Traditional Adhesives and Their Limitations
Before the glue stick revolution, people relied on various traditional adhesives, which often had many shortcomings. 😕
Liquid glue, pastes, and even natural substances like tree sap were all used to stick things together. This was the origin of glue.
These adhesives also have quite a few drawbacks. One obvious one is that if there are too many contents in the magazine, the bonding quality cannot be guaranteed. Maybe what was stuck in the morning will fall off in the afternoon.
Although liquid glue is effective, it is well known that it is difficult for us to control the amount of glue that comes out. Who hasn't experienced the disaster of accidentally squeezing out too much glue and having it everywhere? 🙈
On the other hand, pastes usually dry out or clump up quickly, which makes them less suitable for daily use. 🎨💦
According to a study by the Adhesive and Sealant Council of the United States, in the 1950s, traditional liquid adhesives accounted for over 90% of the consumer adhesive market. However, with the progress of society and the demand for more convenient solutions, their limitations have become increasingly apparent.
