Do You Know These Five Types of Hot-Melt Adhesive?

Choosing the right hot-melt adhesive for every use is critically important. The adhesive you need to accomplish a specific task can vary widely, so it’s important to know what adhesives are best suited for your application.

Evans Adhesive is proud to offer five different types of packaging hot melt adhesive in addition to our water-based adhesives. Here is a quick look at each of our adhesives and how they could work for you.

hot-melt glues

1) EVA (Ethylene Vinyl Acetate)

Our EVA adhesive is ideal for a variety of coated and uncoated paper product applications. EVA is waterproof and offers some heat and cold resistance and sets quickly, firming up between one and ten seconds after application.

2) Polyethylene

These hot melts work well for case, carton and tray sealing applications. Polyethylene adhesives provide excellent thermal stability and are low odor.

3) Metallocene

Like polyethylene, metallocene adhesives are light colored and low odor, providing excellent thermal stability. Metallocene adhesives are also well-suited to case, carton and tray sealing applications.

ReliaSeal 7359 is an excellent example of an effective Evans metallocene adhesive. Its char-free characteristics help users eliminate downtime and repair expenses that are sometimes required due to carbon buildup in adhesive lines.

4) APAO (Amorphous Poly Alpha Olafins)

APAO adhesives are best used where open time and tack are required. These adhesives offer a soft, tacky and flexible texture, making them an excellent choice for product assembly.

5) Polyamides

An adhesive for high temperature and high strength applications, polyamides are resistant to oils and solvents. This makes them an excellent choice for difficult to bond, low energy substrates.

Benefits and Challenges of Hot Melt Adhesives in Industrial Environments

In industrial use, hot melt adhesives (HMAs) provide several advantages over solvent-based adhesives.  They include:

hot melt

Polyethylene hot melts are ideal for case, carton and tray sealing applications. Polyethylenes provide better thermal stability, are low odor and light colored.

  • Volatile organic compounds that are reduced or eliminated
  • The drying or curing step is eliminated
  • Hot melt adhesives have long shelf life and usually can be disposed of without special precautions
  • HMAs do not lose thickness during solidifying; solvent-based adhesives may lose up to 50-70% of layer thickness during drying

 

Some challenges of HMAs include:

  • Thermal load of the substrate, limiting use to substrates not sensitive to higher temperatures
  • Loss of bond strength at higher temperatures, up to complete melting of the adhesive.
  • Some HMAs may not be resistant to chemical attacks and weathering

 

The above challenges can be reduced however, by using a reactive adhesive that after solidifying undergoes further curing e.g., by moisture (e.g., reactive urethanes and silicones), or is cured by ultraviolet radiation.

 

Popular applications for hot melt adhesives include, but are not limited to:

  • Closing the flaps of corrugated boxes and paperboard cartons in the packaging industry
  • Spine gluing in the bookbinding industry
  • Profile-wrapping, product assembly and laminating applications in the woodworking industry
  • Disposable diapers are constructed through the use of HMA, bonding the non-woven material to both the backsheet and the elastics
  • Many electronic device manufacturers may also use an HMA to affix parts and wires. or to secure, insulate, and protect the device’s components

 

It’s worth noting that mass-consumption disposable products such as diapers necessitate development of biodegradable HMAs.  “Going Green” is important in any supply chain, and that includes your adhesives.

How Paying Attention to Straws is Changing the Environment

Paper Straws

 

“An environmental turning point is lurking in your drink,” says CNBC, and they’re right. The straws you use to sip your beverage of choice at your favorite restaurant could be the next big point of contention in the war on waste.

Seattle, Fort Meyers, and Malibu have already banned plastic drinking straws, and fast food giant McDonald’s plans to eliminate plastic straws at its 1,300 locations in the United Kingdom.

But why the controversy at all?

Plastic straws can be harmful to the environment—but there is a solution

Consider how long you use a typical drinking straw. Even if you linger over your meal, chances are your straw won’t be in use for more than an hour at most. But the plastic used in your straw will never decompose. Even if it makes up just a small portion of the plastic used once and thrown away, it’s still contributing to the growing problem of pollution and waste.

The solution to the waste of plastic straws is simple and has actually been around as long as straws themselves: paper straws. These lightweight, often colorful straws were once common in malt shops and restaurants but fell out of favor as plastic straws became more common. Now, these straws are making a comeback for one simple reason: they decompose completely. Unlike plastic, paper straws will eventually break down in a landfill, resulting in a much smaller impact on the environment.

It may seem like a small thing, but this is a huge long-term benefit. Even though plastic straws may be small, they’re used in huge numbers every day and that plastic adds up. Paper straws can make a small but significant dent in that total.

How Evans plays a key role in paper straw manufacturing

Adhesive is a critical part of the manufacturing process that makes paper straws possible.

If you look closely at the construction of a paper straw, you’ll notice a spiraled line of paper that makes up the straw’s body, very similar to a paper towel roll. Paper straws are obviously much smaller and lighter than a paper towel tube, but both are held together with a small amount of adhesive along the edge of the paper spiral. Evans has been a key supplier in the manufacture of paper straws since the beginning

As paper straws return to prominence, Evans’ high quality, water-based adhesives will be front and center. The next time you’re sipping a drink on a paper straw, remember the adhesive that makes your environmentally friendly drinking option a possibility.

About Evans

Evans Adhesive helps our customers and the US Food & Beverage industry move toward more environmentally-friendly alternatives to plastics! While many states and companies are looking for sustainable options to replace plastic straws, Evans Adhesive offers successful products for use in paper straw manufacturing to help reduce plastic consumption here in the US.”

Common Hot-Melt Adhesive Uses and Applications

Hot-melt adhesives (HMA) are as numerous as they are versatile.  In general, hot melts are applied by extruding, rolling or spraying, and the high melt viscosity makes them ideal for porous and permeable substrates.  HMAs are capable of bonding an array of different substrates including paper, rubbers, ceramics, metals, plastics, glass, wood and more.

 

Today, hot melt adhesives are available in a variety of different types, allowing for use in a wide range of applications across several industries. For use in industrial processes, HMA adhesive is supplied in larger sticks and glue guns with higher melting rates. Aside from hot melt sticks, HMA can be delivered in other formats such at granular or power hot melt blocks for bulk melt processors.  Larger applications of HMA traditionally use pneumatic systems to supply adhesive.

Some common examples of industries where Hot-Melt is used include:

  • Closing the flaps of corrugated boxes and paperboard cartons in the packaging industry
  • Spine gluing in the bookbinding industry
  • Profile-wrapping, product assembly and laminating applications in the woodworking industry
  • Disposable diapers are constructed through the use of HMA, bonding the non-woven material to both the backsheet and the elastics
  • Many electronic device manufacturers may also use an HMA to affix parts and wires. or to secure, insulate, and protect the device’s components

And here are some general terms used for HMA’s:

  • Open time: the working time to make a bond, where the surface still retains sufficient tack, can range from seconds for fast-setting HMAs to infinity for pressure-sensitive adhesives
  • Set time: time to form a bond of acceptable strength
  • Tack: the degree of surface stickiness of the adhesive; influences the strength of the bond between wetted surfaces.
  • Surface energy: which influences wetting of different kind of surfaces.

A Range of Metallocene Hot-Melt Options Available

Hot-melt adhesives not only offer superior performance properties, but also provide manufacturers with a range of metallocene options and capabilities:

Metallocene options are available

  • High-melt metallocene: Applied at 350 degrees Fahrenheit, this gives production operators a smooth-flowing, consistent, and trouble-free adhesive solution for a wide variety of product operating requirements;
  • Low-melt metallocene: Applied at 250 degrees Fahrenheit, this melts to a lower viscosity, so the same amount can be applied at lower pressure, increasing mileage. Low-melt also offers machine operators the added safety feature of working with adhesive at a safer, lower application temperature
  • Packaging-specific metallocene: Formulated for a wide variety of specialized box, carton, tray, and packaging materials, including corrugated plain and inked, coated and uncoated stocks, paper bag stocks, trays, frozen food and ready-made meals packages, and other packaging stocks and configurations.

Comparing Costs: Metallocene vs. EVA Hot Melt Adhesive

Previous posts outlined the advantages of metallocene-based adhesives compared to traditional EVA-based hot-melt adhesives, so now we look at costs.

But what about costs?

Metallocene-based hot-melt adhesive may initially cost more than EVA-based hot melt adhesive. However, the costs associated with problems from char-prone EVA can erase any initial cost savings you may have received.

Costs from problems with char buildup can include:

  • Production downtime expense: Usually the highest cost, which can be calculated from hundreds to thousands of dollars per hour, depending on the operator’s production environment
  • Product defect costs: Packaging defects due to poor carton adhesion, which lead to pop-opens and other package failures throughout the distribution chain, can be a significant ongoing expense, leading to additional negative impacts from lost and damaged products, negative effects on customer goodwill, and potential liability cost

Replacement adhesive applicator parts and service cost: When charring conditions reach the point where the adhesive application system can no longer be cleared, hoses, nozzles, and other affected parts of the system must be replaced, usually at a significant cost in new applicator components and additional costs per hour of service expense.
