Curing conditions of PE protective film

- Sep 07, 2020-

First of all, when it comes to PE protective film, with regard to its curing, to a large extent, it will actually be called curing. In this regard, in fact, it should be noted that it should be composited. The film is placed in the drying room (curing room). In view of this, to a large extent, it will directly cause the main agent or curing agent of the polyurethane adhesive to react and crosslink and be composited by the substrate. The process of surface interaction.

In view of this, when it comes to the curing conditions of PE protective film, to a large extent, it is actually directly dependent on some factors, such as PET, BOPA, AL, CPP and other films. In fact, it is because its heat resistance is better. Next, we actually need to pay attention to its own shrinkage temperature, which is higher. In this way, we actually need to pay attention to It can also increase its curing temperature.

However, for the curing temperature of LDPE, BOPP, EVA, etc., to a large extent, it should not be too high; then, the curing time of products with high glue amount will be longer. ; The maturation time of products shipped in the form of protective film rolls can be appropriately reduced.

In terms of another aspect, we actually need to pay attention to the fact that products with longitudinal ribs can have a longer curing time; then, when the film thickness and film roll diameter are relatively large, To a large extent, it can actually extend its own ripening time.

Finally, when it comes to the curing conditions of the PE protective film, to a large extent, it is actually to reduce the amount of residual solvent. In this way, to a large extent, it can actually be extended appropriately. It has its own maturation time; of course, because of this, we actually have to pay attention to the direct adjustment of its own maturation time based on the use of the protective film product.
