Abstract
The present invention discloses a paper-aluminum-plastic composite aseptic packaging material, which comprises an aluminum foil, wherein a first adhesion layer is coated on one surface of the aluminum foil in a film coating manner, a second adhesion layer and a polyethylene heat sealing layer are sequentially coated on the other surface of the aluminum foil in a film coating manner, a paper layer is adhered on the first adhesion layer surface away from the aluminum foil and is the paper incapable of directly providing the whiteness index and the smoothness index required by printing, and the paper layer surface away from the first adhesion layer is provided with a colored polyolefin layer. According to the present invention, the paper incapable of directly providing the whiteness index and the smoothness index required by printing is selected as the paper layer and the paper layer surface away from the first adhesion layer is provided with the colored polyolefin layer, such that the paper-aluminum-plastic composite aseptic packaging material with characteristics of breaking resistance, good printing effect and environmental protection is provided, and further has characteristics of clever idea, easy production, low production cost, and the like.
Description
Technical field
The invention belongs to field of packaging material, specifically, particularly to a kind of plastic-aluminum combined aseptic packaging material of paper.
Background technology
At present, it is exclusively used in Tetrapack company of Sweden paper plastic-aluminum aseptic filler or the plastic-aluminum combined aseptic packaging material of paper of other similar devices mainly includes following structure: protective polyethylene layer, paper layer, the first adhesive layer, aluminium foil, the second adhesive layer and polyethylene heat seal layer from outside to inside.Wherein, before film protective polyethylene layer in paper layer, need first paper layer towards protective polyethylene layer side printing packaging pattern, the therefore printing effect of packaging pattern and the selection of paper layer be closely related.
Due to papermaking oleo stock per se with timber or straw color, and the paper surface irregularity without coating process.So, by the paper produced without the paper pulp of full bleaching, the printing that exquisite packaging pattern can not be carried out without coating process directly as paper layer at all.Therefore, used paper layer is constituted by the paper produced of paper pulp of full bleaching, coated process is made again art post paperboard.But, paper pulp after full bleaching, the toughness of fiber significantly reduces, the paper produced through impression, become and be easily broken after box；And, through art post paperboard surface coating layer that coating process is made impression, become box when be easily broken, cause printed patterns or packaging material rupture；Moreover, full bleaching and coating process not only cause serious pollution, are unfavorable for environmental conservation, and have drawn high the cost of paper layer.
Content of the invention
The technical problem to be solved be to provide a kind of be not easily broken, printing effect is good, low cost, the plastic-aluminum combined aseptic packaging material of more environmentally-friendly paper.
Technical scheme is as follows: a kind of plastic-aluminum combined aseptic packaging material of paper, including aluminium foil, there is the first adhesive layer in the one side film of described aluminium foil, in the another side of aluminium foil, film has the second adhesive layer and polyethylene heat seal layer successively, it is bonded with paper layer in described first adhesive layer away from the one side of aluminium foil, described paper layer, for can not directly provide the paper of whiteness needed for printing and smoothness index, is provided with coloured polyolefin layer in described paper layer away from the one side of the first adhesive layer.
Described paper layer is uncoated kraft paper or kraft inner paper, and the paper pulp of the kraft paper of this paper layer or kraft inner paper be true qualities, the mixing of one or more of half drift or non-full drift paper pulp.
It is added with recovery paper pulp in constituting the kraft paper of paper layer or the paper pulp of kraft inner paper.
Described coloured polyolefin layer is mixed color masterbatches film and is formed by one of polyethylene and polypropylene or two kinds.
It is printed with packaging pattern in described coloured polyolefin layer away from the one side of paper layer.
The outer film of described coloured polyolefin layer after printing has protective polyethylene layer.
The quantification of 40g/m of described paper layer2-250 g/m2.
The present invention can not directly provide whiteness needed for printing and the paper of smoothness index to be used as paper layer by selecting, and in paper layer, coloured polyolefin layer is set away from the one side of the first adhesive layer, this coloured polyolefin layer is mixed color masterbatches film and is formed by one of polyethylene and polypropylene or two kinds, thus provide background color needed for printing using coloured polyolefin layer, and coloured polyolefin layer is even better in smoothness and ductility.
Because coloured polyolefin layer effectively can be covered to paper layer background color, therefore paper layer can using do not float or non-full drift paper pulp make, the type paper pulp is because limited without bleaching or bleaching, decrease the damage for paper pulp fiber intensity and toughness for the bleaching process, so that the paper layer deflection made and toughness are higher, packaging material perform better than during follow-up impression, one-tenth box, can substantially prevent risk printed patterns and packaging material rupture；Paper pulp fiber is limited without bleaching or bleaching simultaneously, and bleach consumption reduces, thus greatly reducing the pollution to environment in paper layer production process, beneficial to sustainable development；
In actual production, bonded with paper layer by coloured polyolefin layer, its surface smoothness is controlled by film machine cooling cylinder surface roughness, can obtain the smoothness better than coating layer, printing effect is more preferable；Therefore can be using the paper layer being not required to coating process, thus reducing the harm to environment for the coating process, beneficial to environmental conservation；
Coloured polyolefin layer main material be high ductibility resin so that coloured polyolefin layer has very high ductility, can substantially prevent printed patterns and packaging material rupture risk, this point be paper layer coated process after incomparable.Thus not only can reduce the harm to environment for the coating process using uncoated paper layer, and can be utilized the high ductibility of coloured polyolefin layer to make up the loss of the surface strength making paper layer containing partially recycled paper pulp and toughness, therefore can be in a large number using recovery paper pulp, beneficial to industry sustainable development, reduce the pressure to environment for the industry development；
Coloured polyolefin layer can provide the smoothness and ductility better than paper layer coating layer, therefore on this coloured polyolefin layer, the pattern effect of printing is good, be not easily broken, and can also be directly used as packaging material outermost layer；Protective polyethylene layer can also be increased printed patterns are protected, and increased protective polyethylene layer easily facilitates the longitudinal sealing of packing box；
To sum up, the invention provides a kind of printing effect is good, the plastic-aluminum combined aseptic packaging material of paper that is not easily broken；And alternative papery layer material commercially can be found everywhere, the indexs such as the required whiteness of printing, smoothness can not directly be provided after not coated or coating, and do not bleach or non-full bleaching kraft paper etc., the production cost of these paper is lower, production process is more environmentally-friendly；Paper layer directly can select these paper, is conducive to environmental conservation and cost control further.
Beneficial effect: the present invention can not directly provide whiteness needed for printing and the paper of smoothness index to be used as paper layer by selecting, and in paper layer, coloured polyolefin layer is set away from the one side of the first adhesive layer, thus provide a kind of be not easily broken, the plastic-aluminum combined aseptic packaging material of paper that printing effect is good, more environmentally-friendly, have and be skillfully constructed, produce easily and the features such as low production cost.
