Abstract
The invention discloses a packaging bag film structure and a production method thereof. The packaging bag film structure comprises a printing film (1), a printing layer (2) and a PE (polyethylene) film (5), wherein the printing layer (2) is printed at the inner side of the printing film (1), the printing layer (2) is coated with a coating (3), and an aluminum layer (4) is plated outside the coating (3) and is composited with the PE film (5). Biaxially-oriented polypropylene (BOPP)-PE double-layer film is directly plated through the printing film, one printing coating procedure is only required, and aluminum is directly plated and is composed with PE to obtain the packaging bag film structure. The material cost is reduced and one compositing procedure is omitted.
Description
Technical field
The present invention relates to a kind of package construction and production method thereof.
Background technology
The membrane structure of current food pack is three layers, to be composited by surperficial print film, the aluminizer of centre and the PE film of nexine, this structural disadvantages is: its production process need to first print, and then PET film is aluminized, by twice compound (PET, PE), form, production cost is too high, also relatively wastes material.
Summary of the invention
The technical problem to be solved in the present invention: for the problems referred to above, provide food pack membrane structure of a kind of bilayer and preparation method thereof.
Technical solution of the present invention:
A packaging bag membrane structure, comprises print film, printed layers and PE film, and print film inner side is printed with printed layers, and printed layers is coated with coating outward, and coating is coated with aluminium lamination outward, and aluminium lamination and PE film are compound.
The preparation method of above-mentioned packaging bag membrane structure,
Look order printing-ink is pressed in step 1 printing coating in print film, then in the printed layers forming, intercepts coating, forms coating;
Step 2 is aluminized, the formation aluminium lamination of aluminizing in coating;
Step 3 is compound, and aluminium lamination and the gluing of PE film is compound.
In step 1, coating is high-barrier aqueous coating.
In step 2, aluminum layer thickness is 0.9-1.2 Ω/, the uniformity ± 15%.
Beneficial effect of the present invention:
The double-layer structure film of the BOPP+PE that print film is directly aluminized, can meet instructions for use, has saved again one deck BOPP film, and manufacture craft is also simpler, only needs an operation of the printing coating compound PE film that gets off directly to aluminize again.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
the specific embodiment:
The present embodiment is a kind of salt packaging bag, and its production process is as follows:
Print film 1 is universal BOPP film, and specification is 18um * 796mm, and PE film 5 specifications are 50um * 802mm.Being set as follows of plate roller and rubber roll:
Step 1 printing and coating: according to look order, ink printing is formed to printed layers 2 on print film 1, require clear patterns, chromatography is accurate, and form and aspect are correct, and color and luster is full.Then in printed layers 2, intercept coating, form the coating 3 of high-barrier water-based.Printing ink solvent proportioning n-propyl wherein: butyl ester=8:2(summer), n-propyl: ethyl ester=4:6(winter).Recheck afterwards and labeling.
Step 2 is aluminized: in coating 3, aluminize, form aluminium lamination 4, aluminium lamination 4 thickness are 0.9-1.2 Ω/, the uniformity ± 15%.
Step 3 is compound: the aluminium lamination of print film 14 and PE film is compound, adopt 200 object anilox roll, spread 1.5-1.8g/m
2, composite demand is non-wrinkle, layering, bubble, brilliant point, impurity, peculiar smell; Peel strength is good, even thickness.
Finally cut packing.
Claims (4)
