Direct conclusion: EVA hot melt adhesive particles have fast curing, high initial adhesion, and affordable price, making them the main force for book binding and carton sealing; APAO hot melt adhesive particles have a long opening time, wide temperature resistance range, and good flexibility, making them more suitable for large-area composite and weather resistant applications. The two are not about who is better, but about each managing their own aspects.
| Comparison item | EVA hot melt adhesive granules | APAO hot melt adhesive granules |
|---|---|---|
| Base resin | Ethylene vinyl acetate copolymer | Amorphous poly (alpha olefin) |
| Opening hours | Short, a few seconds to over ten seconds | Long, up to tens of seconds or even minutes |
| Initial adhesion and curing | High initial adhesion and fast positioning | Mild initial adhesion, adjustable fit |
| heat resistance | Generally, high temperatures are prone to softening | Better, more balanced in heat and cold resistance |
| Typical use | Wireless adhesive binding, sealing, and pasting of boxes | Mattress composite, automotive interior, sanitary materials |
| Price | relatively low | relatively high |
The pursuit of graphic and text fast printing and printing binding lines is fast: gluing, binding, pressing, and cutting can be done in one go, and the short opening time of EVA adhesive particles perfectly matches. The high-speed sealing of cardboard boxes is the same, and it takes a few seconds to complete the pressing and shaping process. And for large-scale operations that require first gluing and then slowly aligning and bonding, such as display rack mounting and irregular box lining, APAO’s long opening time is the only way to make a difference. Sunlife hot melt adhesive has mature models for both types, and Guangzhou Sunlife Trading can help customers match the opening time according to the process rhythm.
Q: Can two types of glue particles be mixed in one pot?
No. Different resin systems can cause delamination, slagging, and nozzle blockage during mixing and melting. It is important to clean the pot before changing the adhesive.
Q: Is it necessary to upgrade APAO for book binding?
Conventional adhesive binding is unnecessary, EVA has a higher cost-effectiveness; Only export books and periodicals with special requirements for high and low temperature resistance will consider special formulas.
One sentence: Choose the opening time according to the process rhythm, choose the temperature resistance according to the usage environment, and choose the right system is more important than choosing the expensive one.
Answer directly The surface of laminated business cards is dense and has low polarity, making it easy to “fake stick” when directly glued. The key is to choose the right adhesive type, treat the surface well, control the temperature and pressure, in order to stick firmly. Operating Steps Choose adhesive:Used for adhesive film and PVCHot […]
‘Flattening’ refers toThe book back can be completely flattened, and the cross page image is not broken by the middle seamAlbums, photography collections, recipes, map books, hardcover brochures, business notebooks, and other books that need to be spread out for reading or display are required to be spread out 180 degrees. Ordinary back glue often […]
Acrylic panels can be usedhot melt adhesive pelletsIs it sticky? Acrylic (PMMA) has extremely low surface energy and is widely recognized as a difficult to stick material. But by selecting the right type of hot melt adhesive particles and combining them with the correct surface treatment, it is entirely possible to achieve a firm bonding. […]
Direct answer: For adhesive PP woven bags, APAO or POE based ones should be preferredHot melt adhesive pelletsDo not use regular EVA. The reason is that PP belongs to low surface energy materials (about 30 mN/m), and the EVA adhesive layer is almost unable to effectively wet it. When it sticks on, it does not […]
