The present invention is a kind of tool magnetic APET compound film, this APET compound film comprises top layer and nexine, described nexine adopts coating processes to take shape in the inner side on top layer, described top layer is APET sheet material, described nexine is magnetic functional layer, and the main component of described nexine raw material is: magnetic particle, synthetic resin, solvent and related auxiliaries.
In a preferred embodiment of the present invention, described magnetic particle selects permanent magnetism particulate, and its average particulate diameter is about 5-7um.
In a preferred embodiment of the present invention, the raw material of described synthetic resin is LDPE powder.
In a preferred embodiment of the present invention, described solvent selects toluene or dimethylbenzene.
In a preferred embodiment of the present invention, described auxiliary agent comprises dispersant, heat stabilizer, lubricant and flexibilizer etc.
In a preferred embodiment of the present invention, the molding thickness of described nexine controls at 0.12-0.14mm.
Present invention is disclosed a kind of tool magnetic APET compound film, this compound adhesive chip architecture is reasonable in design, effect is unique, the good combination property of APET film has been acted on its top layer, nexine then imparts the magnetic adsorption capacity of APET sizing material uniqueness, makes this compound film have the functional and practicality of more horn of plenty when using as external packing.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
