Embodiment 1

[0016] See attached figure 1 , 2 , 3, at first imitation metal film is processed, add 1.5Kg1702B sizing material by 0.035Kg yellow pigment and add 1Kg ethyl acetate solvent dilution and mix as printing pigment, carry out screen printing on the single side of film 5, form printing layer 4 , as a colored substrate, the printed layer 4 of the colored substrate is vacuum-plated at 1400°C to form a metal-like film, and then coated with butanone solvent on the surface of the vacuum-coated aluminum layer 3 of the metal-like film. A-969V is compounded with A-5 adhesive 2 and substrate 1, dried in a drying room 6 at a temperature of 80°C, and compounded into a composite imitation metal sheet, which is cured at a temperature of 60°C and cut into coils , inspection, storage.

Embodiment 2

[0018] Firstly, process the imitation metal film, dilute and mix 0.035Kg yellow pigment plus 1.5Kg LY-7328 and LY-7328H glue plus 1Kg butyl acetate solvent as printing pigment, and screen print on one side of the plastic film. Form the printing layer 4, as a colored substrate, on the printing layer 4 surface of the colored substrate, carry out vacuum aluminum plating at 1400 ° C to form a metal imitation film, and then on the surface of the vacuum aluminum plating layer 3 of the imitation metal film and Squeeze the adhesive 2 between the substrates 1 for compounding. The adhesives are A3230 and I3000, which are dried in a drying room 6 at a temperature of 80°C, and compounded into a composite imitation metal sheet, and then cured at a temperature of 60°C. , cut into rolls, and then cold processed, using the method of stamping, made into folding boxes, inspected, and put into storage.

Embodiment 3

[0020] Firstly, the imitation metal film is processed, and after 0.035Kg yellow pigment plus 1.5Kg acrylic varnish sizing material is diluted and mixed with 1Kg ethanol solvent, it is used as a printing pigment, and screen printing is carried out on one side of the plastic film to form a printing layer 4. Substrate, on the printed layer 4 of the colored substrate, carry out vacuum aluminum plating at 1400 ° C to form a metal imitation film, and then coat the surface of the vacuum aluminum plating layer 3 of the imitation metal film with cyclohexanone solvent to dilute and bond Agent 2 is used to bond the substrate 1 for compounding. The adhesive is cured at 60°C with A-626 and A11, and compounded into a composite imitation metal sheet, which is cut into coils and then thermally processed. Under hot pressing, it is made into a food tray, inspected, and put into storage.

Abstract

Disclosed is a composite imitation metal sheet (coiled) material and production method thereof. The material comprising a plastic film layer and an aluminized layer is characterized in that it also comprises a printed layer, an adhesive and a substrate, wherein the layers are arranged in the following sequence: the plastic film layer, the printed layer, the aluminized layer, the adhesive and substrate, and the printed layer and aluminized layer are wrapped between the substrate and the plastic film layer. The beneficial effects of the invention are: the material will not pollute the packaged articles or foodstuff, and can be processed by cold punching or heat forming to produce foodstuff trays or craftworks with different shapes.

Description

1. Technical field: [0001] The invention relates to a coil material, in particular discloses a composite imitation metal sheet (coil) material and its production process, which is applied to the packaging of food and craft gifts. 2. Background technology: [0002] The aluminized plastic sheet used for product packaging in the existing market has an aluminized layer that falls on one side of the sheet. The main materials used are colored PVC, PET and BOPS, which are aluminized on one side, and then made into packaging products. Applied to food, such as moon cake trays, chocolate trays, crafts and gifts and other packaging tray products, the surface of the material, because the aluminum layer is easy to fall off and the surface of the colored plastic film is easy to decolorize, it is easy to contaminate food and other packaged products, especially In terms of food packaging, it does not meet the food hygiene requirements. 3. Contents of the invention: [0003] The technical...
