Description
Technical field
The present invention relates to wrapping paper field.
Background technology
Plastic foil is widely used in flexible package, because they have for perishable farm products or with limited guarantor
Moisture barrier performance necessary to the appropriate preservation of the product of matter phase.
Paper is by fiber, is typically the material that cellulose fibre is made, therefore is the material with plant origin.They are
Natural porous and gas-permeable, therefore itself can not be used for the application.
It is well known, however, that paper and other materials (plastics, aluminium etc.) are combined to obtain packaging various products, especially easy saprophage
Barrier necessary to thing.In this case, paper substrates experience conversion operation, the conversion operation is included for example by discrete form
The coating for the coating that polymer is made, the extrusion coated of molten polymer or the lamination with plastic foil or aluminium film.The tool
The cost for having the paper-based composite material of barrier properties becomes expensive.
The A of document US 2 653 870 describe a kind of method for manufacturing wrapping paper.
The packaging being made up of the barrier paper manufacturing online is described in application WO 2011/056130.Online manufacture understands
Into the manufacture on the single tool of production is referred to, the single tool of production includes whole elements needed for production paper.
However, measuring condition that the barrier level proposed is limited to not to be strict (temperate zone, i.e., 25 DEG C, 75% phase
To humidity).The barrier level is measured by water vapor permeation rate, and weak barrier indicates high water vapor permeation rate.In the literature
Known " torrid zone " condition (i.e. 38 DEG C, 90% relative humidity) is more harsher than cryogenic conditions, therefore measured under the conditions of temperate zone
Barrier much weaker.
Statement " barrier paper ", which should be understood to refer to, includes the atresia paper covered with a layer or multiple layers of fibrous substrate, should
Atresia paper is sufficiently sealed to water vapour, to stop the water vapour can negatively affect the product included within a package
The amount of the integrality of preservation or product is penetrated into packaging.
The purpose of the present invention is especially but not solely moisture barrier paper, and it has marks according to ASTM F1249
The accurate at most 150g/m measured under the hot conditions of so-called 38 DEG C and 90% relative humidity2/ 24h, preferably less than 100g/
m2/ 24h water vapor permeation rate.
Advantageously, barrier paper is also heat-sealable, to allow by forming and packing the paper and its own sealing.
The manufacture of heat-sealable paper, which is related to, is for example placed on the coating of heat sealable polymer on cellulose base bottom.This
Kind of coating has extremely strong adherence when not dry, thus paper is allowed for before being wound with it is completely dry
It is dry, sticked to each other between each circle to avoid reel.
The application of the coating is generally carried out offline during one or more step of converting, and this makes it possible to have well
Coating quality, benefit from environment temperature when enabling to coating that coating will not be penetrated into exceedingly in fiber carrier

An extra step, which increases significantly cost and limit paper support packaged by plastic film flexible package in hair
Exhibition.Accordingly, there exist the economic needs of the productivity of the manufacture for improving moisture barrier type and heat seal type paper.
The content of the invention
The present invention relates to the development for the paper that moisture barrier performance and heat sealing performance are endowed during online manufacture.Should
Barrier type and heat seal type paper can be used for by the way that the paper and its own sealing are manufactured into packaging.
With it is online or it is offline apply heat sealing layer mode it is unrelated, in face of the problem of be promote be applied in fibrous substrate
Heat sealing layer, the deposition of more generally any coating (thermosealed or be not thermosealed).
It is generally contemplated that coating is less penetrated into fibrous substrate deeply, to be to be based on polymer when the coating
When and reduce the amount being applied on paper.In addition, the less infiltration of coating makes it possible to be more easily formed barrier film.
The use of Yankee drying cylinder (Yankee cylinder) is for reducing the first scheme of surface porosity.

Another option is to be ready for the presence of precoated shet to reduce the porosity of paper.
Another option is to be combined one of above option or another one.
In the preparation of precoated shet, using some hydrophobic and height film forming latex.
However, the hydrophobic property of precoated shet then can cause wettable problem during coating is applied, work as coating
When being aqueous, this causes the uncovered layer of the fibrous substrate being pre-coated with completely homogeneously to cover, especially in the height with paper
Speed online process in the case of.In addition, the surface of precoated shet can be when in accordance with well-known wettable rule, it is necessary to
Surface from coating can be fully different, to reduce the risk of moistening defect.
