When you replace your heat shrink system with horizontal stretch packaging, you will reduce your operating costs significantly. Savings in the figures are based on a specific customer case.
Reduce your operating cost
When it comes to automated packaging of large products and roll materials, heat shrink packaging has in many years often been the solution. However, during recent years heat shrink packaging successfully has been replaced by horizontal stretch packaging. The RoRo StetchPack® machines have proven that horizontal stretch packaging is a profitable alternative to heat shrink packaging, and there are several good reasons for this. Here you find three profitable benefits which instantly lead to significant reductions in your operating costs: savings in energy, film consumption and maintenance.
Reduce energy cost with 90% on your packaging line
One of the main benefits when using a RoRo StretchPack® machine instead of heat shrink packaging is the energy savings. Horizontal stretch packaging is a cold packaging process, which makes it possible to remove the heat shrink tunnel from the packaging line. The tunnel is the most energy-consuming part of a heat shrink packaging line.
A heat shrink tunnel typically has an energy consumption on about 150-200 MWh/year. This corresponds to a saving in energy cost by up to 90% on the total packaging line, when replaced with a RoRo StretchPack® machine. It is a significant saving in the operating cost. Furthermore, your cost for fire insurance will also be lowered, due to the reduced fire risk.
Reduce excessive film consumption for packaging by up to 60%
Film consumption is another area where you can reduce your operating cost with a RoRo StretchPack® machine. When using stretch hood film, you stretch a smaller tubular film to fit the product you want to pack. Opposite when you use heat shrink packaging, you pack your product in a film which is larger than the product and afterwards you shrink the film to fit your product. This results in excessive film consumption when using heat shrink packaging.
When our customers change from a heat shrink system to a RoRo StretchPack® machine, we typically see reductions in film consumption between 25-60%. This corresponds to savings in film cost by up to 50%, when you take the difference in film prices into account.
Easy access for maintenance and minimum production stop
A heat shrink tunnel requires that it cool down before you can start maintenance. Afterwards, the tunnel has to warm up before you can restart production. It means that the maintenance of a heat tunnel causes a long period of production stop. This is not the case when maintaining a RoRo StretchPack® machine. It has no heat tunnel, in which melted film can trigger an alarm, and cause a production stop for cleaning. A RoRo StretchPack® machine only has two wearing parts: the knife and the sealing bar. There is easy access to replace these. This result in a minimum of direct and indirect cost for maintenance.
Supporting the UN's Sustainable Development Goals
There are several more good reasons for using a RoRo StretchPack® machine. In this connection, we will briefly highlight three more benefits connected to the savings mentioned above.
First, you will reduce your carbon footprint when removing the energy-consuming heat shrink tunnel from your packaging line. Next, you will have responsible use of global resources by reducing your film consumption by up to 60%. Thirdly, your working environment will be improved, because you will remove the maintenance and cleaning of a hot shrink tunnel, which both is a hot and extensive job.
Using a RoRo StretchPack® instead of a heat shrink system, will not only reduce your operating cost. You will also reduce your environmental impact with a more sustainable packaging line supporting the United Nations Sustainable Development Goals.
