What is Pre-Stretch

The Importance of Pre-Stretch with Stretch Wrappers: Maximizing Cost Savings

In the world of packaging and shipping, ensuring that products are securely wrapped and protected is paramount. One of the most effective tools for this task is the stretch wrapper. However, as you dip your toe into your automation journey, you might not understand the true value that a stretch wrapper provides to your operation, especially concerning pre-stretch. Thus, understanding pre-stretch can lead to substantial cost savings and enhanced efficiency.

What is a Stretch Wrapper?

A stretch wrapper is a machine used to wrap pallets of products with stretch film, a highly stretchable plastic film that keeps the items tightly bound. This wrapping process helps to stabilize the load, protect products from dust and moisture, and reduce the risk of damage during transportation.

Understanding Pre-Stretch

Pre-stretch refers to the process where the stretch film is mechanically stretched before application to the pallet. Modern stretch wrappers are equipped with pre-stretch mechanisms that elongate the film, usually up to 250% of its original length. This means that a meter of film can stretch up to three and a half meters.

Cost Savings with Pre-Stretch

1. Reduced Film Usage: By stretching the film, you use significantly less material. For example, if you pre-stretch the film to 250%, you nearly quadruple the coverage, leading to substantial savings on film purchases.
2. Lower Shipping Costs: Pre-stretched film is lighter yet just as effective. This reduction in film weight can lead to lower shipping costs, especially when dealing with large volumes.
3. Improved Load Stability: Pre-stretched film maintains better tension, ensuring that the load remains stable during transit. This reduces the risk of product damage, leading to fewer returns and less waste.
4. Enhanced Efficiency: Stretch wrappers with pre-stretch capabilities often require less manual intervention, allowing employees to focus on other tasks. This boosts overall productivity and reduces labor costs.

Conclusion

Investing in a stretch wrapper with pre-stretch capabilities is a smart move for businesses looking to optimize their packaging process. Not only does it enhance the security and stability of palletized products, but it also drives significant cost savings. By understanding and implementing pre-stretch, companies can achieve greater efficiency, reduce material costs, and improve their bottom line.
