Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The stretch-proof composite sheet suitable for wrapping electronic products as shown in fig. 1 to 4 comprises a composite sheet body, and is distinguished in that: the bottom layer of the composite sheet body forms a PET substrate layer 1, a filling adhesive layer 2 is distributed on the PET substrate layer 1, and a PE film layer 3 is laid on the filling adhesive layer 2. Therefore, the PET substrate layer 1 and the PE film layer 3 are bonded into a whole, and the anti-tearing PET substrate layer has a good anti-tearing effect. Meanwhile, in consideration of the antistatic requirement of the electronic product package, an auxiliary laminating layer 4 is paved on the PE film layer 3, and an antistatic adhesive film 5 is arranged on the auxiliary laminating layer 4. Certainly, for some special applications, hot-pressing equipment can be directly adopted to realize glue-free hot-pressing combination without the need of the auxiliary laminating layer 4. In order to achieve effective filling of the filling adhesive layer 2, the upper surface of the PET substrate layer 1 and the lower surface of the PE film layer 3 are provided with a plurality of sol grooves 6. In this way, a part of the filled adhesive layer 2 can enter the sol bath 6 efficiently during the preparation extrusion, achieving a better adhesion and ensuring that no separation occurs during the application of force. Furthermore, in order to have the integrity of the formed film and avoid unnecessary tearing when the edge part is subjected to pulling stress, the edge of the composite sheet body is coated with a PP edge sealing film 7.

In accordance with a preferred embodiment of the present invention, the thickness of the PET substrate layer 1 is 0.3 to 0.8 mm. The thickness of the PE film layer 3 is 0.2 to 0.6 mm. The thickness of the filling adhesive layer 2 and the auxiliary adhesive layer 4 is 0.2 to 0.3 mm. The thickness of the antistatic adhesive film 5 is 0.3 to 0.6 mm.

Meanwhile, the thickness of the adopted PET substrate layer 1 is 0.5 mm according to the package requirement of a conventional PCB such as a blank PCB or a PCB provided with components. The thickness of the PE film layer 3 is 0.45 mm. The thickness of the filling adhesive layer 2 and the auxiliary adhesive layer 4 is 0.5 mm. The thickness of the antistatic adhesive film 5 is 0.4 mm. Therefore, during the process of meeting the requirements of anti-static and waterproof obstruction wrapping, the pulling force given by the packaging machine can be adapted, and the tearing can not occur.

Furthermore, in order to achieve effective bonding without adding excessive extra thickness, the filling adhesive layer 2 and the auxiliary adhesive layer 4 are both resin adhesive layers. Thus, it has proper adhesion and certain pulling resistance.

In view of practical implementation, considering that different electronic products are actually wrapped, in order to have a better anti-static effect and prevent some precise components or circuits from being accidentally broken down, the anti-static adhesive film 5 is one of a polyurethane film, a polyethylene film, a polyester resin film and a semi-aluminized electronic film.
