Description
Technical field
The invention belongs to composite package film and preparation method thereof, belong to the composite package film and preparation method thereof of windowing especially.
Background technology
The existing common packaging film of aluminizing is that all parts of face all have aluminizer to hide, and content can't well be showed.
Summary of the invention
The 1st technical problem to be solved by this invention provides a kind of die of content of can well showing and directly plates the composite package film of windowing.
The 2nd technical problem to be solved by this invention is the preparation method of above-mentioned composite membrane.
The technical scheme of technical solution problem of the present invention is: die directly plates the composite package film of windowing, and is respectively printing from outside to inside, the Biaxially oriented polypropylene layer of aluminizing, biaxial tension PETG layer, compound curtain coating polypropylene layer;
Described printing, the Biaxially oriented polypropylene layer of aluminizing are provided with the blank portion of demonstration package film content.
Preferred composite package film is 28 μ m printing, the Biaxially oriented polypropylene layer of aluminizing/12 μ m biaxial tension PETG layer/compound curtain coating polypropylene layers of 40 μ m;
Described compound curtain coating polypropylene layer is respectively corona layer, sandwich layer, hot sealing layer from outside to inside.
In order to improve the polyacrylic deflection of compound curtain coating, described sandwich layer is that HOPP and the blend of nucleation intensity strengthening agent are extruded, and the weight ratio of HOPP and nucleation intensity strengthening agent is 100:1-10.
In order to improve the polyacrylic transparency of compound curtain coating, also can in sandwich layer, add trimesic acid, the weight ratio of HOPP and trimesic acid is 100:1-10.
Preparation method of the present invention may further comprise the steps:
A) preparation section of bidirectional stretching polypropylene film prints, aluminizes:
B) preparation section of compound cast polypropylene film;
C) compound working procedure
D) divide cutting process;
The preparation section of the described bidirectional stretching polypropylene film that a) prints, aluminizes comprises following operation:
In bidirectional stretching polypropylene film printed design pattern operation, show that at needs the blank parts of content applies water-soluble gloss oil, remainder applies high temperature resistant gloss oil operation, the operation of aluminizing, washes the aluminium operation.
Described high temperature resistant gloss oil is the high temperature resistant gloss oil of X-A18 type of Shantou maple China company.
Described water-soluble gloss oil is the water-soluble gloss oil of DM-515 type of Shantou maple China company.
Because in printing process, a part of high temperature resistant gloss oil is coated in above the printing zone printing ink, and need to aluminize on the gloss oil surface.Therefore some requires below needing to satisfy:
1) reactionless with the look China ink, the China ink of checking colors does not dissolve.
2) temperature of aluminizing in the process is very high, so this gloss oil will have high-temperature resistant result preferably, can effectively protect printing-ink in evaporate process, not corroded by aluminum vapor.
3) strong with the printing ink bonding force, with aluminium coated adhesive force is preferably arranged also, guarantee washing aluminium process good surface appearance effect.To above-mentioned requirements, selected the high temperature resistant gloss oil of X-A18 type of Shantou maple China.
Water-soluble gloss oil is the blank space that is coated in no printing zone, in washing the aluminium process, with it together with being attached to top aluminium lamination flush away.Therefore some requires below needing to satisfy:
1) combine with film itself fully, densification can not have and lose a little, or problem such as particle line.
2) good water solubility is met water and can completely fast be peeled away with film.
3) gloss oil good leveling property, easy and uniform applies.
To above-mentioned requirements, selected the water-soluble gloss oil of DM-515 type of Shantou maple China.
The present invention compared with prior art has the transparency height, and printed patterns is clear accurately, the characteristics that deflection is good.

In Fig. 1,2,1 is that printing, the Biaxially oriented polypropylene layer of aluminizing, 2 are that biaxial tension PETG layer, 3 is compound curtain coating polypropylene layer; 4 is that corona layer, 5 is that sandwich layer, 6 is hot sealing layer.
The specific embodiment
Below in conjunction with embodiment the present invention is done detailed explanation.
Bidirectional stretching polypropylene film of the present invention (28BOPP)
The key technical indexes:
Biaxial tension pet film (PET film)
The key technical indexes: table (2)
Embodiment 1:
Die directly plates the preparation method of the composite package film of windowing, may further comprise the steps,
A) preparation section of bidirectional stretching polypropylene film prints, aluminizes:
In bidirectional stretching polypropylene film printed design pattern operation, show that at needs the blank parts of content applies water-soluble gloss oil, remainder applies high temperature resistant gloss oil operation, the operation of aluminizing, washes the aluminium operation.
Described washing in the aluminium operation, described live-roller is a drive roll, washing aluminium liquid is water.
Described high temperature resistant gloss oil is the high temperature resistant gloss oil of X-A18 type of Shantou maple China company.
Described water-soluble gloss oil is the water-soluble gloss oil of DM-515 type of Shantou maple China company.
B) preparation section of compound cast polypropylene film;
Corona layer: homopolymerization PP (FC801MX)
Sandwich layer: 95% homopolymerization PP (FC801)+nucleation intensity strengthening agent 5% (FIS600)
Hot sealing layer: ternary polymerization PP (FL7632L)+opening agent (AB10S)+slipping agent (SL07PP)
FC801MX: degree of crystallinity is high, and deflection is good, and processability is good, and antiblock is prone to surface corona and handles.Be used for three-layer co-extruded corona layer in this resin.Ash is few, and impurity is few, and film-formation result is good.
FC801: degree of crystallinity is high, and deflection is good, and processability is good, contains the slipping agent of certain amount, and this resin is used for three-layer co-extruded sandwich layer.
FL7632L: ternary polymerization pp, fusing point is low, antiblock, smooth property is good, and the hydrostomia processability is good.Be used for the 3rd layer, play good low-temperature heat-sealing effect.
AB10S: the opening agent, the effective ingredient particle diameter is even, and opening property is good.
