Specific implementation mode
This document describes packaging and its manufacturing methods, and are formed using cold seal contact adhesive in particular, describing
Packaged in flexible film is to form at least part of method of packaging.Embodiment of the present invention allows with non-currently known in the art
Various ways formed packaged in flexible film.
For example, according to a kind of method, single laminate film layer can be used to form flexible stream by vertical method or horizontal process
Dynamic package packaging.The laminate may include the laying of film layer/hypothallus, contact adhesive (PSA) layer and covering psa layer.
In this case, the part of laying is peelable allows sealing to be configured to form packet adjacent to film layer to expose membrane part
Other parts inside dress are formed, and the package interior is configured as preservation of packaged content (for example, edible or other consumption
Product).Therefore, such as herein will be shown in an exemplary embodiment, the formation of vertical or horizontal packaging can be in peeling liner bed course
After carry out.
In some embodiments, added with padding can also be removed to form optional packaging feature knot from the film layer of lamination
Structure, such as fold, pouch, re-closed flap etc. and combination thereof.For example, re-closed feature structure may include：Film layer
Preset " kerve " (that is, extending only through the inside towards the laminate film layer of package interior) of the laying of casting die, to limit packet
Dress opening；And " inverted draw cut " (that is, extending only through the outside towards the laminate film layer of outer package), to delineate opening flap.
Another optional packaging feature structure can be by cutting added with padding layer to expose the PSA's adjacent with the product of package interior
A part provides to hold product within position appropriate.Another optional packaging feature structure can be attached by cutting
Blooming layer is to expose a part of the PSA of outer package, to allow adjacent packaging that (stacking) is kept to provide together.
In another illustrative methods, packaging can usually be formed by exposed coarctate two film layers of psa layer,
The PSA of the exposure is along or adjacent to (that is, within the 3cm of film edge, and be preferably ranges between 1mm between 1cm) film
The edge orientation of one or both of layer.In this case, at least one of described two film layers can be as described above
Laminated film at least film layer, psa layer and laying.In the method, a part for laying can be at predetermined bottom
It is removed after cutting, to expose the PSA of laminate film, to seal/be bonded to the second film layer.Optionally, packaging can be formed
It provides and pulls tongue, which extends beyond the part of exposed PSA, to allow user to pull open described two film layers,
To exposure package interior.This feature structure may additionally include in single film laminate method as described above.
It should be pointed out that although exemplary implementation scheme is described as using film laminate herein, can also make
With the film layer without liner.In some embodiments, PSA can be along the peripheral edge of a film layer in (or being adjacent to) film layer
Edge and other need PSA position carry out pattern application.In another embodiment, PSA is extrudable in packaging.At it
In his embodiment, laminate can have the psa layer being covered in entire film surface, but also due to excessive printing, UV light etc.
Etc. forming weakening area.
It should also be noted that as described herein, PSA sealings are " cold " sealings formed at ambient temperature, because
This need not form sealing by thermal activation.For example, environment temperature can be between about 20 DEG C and about 26 DEG C of (about 68 ℉ and about 79
Between ℉).Therefore, in packing forming process, heat is not applied to film, and the film is formed without thermal activation
Sealing.But this does not imply that thermal activation need to be excluded to form certain parts of the packaging of embodiment of the present invention.Thermal activation
Film can be used together with the PSA of application so that packaging optionally forms a part for packaging using thermal activation.Therefore, originally
Invention embodiment allows to form packaging without using heat seal, but one of packaging is also optionally formed using heat seal
Point.
Had the advantages that according to the packaging of invention as described herein embodiment formed through cold seal several.For example, cold seal
The use of part allows product of the packaging with low melting point, such as chocolate, ice cream, other candies etc..Saving heat-sealing step
In the case of rapid, speed of production can be improved.For the part that packaging is formed, eliminates heating film and formed needed for sealing
Time.In addition, as described above, psa layer press mold (that is, with packaging is formed simultaneously) or disengaging production line in the production line can be used
(that is, before forming packaging) forms the re-closed flaps of PSA.In addition, when forming package encapsulation portion using PSA, the thickness of film,
The composition of film and optional use of the laminate layers compared to heat-activated films are not critical.For example, since heat will not penetrate the thickness of film
Degree, therefore when forming cold seal packaging, film may be thicker.Therefore, remove and/or add the time as film thickness function, pressure
Power and heat variable.In addition, reducing the energy needed for the packaging of sealing embodiment of the present invention using cold seal PSA, because not
There are the energy needed for heating film.
Embodiment of the present invention allows a variety of manufactures to select, such as double films, double/multichannel, the formation of vertical and horizontal packaging,
Blister package, flow-wrapped, thermosetting packaging etc. and combination thereof.It may also comprise and be used in packing forming process
Accommodate the pallet of product.As described above, the bottom cross cutting on the laying of film laminate can be used for the shape of the packaging of cold seal formation
Cheng Zhong.In some embodiments, laying can be detached from production wire cutting.Liner can also be detached from production line removal.In some realities
It applies in scheme, due to the diameter narrows of deflector roll after removal laying and exposure PSA, separation layer can be used, so that wrapping
When film layer is unfolded during dress is formed, PSA is detached with the film layer.In other methods, due to film laminate after removal laying
Thickness will be thinning, therefore laying can be peelled off before packaged products.In the case of roller out-of-flatness, it may be difficult in vertical dress
Recessed cross cutting is carried out in bag application, but so that the part of laying is retained in position appropriate after a part for peeling liner bed course
Set has some superiority to expose PSA.For the non-surfaces PSA, by retaining in position laying, film laminate can
Such as forming tube is slipped in packaging is formed.Such case be it is possible because PSA can due to liner thickness and from forming tube
Surface it is recessed.Laying can be that (about 2 is close to about 200gauge by for example, about 40gauge (about 0.40 mil, about 0.0101mm)
Ear, about 0.0508mm).
Therefore, current embodiment allows to carry out cold seal packaging in vertical (and even horizontal) forming/filling is applied
It is formed.In one approach, laying and exposure PSA are removed before it will reach forming tube, it can be by PSA at the forming tube
It is applied to film, to form sealing at least part of packaging.Such sealing can be used in multiple combinations
Form one or more end sealings, fin seal portion, fold, pouch, opening flap etc..It is shelled when being added close to product
Farthest reduce from laying to the improved needs of equipment, caused by solving due to removing a part for laying
Film outward appearance offset issue (for example, out-of-flatness).In the case of deflector roll smooth (that is, not removing liner), the pot-life of film is more
It is long.For example, the metal liner layers of metal barriers can be removed, therefore it is not all to have barrier layer in all positions.As
Another option need not be isolated in the case where PSA is recessed after being detached from production line and removing laying on the top surface of deflector roll
Layer, therefore stronger adhesive can be used.
Fig. 1 shows that a kind of method for vertical packaging formation and sack-filling device, this method apply cold seal part to be formed
At least part of packaging.As described above, some permissions in embodiment of the present invention realized in same packaging heat seal and
The optional combination of cold seal part.For example, there can be vertical cold seal end close with four flour bag 30 of gained described below as shown in Figure 1
Envelope portion 70a and 70b and heat-sealing fin seal portion 72.Optional fold (for example, 126,128,130,132) as shown in the figure can be with
It is cold seal.In addition, embodiment of the present invention has been described as having fin seal portion 72.It should be pointed out that can be used all
Fin seal portion is replaced such as the other types longitudinal seal in lap seal portion.
Fig. 1 vertical form filled package apparatus 100, the 105 of Fig. 2 and the 107 of Fig. 3 in, when PSA 36 exposes, lead to
Often the prescribed film 74 of expected vertical bag (for example, packaging 30) will be difficult to pass through roller.However, as shown in Figure 1 to Figure 3, laying
38 are removed when close to forming tube 109.In this case, due to only one of the laying 38 before it will form packaging 30
Part is stripped, and separation layer is not needed on the top surface of film layer 37.PSA 36 is not contacted with the top surface of film layer 37.In these realities
It applies in scheme, since a part for laying 38 remains unchanged, PSA 36 is recessed and need not be connect with the thickness of laying 37
Touch roller surface.The laying 38 of stripping is the improvement of this field, because the PSA sealings applied protrude from film layer 37.However,
In the case where a part for laying 38 remains unchanged, PSA 36 is physically located below the top surface of film layer 37, so that tool
There is the film of exposed PSA to slip over the shaped portion and roller of packing device 100.Therefore, vertical bag application is possible.
Before reaching forming tube 109 remove laying 38 a part other the advantage is that when PSA 36 is not long
Between when being exposed to surrounding air, its pot-life is longer.In addition, on preformed roller, since film tool is there are two types of thickness, because
This may disequilibrium in the back roller for removing liner part.Therefore, it in this method it is preferred that, is use up in forming process
Possible evening ground peeling liner bed course 37, for example, being removed before it will reach forming tube 109.Whether shelled according to laying 37
From packaging building mortion 100 may include that optional insertion angle device 140, the insertion angle device can utilize cold seal part or heat seal.Limb
The upstream (Fig. 1) or in forming tube 109 (Fig. 2 to Fig. 3) that device 140 can be positioned on forming tube 109.
Example：Horizontal or vertical fin seal portion or lap seal portion, end part seal package, horizontal pocket type and pillow-type pocket type
Packaging.In a typical flow-wrapped packaging configuration, flexible membrane (such as, polyethylene (PP), oriented polypropylene (OPP) (OPP), gold
