Shrink wrap is a standard product packaging material because it&#;s durable, versatile, and has many applications. However, one size does not fit all. There are three main shrink film materials: polyvinyl chloride (PVC), polyolefin (POF), and polyethylene (PE). Learn the differences between Polyolefin (POF) vs PVC vs Polyethylene (PE) shrink film/wrap to better understand which plastic is best for your packaging.

PVC was once the most common material for shrink wrap packaging. But due to the release of harmful fumes when applying and disposing of the material, companies are slowly using it less and less. PVC was the packaging of DVDs, videogames, CDs, and other non-edible food items. While it has good tear resistance, it&#;s too sensitive to temperature changes and requires ventilation throughout the process of wrapping products because of the toxic fumes it releases.
Polyolefin has become the elite replacement for PVC shrink film because it&#;s safer, has versatility, and has FDA approval for food contact. You can find this wrap on consumer products, such as food, toys, etc. Where PVC is lacking, polyolefin picks up the slack. This plastic may be more expensive, but it&#;s more temperature resistant and far more puncture resistant.
Buffalo Shrink Wrap is a shrink wrap wholesale supplier that sells polyethylene. This is a heavy-duty plastic film that works great for large industrial items or commercial products. Of the other films, this is the thickest and offers the most protection. It&#;s also the only recyclable material on this list. However, it requires more finessing and skill to ensure a decent wrap job on your products and machines.
There are a few significant differences between PVC, polyolefin, and polyethylene. As you can see, PVC isn&#;t the best material to use. The latter two materials are more stretchable, durable, and safer for consumer and industrial products.
Ultimately, you&#;re more likely to choose between polyolefin vs polyethylene shrink film. Whichever one you decide on from there will depend on the product or item you&#;re wrapping. Use Buffalo Shrink Wrap for all your heavy-duty product packaging needs.

Each year, America uses about 141 million tons of plastic packaging. This may sound like a horrifying statistic at first, but it's actually a good thing. Not only does shrink wrap benefit shipping workers in pretty much every industry, but it also is reusable and recyclable.
However, when it comes to choosing what kind of shrink wrap you need for your company or shipping plant, you're going to need to be smart and do your research.
Today, we're going to talk about the difference between PVC and polyolefin shrink wrap. While neither of these types of plastic is inherently better than the other, different companies that have different values and needs are sure to prefer one over the other. Read on so that you can make an informed choice as to which type of shrink wrap will better suit your needs!
Even if you don't know the term, we promise you've seen shrink wrap before!
Simply put, shrink wrap is a thin piece of plastic that can fit around the product as a coating. This is especially helpful in shipping items that you don't want to become scratched or dented. Shrink wrap is also generally what books and files come in when mailed to you.
Generally, there are three types of wrap that can coat items. One of these is tape, which there isn't much to say on- it's a paper and poly adhesive that goes around boxes and seals them up.
Shrink wrap is another type of packaging, and it is placed around products with a sealing machine and a heat gun. Generally, this is made from PVC. However, another kind of shrink wrap is called stretch wrap, and it's made of polyolefin. This wrapping is made specifically for pallet wrapping and can be placed around an item either by machine or by hand. Going forward, shrink and stretch wrapping are the types of wrapping that we're going to discuss.
Now that you know the general run-down on what shrink wrap is, it's time to look into one of the most popular materials that it can be made from: PVC. Read on to learn about PVC shrink wrap, the pros and cons of using it, and the best applications for this material!
Simply put, PVC shrink wrap is a thin piece of plastic that can fit around the product as a coating. It's the shrink wrap that you're probably most familiar with because most DVDs, books, and software boxes are packaged using it.

This coating is especially helpful in shipping items that you don't want to become scratched or dented. Because this wrapping is placed onto products by a machine, it will be even all the way around. You'll need to tear it open by yourself.
As with any material, PVC shrink wrap comes with its specific pros and cons.
Some of the best things about PVC shrink wrap are as follows:
On the other hand, these are the weaknesses of PVC as a shrink wrap material:
Because it's cheaper than polyolefin, you're going to want to use PVC whenever possible.
PVC should be used when you're wrapping up one item and one item only. You can also use it to wrap up multiple items that are the exact same size and shape, like a 2 DVD set. Make sure that there are no large spaces between parts of the item that you're wrapping up- the entire thing should be solid all the way around. Every groove in the item provides PVC shrink wrap with the opportunity to snag on something and tear.
For this reason, PVC is especially good for use with smaller blunted items. You may not want to wrap a giant box up in it, or it's going to rupture on the sharp corners.
While PVC is incredibly useful for many applications, polyolefin is just as, if not more useful, in other situations. Read on to learn what this material is and the benefits of using polyolefin in your commercial shrink wrap system.
Polyolefin is another material that can be used to shrink wrap items. It's also known as stretch wrap since it's a much more stretchy material. Like PVC, it can be fitted over items with a heat shrink gun or a heat tunnel. If you want to wrap an item by hand, though, you'll need to use polyolefin because it's capable of sticking to itself. PVC does not have this property.
Just like PVC, polyolefin shrink wrap comes with both upsides and downsides.
Some of the main advantages of polyolefin shrink wrap are:
Conversely, here are a few cons of polyolefin:
Polyolefin shrink wrap needs to be used when shrink-wrapping items that have sharper corners or are simply larger. It won't tear or snag on the item this way. It's also the material that must be used when wrapping multiple items or bulk quantities of things since it won't tear in the spaces or grooves between items.
You also must use polyolefin when wrapping food because it's not toxic like PVC is.
While neither PVC or polyolefin is a superior material to the other, each has pros and cons that matter in varying degrees for different applications and industries.
