Description
Technical field
The invention belongs to food-grade field of packaging material, and in particular to a kind of painting for being used to prepare packaging material for food
Cloth latex.
Background technology
Polymeric packaging material is often requested to have choke, protection against the tide because content is different, guarantor is fragrant, prevent fat migration etc.
A variety of functions, the packaging material of single variety can not usually meet this requirement, and therefore, polymer composite is in packaging field
It is widely used, particularly in terms of film article, different use requirements can be met from different barrier packaging materials.
Large-scale barrier material is mostly leaching membrane paper on existing market.Current leaching membrane paper is exactly coated plastic pellet by casting machine
In the composite of paper surface, main feature is exactly that this composite with grease proofing, waterproof (relative) and be able to can be sealed.
But the high polymer material (plastics) used in leaching membrane paper is substantially polyethylene (PE), polypropylene (PP) class has following deficiency：Polyolefin
The plastics of class can hardly be degraded, and pollution, non-environmental protection barrier material are produced to environment；And needed when reclaiming by materials such as PE and PP
Material is first separated with paper, then recycling, big for the film separating difficulty of low grammes per square metre, adds great amount of cost and energy consumption, and
And existing leaching membrane paper is due to the barrier with very high grease-proof and waterproof, (especially high temperature food), water in direct packaged food
Steam can not pass through barrier layer, and portion forms aqueous water and absorbed by food within a package, causes the change of the color, smell and taste of food etc..
The content of the invention

Grade defoamer, its consumption is preferably 1% mass parts.
According to another preferred embodiment of the present invention, it is characterised in that：Described calcined kaolin is that 6250 mesh are forged
Kaolin is burnt, its consumption is preferably 28% mass parts.
According to another preferred embodiment of the present invention, it is characterised in that：Its consumption of described deionized water is preferably
25-35% mass parts.
The coating latex of the present invention is used to prepare the compound package material that novel environment friendly can be used for contact food.
Technical scheme obtains following technique effect：
(1) extrusion coating paper prepared by latex coating of the invention is Biodegradable material, can reduce the pollution to environment,
It is environmentally friendly material.
(2) extrusion coating paper prepared by latex coating of the present invention, can directly crush into papermaking when paper is reclaimed and be beaten system
System.
(3) extrusion coating paper prepared by latex coating of the invention, oil resistivity test uses T559 standards, takes KIT12 grades of surveys
Test solution is tested, and the grease proofing grades of KIT reach 12 grades.
(4) extrusion coating paper prepared by latex coating of the present invention, while with higher Water-proof and oil-proof performance also have compared with
High water vapo(u)r transmission.
