Description
Technical field
The present invention relates to a kind of packing that are used to make packing container,, the present invention also relates to the manufacture method of above-mentioned packing in particular for the compound package material in sterile filling field.
Background technology
In beverage filling equipment, the rolling packing trail and become band, and banded packing are shaped to ellipticity on working direction, and the ellipticity packing further are shaped to the cylindrical packages material, and dual-side is by longitudinal lap joint involution (vertical envelope), and forms a pipe.This pipe is at the horizontal involution of one end (horizontal sealing), and the top (or bottom) of formation packing container.Fill required content, with the corresponding laterally involution (horizontal sealing) of the residue end of pipe, and the bottom (or top) of making packing container.Cut the horizontal sealing zone by cutting knife then, to form single packing container, as selection, by corresponding folding and shaped device, packing container along folding line by folding and form final shape, the i.e. packing container of brick shape or other shapes further.
The rolling packing that are used for packing container at present, mostly be composite material, by the 3-5 layer material lamination integral body that is composited, not easily separated, wherein comprise at least: a firm supporting layer of strengthening packing container that reaches, keep liquid quality and the innermost layer that carries out the themoplasticity involution, between supporting layer and innermost layer innermost layer, isolation layer is arranged, starvation and sunlight and prevent that the product taste runs off, the conductive layer when also being high-frequency induction simultaneously.
Vertical dual-side of rolling packing, for cutting forms, directly overlap joint forms when indulging envelope, can expose to the content of finished product packing.At this moment, packing contain absorbing material, and as paper or cardboard, content can be inhaled in the packing, and is softening thereby packing are corroded, even danger such as leakage occurs.On the other hand, in aseptic packaging, if isolation layer contains metal, as aluminium foil, this does not have the cutting edge of protection not contact in inclusion, must be protected with some mode, because metal pair food has negative effect.
A kind of known method that prevents the inclusion direct contact of cutting edge and packing container is to use plastic tape longitudinally, as PP (polyethylene) bar, cutting edge is covered, and this plastic tape moves forward, crosses cutting edge and sealing on packing in-to-in plastics covering when forming pipe.The limit of packing and the limit on opposite are superimposed, so the landing edge of packaging material tube is firm and durable.But shortcoming is a packing container at the vertical thickness of wire area will be the twice of packing container remainder, make that the regional transition of vertical envelope is level and smooth inadequately, not only influence attractive in appearance but also be unfavorable for automatic boxing and carrying on the manufacturing line.
Chinese patent ZL97193921.7 (denomination of invention: banded laminated packaging material, its manufacture method and the packing container of making by these packing) adopt the method for the oblique cutting in edge of material band, the edge is wrapped up by an independent stage of laying, and the edge after the cutting is covered the heat sealable material of one deck fully.
But in oblique cutting, cutting be with the horizontal plane direction at angle of material band on carry out, this angle must be enough little, so that it is good bonding that external covering layer is obtained along beveled edge, but this angle again must be enough big simultaneously, so as to make this edge in machinery and depository comparatively durable when carrying.Therefore, the very difficult control technology of cutting sth. askew guarantees that the angle of cutting sth. askew is suitable.
Summary of the invention
The purpose of this invention is to provide a kind of packing, when vertical envelope, do not have cutting edge to expose, and the thickness of lap-joint is less than the thickness of two times packing own to the content of finished product packing.
The technical solution adopted in the present invention is: the vertical side area of packing is up and down symmetry, semi-closed structure, from outside to inside at least by innermost layer, isolation layer.
The method of producing above-mentioned packing is: cutting Zhao impression Zhao is coated with the compacting of sticky agent Zhao flanging Zhao.
Packing form to seven tunic composite structures by three layers.At least comprise: supporting layer, isolation layer, innermost layer in addition, can also have uppermost layer, viscous layer.
Uppermost layer refers to the close overplate of liquid of appearance plastics, and the actv. protection can be provided the content in the packing container, does not allow moisture and liquid invade in the packing, is made of thermoplastic material such as polyethylene.
Supporting layer, promptly sandwich layer refers to have higher mechanical strength, is used for keeping the shape with the supporting package container.Sandwich layer can be given the profile favorable mechanical stability of packing container, and this packing container can be distributed in simple mode, is handled upside down easily, can adopt the special-purpose cardboard of food as base-material.
Isolation layer is used for starvation and sunlight and prevent that the product taste runs off, the conductive layer during simultaneously as electronic heating.Can adopt and contain metallic paper, the metallic conduction material as aluminium foil and steel foil filler also comprises by formed conduction tunics of step such as vapor deposition, plating, printings.Because conductive layer has electric conductivity, when applying high-frequency currents on the coil externally, in conductive layer, will produce inducing current because of high-frequency induction, inducing current produces heat, and be delivered on the innermost layer through conductive layer, internal layer is heated, softens and fusing by this heat, thereby forms sealing area.
Innermost layer is the innermost layer of wall of container, in the food liquid direct contact, the quality that can keep content prevents liquid phase for the infiltration of container support layer and wetting, and the softening and fusing by heat in heat-sealing, to form sealing area, can adopt thermoplastic material, as polyethylene etc.
Viscous layer: for strengthening between uppermost layer and the supporting layer, and firm between isolation layer and the innermost layer, can add sticky agent in the centre.If sticky agent adopts thermoplastic materials such as polyethylene, make viscous layer similar with uppermost layer and innermost layer material, can this layer not listed separately.
One longitudinal edge of packing is cut away part, form outstanding jumper.Impression on jumper applies sticky agent, and the part that the impression of jumper is outer is on the folding also part of sealing-in in the impression of jumper of impression.
Packing of Xing Chenging thus, because of jumper have around plastic layer (innermost layer) protection, so make when indulging the package packaging container, do not have cutting edge to be exposed to content.
Also can carry out impression to above-mentioned sheet material aptly, promptly by dimpling tool, make sheet material have indentation line so that in follow-up technology, sheet material can easier be folded into a final packing container.
The packing container shape of being made by packing of the present invention can have brick shape (parallelepiped), and shape such as hexagonal prism shape, tetrahedroid, gable-top shape.
