Not Fully Supported By Your Adhesive and Equipment Supplier?

What kind of support should you expect from your Hot Melt Adhesive Supplier and Hot Melt Application Equipment Supplier?  What if they were the same company!

Getting the necessary support from your adhesive and equipment supplier can be crucial to running an effective and efficient packaging operation.  Yet, many companies that use these products may not even know what is possible!  It’s safe to say that not every company operating in a hot melt packaging environment has experts on their staff at detecting or solving adhesive application issues.   This lack of knowledge can make it very difficult when a problem arises.  Further, at a time when adhesive choices are greater and technology is becoming more sophisticated, we are finding more and more that hands on support from suppliers is rare or non-existent. 

Recently we were in contact with a very sophisticated warehouse that does repackaging and distribution for a very well known brand.  They were kind enough to invite us in and to show us their packaging operation.  Within seconds we could see that they were not receiving the proper support from their current suppliers.  The facility contained 7 packing lines, with 3 gluing stations per line.  While observing the lines, we noticed two different problems immediately.  The first problem was that the adhesive being applied to the case was being dispensed improperly, causing it to string or cobweb.  The second problem was the excessive amount of glue being applied.  Most people would believe that this was just a glue issue, but we knew we had to take a closer look at the equipment as well.  

We found the company was using very old Nordson equipment.  Upon further questioning, we learned that the lines were often down due to adhesive related issues, maintenance costs were high, and the correct replacement parts were extremely difficult to find.   We were invited back to perform a more extensive analysis of the operation in which we included a member of our equipment team.  Our proposed solution was to begin using a Dynamelt SR Unit that, quite frankly, seemed extremely optimistic to the customer.  To show our confidence in our solution we offered them a 90 day trial for one of their lines.  After 90 days they reported that the transition was smooth and the equipment worked just as we promised!  The operation was running much cleaner and the glue was no longer stringing.  They are finding the equipment is paying for itself with less down time, less stringing and less adhesive usage per carton.  
If you are wondering if maybe you are not getting the support you deserve or you are not sure "what is possible", please give us a call.  We would love to help solve your problem and find a solution beyond your imagination.

Where to Go When Stitching Your Adhesive is Wearing out Your Modules

Stitching adhesives is a practice that can offer advantages in some industries.  Instead of applying adhesive in one long bead, companies will “stitch” or use small dots of adhesive to cut glue usage and to cut glue costs.   One of the main components of the stitching process is the module.  A few months ago a manufacturer of pleated filters, who was stitching, came to us with a module problem that they could not solve. 

In their process, each glue module was running millions of cycles per week.  The constant opening and closing of the valve was causing the module to fail frequently. This failure was causing scrap, downtime and replacement module costs.  Instead of asking the customer to stop their stitching process and double the amount of money spent on glue, we came up with a solution.  Our suggestion was to enhance the valve to a higher quality product.  We recommended the ITW Dynatec Marathon Module.  This product has proven to be a long lasting and reliable valve.  After replacing their module with our Dynatec marathon module, they eliminated glue dispensing problems in production.  The valve is still being turned on and off millions of times per week but is causing zero problems.  The company converted to the Dynatec valve over a year ago and their module failure problem has been resolved.  The upfront cost of the marathon module was a little higher but that cost was more than overcome by the savings.

Do you have a challenging adhesive or application equipment related problem that you think cannot be solved?  If so, please feel free to give us a call.  We would be happy to go through your process and help you find a solution that goes beyond your imagination!

Going Beyond the Glue

A couple of months ago, a state-of-the-art food processing plant in Ohio started having problems with sealing containers and other gluing issues. As their adhesive supplier, they called us with concern that the adhesive was a different product, a new formulation or even a bad batch.

When you have been using the same adhesive without fail for several months or years and then it starts to fail, you may think there is a problem with the adhesive. More often than not—which was the case for this company—it is actually the adhesive application equipment. That’s where our Equipment Division comes in handy!

Looking at their operations, we noticed they were using Nordson applicators. These applicators were misfiring and misaligning the hot glue which resulted in their containers not getting sealed properly. To compensate, they were using more adhesive to try and correct the problem, which caused a lot of stringing and a lot of waste. When it comes to proper adhesion, using too much glue actually makes the problem worse.

The solution was a simple one and they could not be happier. We changed their applicators with ITW Dynatec BF MicroBead™ applicators which is a perfect and cost effective fit for any Nordson machines. As stated by their production manager, not only has their downtime has been dramatically reduced but their glue consumption as well.

Are you having a problem with your gluing operations? We would be happy to come in and take a look at your entire operations and work with you to find the best solution for your company.

Indispensable Types of Adhesives

There are so many seemingly small yet -in today’s world- indispensible inventions that use adhesive as a main component. Take a look in your home or office, what would we do without transparent tape, sealable envelopes, adhesive bandages or disposable diapers?

These inventions were often created to solve a problem or improve a product. Take furniture pads, for example. Many years ago a young inventor tried to find a solution to stop his chairs from marring the floors. He found that if you soak the thick felt material used for chalk board erasers into a high solids white glue, once hardened, it can be used as pads on the bottom of furniture to protect the floor from scratches.

Sometimes, however, the invention is by sheer accident as in the case of sticky notepads. In 1970, a 3M Adhesives researcher tried to create a super glue-like adhesive, but instead only developed an adhesive that would stick paper together. The invention got shelved until years later when another 3M Adhesives worker was singing in a church choir. He used bookmarks to keep his place in the hymnal, but they kept falling out of the book. Remembering the sticky but peelable adhesive, he coated his bookmarks with it and, voila, Post-It Notes® were born.

Can you think of other clever inventions that have required adhesive solutions as a main component?

Adhesives in Farming

Farming has always been a major part of Ohio’s history and economy. Many of these agricultural farms are family-based businesses that have been producing crops for several generations.  From fruits, vegetables and ornamental plants to dairy, eggs and meats, these Ohioan farms stock grocery stores, garden centers and farmer’s markets throughout Ohio and into other states.

What, you may wonder, does this have to do with adhesives? Adhesives are used in farming for many purposes, from agriculture machines to animal husbandry, but most commonly for packaging and transportation. Because crops and produce must stay fresh and get to their destination undamaged, farmers need to find the right adhesive and packaging solutions for suitable containers and secure transport that maintains top-quality products.

HAR provides agricultural packaging solutions through high performance adhesives to protect products, reduce costs and meet sustainability goals. We offer adhesive technologies for case and carton sealing of corrugated boxes and coated paperboards as well as bonding of paper bags, corrugated fiberboard, PVC and PET clamshells and other flexible packaging.

While adhesives are a small portion of a package, they are an essential component on the strength and durability of any container. The right adhesive can help a package maintain proper ventilation or block out UV rays; stay stable in hot or cold temperatures; resist physical damage; withstand moisture and much more.

To help farmers, HAR provides adhesive solutions for case and carton, flexible packaging and packaging containment and reinforcement that address the unique needs of any distributor.  We are proud to help our local farmers continue to provide the finest and freshest products from farm to store shelf.

To Automate or Not to Automate

The choice to go with an automated or semi-automated adhesive application system versus manually applying adhesive depends greatly on the production needs, time and resources available. In the long run, it is usually more cost effective to use an automated application system because it will use less glue, take less time, use less manpower, make fewer errors and require less clean up. Even with more complex designs, small or large products, or ever-changing requirements, you’ll be surprised at how well an automated system can handle both.

Here are two examples:

  1. A manufacturer of large plywood crates for specialty shipping needs had a problem. Because of the crates large size and weight, they require forklifts and cranes to maneuver yet the packages needed to remain stable. So the manufacturer uses a layer of polyethylene foam—known to have excellent shock absorbing and vibration dampening properties—on the bottom of every crate. The problem came with keeping the foam adhered to the plywood.

They were using a hot melt glue gun to apply their adhesive. The hot melt would start to cure as the person tried to cover the large area. Coupled with too much adhesive being used, this led to a weak bond. The foam was peeling off as the crate was being moved.

We evaluated their requirements and installed a ITW Dyantec adhesive application system with a swirl spray using our standard pressure sensitive hot melt adhesive.  Now, no matter what excessive handling or long-distance transporting, the crates remain structurally sound and the package unaffected. Plus this system has reduced labor and the amount of adhesive needed by almost 40%.

  1. A casket manufacturer (yes, coffins) uses several adhesives in virtually every aspect of constructing a casket including sealing lids to keep them water and air tight. To do this, they used an expensive adhesive tape for gasket sealing which was a cumbersome process and slowed down their entire production line. The manufacturer looked to us to reduce costs and increase efficiency.

We custom developed a semi-automatic adhesive application system for their unique requirements. Using ITW Dynatec equipment and our pressure sensitive hot melt adhesive, this system made the caskets water and air tight in half the time and for half the cost.

Switching to an automated application system will often save a company thousands while being able to keep up with production demand for the long term.

Are you thinking about ways to increase efficiencies in your manufacturing operations?

Shipping "Freezable" Adhesives During Winter Weather

Hot Melt Glue - Freezable AdhesiveWinter is almost here! As the temperature drops and the snowflakes fall, we may think of the holidays, sledding, skiing, a warm fire or even getting away to a warmer climate. How many of us think about glue? If you said yes, you are either a glue sales representative, glue manufacturer or need to get a life!

Seriously, if you order, use, or ship glue in the cold months, you SHOULD be thinking about it! While hot melt glue is mostly immune to colder temperatures, water based adhesives are very sensitive to the cold. Since most water actually freezes at 32ºF, your water base glue will too.

But what if your glue arrives frozen? Just let it thaw? It’s not an option! Once water based glue freezes, it’s probably a goner. Emulsion adhesives, contain very, very tiny glue solids which are suspended by a “protective colloid.” This protection keeps the particles, which are heavier than water, suspended in the water and keeps them from settling to the bottom of the container. When the glue is frozen, the particles clump together and/or fall to the bottom. Glue with all those clumps will never be able to stick anything together. Dextrin adhesives, however, are somewhat different.  Because they are solutions, often times they will be usable after some stirring.

So how do you know if a product is frozen? It’s not always easy. The first thing you need to do is to open the container and do an inspection. If you see lumps floating on the top (looks like cottage cheese), ice crystals, or even worse, a solid, it has been frozen. Feel the outside of the container. If it feels very cold, all the more reason to inspect the liquid itself. Get yourself a thermometer and keep it in your receiving department. That way you can determine the actual temperature when you took it off the truck. This won’t be the absolute determination whether it was frozen or not, but if it comes in at 55 degrees or higher, you can probably feel safe that the product is good.

Another quick check is to see when the product was actually shipped. If you buy in a tote tank or 55 gallon drum, the adhesive has a lot of internal heat. That helps to keep it from freezing. So, short overnight trips typically are not an issue. However, if the glue has been on the road for several days, be very cautious and check the adhesive thoroughly. If your glue left from Ohio on Monday and arrived at your facility in Ohio on Friday, you may have a problem with your adhesive – especially if the weather was very cold. That’s why we never ship waterbased products on a Friday in winter months. If we did, the glue would sit in a truck for two to three days and if the weather is cold enough, freezing would occur.

In winter months we always require that freight companies who haul our “freezable” products protect them from being frozen. When they accept and sign for pails, drums or totes, they guarantee that the material will arrive at your location in good condition. If the product does freeze, the shipping company is responsible.

If you ever suspect that a shipment of water based glue has been frozen, be sure to contact us at 440-786-7185 immediately. As an industrial adhesive supplier and manufacturer, we can help you make a determination whether you should accept or reject the product.

Hot Melt Adhesive: The “Secure” Option instead of Staples

Imagine you just bought an expensive piece of furniture that comes in a box closed with staples.  You take it home.  As you attempt to carefully pull it out of the box the staples that sealed the box scratch your brand new furniture, or worse yet, scratch you!

This was happening far too often for a local manufacturer of high-end outdoor furniture made from poly lumber. The staples they used to seal the corrugated cartons were scratching the furniture as a customer would pull the item out of the box.  Additionally, the staples presented a safety risk to their customers because of the exposed sharp edges.

By way of a client referral, the furniture manufacturer gave HAR a call. We immediately brought in an ITW Dynatec Dynamini™ configured system along with our standard packaging hot melt glue. We evaluated their requirements and provided training on the most efficient and effective way to incorporate hot melt into their packaging operation.  We left the system unit there for a one-week extended demonstration and the company carried out numerous performance tests. With every test performed, our configured system combined with our hot melt technology outperformed the staples and held together perfectly with no failures and no damage to the furniture. They bought the entire system and our adhesive the following week. 

The furniture company came to us to help eliminate the possibility of damaging their products and provide safer packaging for their customers. The added bonus is they also received a hot melt system that we set up to be safer, faster and easier to operate with no increase in production costs.

 Dynamini™ configured system Hot Melt Glue

The Dynamini™ configured system they purchased consists of a Dynamini™ adhesive supply unit, hot melt adhesive hose, DGII™ manual applicator and bead nozzle. This system is a small yet mighty workhorse with a melt-on-demand hopper—that means less energy consumption, safer operation and virtually no adhesive charring or degradation.

Now instead of staple guns, they use the DGII™ manual applicators which are safer and easier to operate and allow for better accuracy. Plus our hot melt adhesive also costs less per unit over staples which will save the money over the long term!

As you can see, hot melt adhesive is a “secure” option instead of staples because it protects against product damage and allows customers to safely unpack the product. Are looking for ways to improve your packaging operations? Look no further and give us a call.

What Do Pringles® Chips, Ajax® Cleanser & Pillsbury® Crescents All Have in Common?

Tough one? Think about the packaging. They are all packaged using composite cans. These cylindrical containers are attractive, functional, versatile and economical, making them extremely popular for consumer packaging needs. And adhesives are an integral part to the manufacturing of composite cans.

Composite cans are just one of the many paper tube products. These containers are used to package countless commodities such as motor oil, frozen juice, table salt, coffee, rolls of paper or foil, games, mailing tubes and fiber drums to name a few. The body of the containers is usually made of spiral wound paperboard but also can be convolute (parallel) wound paperboard. Some of the tubes then are decorated with eye-catching convolute labels to attract consumers.

Composite can construction also allows for various top and bottom closures made from plastic, metal or paper such as shaker tops, pull tabs, snap on lids and more. To further its functionality, the containers can be lined with foil, including food grade foil, to protect and preserve contents. Because composite cans and other tube products are made of paperboard, there is a wide range of wall thickness and sizing options.

HAR Adhesive Technologies has a number of hot melt, dextrin and water based adhesives to manufacture these spiral wound and convolute wound paper tube products. Our adhesives offer both excellent mileage and quick-setting characteristics for improved line efficiency and quality. We have adhesives that contribute to a firmer core for cans and tubes to improve crush strength regardless of the paper core and processing speeds.  If that wasn’t enough, we also supply laminating adhesives for lining the interior of composite cans—including food grade certified adhesives—and labeling adhesives to bond exterior labels.

Can you think of other uses for composite cans? If you are a composite can or other tube winding manufacturer, it may be worth your while to talk with us to find the best adhesive solutions for your production needs. We work with our customers every step of the way to determine the right adhesive and adhesive application to meet all production requirements.
