Introduction of Pressure-Sensitive Adhesive
In the 1960s, pressure-sensitive adhesive made its first appearance on postage stamps, marking a departure from the traditional lick-and-stick stamps that had been used since 1840. While many stamp collectors initially regarded this innovation as a gimmick, it soon proved to be a practical solution for countries with humid climates, where traditional gum had a tendency to get messy. Sierra Leone, Tonga, and Bhutan were among the first countries to issue self-stick stamps with pressure-sensitive gum, but it wasn’t until 1974 that the United States joined this growing trend with the release of the 10-cent Dove Weather Vane Christmas stamp.
The Benefits of Pressure-Sensitive Adhesive
Pressure-sensitive adhesive revolutionized the way stamps were affixed to envelopes and other surfaces. Stamp collectors no longer needed to lick the back of a stamp or use additional adhesives. The pressure-sensitive gum allowed the stamps to stick securely with just a gentle application of pressure. It provided convenience and cleanliness, eliminating the need for moistening and avoiding the potential mess caused by traditional lick-and-stick methods. Stamp collectors also appreciated the ease of handling self-stick stamps, as they could be easily removed from backing paper without damaging the stamp.
Pressure-sensitive adhesive was initially seen as a novelty, but it quickly became the future of stamp gum technology.
The Impact on Stamp Collectors
The introduction of pressure-sensitive adhesive had a significant impact on stamp collectors around the world. As self-stick stamps became more widespread, collectors had to adapt their collecting methods. The new adhesive posed challenges for those who preferred to use hinges to attach stamps to album pages, as hinges did not adhere to the backing paper of self-stick stamps. Additionally, collectors of used stamps faced obstacles in removing self-stick stamps from envelopes, as they couldn’t be soaked off like traditional gum stamps. These challenges required collectors to develop alternative techniques for preserving and displaying their collections.
Despite the initial resistance and challenges, stamp collectors gradually embraced pressure-sensitive adhesive as a valuable addition to the stamp collecting hobby. The convenience and ease of use offered by self-stick stamps made them a popular choice among collectors, especially for those who preferred to avoid the hassle of licking and sticking traditional stamps.
Challenges Faced by Collectors
The introduction of self-stick stamps presented collectors with unique challenges, particularly for mint and used stamp collectors. Let’s explore the difficulties they encountered and the solutions they found.
Mint Stamp Collectors
For mint stamp collectors, the challenge arose from the fact that self-stick stamps didn’t easily adhere to album pages using traditional hinges. They had to find alternative methods to affix these stamps securely to their collections, ensuring their longevity and preservation.
Used Stamp Collectors
Used stamp collectors faced a different obstacle – the removal of self-stick stamps from envelopes. Unlike traditional gum stamps that could be soaked off, self-stick stamps required a different approach. Collectors often resorted to cutting out a portion of the envelope to preserve the stamp attached to it. However, this method wasn’t always ideal, especially when dealing with bulk mail or bar code routing labels, as it could lead to staining, discoloration, or deterioration of the self-adhesive gum over time.

Despite these challenges, collectors have found creative solutions to overcome the hurdles imposed by self-stick stamps. Let’s move forward and explore the chemistry behind pressure-sensitive adhesives, shedding light on the different types of adhesives used on postage stamps.
| Type of Adhesive | Benefits | Challenges |
|---|---|---|
| Rubber-based adhesives | Penetrate paper, becoming brittle | Darken, lose adhesive quality over time |
| Synthetic polymer adhesives | Archivally safe, easily removable | Can leave a permanent gummy residue if not removed |
Understanding the chemistry behind stamp adhesives allows collectors to better navigate the challenges posed by self-stick stamps. Through careful handling and removal methods, collectors can ensure the preservation and longevity of their stamp collections.
Next, let’s delve into the history of the United States’ journey with self-stick stamps, exploring the various experiments and initiatives introduced over the years.
Chemistry of Pressure-Sensitive Adhesives
Pressure-sensitive adhesives used on postage stamps can be classified into two main categories: rubber-based adhesives and synthetic polymer adhesives. Let’s explore the characteristics of each type.
Rubber-Based Adhesives
Rubber-based adhesives were commonly used on self-stick stamps in the 1970s. These adhesives have the ability to penetrate paper, but over time, they become brittle, darken, and lose their adhesive quality. While organic solvents can be used to remove these adhesives, their long-term preservation poses challenges. Despite their drawbacks, rubber-based adhesives provided an initial solution for self-stick stamps.
Synthetic Polymer Adhesives
Since 1989, self-stick U.S. stamps have utilized synthetic polymer adhesives. Unlike rubber-based adhesives, these adhesives soften and swell in the presence of organic solvents, allowing them to be more easily rubbed away. However, if left in place, they can leave a permanent gummy residue. This type of adhesive offers advantages in terms of removal and usability, while still posing some preservation concerns.
Choosing the right adhesive is important to ensure the stamp’s long-term preservation and usability. Archivally safe adhesives are being continuously developed to address the challenges faced by collectors and provide a balance between adhesive effectiveness and stamp preservation.
United States Self-Stick Issues
The United States Postal Service (USPS) has been at the forefront of experimenting with self-stick postage options, revolutionizing the way we send mail. These innovative advancements have provided convenient and efficient solutions for both customers and postal workers.
Self-Adhesive Stamps
In 1989, the USPS introduced self-adhesive stamps, eliminating the need for traditional lick-and-stick stamps. The inaugural self-adhesive stamp was the 25-cent Eagle and Shield stamp, featuring a patriotic design that resonated with collectors and the general public.
Autopost and ATM Stamps
The USPS went on to experiment with self-service Autopost computer vended postage, enabling customers to print their own postal labels easily. This innovation streamlined the process and reduced waiting times at post offices.
Additionally, the USPS introduced self-stick stamps specifically designed for automatic teller machines (ATMs). These stamps allowed customers to purchase postage conveniently when using ATMs, providing a quick and hassle-free way to obtain stamps.
Postage Validation Imprinter (PVI)
In 1992, the USPS introduced the Postage Validation Imprinter (PVI), a significant advancement in the transition to self-stick postage. The PVI replaced traditional lick-and-stick stamps at post office meters, allowing for seamless application of postage to letters and packages.
The Postage Validation Imprinter (PVI) marked a significant shift in the USPS’s approach to postage, embracing the benefits of self-stick technology. Since its introduction, the production of self-adhesive stamps has steadily increased, keeping up with the evolving needs of customers and the demands of modern mailing systems.
With these experiments and innovations, the USPS has paved the way for efficient and user-friendly postage options, making it easier than ever to send mail and packages.
| Year | Innovation |
|---|---|
| 1989 | Introduction of self-adhesive stamps |
| 2000 | Autopost computer vended postage |
| 2005 | ATM stamps |
| 1992 | Postage Validation Imprinter (PVI) |
