Embodiment 1

[0027] Such as figure 1 As shown, the BOPP extrusion coating film includes a functional layer 1, a core layer 2, and a secondary functional layer 3. The core layer 2 is located between the functional layer 1 and the secondary functional layer 3. The functional layer 1, the core layer 2, and the secondary functional layer Layer 3 is integrated by biaxial stretching after co-extrusion; the mass percentages of the material of the functional layer, the material of the core layer, and the material of the sub-functional layer are: 5% of the functional layer, 90% of the core layer, and 5% of the sub-functional layer %;

[0028] The material of the functional layer is composed of acrylic resin (Mitsubishi acrylic resin BR-116 product description: brand: Mitsubishi, model: BR-116, origin: Japan), block copolymerized polypropylene, C9 hydrogenated petroleum resin (or C9 plus hydrogenated petroleum resin, hydrogenated C9 petroleum resin), antioxidant, and dispersant, and the mass percen...

Embodiment 2

[0058] Such as figure 1 As shown, the BOPP extrusion coating film includes a functional layer 1, a core layer 2, and a secondary functional layer 3. The core layer 2 is located between the functional layer 1 and the secondary functional layer 3. The functional layer 1, the core layer 2, and the secondary functional layer Layer 3 is integrated by biaxial stretching after co-extrusion; the mass percentages of the material of the functional layer, the material of the core layer, and the material of the sub-functional layer are: 10% of the functional layer, 80% of the core layer, and 10% of the sub-functional layer %;

[0059] The material of the functional layer is composed of acrylic resin (Mitsubishi acrylic resin BR-116 product description: brand: Mitsubishi, model: BR-116, origin: Japan), block copolymerized polypropylene, C9 hydrogenated petroleum resin (or C9 plus hydrogenated petroleum resin, hydrogenated C9 petroleum resin), antioxidant and dispersant, the mass percentag...

Embodiment 3

[0073] Such as figure 1 As shown, the BOPP extrusion coating film includes a functional layer 1, a core layer 2, and a secondary functional layer 3. The core layer 2 is located between the functional layer 1 and the secondary functional layer 3. The functional layer 1, the core layer 2, and the secondary functional layer Layer 3 is integrated by biaxial stretching after co-extrusion; the mass percentages of the material of the functional layer, the material of the core layer, and the material of the sub-functional layer are: 20% of the functional layer, 60% of the core layer, and 20% of the sub-functional layer %;

[0074] The material of the functional layer is composed of acrylic resin (Mitsubishi acrylic resin BR-116 product description: brand: Mitsubishi, model: BR-116, origin: Japan), block copolymerized polypropylene, C9 hydrogenated petroleum resin (or C9 plus hydrogenated petroleum resin, hydrogenated C9 petroleum resin), antioxidant and dispersant, the mass percentag...

Abstract

The invention belongs to the technical field of label materials, and particularly relates to a coating membrane of labels for personal care products, beer, cosmetics, beverages, electronic products, toys and the like. A BOPP (biaxially-oriented polypropylene) extrusion coating membrane is characterized by comprising a functional layer, a core layer and a secondary functional layer; the core layer is positioned between the functional layer and the secondary functional layer; the functional layer, the core layer and the secondary functional layer are subjected to coextrusion, then are stretched bidirectionally, so as to form an integrated body; materials for preparing the functional layer, the core layer and the secondary functional layer respectively account for 5-20%of the total weight, 60-90%of the total weight, and 5-20% of the total weight; the materials for preparing the functional layer are prepared by mixing acrylic-modified polyethylene, blocked copolymerized polypropylene, C9 hydrogenated petroleum resin, an antioxidant and a dispersion agent; the acrylic modified polyethylene accounts for 30-60% of the total weight, the blocked copolymerized polypropylene accounts for 30-45% of the total weight, the C9 hydrogenated petroleum resin accounts for 7-20% of the total weight, the antioxidant accounts for1-3% of the total weight and the dispersion agent accounts for1-2%of the total weight. The BOPP extrusion coating membrane provided by the invention has the characteristics of low cost, good printing firmness and good wiping resistance.

Description

technical field [0001] The invention belongs to the technical field of label materials, and in particular relates to a coating film used for labels of daily chemicals, beer, cosmetics, beverages, electronic products, toys and the like. Background technique [0002] B0PP coating film is used for labels of daily chemicals, beer, cosmetics, beverages, electronic products, toys, etc. The existing labels are coated with a functional layer off-line by B0PP, but the disadvantages are: high cost and poor printing fastness , Poor wiping resistance, poor printing quality of UV ink flexo, letterpress and screen.
