Do you want to guarantee perfect and secure envelopes to your important customers? If you have not yet considered this, I would suggest starting now. According to the Envelope Manufacturers Association, “Adhesive‐related issues are the number one cause for customer returns.” Some envelope converters may say, “Our envelopes open and stay closed just fine.” Is this acceptable? An experienced converter will know to ask a customer where the envelopes will travel or how they will be stored to enable the right selection of adhesive. But, in regards to actually applying the glue, what are the right questions to ask? If you are buying envelopes, I’d likely be impressed with any additional knowledge on the subject. This type of expertise could be what helps decide to use one envelope converter over another.
So, what do professionals consider a secure envelope? In technical terms, a secure envelope has at least three folds and two overlapping edges, with seam gumming applied to the overlapping areas. There may be discrepancy on how well the seam is glued.
To ensure a secure envelope, the manufacturer should have systems in place that apply adhesive consistently, with clean cut-off. There are a variety of envelope types that may need glue application, however closed seam envelopes are the strongest form of seam construction and they are also the least vulnerable to breaking or popping during the mailing process. The operator must consider the specific method of application, the machines involved in the process, and equipment speeds to ensure the right applicator style is selected. Paul Chambers, Vice President of Sales and Marketing at Valco Melton explained, “A 0.35mm nozzle is the right choice for side seam gumming, because it applies gum lines consistently, thus eliminating the inherent problems associated with using improper nozzle sizes, such as tailing and clogging.”
In addition to proper gumming, quality inspection will ensure that the adhesive has been accurately applied at high line speeds. Quality inspection will assure an end user that the important documents inside their envelopes are secure, without manual operator intervention. If you have ever had to manually check envelopes for quality, you know that this is a big time-saver. Specifically, quality assurance gum inspection sensors guarantee that envelope side seam flaps are glued flawlessly in volume, start and stop, and overall length.

You might hold a preconception that direct mail marketing is phasing out in comparison to other inbound marketing techniques such as online marketing, but that is not the case. The direct mailing marketing industry holds their own in comparison to other marketing channels. In fact, according to a Direct Marketing Association Response Rate Report, direct mail outperforms all digital channels combined (mobile, email, social media, paid search, and display advertising) by nearly 600%.
The report brings to light the many benefits of direct mail marketing. According to the study, the best performing format for direct mail is oversized envelopes, with a 5% response rate. In addition, direct mail offers strong return on marketing investment. The return on investment for direct mail is the same as social media (15-17%).
Direct mail marketing won’t be going away anytime soon. According to the 2015 DMA Response Rate Report, “Marketers continue to embrace multi-channel marketing, with 44% of the respondents using three or more channels for their marketing efforts. In these instances, the most popular channels tend to be email, direct mail and social media.”
However, there are some qualms that tag along with direct mail marketing. The most common concerns are the cost to deploy the mail and the difficulty of tracking it. Systems that simplify and streamline the folding and gluing operation for mailing applications as well as inline product scoring and perforating, plow folding, card tipping and gluing in one package can help minimize costs associated with deploying direct mail campaigns.
The ideal solution and systems to deploying direct mail campaigns include accurate dot, line or stitch patterns that have the capability of plow folding and gluing half fold, letter, fold, z folds, and gatefolds. In addition, a system for creating self-mailers in C, V and Z fold formats is best.
A system that feeds, registers, scores, perforates, glues and folds at speeds in excess of 50,000 pieces per hour will save time. In addition, a simple, easy to use pattern controller will increase an operator’s usability. Affordable solutions that are in compliance with current postal requirements for bulk mail are available.
For bookbinding equipment such as perfect binder machines, having an energy efficient hot melt dispensing system that can quickly meet full production melt rates is crucial. Technological advances have increased the number of available adhesive dispensing options for side gluing applications, but one in particular stands out.
Conventional pot filling systems are commonly used with bookbinding applications. The melt unit’s pump size and control can be configured as required for specific application needs and are equipped with precision controls to ensure stable temperature and promote adhesive pot life.
However, with adhesive sitting idly in the chamber, glue pots also experience adhesive degradation, charring, and maintenance problems caused by plugged nozzles.
When it comes to upgrading your bookbinding equipment, high-speed hot melt glue guns offer an attractive solution for side gluing. Not only is it more cost effective than purchasing an entirely new machine to increase efficiency, but they also offer a range of other advantages including:
Some high-speed glue guns can reach up to 3000 cycles per minute and can be set to run on stitch mode to apply minimal adhesive beads with virtually no stringing. These types of effective extrusion systems offer highly accurate bead placement and more uniform glue volume, which translates to a reduction of up to 75% in adhesive usage.
There’s virtually no stringing with high-speed hot melt guns, which translates into a higher quality end product. Normally, when stringing occurs, it forces operators to cut the edges where there is an excess of adhesive. With a cleaner cut off, this requirement is eliminated.
When stringing occurs, adhesive can get into the bookbinding equipment and interfere with proper functioning. The cleaner cut off offered by high-speed hot melt guns prevents this from happening, resulting in less maintenance. Additionally, all-electric high-speed hot melt guns contain less dynamic seals, preventing the constant replacement of spare parts and diminishing performance commonly associated with pneumatic valves.
From increased glue savings and reduced maintenance to more accurate adhesive application, when combined together, high-speed hot melt glue guns deliver a higher quality book and offer a more efficient and effective means to upgrading your perfect binder.
