Legitimate hot melt adhesive particles themselves are thermoplastic polymers that are solid, non-volatile, and insoluble in water at room temperature, making them relatively safe adhesive materials. Whether it is “toxic” mainly depends on the formula and high-temperature usage method.
| focus | Explanation |
|---|---|
| recyclability | Pure EVA hot melt adhesive belongs to thermoplastic and can theoretically undergo further hot melt treatment |
| Residual odor | After cooling, the odor is sealed, and there is almost no sensation when it comes to books/boxes |
| Inspection Report | Choose a manufacturer that can provide RoHS and VOC data |
Q: Can hot melt adhesive particles come into contact with food packaging?
Answer: It is necessary to choose a food grade formula and provide contact safety testing. Sunlife hot melt adhesive can provide corresponding reports according to its use.
Q: Does having a smell equate to being toxic?
Answer: Not necessarily, but a pungent smell usually means there are more volatile substances. It is recommended to replace it with qualified materials.
Q: How can the workshop reduce risks?
Answer: Temperature control should not exceed the upper limit, ventilation should be maintained, and low odor new material particles should be selected.
Sunlife hot melt adhesive from Guangzhou Sunlife Trading can provide environmental and food contact testing reports, making procurement more reassuring.
The desk calendar is a hard demand for graphic and text fast printing stores during the peak season every year. The binding methods are divided into circle binding, glue binding, and loose leaf binding, with significant differences in corresponding glue particles. We conducted a horizontal evaluation of three mainstream adhesive particles, Sunlife Hot Melt Adhesive, […]
The characteristics of EVA hot melt adhesive: Hot melt adhesive is a solid, fusible polymer that does not require solvents and contains no 100% moisture. It is solid at room temperature and turns into fluid and viscous liquid when heated to a certain temperature. Melted EVA hot melt adhesive is light brown or white. EVA […]
Where does batch color difference come from? hot melt adhesive pelletsThe color depends on the natural color of the EVA resin batch, the type of tackifying resin, the whiteness of the filler, and the amount of coloring agent added. Small fluctuations in each batch of raw materials can lead to color differences in the finished […]
Directly speaking, the method is to seal the box in winter without bursting, relying on three things: “low-temperature glue+temperature control+coating amount” In winter, when express cardboard boxes burst and open, it is mostly not due to poor quality of the glue, but rather the fact that the sealing glue that works well at room temperature […]
