Disclosure of Invention
The utility model mainly solves the technical problem of providing the puncture-resistant BOPP film structure, which not only has good puncture resistance, but also has low friction, smoothness and high strength treatment, is suitable for modern rapid automatic packaging, effectively solves the problem of packaging bag breakage, and can be used for packaging heavy objects and hard objects.
In order to solve the technical problems, the utility model adopts a technical scheme that: the puncture-resistant BOPP film structure comprises an anti-adhesion layer, a first adhesive layer, a core layer, a second adhesive layer and a puncture-resistant layer which are sequentially arranged in a coextrusion mode, wherein the total thickness of the film structure is 18-28 um, the thickness of the anti-adhesion layer is 5-10% of the thickness of the film, the thickness of the core layer is 75-80% of the thickness of the film, and the thickness of the puncture-resistant layer is 10-15% of the thickness of the film.
Preferably, the anti-blocking layer consists of homo-polypropylene and an anti-blocking masterbatch.
Preferably, the anti-sticking masterbatch consists of silica and homo-polypropylene.
Preferably, the core layer is composed of homo-polypropylene, erucamide slipping agent and SBS styrene thermoplastic elastomer.
Preferably, the first adhesive layer and the second adhesive layer are both composed of copolymerized polypropylene and polyethylene.
Preferably, the puncture resistant layer consists of polyamide.
The beneficial effects of the utility model are as follows:
the puncture-resistant film product prepared by the method has the puncture resistance of more than 30N, the dynamic friction coefficient of less than 0.30, the performance of which is superior to that of the existing BOPP film with the thickness of 20um, the puncture resistance of less than 15N and the friction coefficient of more than 0.40, and the BOPP film provided by the utility model not only has good puncture resistance, but also has low friction, smoothness and high treatment strength, can adapt to modern rapid automatic packaging, can be used as a composite film substrate to prepare puncture-resistant composite film packaging so as to solve the problem of package bag breakage, can be used for heavy object and hard object packaging, and has good technical popularization value.
