Shrink wrap is basically a wrap that’s put around certain items. There are two types: pallet and het. Both are a bit different, and have different additives, along with material. There are vast usages, which is why both matter. There are also different measurements you can use, including gauge conversion to fully understand this. Heat shrink wrap by the thickness is great for different uses.
Pallet Kinds of Shrink Wrap
First, you’ve got the pallet ones, which actually sit around different items, stretching in order to bundle them.
The first kind starts at 25 and goes up to 37 gauge. This is the pre-stretched, and usually, this is thinner, and a lot less resistance to puncture. This is for lighter skids, and for boxes that are stacked, but you should never use them around different corners that are shocked.
Then, there are 42-63 types of gauges, where you have a stretch wrap with decent load retention, which is great for those who need a uniformed wrapping. It’s not resistant to puncture, and you can use this with a load that’s under 2000 pounds, provided that there are no sharp corners.
Then, you’ve got the standard 65-90 gauge wrap, which is the one that’s good for stretching just about anything and is resistant to puncture.
You can use both blown and cast types based on the thickness. They have cent puncture resistance, but the extrusion that’s blown is a lot better. These are basically good for practically anything.
Finally, you can go above 90 all the way to 150. This is strictly for hand wrapping, since this is one that the machine can’t get enough tension for. It’s thicker, but it’s some of the best if you really need something with top-level strength, and resistance to puncture as well, especially for those putting together huge items.
What about Heat
Heat treated shrink wrap requires heat for it to actually seal anything. This is something that’s used in a lot of products, rather than around the boxes.
You’ve got the lowest starting at 45 and going up to 50. This level is the one that's made from polyolefin that’s crosslinked, in order to create a thin, but strong type of film. You see this in different chocolate, produce, electronics, soaps, and even baked goods. This works in machines too for ease of use.
Then there is the 60 gauge, and this is used for PVC, crosslinked, or regular polyolefin types of plastic. This is used for the seals that are tamper-evident on different bottles and the like, and also is considered centerfold kinds of shrink wrap. This is thinner and is good for a lot of products that are consumable. It’s also strong enough to fit different types of items that have sharper edges, especially those with metal kinds of sides to this.
75 gauge is probably the most popular, and it can wrap different products, weighing around 15 or so pounds, depending on the stress from transportation after you’ve wrapped this. This is one that’s good for products that need it, but you should make sure that you ship this one with a box, since it can sometimes cause the seal to break in a few cases. You have 100 gauge too, which is good for combo packs, up to 25 pounds of packaging, and it’s got real good tear strength. Then there is 125-150 types of gauge shrink wrap, which is made for sleeves and seals, but also is for heavier applications. Shrink wrap has a ton of different benefits, and there are so many to choose from.
