referring now to the drawings , decorations 10 made according to the method of the present invention are shown operatively located on the icing 12 of a foodstuff 14 in the form of a cake . in this regard , it will be noted that the decorations 10 appear to be integral with the icing 12 and are decoratively arranged in a manner determined by a user . in the exemplification depicted in fig1 the user selected decorations 10 in the form of hearts 10 a which the user placed alignably around the side of the cake , and further placed pre - printed lettering 10 b which is specific to an occasion ( in this case a twenty - first birthday ) to the top of the cake . in order to accomplish the aforesaid decorative effect on the foodstuff 14 , the user utilized a reinforced edible film 16 composed of an edible film 18 which is releasably attached to a flexible substrate 20 ( see fig5 ). the edible film has been cut and the edible film printed upon to provide the decorations 10 a , 10 b depicted in fig1 . the edible film 18 is itself sufficiently gossamer so as to unobtrusively meld into the icing 12 , while the substrate 20 provides sufficient structural integrity for the edible film so that it may be easily and effectively processed into a decoration , such as for example printing and cutting thereof . the edible film 18 is preferably a water soluble polymer film , such as that manufactured by dow chemical company of midland , mich . under the trademark methocel . methocel encompasses a range of both methylcellulose and hydroxypropyl methylcellulose in a wide range of viscosities , hydroxypropyl methylcellulose being preferred . however , other kinds of edible films known in the art may be used . the substrate 20 is a food product compatible , flexible sheet which has the properties of releasably adhering to the edible film 18 in a manner that admits of hand peeling and further of providing mechanical handling integrity for the edible film so that the edible film may be processed , such as by printing and cutting , into a decoration . an example of an acceptable substrate 20 is mylar , preferably 3 mil dupont eb - ii mylar sheet . other food product compatible substrates may be used . a preferred method of preparing the preferred edible film 18 is as follows . firstly , a solution 21 of edible film material must be provided . in the case of hydroxypropyl methylcellulose , the following steps are suggested by dow chemical company which makes use of the principle that hydroxypropyl methylcellulose is insoluble in hot water : disperse in water the hydroxypropyl methylcellulose product using ⅕ to ⅓ the required total amount of water as hot water ( 176 to 194 degrees f .) while agitating the water , upon thorough wetting of the hydroxypropyl methylcellulose particles , the remaining water is added as cold water while continuing agitation , after a smooth solution has been obtained at less than 77 degrees f . the agitation is continued for approximately 20 minutes . the ratio of hydroxypropyl methylcellulose to water is predetermined to arrive at a preselected viscosity of the resulting edible film . additional ingredients may now be stirred into the solution , one at a time , so that the final properties of the edible film formed therefrom are as desired . for example , the following additives may be added to the solution . a plasticizer , such as propylene glycol may be added to control elasticity of the edible film , to control adhesion of the edible film to the substrate , and to provide variation in surface sheen of the edible film . starch may be added to build edible film body , to control opacity thereof and to provide variation of surface sheen of the edible film ( it tends to create a matte finish ). a colorant in the form of an approved food color controls the color of the edible film . a flavoring in the form of an approved food flavor , such as for example oils , extracts and artificial flavors , controls the taste of the edible film . examples of solutions 21 for providing the preferred edible film 18 are as follows . next , the solution 21 is formed into a film geometry upon the substrate 20 . this is accomplished by either a manual forming apparatus 15 ( see fig2 through 4 ) or by an automated forming apparatus 28 ( see fig1 ). the manual forming apparatus 15 includes a glass base 22 which lays horizontally on a surface ( not shown ) such as a table . the substrate 20 is laid upon the glass base 22 and the edges thereof , including opposite edges 20 a , 20 b , are taped by a mylar tape 24 having a non - permanent adhesive to the glass base 22 . the thickness of the tape 24 defines the thickness of the edible film 18 to be formed . accordingly , the thickness of the edible film is controlled by varying the tape thickness itself or by adding or subtracting layers of the tape . a thickness range of between 0 . 0004 to 0 . 0015 inch is preferred for providing unobtrusively thin , gossamer edible films . thicker edible films can provide more flavor and provide greater mechanical strength for manipulation by a user . a glass wiper 26 is placed edgewise onto the tape 24 at each edge 20 a , 20 b of the substrate 20 so as to be slidable therealong . a preselected quantity of solution 21 is poured onto the substrate 20 and starting from one end of the substrate 20 , the wiper 26 is wiped along the tape 24 in the direction indicated by arrow m while being inclined acutely ( approximately at 45 degrees to the substrate ) in the direction of the wiping movement . the speed of movement is maintained so that the solution 21 is formed into a uniform film geometry as the wiper 26 slides on the tape 24 . the solution 21 now having a film geometry must be dried . drying may take 12 to 14 hours in room temperature ambient air , but the drying time may be shortened significantly by increasing air temperature and circulation . the tape 24 may be removed at any time . upon the completion of edible film drying , the result is a reinforced edible film 16 in the form of an edible film 18 releasably adhered to a substrate 20 , as shown in fig5 . the automated forming apparatus 28 , shown in fig1 , provides commercial quantities of the reinforced edible film 16 . the process line 28 a is logically controlled , as for example by a programmable logic controller , such as an allen - bradley scl 500 . programmability allows flexibility in adjusting sequencing , process line speed , etc ., via a personal computer and software interface . the substrate 20 is provided as a coil 20 a and is decoiled at a dccoiler station 30 . the decoiler station 30 preferably provides two coil positions , one in a process position on - line and one in a reload position off - line . the two positions alternate as the decoiler station 30 is allowed to shift transverse to the process line 28 a . this effects to reduce idle manufacturing time while reloading a new substrate coil , so that one is always in the process position . an example of a coil 20 a of substrate 20 in the form of dupont 3 mil eb - ii mylar film has a width of between 18 and 55 inches and a length of 6 , 200 feet . the decoiler station 30 is electrically driven preferably by a dc drive and is asynchronous to the process line drives . a tension arm 32 provides a buffer between the coil drives and the process drives . the tension arm 32 is structured to maintain constant tensioning of the decoiled portion of the substrate coming off the substrate coil 20 a . the substrate 20 is drawn up to the process line by cushioned , spring tensioned wheels 34 which are arranged in two opposing rows , one on either side of the substrate , so as to supply a pinching force to the substrate as it passes thereby . the wheels 34 contact about 1 inch of the substrate surface , upper and lower . the substrate 20 is supported between the rows of wheels 34 by a flat teflon coated plate surface 35 to prevent sagging of the substrate as it is transferred . a casting station 36 is provided , consisting for example of a 50 gallon tank 36 a holding the solution 21 overhead the substrate 20 . a plurality of nozzles 36 b , such as for example 10 nozzles uniformly spaced across the width of the substrate 20 , are solenoid operated to allow gravity feed of the solution 21 from the tank 36 a to the substrate 20 . the solenoids are logically controlled to meter the solution flow rate at the nozzles 36 b so as to conform with line speed as based upon the rate of rotation of the drive wheels 34 . a plurality of casting stations may be located sequentially along the process line 28 a so as to provide ready change in the solution formulation so as to minimize line disruption . trailing the casting station 36 is a forming station 38 . the forming station 38 provides for leveling , smoothing and thickness control of the edible film 18 being formed from the dispensed solution 21 . a wiper 38 a in the form , for example , of a single plate of tempered glass is located transverse to and overhead the substrate 20 . the overhead location is controlled by finely threaded screws with respect to a stationarily affixed mounting bracket 38 b , which overhead location relative to the substrate 20 determines the thickness of the edible film 18 . the edible film 18 is formed as the substrate 20 passes beneath the wiper 38 a and is thereupon leveled and smoothed . the wiper 38 a is inclined with respect to the substrate 20 at an acute incoming angle , preferably of around 45 degrees . next , a dehydration tunnel 40 provides filtered and heated air in forced circulation adjacent the drying , newly formed edible film 18 . the temperature and rate of air circulation is controlled to adjust to line speed and solution formulation . after the dehydration tunnel 40 , the now more - or - less dried edible film 18 is ambiently dried and cooled at a finishing station 42 , resulting in a finished reinforced edible film 16 . lastly , the reinforced edible film 16 is either rolled or cut to size at a final processing station 44 . the edible film 18 may thereafter be die cut to provide decoration defining score lines and / or the edible film may be imprinted at one or more adjacent in - line stations ; otherwise , the reinforced edible film 16 may be taken elsewhere for storage , shipping or further processing . turning now to fig6 through 13 , the method of use of the reinforced edible film 16 will now be detailed . fig6 and 7 show how the foodstuff 14 was decorated using the reinforced edible film 16 . fig6 shows a sheet of the reinforced edible film 16 , wherein the edible film 18 has been imprinted with the edible ink design of the top decoration 10 b and the side decorations 10 a . the edible film 18 has a die cut score 10 c which defines the top decoration 10 b . the user removes the edible film 18 carrying the top decoration 10 b from the substrate 20 by starting peeling at the score line 10 c by using his or her fingernail , which may be facilitated by gently folding the substrate at the score line 10 c , to peel the top decoration 10 b off from the substrate 20 , as shown in fig7 . the user then places the top decoration 10 b onto the top of the foodstuff 14 in a pleasing placement thereupon , as shown in fig1 . the side decorations 10 a are provided in strips having die cut score lines 10 c which define rows of decorations that facilitate side - by - side alignment of the decorations around the side of the foodstuff 14 . the edible film portions carrying the side decorations 10 b are manually peeled off from the substrate 20 with the initial aid of the user &# 39 ; s fingernail by either gently folding the substrate at the score line 10 c or starting peeling at the edge and then peeling off the edible film from the substrate in the same manner as shown in fig7 . the decoration 10 b is then placed upon the side of the foodstuff 14 as shown in fig1 . it will be understood that preferably the edible film 18 is gossamer , wherein its thickness is sufficiently thin so that it basically disappears as against the foodstuff 14 , which in this case is the icing 12 thereof . in this regard , moisture of the foodstuff 14 transfers to the edible film 18 , causing adherence of the edible film to the surface of the foodstuff without destroying the edible film in the process . accordingly , an incredibly professional foodstuff decoration has been effected independent of the discretionary income and artistic acumen of the user . fig8 through 12 show variations of methods of using the reinforced edible film 16 . fig8 depicts a reinforced edible film 16 having a pre - printed , pre - cut ( see score lines 10 c ) edible film 18 in the form of finalized decorations 10 d for use at a specific occasion . fig9 depicts two examples of sheets of reinforced edible film 16 . the upper example depicts a sheet of reinforced edible film 16 having a colored edible film 18 with pre - cut ( see score lines 10 c ) decorations 10 f for use at a generic occasion . the lower example depicts a sheet of reinforced edible film 16 having an edible film 18 that has pre - printed , pre - cut ( see score lines 10 c ) decorations 10 e . fig1 depicts a non - printed , uncut sheet of reinforced edible film 16 for any occasion , in which the edible film 18 is to be printed upon by a user and the reinforced edible film cut by the user so as to provide user finalized decorations 10 g , such as depicted in fig1 . with regard to fig1 , the user is utilizing a writing instrument 46 , preferably a pen of the felt tip variety , having contained therein colored edible ink to draw the decorations 10 g . the process depicted in fig1 shows the decorations being free - hand drawn by the user . the user could also have traced the decorations by placing the reinforced edible film 16 over some depiction , and then following the outlines or features of the depiction visibly through the reinforced edible film . it is also possible to supply the reinforced edible film 16 with the edible film 18 partly pre - printed , wherein the user finalizes the decoration by marking upon it . for example , the top decoration 10 b shown in fig1 and 6 may have only the generic words “ happy birthday ” and the user writes in the celebrant &# 39 ; s age , in this case the numeral “ 21 ”. it is also possible for sheets of reinforced edible film 16 as depicted in fig1 to be utilized by printing facilities to produce generic and / or personalized printing upon the edible film 18 . the printing may include special messages , pictures and / or drawings , other source materials or any combination thereof . because of the substrate 20 , the printing facility can handle the reinforced edible film 16 similarly to the way it would handle paper , thus making available practically any printing machine and printing method for creating decorations , provided , of course , edible inks are used . finally , fig1 depicts a kit 48 for use to decorate a foodstuff , such as for example a cake . the kit 48 contains a plurality of sheets of reinforced edible film 16 , which may include , for instance , colored , flavored , tasteless , opaque , or clear edible films and may further include pre - printed and / or pre - cut edible films for purposes consonant with an identified occasion . the kit 48 optionally includes a plurality of assorted colored edible ink writing instruments 46 , which are preferably of the felt tip pen variety for user utilization as generally depicted in fig1 . over - all , the following advantages of the reinforced edible film and the method of its use are : 1 . the edible film can be made very thin , on the order of 0 . 0004 inches , wherein it is so gossamer that it will essentially disappear when applied to a foodstuff , yet the substrate will give it mechanical workability while it is being fashioned into a decoration . 2 . the edible film may be mass produced and easily stored over long periods . 3 . the edible film may be clear , colored , opaque or anything in between . this facilitates pre - printing and user marking upon the edible film ( such as for example by printing , writing or drawing upon it ). it also facilitates pre - cut and user cut design shapes of the edible film being decorative in their own right . 4 . the edible film may be easily die cut to provide score lines that at least in part define the areal definition of decorations while the substrate is not cut . gentle folding of the substrate at the score line permits a user to easily use his or her fingernail to begin the peeling of the edible film from the substrate . alternatively , if available , the user may use his or her fingernail to begin peeling at the edge of the edible film . 5 . the reinforced edible film may be easily cut with scissors or a knife by a user , and the user may even use a razor blade or razor knife to cut through only the edible film and not cut through the substrate when defining the areal extent of the decorations being finalized . 6 . the edible film may be tasteless or flavored , thereby enhancing the taste of the foodstuff , or simply unaffecting its taste . 7 . the substrate facilitates handling of the edible film in a manner customary of paper , yet the edible film itself may be extremely delicate . the edible film may be placed into conventional printing presses , pen plotters , ink jet printers , silk screen printers , and so on , and may be hand marked upon , rubber stamped , etc . yet , easy manual release of the edible film from the substrate makes the edible film itself simply accessible when it is time to apply it to a foodstuff . 8 . the reinforced edible film may be supplied in sheets wherein the substrate delivers the mechanical rigidity that is appropriate for user defined shape cutting . 9 . the reinforced edible film may have pre - printed , partly printed or non - printed edible film , wherein the user may add or supply user defined marking thereupon . 10 . the reinforced edible film may be sufficiently translucent so as to enable a user to trace onto the edible film portion of the reinforced film a depiction constituting any picture , graphic , drawing , etc . that has been placed beneath the reinforced edible film . 11 . the reinforced edible film may be supplied in kit form for a user to customize the decoration of foodstuffs , wherein the kit may include a plurality of assorted reinforced edible film sheets and edible ink writing instruments . 12 . the reinforced edible film may be utilized by commercial businesses to transfer newly created or user supplied video , photographic , computer generated images , text , graphics or other source to the edible film and then present the decorated reinforced film to the user customer . this can even be performed on a mail order basis . 13 . the edible film carrying the decoration will absorb moisture from the surface of the foodstuff upon which it is placed and thereupon adhere to the foodstuff without the edible film being destroyed thereby . it is to be understood that the edible film may be used alone without the substrate for purposes of providing foodstuff decorations in the manner as outlined hereinabove , and that reinforced edible films are described herein only by way of preferred example . further , the term “ marking ” is to be understood to mean causing any kind of indicia to be placed upon the edible film , such as , for example , by printing , writing , drawing , or any other image transfer means , and may include causing selected additives in the edible film solution to produce patterns in the dried edible film . it is to be further understood that the edible film and method of use therefor may be used with any foodstuff , including , but not limited to confectioneries , inclusive of candies and ice creams . further , foodstuffs ordinarily not having surface moisture sufficient to adherably hold the edible film thereto may be supplied by the user with the requisite surface moisture . for example , spraying water upon the surface of a dry foodstuff can supply sufficient moisture so that the edible film 18 adheres to the surface of the foodstuff . to those skilled in the art to which this invention appertains , the above described preferred embodiment may be subject to change or modification . such change or modification can be carried out without departing from the scope of the invention , which is intended to be limited only by the scope of the appended claims .
an edible film and method of using same for decorating foodstuffs , in particular baked goods , wherein anyone can easily , inexpensively and artistically decorate foodstuffs . the edible film according to the present invention is composed of an edible polymer film which is preferably releasably mounted upon a flexible substrate to provide a reinforced edible film . the edible film is peelably released from the substrate to provide decorations for the foodstuff . the edible film may be decoratively prepared into predetermined decorations prior to distribution , which may include being pre - printed , pre - cut , colored , or being of pre - selected opacity and sheen . pre - printing may be accomplished by any suitable printing process utilizing edible inks . alternatively , the edible film may be distributed in a not yet finalized decoration form , wherein finalization is left up to the user . for example , the reinforced edible film may be distributed without being pre - printed or only partially pre - printed , wherein the user controls subsequent printing , writing , drawing or otherwise marking upon the edible film , such as by use of edible ink writing instruments . further , the user may purchase sheets of the reinforced edible film and thereafter cut the reinforced edible film sheets into shapes defined by the user .
