Benefits of Metallocene

What is Metallocene Hot Melt?

Metallocene or metallocene blends are hot melts that typically have less volume and are less dense than other kinds of hot melts like EVAs. Metallocene offers optimal strength while using less glue, so it’s great for applications where you need to use less adhesive without compromising strength.

Premium Hot Melt With More Mileage

Metallocene hot melts are typically a little more expensive compared to low-cost EVA formulations, but there can be significant savings on equipment upkeep and replacement parts. Metallocene is extremely friendly on bulk equipment which means no char in your nozzles and hoses. Metallocene also allows for less downtime because the equipment does not need to be cleaned or purged as often. All of these benefits mean that you'll get more mileage out of your adhesives - that means overall more savings!

If you’re looking for reasons to try out metallocene for your hot melt needs, here are five reasons why metallocene can be a great product for a range of applications.

Five Benefits of Metallocene Hot Melt

1. Little to No Stringing

Nothing ruins an application faster than hot melt stringing. It creates a mess, can compromise bond strength, and is a sign of bad hot melt or improper equipment settings. Many stringing issues are resolved by using a Metallocene hot melt. 

2. Eliminates Char or Gel Build Up in Equipment

Metallocene hot melt melts more cleanly and holds up better in the tank which in turn creates less char. Less char means less clogged nozzles, hoses, and ultimately less downtime (that means more profit). 

3. Minimal Odor

Hot melt is a chemically safe adhesive but that doesn't mean it can't stink. Cheap bulk hot melt products, especially in poorly ventilated spaces, can become irritating or intolerable. Metallocene is clean burning and has virtually no odor. 

4. Resistant to Extreme Temperatures 

Metallocene products are of higher quality and also have better heat and cold resistance. This means they can be used for a wide range of applications like freezer/refrigerator food products or microwavable packaging. Always test first to make sure the product is going to work for your specific needs. 

5. Excellent Pot Life Due to Thermal Stability

We touched on this earlier but it's an important point. Metallocene can stay up to temperature significantly longer than traditional EVA products without charring or burning. This means you don't have to turn the tank off and wait for it to heat back up if you aren't going to be using it for a period of time. Again, less downtime means more production. 

Common Metallocene Applications

Metallocene offers many benefits compared to other types of hot melt, but you need to be sure it will work for your specific application. Metallocene is great at lowering the amount of adhesive used, equipment maintenance costs, and downtime while still creating strong bonds and increasing mileage. Some applications that commonly use metallocene are listed here, along with some of our favorite products. 


The Infinity CleanPack is the perfect metallocene for packaging and end-of-line applications. It's specially formulated to bond with cardboard and offers all of the properties of metallocene we previously went over.

Case Carton Sealing

This Metallocene blend formula is a great lower-cost option because it combines both EVA and metallocene hot melts. This formula is a great budget-friendly option that doesn't sacrifice clean melting and pot stability. 

Food Packaging

The Direct Food Contact Safe and Low Odor hot melt is unique because of its ability to be directly in contact with food. Many hot melts are qualified for indirect contact with food but this product is great because all components of the glue are certified safe for direct contact. 

Freezer Application

For freezer-grade hot melt that can stand up to the most demanding temperatures, the Infinity FreezerPack is the product for you. It's often used for food packaging and offers a fast set time and ability to withstand cold temperatures.
