The terms shrink wrap and stretch wrap are often used interchangeably, but the reality is, they are two different products. While they are both used for packaging purposes and are both clear plastic films, they serve different purposes during application. Understanding these differences can save you the frustration of ordering the wrong film.
Stretch wrap is an elastic film commonly used to wrap and secure loads on pallets for shipping purposes. As the products are wrapped in the film, tension is applied as it is wrapping several times around the load. The properties of the wrap cause it to cling to itself creating a tightly wrapped, secure packaging. Stretch wrap can come in a variety of specialty films such as: UV stretch film, colored stretch film, prestretched stretch film, etc., making it more adaptable than other films.
Unlike stretch wrap, shrink wrap is a clear plastic film that is not stretchy. Shrink wrap covers loosely around a product and shrinks tightly when heat is applied. It is typically used to professionally package retail items giving them a tamper proof and protective barrier. Shrink wrap is mostly used to wrap individual items such as CDs or meats, but can still be used to package multiple items together. Shrink Wrap has the option of being ventilated, which creates an advantage in reducing any damage that can occur from moisture.

The term ‘If it’s not broken, don’t fix it’ still applies to many industries. However, with preventative maintenance that phrase becomes “If it’s not broken, keep it that way.”
With packaging equipment, there are many common problems that can arise. Therefore, it’s important to establish a proper preventative maintenance program. The purpose of a preventative maintenance program is to provide long term maintenance and quality care in order to avoid any unplanned problems that might arise.
Simple preventive maintenance not only extends the life of your packaging equipment, it keeps money in your pocket for the days ahead. Companies that don’t participate in a preventative maintenance program are essentially waiting for a problem to happen, and this is often a very costly move. A case study performed by The Association for Packaging and Processing Technologies shows that PM generates a solid rate of return in terms of risk mitigation and asset protection (Koo 4). In other words, an investment in PM not only pays for itself, but it also produces a huge return on the investment. With PM, efforts are focused on preventing equipment failure rather than responding to emergencies, which has proven to be much cheaper and faster than big repairs.
Without a proper protocol to keep your packaging equipment in good condition , it can be very challenging to run a stable, consistent business. An unexpected failure can result in idle employees, halting the production line, missed deadlines, and long-term damage to their brand. With PM, however, companies are able to recognize problems earlier thereby eliminating the chance of machine breakdowns.
Best Packaging understands the financial impact of a packaging line not running properly or not running at all. Our trained service technicians can assist with your ongoing maintenance requirements to keep your packaging equipment healthy and running at maximum efficiency. We also offer thorough training to make sure your operators are confident running the equipment.
Don’t wait until the entire machine goes down and money is lost while it is out of commission. Prevent major catastrophes by stopping the problem before it starts. Call Best Packaging at (888) 930 BEST or click here to schedule a PM today.
In order for loads to be wrapped correctly for shipping, you must apply the right amount of containment force. Containment force is the number of film revolutions multiplied by the wrap force. There is a right amount of containment force for each load that ensures that the load is stable and held firmly enough. There are a few things you could do to detect the optimal amount of containment force using the least amount of film. For example, you can experiment with different types of stretch film, alter the machine gauges and prestretch levels, or manipulate the wrap force settings. However, the best way to find the ideal containment force is to test the top, middle, and bottom of the load with a containment force tool.
At Best Packaging, we have the testing technology required to measure and determine the proper containment standard in order to make sure your film can maintain a particular load holding force over time.Using our portable film force system, we can help you identify the minimum containment force required to decrease film costs.
You shouldn’t be alarmed if your containment force isn’t distributed evenly throughout your load. In fact, the lowest containment force value recorded should become your target for shipping a stable load. For instance, if you’re measuring various pounds of containment force at the top, middle, and bottom, but you’re shipping without any issues, it’s best to set your containment force at the at the lowest-mid containment standard. Doing so ensures you must have at least the minimum amount of containment force everywhere on the load in order for it to be safe to ship. By understanding the different distribution channels, Best Packaging is able to give recommendations on the appropriate settings when sending out different loads.
Once you’ve learned how to measure and have achieved the right containment force, you’ll be able to enjoy consistently safe loads, and more importantly, consistently happy customers. To learn more about containment force or how we can help you measure it, call us at (888) 930 BEST
