Food Bag Lift Rope Hot Melt Adhesive

                        Can hot melt glue stick with water?

Hot Melt Adhesive can be glued into two cases, one is water on the colloidal surface, the other is water on the surface of the adhesive, let's talk about whether hot melt adhesive can complete the bonding task in these two cases, and can stick well.
Will water on the surface of the colloid affect the bonding effect? The first thing to be explained here is that although the Binding Agent will come into contact with water during the production process, it must be dry before packaging, and there is no doubt that the water residue caused by the improper production of hot melt adhesive is. Before putting into the sol box or glue tank, it is necessary to ensure that the gel is dry, without a trace of moisture, why? Because the glue after melting into water has a certain consistency, although the water will be vaporized at high temperature, there is a high probability that bubbles will form in the glue, and when the bubbles flow out with the hose, the empty glue phenomenon will be formed in the glue layer, thus affecting the bonding effect and aesthetics. Therefore, the direct use of hot melt adhesive with water on the surface may affect the bonding effect.

There is water on the adhesive, will it also affect the bonding effect? It depends on the product. Because it is not that the product with water on the surface is not good, some products must first wet the substrate before they can be on the production line, which depends on the production process of the product. Under normal circumstances, the bonding surface of some products does not allow foreign bodies to affect bonding. If there is water between the adhesive layer and the substrate, how much will also have an impact on the bonding effect, unless it does not have much requirement for the bonding strength. It can be seen that if there is no need for water to be involved in the normal process, try to avoid wetting the adhesive.
See here, you should also understand the influence of water on hot melt glue, water does not necessarily affect the bonding effect, but the process is not necessary, it is recommended to avoid hot melt glue and water contact.
