Jelly glue (also called animal protein glue) is an environmentally friendly and strong paper bonding glue, that has always been favored by printing factories and packaging manufacturers. However, in actual applications, due to the different bonding rates of machines of various manufacturers, the requirements for glue will also be different. Generally, it can be divided into high-rate, medium-rate, and low-rate jelly glue. Below, from the perspective of the application range of glue, I will share with you the differences between high-rate, medium-rate, and low-rate jelly glue:
1. Low speed jelly glue
This type of low-speed jelly glue has a relatively slow drying speed. It is mostly used for manual or semi-automatic machine glue. After the paper is glued, the glue will still be sticky within 120 seconds and will not completely solidify. The advantage of low-speed glue is that it has a longer open time, which allows workers to have more time to complete the bonding process. It is suitable for semi-automatic shell machines, laminating machines, and manual bonding.
2. Medium speed jelly glue
Medium-speed jelly glue is mostly used for bonding various gift boxes and books. The curing speed of low-speed glue is slightly faster than low-speed glue, and the drying time is about 60 seconds. Medium-speed glue can enhance the hardness of cardboard and has strong flexibility. It is mostly used in semi-automatic shell machines and mounting machines with heating equipment.
3. High-speed jelly glue
High-rate jelly glue is mostly used to produce hardcover books and hardcover box shells. Most machines are fully automated equipment. This type of glue cures quickly, and the film has good toughness and strong folding performance. The speed of bonding paper boxes can reach 60-80 per minute. The machine can be used for fully automatic high-speed leather case machines.
The above is the difference between high, medium, and low bonding rate jelly glues. When choosing glue, you can communicate with the glue supplier about what type of jelly glue to choose based on your production efficiency and on-site machinery and equipment.
