stretch filmThere are two types of packaging machines available, the resistance stretching type and pre-stretching type. The resistance stretching type depends on the resistance between the packaging item and the film frame to stretch the film and wrap the goods, while the pre-stretching type uses a roller in the film frame to wind through the speed difference and then wrap it on the package. Pre-stretch stretch film packaging machines have several advantages over resistance stretch stretch film packaging machines. Pre-stretching provides greater stability and fewer film breaks in the process. By creating a pre-stretching, it reduces the amount of film being used which results in lower product costs. Additionally, Pre-stretching offers better load security, which is crucial to ensure the product isn't damaged during transportation.
2. Stretch film is an essential component for wrapping packaging machines, however, its usage can significantly impact packaging costs. Adopting a pre-stretch stretch film packaging machine can reduce the consumption of stretch film by up to 300%, resulting in significant cost savings. With its unique film frame structure, pre-stretch stretch film packaging machines are able to stretch the stretch film, making it more efficient and economical. By saving stretch film, packaging costs are minimized, contributing to a more profitable business model.
Earlier, we discussed the effectiveness of film exhibition. In this regard, it is worth noting that the resistance stretch wrapping film packaging machine relies on the resistance of rotation to stretch and wind the film. However, this winding method has a drawback. When the original wide film is wound on the object, the film width tends to narrow, resulting in an increased amount of stretch film being used. On the other hand, the pre-stretch stretch film packaging machine tackles this issue. It utilizes an active roller on the film frame to unfold the film effectively while maintaining its original width. This enables the maximum utilization of the stretch film for packaging items. By employing the pre-stretch method, businesses can optimize their use of stretch film and ensure efficient and cost-effective packaging solutions.
The wide scope of application and excellent wrapping effect make the resistance stretch wrapping machine a favorable choice. However, it has limitations when it comes to wrapping lighter items. On the other hand, the pre-stretch wrapping machine surpasses these limitations and can effectively wrap items of various weights. It even excels in wrapping irregularly shaped items. Considering the scope of application, the pre-stretch wrapping machine proves to be more versatile and efficient.
pre-stretch stretch film packaging machine has greater advantages.
