Embodiment 1

[0023] Embodiment 1: as figure 1 As shown, the digital pre-coating film is composed of a substrate layer 1 and a hot melt adhesive layer. The substrate layer 1 and the hot melt adhesive layer 2 are combined together. The substrate layer is biaxially oriented polypropylene film (BOPP) or biaxially stretched Stretched polyester film (BOPET); the hot melt adhesive layer is a mixture of ethylene-vinyl acetate (EVA) and petroleum resin after coupling treatment.

[0024] The ethylene-vinyl acetate (EVA) and the petroleum resin of the hot-melt adhesive layer account for the weight percent example of the hot-melt adhesive layer respectively through the coupling treatment: the ethylene-vinyl acetate (EVA) through the coupling treatment is 92%, Petroleum resin is 8%. The coupling-treated ethylene-vinyl acetate (EVA) is formed by soaking ethylene-vinyl acetate (EVA) with 5% coupling agent and alcohol mixture, making it fully mixed and then drying. The coupling agent is a silane couplin...

Embodiment 2

[0030] Embodiment 2: digital pre-coating film, is made up of substrate layer and hot-melt adhesive layer, and substrate layer and hot-melt adhesive layer are compounded together, and substrate layer is biaxially stretched polypropylene film or biaxially stretched polyester film; The hot melt adhesive layer is a mixture of ethylene-vinyl acetate (EVA) and petroleum resin after coupling treatment.

[0031] The ethylene-vinyl acetate (EVA) of the coupling treatment of the hot melt adhesive layer and the petroleum resin account for the weight percent example of the hot melt adhesive layer respectively: the ethylene-vinyl acetate (EVA) of the coupling treatment is 94%, Petroleum resin is 6%. The coupling-treated ethylene-vinyl acetate (EVA) is formed by soaking ethylene-vinyl acetate (EVA) with 5% coupling agent and alcohol mixture, making it fully mixed and then drying. The coupling agent is a silane coupling agent, an epoxy coupling agent or an amino coupling agent. Wherein, th...

Embodiment 3

[0034]Embodiment 3: digital pre-coating film, is made up of substrate layer and hot-melt adhesive layer, and substrate layer and hot-melt adhesive layer are compounded together, and substrate layer is biaxially stretched polypropylene film or biaxially stretched polyester film; The hot melt adhesive layer is a mixture of ethylene-vinyl acetate (EVA) and petroleum resin after coupling treatment.

[0035] The ethylene-vinyl acetate (EVA) and the petroleum resin of the hot-melt adhesive layer account for the percentage by weight of the hot-melt adhesive layer respectively: the ethylene-vinyl acetate (EVA) through the coupling is 88%, Petroleum resin is 12%. The coupling-treated ethylene-vinyl acetate (EVA) is formed by soaking ethylene-vinyl acetate (EVA) with 5% coupling agent and alcohol mixture, making it fully mixed and then drying. The coupling agent is a silane coupling agent, an epoxy coupling agent or an amino coupling agent. Wherein, the VA content in ethylene-vinyl ac...

Abstract

The invention discloses a digital pre-laminating film which is characterized in that the digital pre-laminating film is composed of a base material layer and a hot melt adhesive layer, wherein the base material layer and the hot melt adhesive layer are compounded; the base material layer is a two-way stretch polypropylene film or a two-way stretch polyester film; the hot melt adhesive layer is the mixture of EVA processed in a coupling manner and petroleum resin in the following weight percent: 85-94% of EVA processed in a coupling manner and 6-15% of petroleum resin. After the invention uses a digital print surface, the print surface is smooth and light, thus greatly improving the glossiness and the fastness of the print, prolonging the service life of the product, and performing the protective functions of water prevention, pollution prevention, abrasion resistance, hard fold and the like. The print after being covered with film has vivid and beautiful appearance and is full of three-dimensional texture. The invention is suitable for heating mounting and laminating for advertising paper printing and the like for advertising spray painting, colour painting and the like and opens a new application field in the heating mounting and pre-laminating field.

Description

technical field [0001] The invention relates to a digital pre-coating film, which is compounded on the surface of paper printed matter and spray painting, and belongs to the technical field of paper-plastic heat-mounted composite film. Background technique [0002] The lamination of paper printed matter and spray painting is one of the processes in the post-press processing process. It refers to the paper printed matter and inkjet painting that are printed and bonded together with the adhesive-coated plastic film through the pressure of the rubber roller and the electric heating roller to form a paper-plastic product. After the paper printed matter is coated, a thin and transparent plastic film is added on the surface, and the surface of the printed matter appears smoother and brighter, which greatly improves the gloss and fastness of the printed matter, prolongs the service life of the product, and plays a waterproof, Anti-fouling, wear-resistant, folding-resistant and oth...
