The difference between hot melt adhesive film and hot melt adhesive mesh film, hot melt adhesive film mainly exists in two forms, namely hot melt adhesive film and hot melt adhesive mesh film, its use and performance are different.
1, breathability
The hot melt adhesive film melts the hot melt adhesive into a paper-like type with no gaps and good water repellency, while the hot melt mesh film is paper-like, but has a gap in the middle, similar to "silk". The connection is so that the hot melt web is more breathable.
2, stiffness
Based on the above, the stiffness of the hot melt adhesive film is conceivable, and its influence on the hardness of the cloth (or other material) after bonding is large, and the hot melt adhesive film is connected due to Not very tight, its effect on the fabric is slightly smaller than the film.
3, the degree of weight
The hot melt adhesive film and the mesh film are manufactured differently. Under the same size, since the mesh film is not closely connected, the weight thereof is lighter, and the hot melt adhesive film is heavier.
4, the difference in viscosity
According to the above situation, it is not difficult to see that the viscosity of the film is larger than that of the mesh film. The hot melt film is more firmly bonded and has higher peeling strength. Therefore, in the case where the gas permeability is not very high, the hot melt adhesive film is mainly used. For the bonding application, the hot melt film is mainly used for the opponent and the gas permeability.
