Film.
Background technology
Multilayer flexible packaging film is widely used in the packaging such as food, tealeaves, coffee.Fig. 1 is refer to, it illustrates known multilayer Soft Roll
Fill the diagrammatic cross-section of film construction.As illustrated, its basic construction is a refractory layer 500, a printing layer 510, a laminating layer
520 and a hot sealing layer 530.
Fig. 2 is refer to, it illustrates the diagrammatic cross-section of another known multilayer flexible packaging film construction.As illustrated, its is basic
Construction be a refractory layer 600, a printing layer 610, a laminating layer 620, a functional layer 625 and a hot sealing layer 630, wherein, should
Functional layer 525 can be the vapor barrier layers such as the aluminium foil that add of increase gas barrier performance or nylon EVOH, or other functions and increase
Film layer.
The hot sealing layer 630 is then to seal into the sack of all size.It is use such as PP, PE, EVA low melting point can heat more
Seal as hot sealing layer.The printing layer 610 is then subject to printing for heat-resisting materials such as BOPET, Nylon and formed.Wherein especially with BOPET films
Printed the most extensive as the printing layer 610.It is rather dull although beautiful to decorate with printing, so having in recent years
Printing is coordinated to make more in riotous profusion beautiful decorative layer with laser film (Holographic film).
Increase ornamental function as shown in WO 93/008084, but be in hot sealing layer and original disclosed in WO 93/008084
Separately add one layer of laser film between the printed decoration layer come.Fig. 3 is refer to, it illustrates institute in the accompanying drawing 1 of the patents of WO 93/008084
The diagrammatic cross-section of the multilayer flexible packaging film construction of announcement.As shown in figure 3, the laser film 700 is thermoplastic plastic's film, thereon
One layer of environment-friendly water-based coating is coated with, is formed through hot padding.
But the multilayer flexible packaging film made by method causes cost too high because laser film 700 is added according to this, except increase
Outside the cost of laser film 700, the cost being once bonded need be increased, cause manufacturing cost surging.And there are a variety of tools high in recent years
Ornamental micro structured pattern occurs, such as magnifying glass film (Fresnel film), embossment film, and these micro-structurals can also be with swashing
Light pattern (laser pattern is also a kind of micro structured pattern) cooperates, and reassembles into more ornamental pattern, then coordinate coloured silk
Color printing then turns into most attracting decorative pattern.
To solve the problems, such as that foregoing cost is too high, a kind of novel high-decoration multilayer flexible packaging film of exploitation is needed badly.
The content of the invention
It is a primary object of the present invention to disclose a kind of high-decoration multilayer flexible packaging film, escapable cost.
