Prior art Such a package is known from US 5,126,518. In this known package some parts are provided with a layer of microwave-reflective n-iaterial and other parts not to effect a decreased flow of mic:rowave energy to the foodstuffs in certain zones of the tray and an enhanced flow of microwave energy to the foodstuf:fs in the remainder of the tray.
Summary of the invention An objective of the invention is to provide a package comprising a tray with various compartments in which different types of food are present, with one type of food being present in each compartment, which compartments are closed off by a film structure that is sealed to the tray around the openings of the compartments, above each compartment of the tray a part of the film structure being present, and at least a number of these parts of the film structure are different from each other, in which individual circumstances can be created for the various types of food and for preservation of the food in the different compartments. To this end the package according to the invention is characterized by the fact that these parts are gas-permeable and/or that a material which reacts with gases in the respective compartments is provided in and/or on the film structure. This creates circumstances for the food in the package that are adapted per type of food. For example the space in a compartment of the package can be fully sealed off from the outside environment by an gas-impermeable part of the film structure, or indeed interacting with the outside environment by way of a gas-permeable part of the film structure. For example in at least some of the parts of the film structure there can be perforations.
Therefore, in one aspect of the invention, there is provided a package comprising a tray with various compartments in which different types of food are present, with one type of food being present in each compartment, which compartments are closed off by a film structure that is sealed to the tray around the openings of the compartments, above each compartment of the tray a part of the film structure being present, and at least a number of 2a these parts of the film structure are different from each other, wherein these parts of film structure are gas-permeable or wherein a material which reacts with gases in the respective compartments is provided in or on some of these parts of the film structure.
In another aspect of the present invention, there is provided a working method for separately packaging various types of food in a single package, comprising:
placing food on a tray with different compartments open on one side, with one type of food being placed in each compartment, then placing a film structure above the open sides of the compartments, whereby above each compartment a part of the film structure is placed, at least the characteristics of some of the specified parts of the film structure are different from each other, followed by sealing the film structure to the tray around the openings of the compartments, wherein the film structure is processed such that some of the parts of the film structure are gas-permeable or are provided with a material in or on the film structure which material reacts with gases in the respective compartments.
In addition, the various characteristics can be acquired because the film structure is comprised of various films, for example a first film and a second film or a sticker that is present on parts of the first film, or two or more films beside each other with different characteristics.
It is noted that from US-A-4,935,252 a food package is known having a film structure comprising two films of which one is applied on the other and can be removed. This package contains only one compartment.
Furthermore the differentiation of the film structure only 2b relates to characteristics for preparation of the food and not for preservation.

In addition, the various characteristics can be acquired because the film structure is comprised of various films, for example a first film and a second film or a sticker that is present on parts of the first film, or two or more films beside each other with different characteristics.
It is noted that from US-A-4,935,252 a food package is known having a film structure comprising two films of which one is applied on the other and can be removed. This package contains only one compartment.
Furthermore the differentiation of the film structure only 2b relates to characteristics for preparation of the food and not for preservation.
It is noted that from European patent no. 0 293 794 B1 a worl=tii.ng method is kriown in which various types of food are packaged in a sizzgle package. To improve the shelf life of the rar.ious types of food, in the known working method. the varLol.zs types of food are stored under different atmospheric conditions. Some types of food are preferably stored in a;ri. oxygen-low environment while others instead are better stored in an atmosphere that is rich in oxygen.
By utilizing a differentiated film structure according to the prese:nt invention in which the closure of each compartment can be coordinated with the type of food present in the compart'ment and the condition of the food, an optimal environment can be created for the food. In this way even in a package where no separate gas atmospheres are present in the compartments good cir=cumstances can nonetheless be obtained for the food.
For example the material can be an active substance which is placed in andJor on the parts of the film structure. The substance might be a material that reacts with the oxygE~n in the compartment and thus removes the oxygen from the compartment and the food. This is desirable for those types of food that can be stored best in a low-oxygen atmosphere, for example f:or the protection of flavor and aroma aga=_nst oxidation. Such substances are generally known, for example films that contain iron powder. The iron powder rusts and oxygen is withdrawn from the food and the atmosphere iri the compartment. Instead of iron powder ascorbic acid or sulpri.ite can asso be used as an active substance. These substances, too, oxidize and oxygen is withdrawn frorn the food. and the atmosphere in the compartment. :In addition, enzymatic-acting substances can be applied to the film, such as glucose oxidase or ethanol oxidase in which enzymes are catalysts for an oxygen-consuming reaction.
The substance can also be a material, for example, that absorbs oxygen, fr:)x- example a film of nylon polymer in which cobalt is present for a cobalt-catalyzed oxidation of the nylon polymer. Instead of, or in addition to, oxygen-absorbing subEitances, the film or sticker can also contain CO2 absorbing or emitt:i.ng substances, or ethylene absorbing substances, ethanol emitting substances, moisture-absorbing substances, et.c. All of these substances are generally known.
The material can also be formed by applying a film structure that: is activated upon radiation. By only radiating a number of the parts of the film structure, a film structure with var=,r:ing characteristics is created. The material of the film structure should in this case be such that its characteristics can be changed by radiation or because certain substances in the materi.al of the film structure can be activated by radiation. For example as a result of radiation the material. can be activated such that for example i.t: obtains the characteristic that it reacts to oxygen and thus remove.s the oxygen.from the compartment.
Such a film i.s, known from European. patent application EP-A 0 520 257. This k:nown film contains a combination of an oxidizable organic com:pound and a metallic transference catalyst. Here oxidation of the organic compound can be initiated by radiation.. This known package consists of only one compartment. Furthe:rmore in this known package the entire film is irradiated, there is no differentiation of the film. The manner of radiatirig is known from the international patent a.pplication WO 99/21699. In this way food can be packaged both in a low-oxygen environment and a high-oxygen environment in a single package.
The invention also relates to a working method for separately packaging v<:irious types of food in a single package, comprising: placing food on a tray with different compartments cpen on one side, with one type of food being 5 placed in each compartment, then placing a film structure above the open sides of the compartments, whereby above each compartment a part of the film structure is placed, at least the characteristics of some of the specified parts of the film structure are different from each other, followed by sealing the film structure to the tray around the openings of the compartments.
As far as the working method is concerned the invention is characterized in that the film structure is processed such that some of the parts of the film structure are gas permeable and/or are provided with a material in and/or on the film structure which material reacts with gases in the respective compartments.
Processing the film structure can comprise for example placing perforations in at least a number of the parts of the film structure, for example to allow the food to breathe. The size of the perforations or the number of perforations can be adjusted depending on the degree of respiration of the food. A film with microperforations can also be used.
The composition of the film structure can for example take place by using first one film and then on parts of that film placing a.,second film or sticker. The second film or sticker can for example contain the above-mentioned active substance or consist of one of the above-mentioned materials that influerlce radiation. Or the first film can be perforated and the second film or sticker can be gas impermeable a:zd seal c:ff parts of the first film.
5a The film structure can also be composed for example by fastening two films to each other, after which one of the films is locally removed. The one film can for example be perforated and the other film can be a gas-impermeable film that is placed in separate parts on the perforated film. Parts of the gas-impermeable film can for example be peeled off the perforated film.
Yet another 11.nethod of composing the film structure can for example be to .E.Dlace two or more films with different characteristics beside each other on the tray. For example the various films can contain an active substance, be perforated, be made of a radiation-influencing material, or be gas imperm.eable. Possibly the films can first be connected with each other before being placed on the tray.
The composition and/or processing of the film structure preferably t.akes place before food is placed on the tray. ThiEe decreases the chance that waste materials that may occur du:ring the processing end up in the food.
Anot.her favorable embodiment of the working method according to t.he invent.ion is characterized in that, before the film structure is composed and/or processed, first the characteristics of the food are determined, after which the composition arid/or processing of the film structure takes place accordirig to the characteristics of the food. Thus the conditions under which the food is stored can be better coordinated with the actual condition of the food. For example, if the respirat:.ion of the food is high, it may be desirable that. the space in the compartment be more connected with the environment, such that a film structure with high permeability is desirable.

Detailed description of the drawings In Figures 1 and 2 an embodiment of the package according to the invention is shown in a top view respectively cross-section along line A-A. The package 1 is comprised of a tray 3 that has various compartments 5, 7, and 9 that are open on top. The compartments are closed off by a film structure 11 that is fastened via sealing seams 13 to flanges 15 of the tray 3.
In the compartments 5, 7, 9 there are various types of food 17, 19. For each type of food an optimal closure of the compartment is present, because the film structure I 1 is divided into various parts 21, 23, 25, that have different characteristics and each close off a compartment. For example part 21 and parts 23 and 25 form individual films 27 en 29 that are fastened side by side on the tray. Films 27 and 29 are for example transparent gas-impermeable films. To obtain optimal conditions in the compartments, for example, part 23 of the film 29 is provided with perforations 31 and another part 25 of the film 29 has a non-transparent sticker 33 that seals off the space in the compartment against light.
To further improve the conditions under which the various types of food are packaged, various preservative gases 35, 37 can be introduced into the compartments.
Figure 3 is a diagram showing a first embodiment of the working method according to the invention for packaging different types of food in a single package.

Figure 4 is a diagram showing a second embodiment of the working method according to the invention. Here the process of composing and/or processing the film structure is integrated into the process of filling the trays and the fastening of the film structure to the trays. After filling the compartments of the tray 53 with different types of food 55, 57 the condition of the food is measured. Depending on the conditions the machine 49 is set. In this manner for example the number of perforations per surface unit can be set.
Thus the package can be even better coordinated with regard to the type of food being packaged.
The film structure can be comprised in various ways. Figure 5 shows a first embodiment of the composition of the film structure and placement on a tray.
Here the two different films 61 and 63 form, side by side, the film structure 65, and each film seals off one or more compartments of the tray 67.
