Description

A kind of heat discoloration metallized film
Technical field
The present invention relates to vacuum aluminum-coated field more particularly to a kind of heat discoloration metallized films.
Background technique
Aluminizer is that the aluminium wire of high-purity is flashed to gaseous state at high temperature by vacuum aluminium plating process, later plastic film When by being evaporated in vacuo room, gaseous aluminium molecule is deposited to Plastic film surface and the film of bright metal color that is formed.
The introducing of vacuum plated aluminum film is by aluminium foil.The aluminium foil used on flexible packaging, generally in 6~20 μ m thicks Between.Aluminium foil has silvery white gloss, and transparent ink is directly printed on aluminium foil, can there is peculiar metallic luster.Aluminium foil has good Light-proofness well, gas barrier property, resistance are moist, there is good thermal conductivity, electromagnetic wave shielding.It is wherein the barrier property of aluminium foil to dash forward, Under the premise of aluminum foil thickness is enough, gas and moisture can be obstructed completely, thus in flexible packaging base material film, aluminium foil is not Can or scarce material, be widely used in Key works Drug packing, food packaging, relatively in particular for thermophilic digestion and holding time In the flexible package of the expensive goods such as long drug, cosmetics.
But after aluminium foil has a fatal defect-bending, aluminium foil is easy to crack, and influences the barrier property of aluminium foil, Aluminium foil price is more expensive simultaneously.In the eighties in last century, a kind of new technology-is vacuum aluminum-coated to be introduced into.Hereafter, more and more people Start under the premise of not influencing quality requirement, vacuum plated aluminum film is used instead to replace aluminium foil, to reduce packing cost.
The present invention provides a kind of heat discoloration metallized film, can play the role of reminder alarm with temperature transition color, will It is used widely in fields such as anti-fake, cosmetics, toys.
Summary of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of heat discoloration metallized film.
The present invention is realized with following technical solution:
A kind of heat discoloration metallized film, the film include substrate, and corona layer, release is sequentially coated on the substrate Layer, heat discoloration layer, aluminium coated and gum layer.
Further, the substrate includes but is not limited to cast polypropylene (VMCPP), polypropylene screen (CPP, BOPP, IPP), polyester film (PET), PA membrane (PA), polyethylene film (PE), glassine paper (PT).
Further, the release layer is resin layer, is applied directly on substrate.
Further, the release layer has the hot characteristic of high temperature resistant, and can protect heat discoloration layer not by extraneous ring The erosion in border, while there is fissility.
Further, the concentration for changing resin in release layer raw material can change its peel strength.
Further, the heat discoloration layer is mixed by heat discoloration paint and acroleic acid resin.
Further, the corona layer is made of acrylic polymer and guar gum blend, is coated on temperature-sensitive Change colour layer surface, the acrylic polymer optimal ethylene methylmethacrylate copolymer.
Further, the aluminium coated is attached to corona layer surface, is that heating evaporation aluminium wire is allowed to gas under vacuum conditions Change, the surface for being then attached to corona layer is formed.
Further, the gum layer is made of bonding agent, by net roll by adhesive-coated in the surface of aluminium coated, warp It crosses baking oven high-temperature process and is formed after drying.
The beneficial effects of the present invention are:
1) heat discoloration new material is creatively introduced into metallized film by the present invention, changes color with temperature using it Characteristic plays decoration, instruction or warning function, and product need to only change temperature with temperature or artificially, just obtains several different face Color enriches color category, increases the industrial feasibility of product.
2) present invention utilizes the characteristic of acrylic polymer and guar gum blend, Lai Tigao aluminium layer and polyacrylic Adhesion strength, and achieve the effect that the adhesive force for improving aluminium coated.Esters of acrylic acid adds guar polymer to have with polypropylene Good miscibility will not influence the physical property of film, and can enhance aluminium coated and the polyacrylic adhesive force of corona layer.This hair Bright metallized film produced, aluminium coated adhesive force testing result is all larger than 2.5N/15mm, and common metallized film aluminium coated is attached Put forth effort testing result maximum and there was only 0.6N/15mm.
