We recently posted a shrink wrap reference guide on our other packaging blog. The guide is a compilation of information and links about heat shrink wrapping products, machines, and applications. We publish a lot of content about heat shrink wrap and stretch wrap on our website and both of our blogs. Often times it can be difficult for someone interested to find all of the information in one place, a reference guide is a great way to make information quick and easy to find. Since we have had such a good reception to our shrink wrap reference guide, we decided to make a stretch wrap reference guide.
Like our other guide we figured the best way to list all of the information is to answer questions often asked in the buying process with links and materials to help buyers make decisions about products. We recognize there may be some questions that are not addressed for each individual buyer. We welcome the opportunity to discuss any questions you may have. Call us at 1-800-441-5090 if you would like to speak with a sales associate.
What is stretch wrap?
Shrink wrap and stretch wrap are often confused by buyers new to packaging. The easiest way to differentiate the two is to remember shrink wrap uses heat to shrink and conform to the product or products being wrapped. Stretch wrap uses cling to stick to itself when wrapped. See the references below for further explanation.

How Can Stretch Film Benefit My Business?
One of the primary reasons companies use stretch wrap is to reduce product loss during transportation. The proper film can save companies thousands in reduced product loss throughout the year.

Ho Do I Increase Efficiency and Reduce Stretch Film Cost?
After finding the proper stretch film many companies begin wanting to reduce overall film cost. There are two primary options for reducing stretch film cost. The first option is to increase efficiency when wrapping loads. The best way to reach maximum film efficiency is switching from hand wrapping to machine wrapping. If that is not a preferred option, proper hand pallet wrapping will increase film efficiency as well. The other option is to reduce film cost is down gauging with an equivalent stretch film.
Equivalent stretch films are made from different resin formulas to make film thinner and stronger. An equivalent stretch film may only have a 63 ga. thickness but offer up to an 80 ga. holding strength. Use the references below for ideas on how to reduce stretch film costs.
We posted a tutorial on Behance explaining how to properly stretch wrap a pallet. One tool that is not used in the tutorial to help increase efficiency is a stretch film dispenser with a braking system. An adjustable break enables users to reach maximum stretch potential of the pallet wrap. Most users do not reach the full stretch potential of the film, therefore wasting film and increasing cost.
