Description
Technical field
The present invention relates to a kind of method that bends packaging laminate, this lamination is by the cellulose fibre manufacturing, and this packaging laminate comprises: main body promoting layer (a bulk promoting layer), be called as body layer herein, and it comprises the network architecture of cellulose fibre; And at least one side layers at least one side of body layer, this side layers and this body layer directly or indirectly combine on their opposed facing whole surfaces mutually.
Background technology
In the manufacturing of packing, the material that is made of packaging laminate is usually bent, thus, bending device is used for forming indenture at material.Described bending device can be configured with circle and the thin marking-off plate of smooth edges, or has circle and the indent wheel of smooth edges, and it is pressed onto material in the depression of meticulous moulding in the mould.By this depression, material is weakened at so-called folding line place.In bending, laminated material is folded to outside the lamination plane, thus, is in a side of lamination at broken line, and promptly indenture forms on the opposite side of side and forms projection.So broken line is as folding impression so that material is to the straight possibility that is folded into of required angle, normally 90 ° of this angles, but also but other angle, for example 180 ° also can occur.The different geometries of bending marking-off plate etc. and mould is used for the different materials quality (corresponding to different lamination quality and stack types) of individual material properties, to obtain determined bending impression as well as possible.Usually reformed is the thickness of marking-off plate or some other bending devices, the width of impression or the bending degree of depth in the mould, and promptly how dark bending device press.
The folding feature of tradition is, and is folding away from a side of making the material impression.So, form projection (bulge) in the inboard of the bent angle that folds connection location formation.In for example 180 ° burst, this means that folded stack will have a thickness, this thickness is greater than the twice of double-deck laminated thickness.In addition, at littler angle place, this bending and folding will cause a projection, this projection is extended at the inboard upper edge of bent angle broken line.
The reason that forms projection during folding traditional lamination is on the sidepiece of the extruded lamination of burst, compression fissure to have occurred.Via folding the action that is squeezed into projection by the projection (projection) that the bending marking-off plate forms, compression fissure increases.Its original plane shape because concentrating of the interior material of fold line, lamination are tended to rebound.This means that folded edge becomes circle easily, especially with to be subjected to load relevant, for example, when gripping with hand on the packing of parallelepiped-shaped or on several packings of piling up each other.
So, the transfer that problem relevant with the bending of the tradition of traditional lamination and shortcoming are material outside the plane and/or to the material transfer of folding line, this has produced bossing and fold over laminate thickness is increased, and associated other problem be fold line because of distortion will can be not straight in the extreme, except not attractive in appearance, the difform packing that also will produce abreast or stack with overlapping each other.On the possible baffle layer or thin layer that comprises for example aluminium film, plastic film, paint film etc., the distortion of fold line also can become the fracture impression.If for example film has been coated with on the side that is plated in lamination, and membrane material is more crisp than the cardboard of lamination, and then bossing or other the irregular part that occurs in burst may cause crackle in rete.May require the senior cardboard quality of high quality printing or top finishing can use dark colour, lacquer etc. to apply, print.Thereby the impression of bending marking-off plate may cause the damage of finish coat, and when carrying out away from bending marking-off plate indenture place, this damage may become the crackle that appears the bottom lamination coating when folding.
A kind of known method that reduces the problem of this bossing is described in patent SE 467 302, and wherein, the distortion of the bending marking-off plate of protrusion is eliminated by machine up.Yet this method has many shortcomings, for example intensity reduction, efflorescence etc.
Another kind is intended to reduce the known method of bossing anamorphic effect to be described in patent SE 432 918, wherein, has used auxiliary folding line so that material is migrated out from folding line self.
It also is well-known arranging some parallel folding lines, and thus, an angle is broken down into some a plurality of angles of pressing close to arrange each other.Yet the shortcoming of the method is, has obtained very large gross thickness.For example, 180 ° burst, it is obviously big than double-deck laminated thickness that gross thickness will become.
Described among patent SE 507 095 from another method that folding line is removed bossing, bonding being eliminated in the lamination between the different layers is so they are out of shape independently of one another.
In all above-mentioned examples of the solution of the problem of material transfer, be typically in the fold line that the distortion relevant with bending causes, measure is to remove or material for transfer from fold line, or another kind of scheme is to avoid the gathering of material in the fold line.
In the patent EP 565 013 that relates to another kind of problem, the material of being made up of several layers has been described, core is formed by the shredded paper of extruding.Show that also this material can be with being provided with a plurality of grooves, this makes it pliable and tough, and it can be used to wrap up difform object thus.Thereby in definite implication of literal, the document does not relate to by the packing that is folded to form, and does not show folding line or bending method.
In patent EP 484 726, how constraint agent extruding foaming or that expand in folding has been described, with the drawing stress in the minimizing aluminium foil layer.
In patent EP 546 956, the material of the central core of the cellulose fibre with expansion has been described, it is recited as the processibility with improvement.
From patent US 2,770,406, a kind of packaging laminate of cicada, this lamination comprises pory body layer, this layer is compressed when folding.According to the document, body layer especially has the polystyrene layer manufacturing of closed cell by the foamed plastic layer.This material fine really in 1956, but in view of environmental requirement, promptly present requirements such as recycle, it is needed material anything but.At patent US2, also narrated in 770,406, with a kind of paper board material of similar type shown here in, when moulding, crackle will crackle occur in the corner of cardboard on the outermost layer that craft paper is done.So according to this document, the problem that crackle forms has only solved in the lamination that is made of cellulose and plastics, but does not clearly have in the lamination that is mainly formed by cellulose fibre.In addition, the document is not in fact described bending method self at all and how to be carried out.
Patent FR 1,341,855 have described the lamination of being made by corrugated cardboard, it comprises cellulose fibre certainly, but it is different from according to lamination of the present invention, because body layer is not to use the network architecture of cellulose fibre to form, this lamination combines with the side layers of cellulose fibre on their opposed facing whole surfaces basically.In Fig. 2 a-b of patent FR 1,341,855, show the prior art relevant with this application, it is described to cause and damages the problem relevant with distortion.So, be described to cause the method for this problem according to the bending of Fig. 2 a-b.In Fig. 3 a-b, show a kind of traditional bending, it is described to be better than to a certain extent shown in Fig. 2 a-b that, but according to patent FR 1, the solution of 341,855 invention comprised shown in Fig. 4 a-c alternatively, i.e. outermost layer " bending " that be cut open or punch.
Summary of the invention
The objective of the invention is to provides a kind of bending method for the packaging laminate by the cellulose fibre manufacturing, this packaging laminate comprises a main body promoting layer, be called as body layer herein, and at least one side layers at least one side of body layer, this side layers and this body layer directly or indirectly combine on their opposed facing roughly whole surfaces, and this method purpose is to avoid the problems referred to above.
The invention still further relates to a kind of packaging laminate that has according to the folding line of this method, and a kind of packing of making by folding this lamination.This lamination is preferably with acting on packing liquid and solid food and also being used for the packaging industry goods and the material of other commodity, perhaps as a kind of freak oil that are used to produce this material or other final products.
