is released under the tray is completely controlled. A film cover with a smaller circumference than the goods is wound on four stretching units and then stretched to a size just in line with the outer circumference of the cargo. Thanks to Lachenmeier's top stretch film opening system (Patent Application No.: (EP 1.184.281), it is possible to open a controlled amount of film during stretching, avoiding the stretching of thin and crisp films, especially in On the corners of the product, in addition, due to the opening of the film, such weak spots do not appear in the corners after stretching.
When the film is wrapped around the product, the film not only slides away from the stretching unit, but is gently controlled to release, thereby improving the appearance and market value of the packaged product. Lastly, Lachenmeier's film cutting system, where the film cover is released from the stretching unit in a controlled manner, ensures a stable and reliable connection between the goods and the tray, which reduces product damage during transport and thus returns the product. less.
