Abstract

The present invention provides a kind of environment protecting paper aluminum compound packing material preparation method, includes the following steps：（1）Adhesive layer is respectively coated in aluminium foil two sides；（2）Hot sealing layer is pasted in a face adhesive layer, another side pastes paper layer；（3）In each one layer of glue of coating in two surfaces of the paper layer, the coating thickness of glue is 1 3mm, hot pressing；（4）The preparation method of glue is：Polyvinyl alcohol is made to the aqueous solution of 5 7wt%, is stirred evenly, the chitosan of 5 7wt% is added, stirs evenly, ultrasonic disperse 35 minutes to get；（5）Papery layer surface again compound one layer of printing layer to get environment protecting paper aluminum compound packing material.The two sides of paper layer is coated with chitosan by the present invention with polyvinyl alcohol binder, the toughness, water resistance and tearing property of milk of paper layer are not only increased, and there is antibacterial, anti-corrosion, humidity resistance, sealing performance is also improved, cause the flat appearance of material, the shelf-life of content can be greatly prolonged.

Description

A kind of environment protecting paper aluminum compound packing material preparation method
Technical field
The present invention relates to paper aluminium packaging material field more particularly to a kind of environment protecting paper aluminum compound packing material preparation methods.
Background technology
At present, the paper for being exclusively used in Tetrapack company of Sweden paper plastic-aluminum aseptic filler or other similar devices is plastic-aluminum combined sterile Packaging material mainly includes with lower structure from outside to inside：Protective polyethylene layer, paper layer, the first adhesive layer, aluminium foil, the second bonding Layer and polyethylene heat seal layer.Wherein, it in paper layer before lamination protective polyethylene layer, needs first in paper layer towards polyethylene The side printing packaging pattern of protective layer, therefore the printing effect of packaging pattern and the selection of paper layer are closely related.
Since the magma of papermaking is per se with the color of timber or stalk, and the paper concave-convex surface without coating process It is uneven.So the paper produced by the paper pulp without full bleaching, at all can not be directly as paper layer without coating process Carry out the printing of exquisite packaging pattern.Therefore, it is used paper layer is produced by the paper pulp of full bleaching paper, coated again Art post paperboard made of reason is formed.But paper pulp is after full bleaching, the toughness of fiber significantly reduces, the paper produced through impression, into It is easily broken after box；Also, by art post paperboard surface coating layer made of coating process impression, into box when be easily broken, cause Rupture printed patterns or packaging material；Moreover full bleaching and coating process not only cause serious pollution, are unfavorable for environment guarantor Shield, and drawn high the cost of paper layer.
Due to packing imprecision, paper layer is apt to deteriorate after making moist, grows bacterium so that the shelf-life of content is not It is long, and material softer, appearance are not smooth enough.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of environment protecting paper aluminum compound packing material preparation methods.
The present invention is achieved by the following technical solutions：
A kind of environment protecting paper aluminum compound packing material preparation method, includes the following steps：
（1）Adhesive layer is respectively coated in aluminium foil two sides；
（2）Hot sealing layer is pasted in a face adhesive layer, another side pastes paper layer；
（3）In each one layer of glue of coating in two surfaces of the paper layer, the coating thickness of glue is 1-3mm, hot pressing；
（4）The preparation method of glue is：Polyvinyl alcohol is made to the aqueous solution of 5-7wt%, is stirred evenly, adds 5-7wt%'s Chitosan stirs evenly, ultrasonic disperse 3-5 minutes to get；
（5）Papery layer surface again compound one layer of printing layer to get environment protecting paper aluminum compound packing material.
The paper layer is brown paper or kraft inner paper.
The printing layer is polyolefin.
Step（3）Hot pressing temperature for 85-95 DEG C, the time is 4-6 minutes.
The weight of the paper layer is 300-400/m2。
The adhesive layer is using polyethylene as the adhesion resin of base material.
Beneficial effects of the present invention are：The two sides of paper layer is coated with chitosan by the present invention with polyvinyl alcohol binder, no The toughness, water resistance and resistance to tear of paper layer are improved only, and there is antibacterial, anti-corrosion, humidity resistance, sealing performance also obtains It improves, and causes the flat appearance of material, improve the safety of food storing, the shelf-life of content can be greatly prolonged.
Specific embodiment
Embodiment
A kind of environment protecting paper aluminum compound packing material preparation method, includes the following steps：

（3）In each one layer of glue of coating in two surfaces of the paper layer, the coating thickness of glue is 3mm, hot pressing；
（4）The preparation method of glue is：Polyvinyl alcohol is made to the aqueous solution of 6wt%, is stirred evenly, the shell for adding 6wt% gathers Sugar stirs evenly, ultrasonic disperse 4 minutes to get；
（5）Papery layer surface again compound one layer of printing layer to get environment protecting paper aluminum compound packing material.
The paper layer is brown paper or kraft inner paper.
The printing layer is polyolefin.
Step（3）Hot pressing temperature for 90 DEG C, the time is 5 minutes.
The weight of the paper layer is 350/m2。
The adhesive layer is using polyethylene as the adhesion resin of base material.
