Purchasing a stretch wrapping machine can be a significant investment. This investment should be made carefully. There are many types of stretch wrappers available and they can vary greatly in price and feature set. Make sure you understand what you're buying and how it will help your company.
There are two main types of stretch wrapping machines. These are manual and automatic. Each requires a different set of skills to operate.
Manual machines require the operator to manually attach the film to the load, attach the film to the pallet, and unload the wrap. Automatic machines perform the same tasks but without the operator. They have special sensors that can detect when the load is too high for the wrap zone.
The best type of wrapping machine will depend on the type of product being wrapped. Some types of products, such as chocolate bars, can be wrapped in one step. Others, such as razor blades, can be wrapped in two or three layers. These machines can be automatic or semi-automatic.
The most important factor to consider when buying a stretch wrapping machine is durability. In order to get the most out of your investment, consider buying a machine that will last for several years. This will help reduce downtime and increase your ROI.
Another feature to look for is pre-stretching. Pre-stretching can reduce film usage by a significant amount. Pre-stretching can be set for each phase of the wrapping cycle. It can range from a minimum of 120% to a maximum of 500%. This amount of containment is determined by the tension in the film and the number of layers.
