Problems solved by technology

[0002] Polyethylene has been widely used in various fields. It is a general-purpose thermoplastic material with excellent transparency and rigidity. It has good moldability, but its poor impact resistance limits its application.
As we all know, rubber or thermoplastic elastomers are usually added to improve the impact resistance of polystyrene. In this way, although its impact resistance can be improved, its surface properties are not ideal and easy to scratch, especially when used in electronic product packaging. During the transportation of the electronic product, due to the friction between the packaging material and the product, the surface of the packaging material is de-powdered, and the powder adheres to the surface of the product, resulting in poor appearance of the product

Embodiment Construction

[0008] see figure 1 , shows the first preferred embodiment of the polystyrene plastic sheet of the present invention, the polystyrene plastic sheet 10 includes a first polyethylene layer 101 and a polystyrene layer 102 . The polyethylene layer 101 has a thickness of 0.1 mm, the polystyrene layer 102 has a thickness of 0.9 mm, and the polyethylene layer 101 is disposed on the first surface 1022 of the polystyrene layer 102 .

[0009] It can be understood that the thickness of the first polyethylene layer 101 is not limited to 0.1 mm, the thickness of the first polyethylene layer 101 is from the minimum thickness that can play a wear-resistant role and can fully adhere to the polystyrene layer 102 The maximum thickness without falling off is defined. The minimum thickness of the first polyethylene layer 101 that can play a wear-resistant role is generally 0.05 mm, and the maximum thickness of the first polyethylene layer 101 that can fully adhere to the polystyrene layer 102 is...

Abstract

The invention provides a polystyrene plastic sheet, comprising a polystyrene layer and a first polyethylene layer. The first polyethylene layer is arranged on a first surface of the polyethylene layer with the thickness ranging from the minimum thickness by which the polyethylene layer can have wearable function and the maximum thickness by which the polyethylene layer can be sufficiently attached to the polystyrene layer and does not drop off. By attaching the polyethylene layer to the polystyrene layer, and owning to the excellent wearable performance of the polyethylene, the invention further improves the wearable performance of the polystyrene plastic sheet, effectively prevents the powder-dropping phenomenon of the polystyrene plastic sheet, and does not affect the appearance of a packaged product.

Description

technical field [0001] The invention relates to a polystyrene plastic sheet. Background technique [0002] Polystyrene has been widely used in various fields. It is a general-purpose thermoplastic material with excellent transparency and rigidity. It has good moldability, but its poor impact resistance limits its application. As we all know, rubber or thermoplastic elastomers are usually added to improve the impact resistance of polystyrene. In this way, although its impact resistance can be improved, its surface properties are not ideal and easy to scratch, especially when used in electronic product packaging. During the transportation of the electronic product, due to the friction between the packaging material and the product, the surface of the packaging material is de-powdered, and the powder adheres to the surface of the product, resulting in poor appearance of the product. Contents of the invention [0003] In view of the above situation, it is necessary to provide...
