Buying hot melt adhesive granules should not only be based on price and color, but also on a set of feasible methods. We compared and evaluated the new material particles and miscellaneous materials from five dimensions, and the conclusion is very intuitive.
| Dimension | Good particles | Poor particles |
|---|---|---|
| Appearance | Uniform particles, no dust agglomeration | Different sizes, with debris |
| odor | Melting only has a light wax smell | Pungent and sour |
| Melting state | Good liquidity and no bubbles | Bubbling and poor wire drawing |
| bonding | The spine/box is securely fastened | Easy to fake, stick, and drop pages |
| Batch difference | Consistent across different batches | Stick today, don’t stick tomorrow |
On the same glue assembly line, the mixed brand particles are unevenly brushed at 180 ℃, and there are blank glue channels on the spine of the book; Sunlife hot melt adhesive particles penetrate evenly at the same temperature, and the book cannot be spread flat without shedding pages. The unit costs of the two are not significantly different, but there is a slight difference in yield.
Question: Is it better if the color is whiter?
Answer: No, the color depends on the formula, and the key is the melting and bonding performance.
Q: How to conduct initial screening without instruments?
Answer: Take a small amount of melted material, smell it, observe the bubbles, and test the adhesion on the machine. With three steps, 80% of the inferior materials can be eliminated.
Question: Are good particles necessarily expensive?
Answer: Not necessarily. Sunlife hot melt adhesive achieves high yield by relying on a stable formula, which is more cost-effective overall.
If you’re not sure, you need a sample first. Sunlife Hot Melt Adhesive from Guangzhou Sunlife Trading supports small sample machine comparison and evaluation.
There is currently no single “universal national standard” for hot melt adhesive granules, but ratherProduct standards+method standards+safety and environmental protection standardsThe three types of documents together constitute the basis for acceptance. What the purchaser needs to master the most is which standard corresponds to each of the four indicators of softening point, melt viscosity, peel […]
Paper straw roll adhesive selectionSpecially designed to meet food contact requirements, with fast initial adhesion and low odorHot melt adhesive pelletsThe straw rolling line has a fast speed, narrow overlap surface, and the glue must grasp the paper tape within 1 second. At the same time, it can withstand the low temperature and long-term soaking […]
Conclusion first:For printing factories with monthly usage of less than 2 tons and multiple machines for dispersed use, 25kg bags are more cost-effective; Packaging factories with stable monthly usage exceeding 3 tons and centralized feeding conditions have lower unit prices and more labor-saving for ton bags (500-1000kg bags).The price difference between the two is usually […]
Matching principle in one sentence:The faster the machine speed, the faster the required curing and the shorter the opening time; If the machine speed is slow or the workpiece is large and needs to be aligned over a long distance, it should be fixed and opened slowly insteadChoosing the wrong direction is either due to […]
