Abstract
The invention relates to a kind of interlined printing and packaging PVDC film for sausage casing and its production method. The packaging film includes an outer layer and inner layer which are combined together. The outer layer is a transparent PVDC film. The inner layer is a white PVDC film. The inner surface of the outer layer is equipped with a printing ink coating for internal printing. The production method is: perform internal printing over the transparent PVDC film through steaming, using the printing ink which can resist a temperature as high as 121 DEG C. Then use a combining machine to combine the printed surface of the transparent PVDC film and the white PVDC film. The printing ink is held between the two PVDC films. There is no need to apply bonding agent between the two PVDC films. The combination is realized under the jointed effect of the pressing force of the combining roller, the temperature and the contracting force of PVDC film. The interlined printing and packaging PVDC film for sausage casing has a better overall arrangement, brightness and colors.
Description
Technical field
The present invention relates to the PVDC packaging film, relate in particular to a kind of PVDC packaging film of packing ham intestines food, also relate to a kind of method for preparing this packaging film simultaneously.
Background technology
The PVDC film wets with resistance oxygen, the resistance of excellence and the digestion resistant stable performance makes it become the optimal material of packaged food.Conventional with the PVDC film be bilayer totally 40 ± 2 μ m are thick, it is red, yellow, orange etc. that the casing color is generally.The conventional table seal printing technology that adopts, table print face lacks stereovision, vividness and brightness.Its printed picture quality can not be given full play to PVDC blister-pack quality.Must have following condition and will produce strong, the dazzlingly beautiful PVDC packaging film of picture stereovision: (1) ink color is saturated, and the printer's ink layer is level and smooth, and the transition of shallow site evenly and do not have and lose phenomenon.(2) the printer's ink layer does not adsorb dust, impurity, and thermophilic digestion China ink layer does not come off antifade.(3) dissolvent residual is few, favourable food hygiene.
PVDC printing use all is two components of table seal and one-component PVDC printing-ink at home at present.The shallow dot loss of picture is serious during the printing of two component PVDC ink flow differences, be difficult to embody the picture stereovision, and printing ink can not reuse, and printing a period of time printing ink just need more be changed, and waste of material is big, the printing cost height.Though one-component PVDC table printing ink can print shallow site picture, Yin Qimo layer covering is low, the color and luster dimness, and it is not bright-coloured with regard to dimness to print out picture yet.
Summary of the invention
The object of the present invention is to provide a kind of PVDC casing sandwiched printing packaging film and production method thereof with lining India side formula printed picture, this packaging film picture stereovision, brightness, vividness are good.
For achieving the above object, the technical solution used in the present invention is: a kind of PVDC casing sandwiched printing packaging film, comprise the skin and the internal layer that are combined with each other, and skin is transparent PVDC film, internal layer is white PVDC film, and outer inner face is attached with the inner-printing ink layer by the printing of lining India side formula.
Described inner-printing ink layer is the anti-121 ℃ of thermophilic digestion solvent-borne type inner-printing inks of Polyurethane.
Self convergent force of pressure, temperature and the PVDC film of outer and internal layer dependence composite roll is directly compound, does not use adhesives in the recombination process.
The thickness of the thickness of outer transparent PVDC film and internal layer white PVDC film is 10～30 μ m, and the thickness of ink lay is 2～4 μ m.
The method of producing above-mentioned packaging film is India side formula printing in the anti-121 ℃ of thermophilic digestion printing ink of seal in transparent PVDC film is used, re-using compounding machine makes the printing surface and the white PVDC film of the transparent PVDC film after the printing compound, printing-ink is clipped in the middle of the two-layer PVDC film, intermembranous not being coated with of two-layer PVDC used adhesives, relies on self convergent force of pressure, temperature and PVDC film of composite roll directly compound.
Wherein, compound concrete grammar is the transparent PVDC film after the printing to be placed on first on the compounding machine to unreel, again white PVDC film being placed on second unreels, two PVDC films are respectively through unwinding device, and by flatten, Tension Control delivers in the composite press roller, composite roll pressure is 6～10kg/cm
2, the composite roll temperature is 50～70 ℃, two membranes need not any adhesives under the condition of this pressure and temperature and directly compound, cool off through chill roll then, again through flattening, rolling after the Tension Control, obtain interlayer casing packaging film.
In print steps, the print film width is 1120～1174mm, printing unwinding tension 8kg, feed tension 9kg, discharging tension force 10kg, 50 ℃ of baking temperatures, print out rate 100m/ branch.
In composite steps, composite print film unwinding tension 5kg, feed tension 6kg, coating tension force 8kg, coating drawing tension 8kg, compound PVDC film unwinding tension 8kg, compound back rolling tension force 12kg, rolling taper tension force 20%, baking temperature are room temperature, recombination velocity 100m/ branch.
Two-layer bonding abundant for guaranteeing, compound caudacoria volume need be deposited and cut at least 24 hours again.
The packaging film picture boiling solvent-borne type inner-printing ink of seal technology print is clipped in the middle of the two-layer casing in the PVDC casing, allows two-layer casing fully together bonding again, accomplishes that two-layer casing can not separate, and the casing packaging character is constant.
Packing film printing of the present invention uses quantity of ink few, packing picture exquisite appearance, bright-coloured, brilliant, and it is compound that dissolvent residual is few also without adhesives, and productive costs is low, efficient is high.Its performance perameter sees Table one and table two respectively:
