Pallet shrink wrap can be confused with a few different materials. People often look for rolls of a material that stretches to conform tightly around pallet loads of goods. Anyone searching will find a plethora of options online. Be sure you know about the common misunderstanding before purchasing pallet shrink wrap.

Below are twelve misconceptions people have about pallet shrink wrap. Anyone purchasing in bulk should read this before making a purchase. Pallet shrink wrap is a general term, be sure you purchase the products you need.
First, if you are looking for a true pallet shrink wrap, there are thicker pallet heat shrink materials used to shrink and conform to pallet loads of products. The most common of these are pallet shrink bags. Premade bags to fit various pallet sizes are made from a thick polyethylene shrink material to slide over pallet loads of goods to shrink and conform to hold and protect the load. Another less common method for heat-shrinking pallets is using a thick industrial or marine shrink wrap. Most marine wraps are opaque and colored either blue or white. Some new machines and equipment are often wrapped and sent out with this heat shrink material, but it is not often used for wrapping pallet loads of goods.
Most people searching for pallet shrink wrap want something they can pull tight around products to hold and unitize during shipment. This material is a stretch film, though people call it shrink wrap. Because the wrap is pulled tightly around the products, it appears shrunk and conformed. The wrap does the opposite and expands to wrap around the skid. With the proper amount of stretch, less film is used, and loads are held tighter together. This form of ‘pallet shrink wrap’ does not shrink down.
Though the term ’80 gauge’ is still popular, many are using an equivalent 80 gauge wrap due to increased petroleum prices. The equivalent materials are thinner than an actual 80-gauge film but are said to have the same holding strength. Thinner yet stronger films can reduce waste and have comparable tension, but they still do not offer the same puncture resistance as a standard 80 gauge.
In addition to the equivalent films, several other thicknesses are available to fit the needs of many scenarios. Lighter materials can protect and wrap half loads or load with less weight. In contrast, thicker 100 gauge can be used for large and heavy pallet loads. There are many different selections available when choosing a pallet shrink wrap; consider other options if applicable to save on money, waste, and possible product damage.

Hand-sized rolls with extended cores are most often available. The rolls are perfect for wrapping furniture and bundling boxes and household items. Because of the cost and thickness of the film sold at these stores, we recommend buying pallet shrink wrap in bulk if using any volume. There are more options, better quality, and lower prices for purchasing materials in bulk.
This difference in stretch rate is intentional because of the consistent tension a pallet wrapping machine can maintain during the wrapping process. During hand application, users can not pull hard enough as they apply film to reach 250% or more stretch. If a hand roll is used on a wrapping machine, it may not work with the film carriage. If it does work, there will still be waste by not obtaining the total amount of stretch the machine is capable of.
Unless using a pre-stretched pallet wrap, users must pull the roll as the load is being wrapped. Without pulling and tightly wrapping the products, they can topple over and move during shipping.

Here are some things you can discuss with Clearmount. There are unidirectional films and bidirectional. The film is stretched so it will shrink when heated and in framing we use bidirectional films. Thinner films shrink faster but also shrink at the seal line so they are not as neat when heated.
Decades ago I used miles of this stuff and here is what I would do if I were buying some now. I would call Clearmount and tell them what I'm using as a sealing method and the gun I use. In the past I have used the very expensive guns but found that I liked the heat guns made for stripping paint from Home Depot and Lowe's best. They are lighter and very inexpensive so for 20% of the cost of the pro models you will only get half the life and way less aches and pains if you do a lot.
Ask for samples of thicker films that shrink evenly rather than the thinner films that shrink faster. You will find these cut cleaner with the heating element and have less chance of developing holes. My preference when cutting is to tug away from the heating element with slight and constant pressure so it tears away as it seals. The faster shrinking film don't react well to this technique. The faster shrinking and usually thinner films work best in a heat tunnel in a production line setting.
This stuff is so cheap that paying a little bit more for a better film will save you thousands in time and hassles before you have finished a roll. Get some samples and buy what works the way you work.
