New description: [New technical field] This creation is related to a plastic The outer film of the thin-shell composite, in particular, an outer decorative layer, an intermediate adsorption heat-insulating layer and an inner adhesive layer are sequentially laminated to form a thin film which can be placed in a molding die. A plastic thin shell member is injection molded on the inner adhesive layer to form a plastic thin shell member composite having good adhesion. [Prior Art] Various electronic products on the market are described here as but not limited to electronic products, including common computer products such as notebook computers (nb) and communication products. For example, 3C products such as mobile phones or consumer products are not limited, and a thin shell member is often used as the outer casing of the product; the thin shell member has different structures according to the design requirements of the product, and if the thin shell member body of the outer shell is used ( Base) The material used can be divided into two main structural categories: plastic® thin shell and thin metal shell. A plastic thin-shell member having an outer decorative surface is generally formed by an in-mold decorating process (IMD), which is a carrier that forms a two-dimensional shape and is printed with a pattern ( Substrate) such as a plastic film, hereinafter referred to as an IMD film, is embedded in a molding die, and then a plastic injection molding technique is used to project a hot melt resin on the back side of the IMD film to form a substrate of the casing. Hereinafter, a resin matrix is used to bond the resin matrix and the IMD film to form an integral plastic thin shell member, wherein the IMD film can be fixedly bonded to the outer surface of the resin base.
