From mailers with gift cards to credit cards and more, product attachment and inserting applications are essential to the print finishing process. Whether your company is sending out a promotional flyer or attaching a card, coupon or mailer, selecting an efficient, cost-effective adhesive applicator is important. Obligations to produce excellent print quality, complex folds, special perforations, and the need for speed are rapidly increasing. The level of performance is critical to your brand reputation and the bottom-line that these products maintain their integrity even after reaching the end-user. Furthermore, with today’s competitive landscape, producing these materials with sustainability in mind is a requirement. In our line of business, that means using less adhesive and producing less waste, and so, today, we pulled together what we know to be five excellent ways the right hot melt gun can start lowering your adhesive usage:
1.“Opt-In” on Options. One of the most critical aspects of adhesive application on a mailer or graphic is the ability to customize the adhesive pattern so that the system can maintain the flexibility it needs for each customer’s specific requests. Because accuracy and precision are a necessity, it is critical to administer an adhesive application that meets these standards. In a market that is constantly reinventing itself, whether you need microbeads, large beads, are folding or perforating the mailer, or need 30 beads versus 15 beads, the electric valve that provides you with the ability to select an option from a limitless number of bead sizes and pattern lengths is the way to go. Valco Melton’s Ecostitch™ Valve is one of the only valves to provide these options to its customers.
2. Eliminate Stringing. Another critical aspect to applying a perfect and efficient adhesive pattern on mailers and graphics is the ability to eliminate stringing and provide a clean cut-off. In other words, when the mailer arrives at the end user, it is important that they can open the seal without tearing, ripping, or damaging the mailer. If the end-user tears or damages the mailer that is associated with your company name, it can affect what they think about the quality of your brand.
3. Ensure the Dispensing Valve is Multi-Use. Many mailers are glued with permanent, fugitive, and pressure sensitive adhesive. It is important to have an adhesive applicator that can work with nearly any adhesive to provide the clean finish and quality application you are looking for.
4. Utilize the “Zipper Stitch.” Valco Melton’s Ecostitch™ adhesive applicator applies adhesive in what they have started to call a “Zipper Stitch™.” This adhesive pattern type is truly unique and far superior to the traditional adhesive application method used on mailers. Traditionally, manufacturers would apply a long line or series of lines of adhesive to seal the end piece. More specifically, a large bead of glue is applied to the surface and spread out across the sealing area, which causes the end user to bend, fold, and tear the mailer when opening the seal. The Zipper Stitch is a superior pattern because it provides a perfect, uniform seal across the sealing area. Instead of a thick bead of adhesive stretched across the surface, there is a series of microbeads applied across the surface to provide a seal that can withstand any quality control test. Simultaneously, this allows the “at home” user to open and re-seal the mailer without tearing it. The Zipper Stitch provides a clean opening while eliminating any tearing or other damage. This increases the integrity of the mailer, which in turn gives the end user a more positive experience.
5. Long Lives the Clean Valve! With speed and ceramic materials, electric valves are able to produce a tight closure that pushes out and pulverizes any char or debris that comes through the valve. Essentially, the valve cleans itself. By using a top-down adhesive path and electromagnetic coil, low pressure and large orifice size, the valve is able to virtually eliminate nozzle plugging. Additional features support easy change-outs and variable valve configurations with options like a “quick-connect” coil.
As an example of how powerful a little adhesive valve of this kind can really be, Valco Melton’s Ecostitch™ adhesive applicator is built with a ceramic seat and carbide-tipped plunger. It easily reaches 3000 cycles per minute continuous duty with a lifetime of up to 300,000,000 cycles. This solution has produced every case I’ve seen with instant ROI– Payback has occurred in as little as four months.
By selecting a hot melt adhesive applicator that can achieve these 5 things, your adhesive can be reduced by up to 75%.

If you are a packing list envelope maker, you know that adding envelopes to corrugated boxes can use a lot of adhesive, consequently costing your company a great deal of money. If you could only decrease adhesive usage, you could not only decrease your production costs but also significantly improve your company’s efforts to work a little more eco-consciously. By adding an immediate competitive advantage, not to mention giving your brand something positive to talk about, this little “leg-up” can mean big stuff for your marketing and sales group and add big value to your brand. Unfortunately, most people don’t know how to decrease their adhesive usage. Being that this is what we have been doing for the last 61 years, we have some information that can really help you out.
Generally speaking, the usual choice for adhesive dispensing onto the back of an envelope is to cover the entire surface. Naturally, it seems fail proof; so what more could you ask for? A lot actually. What most printing machinery, envelope makers, and coating manufacturers don’t know is that although this may seem like the right thing to do, it is unnecessary. Of course, this approach works and produces a reliable bond, but there is a better way; an approach that provides a bond equal in strength, but that uses a fraction of the amount of adhesive. This approach is called a window-frame pattern application.
By eliminating the need to cover the entire surface of the envelope with hot melt adhesive, and instead of applying the adhesive in window-frame patterns, you save up to 70% of your adhesive instantly. Coating equipment like Valco Melton’s FlexCoat™ applies adhesive intermittently using independent dosage from two separate channels. This ensures a constant and homogeneous grammage or coat-weight across the entire frame’s pattern. channel 1 dispenses a continuous and longitudinal application, while channel 2 dispenses an intermittent and perpendicular application.
Valco Melton’s FlexCoat coating equipment is the best option for high-speed intermittent coating. The integrated against-roll mount assembly ensures that the coating head is accurately and consistently presented against its chromed back-up roller. After the backside of the envelope has been coated, the packing list envelope is sealed using a second system that applies a layer of adhesive onto the folded tab that will close and secure the envelope.
If you are looking to decrease adhesive usage and achieve instant adhesive savings of up to 70%, finding a coating station that can apply window-frame patterns is a great next step. If you would like to learn more about our coating equipment, you can read more here.
