The storage method of hot melt adhesive particles after opening directly determines whether they can still be used and whether they stick firmly. We took the same batch of Sunlife hot melt adhesive particles and stored them in three different ways for one month. We compared the moisture, clumping, and bonding performance, and the results were very intuitive.
| way | Operation | Status after one month | Adhesive performance |
|---|---|---|---|
| Open stacking | Remove the bag without sealing it and place it on the ground | Moisture absorption, clumping, and bubbles | Obvious discount, easy to fake and stick |
| Sealed and cool | Tighten the inner bag, elevate the pallet, and avoid light | Dry and free from lumps | Almost no attenuation |
| The original package has not been opened | Whole box sealed inventory | Intact as new | best |
The open stacked particles are filled with bubbles after melting, and the spine of the book is unevenly brushed; The difference between the sealed cool group and the unopened group is minimal. It is not the act of “opening” that determines lifespan, but ratherMoisture and heat resistanceHas it been done properly. Sunlife hot melt adhesive from Guangzhou Sunlife Trading has good sealing performance in its original packaging. As long as the seal is restored in a timely manner after material collection, it can be stored for 3-6 months without any problems.
