Abstract
Description
- This application claims priority to U.S. Provisional Patent Application No. 60/611,114, entitled “MULTI-LAYER FILM FOR FORMING A VACUUM PACKAGING BAG AND METHOD OF MANUFACTURE”, by Hongyu Wu, filed on Sep. 17, 2004, and which is hereby incorporated by reference in its entirety.
- The present invention relates generally to vacuum packaging film, and more particularly to patterned vacuum packaging film.
- Vacuum packaging film is used for vacuum sealing of perishable items. Due to the film's versatility in producing vacuum sealed packages of various sizes, its popularity has increased in recent years. As a result, continuous product improvement is required on the part of manufacturers in order to stay competitive. One such improvement has been applying patterns to vacuum packaging bags.
- For vacuum packaging bags with smooth inner surfaces (i.e., inner surfaces that do not have a pattern), the bag surfaces sometimes stick together when air is evacuated from the bag during vacuum packaging. This may result in air pockets within the seal and degraded seal integrity. In response to this problem, manufacturers may imprint or emboss a pattern onto vacuum packaging film used to form the vacuum packaging bags. The pattern helps prevent vacuum packaging bag surfaces from sticking together during vacuum packaging by forming channels along the grooves of an imprinted pattern—or forming channels between raised portions of an embossed pattern—when the surfaces of the bag are face to face. The pattern may be applied to one or both of the inner surfaces of the vacuum packaging bag.
- While imprinting or embossing a pattern onto vacuum packaging film is generally desirable, imprinting or embossing a pattern introduces new problems. For example, embossed patterns may be less durable than smooth surfaces. In general, the farther an embossed pattern sticks out from the surface of vacuum packaging film, the less durable the film becomes. Moreover, thicker embossing—or deeper grooves—typically consumes more material and may be harder to apply to or form into the film. Thicker embossing—or deeper grooves—also typically results in thicker vacuum packaging film, which makes the film heavier and less compact so it takes up more space in storage. Furthermore, if the surface of a vacuum packaging film has a high concentration of raised areas, there will be fewer channels formed when evacuating a vacuum packaging bag made of the film. Since there are fewer channels, even if relatively few channels become blocked gas may be trapped and air pockets formed, resulting in degraded seal integrity.
- Accordingly, what is needed is a vacuum packaging film with an improved embossing pattern to reduce embossing thickness, to reduce the concentration of raised areas on vacuum packaging film, or to increase the number of channels formed when the vacuum packaging film is used in a vacuum packaging application.
- The present invention fills these needs by providing a vacuum packaging film with an improved embossed pattern suitable for evacuation of gas from a vacuum packaging bag made of the film. In an aspect of the present invention, the embossed pattern includes a plurality of roughly parallel sequences of substantially collinear ridges. The ridges of a first sequence are offset with respect to the ridges of an adjacent second sequence.
- A method for making vacuum packaging film, in accordance with an aspect of the present invention, includes heat extruding a first material onto a spinning cooling roll and heat extruding a second material onto the spinning cooling roll. The first and second extruded materials bond and form a film of the first material with a plurality of roughly parallel sequences of substantially collinear ridges of the second material forming a pattern on the film. The pattern is operable to form channels suitable for evacuation of gas from a vacuum packaging bag made from the film.
- A vacuum packaging bag made of the vacuum packaging film according to an aspect of the present invention includes a first sheet and a second sheet. The first and second sheets are formed of the vacuum packaging film. The second sheet has a footprint substantially similar to the first sheet. The first and second sheets are arranged with respective second layers facing one another. The first and second sheets are sealed on opposing lateral sides and an end side, whereby the first and second sheets form a vacuum packaging bag with an opening for insertion of food or other product. The vacuum packaging bag is sealable at the opening.
- A vacuum packaging bag roll, suitable for forming vacuum packaging bags, made of the vacuum packaging film according to an aspect of the present invention includes a first sheet and a second sheet. The first and second sheets are formed of the vacuum packaging film. The second sheet has a footprint substantially similar to the first sheet. The first and second sheets are arranged with respective second layers facing one another. The first and second sheets are sealed on opposing lateral sides, wherein portions of the bag roll may be cut from the bag roll thereby creating a partially formed bag having opposing ends that are unsealed. Sealing one end of a partially formed bag forms a vacuum packaging bag with an opening at the other end.
- An advantage of the present invention is that the configuration of ridges of an embossed pattern allows gas to flow around blockages through alternative paths. Moreover, a patterned vacuum packaging film can be produced economically.
- These and other advantages of the present invention will become apparent to those skilled in the art after reading the following descriptions and studying the various figures of the drawings.

FIG. 2 depicts alternative vacuum packaging film patterns for the vacuum packaging film depicted inFIG. 1 . -
FIG. 3 depicts a conceptual view of layers of a multi-layer vacuum packaging film according to the present invention. -
FIGS. 4A, 4B , 4C, and 4D depict exemplary systems for manufacturing vacuum packaging film in accordance with the present invention. -
FIG. 5 depicts a flowchart illustrating an exemplary method for manufacturing vacuum packaging film in accordance with the present invention. -
FIG. 6 depicts a vacuum packaging bag roll made of vacuum packaging film according to the present invention. -
FIG. 7 depicts a vacuum packaging bag made of vacuum packaging film according to the present invention. -
FIG. 8 is a conceptual view of a cross-section of a vacuum packaging film according to the present invention. -
FIG. 9 depicts a conceptual view of a cross-section of a vacuum packaging film with a channel for evacuation according to the present invention. - The present invention provides a new embossed pattern for a surface of a vacuum packaging film. The term embossed, as used herein, is intended to mean that a pattern is raised or in relief and is not intended to imply a particular technique—such as cold-pressing, extrusion, or imprinting—used to apply the pattern. The embossed pattern is operable to form channels suitable for evacuation of gas from a vacuum packaging bag made of the film. The pattern, due to its advantageous configuration, should reduce the relative concentration and height of embossed ridges on the surface of the film. In an embodiment, the embossed pattern includes a plurality of roughly parallel sequences of substantially collinear ridges, where ridges of a first sequence are offset with respect to ridges of an adjacent second sequence. The offset ridges are operable to form multiple channel paths through which gas flows during evacuation of the vacuum packaging bag. Due to the offset, if a channel becomes clogged or collapsed, gas will seek one of many other alternative paths. The vacuum packaging film and an exemplary method for manufacturing the film will now be described. It should be noted that certain extraneous details were left out of the subsequent description in an effort to not unnecessarily obscure the true spirit and scope of the present invention.

FIG. 1 depicts a conceptual view of avacuum packaging film 100. The vacuum packaging film includes a plurality ofridges 102 arranged as a plurality of sequences ofcollinear ridges 104. The sequences ofcollinear ridges 104 are parallel to one another. In addition, theridges 102 of adjacent sequences ofcollinear ridges 104 are offset with respect to one another. This offset facilitates rerouting of gas when theridges 102 form walls of an evacuation channel. Consider, for example, agas flow 110. If thegas flow 110 encounters a blockage, thegas flow 110 can seek alternative routes to the left or right of the blockage. In the example ofFIG. 1 , thegas flow 110 flows to the right for illustrative purposes only. -
FIG. 2 depicts alternative vacuum packaging film patterns for the vacuum packaging film 100 (FIG. 1 ).FIG. 2 depicts azigzag pattern 200A, analternative zigzag pattern 200B, and awavy pattern 200C. It should be noted thatridges 202 of asequence 204 may be only approximately collinear. For the purposes of this application, for any set of ridges, if each of the ridges intersect a given line, then the ridges are referred to as “substantially collinear” along the line. Accordingly, thesequence 204 may be described as a sequence of substantially collinear ridges. It should further be noted that some of the ridges of a first series of substantially collinear ridges are not necessarily parallel to the ridges of a second series of substantially collinear ridges. Nevertheless, for the purposes of this application, for any given series of sequences of substantially collinear ridges, if the lines along which the substantially collinear ridges align are parallel to one another, the sequences are referred to as “roughly parallel.” Accordingly, the sequences of substantially collinear ridges ofFIG. 2A may be described as roughly parallel. - The alternative
zigzag pattern 200B andwavy pattern 200C are analogous to thezigzag pattern 200A so they are not described in detail herein. Moreover, it should be noted that the patterns ofFIG. 2 are depicted for exemplary purposes only. A great many different roughly parallel sequences of ridges with an offset would fall within the scope of this aspect of the present invention. Similarly, an uneven pattern (not shown) of ridges could have the effect of providing alternate routes if a channel is blocked. -
FIG. 3 depicts a conceptual view of exemplary layers of avacuum packaging film 100 according to the present invention. Thevacuum packaging film 100 includes astructural layer 302, abonding layer 304, a gas-impermeable layer 306, abonding layer 308, and a hear-sealable resin layer 310. Thestructural layer 302 provides strength to the multi-layer film. Thebonding layer 304 bonds thestructural layer 302 to the gas-impermeable layer 306. The gas-impermeable layer may be made of polyester, polyamide (nylon) or some other material that serves as an oxygen barrier to protect the contents of a sealed bag made from thevacuum packaging film 100. Abonding layer 308 bonds the gas-impermeable layer 306 to the heat-sealable resin layer 310. The heat-sealable resin layer 310 may be made of a polyethylene resin or any other heat-sealable material that is food safe. In an embodiment, the heat-sealable material must be food safe because it forms the inner layer of a bag used to store food. In an alternative embodiment, the heat-sealable material need not be food safe. - It should be noted that the
vacuum packaging film 100 could be made with as few as two layers, a gas-impermeable layer and a heat-sealable resin layer, bonded together without a bonding layer between them. The bonding layers and structural layer are optional in this embodiment. Moreover, in an alternative, the heat-sealable resin layer could be replaced with any sealable material, such as glue. -
FIGS. 4A, 4B , 4C, and 4D depict exemplary systems for manufacturing vacuum packaging film in accordance with the present invention.FIG. 4A illustrates anapparatus 400A for manufacturing vacuum packaging film in accordance with an embodiment of the invention. Theapparatus 400A includes amulti-layer extruder 402 that extrudes aplastic melt 404 onto aroller 406, which may be a cooling roller. Theroller 406 is embedded with an inverse pattern that turns in the direction ofarrow 408. The inverse pattern is for imprinting a pattern onto theplastic melt 404. As the multi-layer extruder extrudes theplastic melt 404, theplastic melt 404 comes in contact with the turningroller 406. As the melt is cooled, a pattern is formed on the melt at the same time due to the presence of the inverse pattern. As a result, a multi-layervacuum packaging film 410 emerges. -
FIG. 4B illustrates anapparatus 400B for manufacturing vacuum packaging film in accordance with an embodiment of the invention. Theapparatus 400B is much like theapparatus 400A (FIG. 4A ), but includes acooling plank 422. Instead of themulti-layer extruder 402 extrudingplastic melt 404 directly onto theroller 406, themulti-layer extruder 402 extrudesplastic melt 404 onto thecooling plank 422. Thecooling plank 422 has an inverse pattern. As theplastic melt 404 flows along thecooling plank 422, theplastic melt 404 congeals and is simultaneously imprinted with a pattern, due to the presence of the inverse pattern. The congealed plastic flows onto theroller 406, and a multi-layered, patternedvacuum packaging film 410 emerges as it is pulled along by theroller 406, which may or may not also have an inverse pattern. -
FIG. 4C illustrates anapparatus 400C for manufacturing vacuum packaging film in accordance with an embodiment of the invention. Theapparatus 400C is much like theapparatus 400A (FIG. 4A ), but includes anair knife 432. As theplastic melt 404 flows onto theroller 406, the air-knife 432 selectively etches a pattern onto themelt 404 with concentrated blasts ofair 434. Additionally, blasts ofair 434 also cause themelt 304 to congeal into multi-layered, patternedvacuum packaging film 410 that is pulled along by theroller 406. -
FIG. 4D illustrates anapparatus 400D for manufacturing vacuum packaging film in accordance with an embodiment of the invention. Theapparatus 400D is much like theapparatus 400A (FIG. 4A ), but includes aninverse vacuum 442. As theplastic melt 404 flows onto theroller 406, the inverse-vacuum 442 selectively “pulls” a pattern onto the melt. Additionally, theinverse vacuum 442 also causes the melt to congeal into multi-layered, patternedvacuum packaging film 410 that is pulled along byroller 406. -
FIG. 5 depicts aflowchart 500 illustrating an exemplary method for manufacturing vacuum packaging film in accordance with the present invention. The flowchart starts atblock 502 with heat extruding a first material onto a roller. The flowchart ends atblock 504 with heat extruding a second material onto the roller such that the first and second extruded materials bond and form a film of the first material with multiple roughly parallel sequences of substantially collinear ridges of the second material forming a pattern that is operable to form channels suitable for evacuation of gas from a vacuum packaging bag made of the film. - It should be noted that the method of manufacture using a
multi-layer extruder 402 is for illustrative purposes only. While the manufacturing technique can produce a vacuum packaging film with the advantageous qualities described herein, some other technique for imprinting a pattern onto a vacuum packaging film will also suffice, as is well-known in the art of vacuum packaging film manufacturing. It should further be noted that, depending on the technique for imprinting the pattern, a multi-layer vacuum packaging film may have the pattern imprinted on one or more of the multiple layers, or the pattern may simply be embossed only on the heat-sealable resin layer. -
FIG. 6 depicts a vacuumpackaging bag roll 600 made ofvacuum packaging film 100 according to the present invention. The vacuumpackaging bag roll 600 includes afirst sheet 602 ofvacuum packaging film 100 bonded to asecond sheet 604 ofvacuum packaging film 100 on opposinglateral sides 606. Thesecond sheet 604 has a footprint that is substantially similar to the footprint of thefirst sheet 602 so that the sheets fit together. Thefirst sheet 602 andsecond sheet 604 are arranged with respective heat-sealable resin layers 310 (FIG. 3 ) facing one another. Accordingly, the heat-sealable resin layer 310 may be referred to as the inner layer of a bag roll. Similarly, the structural layer 302 (FIG. 3 ) may be referred to as the outer layer of a bag roll. Portions of the vacuumpackaging bag roll 600 can be cut from the bag roll thereby creating a partially formed bag having opposing ends that are unsealed. -
FIG. 7 depicts avacuum packaging bag 700 made ofvacuum packaging film 100 according to the present invention. Thevacuum packaging bag 700 includes afirst sheet 702 ofvacuum packaging film 100 bonded to asecond sheet 704 ofvacuum packaging film 100 on opposing lateral sides and anend side 706. The first and second sheets form thevacuum packaging bag 700 with an opening for insertion of food or other product. In an embodiment, the vacuum packaging bag is heat-sealable at the opening. -
FIG. 8 is aconceptual view 800 of a cross-section of avacuum packaging film 100 according to the present invention. In the example ofFIG. 8 , the embossed pattern, as exemplified by theridge 102, is imprinted on the gas-impermeable layer 306 and the heat-sealable resin layer 310. As discussed earlier, thevacuum packaging film 100 could be made with additional layers, such as the bonding layer 308 (FIG. 3 ), some or all of which could also be imprinted with the embossed pattern. -
FIG. 9 depicts aconceptual view 900 of a cross-section of avacuum packaging film 100 with achannel 910 for evacuation according to the present invention. Asheet 902 is placed against thepackaging film 100 such that the embossed ridges of thevacuum packaging film 100 form walls of thechannel 910. Thesheet 902 may or may not have the same embossed pattern as thevacuum packaging film 100, but an embossed pattern is omitted fromFIG. 9 for illustrative purposes only. The heat-sealable resin layer 310 is the inner layer and the gas-impermeable layer 306 is the outer layer, also for illustrative purposes only. - While this invention has been described in terms of certain embodiments, it will be appreciated by those skilled in the art that modifications, permutations and equivalents thereof are within the inventive scope of the present invention. It is therefore intended that the following appended claims include such modifications, permutations and equivalents as fall within the true spirit and scope of the present invention. Moreover, the embodiments described herein are for exemplary purposes only and should not be construed to capture every embodiment of the invention. The invention is limited only by the claims.
