EVA eco-friendly hot melt adhesive is a thermoplastic material composed of EVA, tackifiers such as petroleum and rosin, as well as some bonding AIDS, and is formed in solid cylindrical rods or granular form. It can be melted and applied by using a hot melt gun, sprayer or other glue binding equipment, etc.
Because it contains no solvents, hot melt adhesive does not cause pollution and has a very small impact on the environment. It can even be said to be pollution-free! The use of Sunlife hot melt adhesive particles is different from other solvent-based adhesives. It does not require any special ventilation and there are no concerns about flammability or other aspects.
Due to its affordable price, this environmentally friendly adhesive has been adopted not only in the printing industry such as bookbinding but also in large-scale packaging operations in the construction industry. This is the reason why governments, regulatory agencies and even environmental protection organizations all support the use of hot melt adhesives on solvent-based adhesives.
Ethylene-vinyl acetate (EVA) is a commonly used eco-friendly hot melt adhesive due to its versatility. Manufacturers can easily control the viscosity and stickiness of hot melt adhesive particles by regulating plasticizers (wax or oil), so it can be used in various dispensers, industries and applications. It is expected that EVA will continue to occupy a large share of the hot melt adhesive market. At the same time, it is also an environmentally friendly non-solvent-based adhesive.
If, like many manufacturers, hot melt adhesive on the packaging line may encounter problems, resulting in slower packaging speed, increased costs, and potential product damage or loss. Let’s take a look at the common hot melt adhesive problems that manufacturers face today and explore possible solutions. Problem 1: UsingHot melt adhesiveToo little If your packaging […]
Using hot melt adhesive particles on the same material surface will provide better quality assurance, as hot melt adhesive is always sprayed on the material surface in a molten state – this helps to generate thermal reactions and increases adhesion compared to adhesives, without using heat during the bonding process. Stable quality provides good adhesion […]
There are three commonly used testing methods for the peel strength of hot melt adhesive particles:180 ° peel off(Soft substrate to soft substrate, such as laminated paper, non-woven fabric)90 ° peeling(Soft substrate to hard substrate, such as cardboard bonding) andT-shaped peeling(Used when the flexibility of the substrate on both sides is similar). The most commonly […]
On bound bookshot melt adhesiveTo remove it, the correct approach isFirst, control the temperature to soften, then mechanically separate, and finally clean the residual glueUsing a mild heat source of 60-80 ℃ to soften the adhesive layer and peel it off as a whole is more secure than any forced tearing or chemical pesticides. Unfortunately, […]
