Abstract

PURPOSE:To obtain the titled film inexpensively by simple equipment, by pressure-laminating a polyolefin onto one surface of a film having arbitrary through- holes, metallizing the assemblage on the side of the film and then releasing the film from the laminate layer. CONSTITUTION:A polyolefin is pressure-laminated onto the surface of a film or sheet material 1 having arbitrary through-holes 2 to form a laminate film layer 3 releasably attached thereto. Then, this assemblage is metallized with Al or the like on the side of the film or sheet. Then, this film or sheet material 1 is released from the laminate film layer 3 to form partially metallized areas 4. If necessary, a top coat layer 5 is applied to protect the metallized areas 4 which are partially applied on the laminate film surface.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a partially metal-plated film in which a metal such as aluminum is partially vacuum-deposited on a plastic film such as polyolefin.

Conventionally, metal vacuum deposition technology has been widely applied to various plastic films and processed papers.
It is used in large quantities for various purposes.

Then, partial gold-paste vaporized sheets on which gold-paste evaporation was applied to parts of this gold-paste evaporated body are now on the market, and the field of application of gold-paste products is expanding1-. .

By the way, conventional methods for manufacturing bamboo sheets include the transfer method, which obtains partial vapor deposition by once vapor-depositing and then rolling it, and the hollow-scrumping force method. Coating a resin film on the surface by printing method etc. 1
-5 Tadaage Vermilion Painting - So-called 1 degree scouring in which the 1st part is decomposed with caustic soda etc.], etc. are known. Only +-
After going through a two-stage process, the first part was made (14)
Since it is a method of obtaining ', the production cost is high, and the equipment cost is also relatively high.

According to the invention disclosed in Publication No. 5,614,745, which solves the above-mentioned drawbacks, a punched sheet in which a continuous pattern is punched from TJ and a strong punched regular sheet are respectively prepared.

A method is disclosed in which the continuous IJH is advanced while overlapping the entire center of the sheet, and each of the strips is simultaneously VC-deposited from the side of the superimposed punched sheet, but in this method, the superimposed punched sheet and the regular sheet are After being unwound from the output roll, the ridges are vapor-deposited from the surface of the punched sheet by a metal evaporation source while passing through the lower part of the cooling drum, and the punched sheet and the regular sheet are separately wound by two winding rolls. The disadvantage is that misalignment easily occurs between the punched sheet superimposed on the sheet and the regular sheet from unwinding of the regular sheet to the first winding stage after metal deposition, making it difficult to form a predetermined gold-N deposited pattern. be.

Furthermore, in terms of equipment, it is undeniable that the scale of the vapor deposition machine becomes extremely large because two winding rolls are required to wind up the punched sheet and the regular sheet separately.

The invention has been made to solve the above-mentioned problems, and the structure thereof will be explained below with reference to the accompanying drawings.

In the drawings, reference numeral (1) indicates a film or sheet material having arbitrary through holes (2), and on this moon surface, polyolefin is extruded and laminated to form a laminate film 1-W.

Next, the film Mata d Sea! Apply P11 vapor deposition (4) of aluminum, etc. to the exposed side.

Next, the film or sealant (1) and laminate film! -M When (3) is peeled off, the surface of the laminate film is partially oxidized, resulting in Ruko7Vc.

3t! Laminate fill if necessary!・To protect the shoulder (4) partially provided on the surface.
゛Top-to-1 layer (5) is provided.

Coco'r any 75! Films or sheets with holes can be used, such as lace, woven fabrics, various patterns, etc.
Any VC such as plastic fillo or paper with cutouts
You can choose M.

In addition, as a means to releasably form a polyolefin laminate film layer on one side of the film or sheet having arbitrary through holes, extrusion lamination may be carried out at a polyolefin extrusion temperature lower than the normal extrusion temperature, or After performing a mold release treatment on the surface of the film or sheet using a silicone cocoon molding agent or the like, a polyolefin is laminated at a normal punching temperature.

Next, an uninvented embodiment will be described.

Example: As a sheet material having arbitrary through holes, polypropylene (d = 0.
9. A base material for vapor deposition was obtained by melt-extruding M (80) at 280°C and laminating a 50μ thick polypropylene film between nip rolls having a gap of 100μ.

Next, after vacuum-depositing Delminiram on the side of the split fiber nonwoven fabric of the substrate for vapor deposition, the polypropylene film and the vapor deposition base I are peeled off and wound together, and the split fiber nonwoven fabric is placed on the polypropylene surface. Aluminum in the same shape as the through hole!・The application was completed and the session was completed beautifully! f

As mentioned above, non-invention is constituted.

One laminated film cast on the filter sheet (11) with arbitrary through-holes is 9 (1 roll of laminate film 1-1-1-y"c) having an arbitrary perforation. When applying gold vaporization from the film or sheet application side, when unwinding it, and during the subsequent gold vapor deposition, there is a gap between the film or sheet main layer 4/. Since no misalignment occurs, partial vapor deposition having the same shape as any through hole provided in the film or sheet Vc can be uniformly formed.

Me, after the prescribed Gold Fi1 Reh H, the evidence of the Filno or Seat and Ramio, -Top Irum JF4 is 0-1 and 7< *JJ 閘posflF! , η are in an assortment, so it is not necessary to wind them separately, but it is possible to wind them separately after winding them, and the workability is extremely good.

J! As an apparatus to be used in the uninvented implementation, it is possible to implement the method using a conventional device since it only requires one unwinding roll and one take-up roll in the above-mentioned dotoku metal evaporation apparatus.
