Definitions
- the presently disclosed technology relates generally to packages for containing product, such as, but not limited to, foodstuff or perishable items, and/or methods for forming packaging to utilize, and/or increase the effectiveness of, an active member, for example, to preserve product therein and/or prevent contamination thereof.

For example, some products require the absence of moisture or environments with a specific narrow window for relative humidity within a package. Other products degrade in the presence of ethylene. Still, other products, e.g., produce, such as lettuce, may risk being exposed to contamination and would benefit from a way to address the contamination, e.g., through release of an antimicrobial compound in the headspace of a package.

- the HFFS 180 can optionally include a pair of opposing upper or closing sealing bars or jaws 104b and a separator or cutting mechanism 105b. Following the cutting mechanism 105b, individual packages 130 can be placed or dropped onto an output or conveyor belt, for example.
- the second pair of opposing vertical sealing bars 182 is located downstream of the first pair of opposing vertical sealing bars 103b and upstream of the pair of opposing closing sealing bars 104b.
- the presently disclosed technology is not limited to such a configuration, as the location of the second pair of opposing vertical sealing bars 182 can be modified depending upon the type, size, and/or configuration of the package desired to be produced.
- the second pair of vertical sealing bars 182 can be located upstream of the first pair of opposing vertical sealing bars 103b.
- the second pair of opposing vertical sealing bars 182 can create or form one or more heat seals, ultrasonic seals, and/or inductions seals, as described above with respect to other sealing bars or jaws.
- the product 112 and the active member(s) 114 can be inserted into the partially formed package 130 simultaneously or in series.
- both the product 112 and the active member(s) 114 can be dispensed or dropped into the partially formed first and second compartments 116, 118, respectively.
- both the product 112 and the active member(s) 114 are inserted into the partially formed first and second compartments 116, 118, respectively, after or downstream of the second pair of opposing vertical sealing bars 182 and upstream of the pair of opposing upper or closing sealing bars or jaws 104b
- Figs. 10 and 11 show other examples of a HFFS 190, 196 according to optional embodiments of the presently disclosed technology, which are designed to form a package with the second compartment vertically adjacent and below the first compartment.
- the HFFS 190, 196 shown in Figs. 10 and 11 are substantially similar to that shown in Fig. 9 described above.
- Like elements between the three embodiments are identified with like reference numbers, and discussion of certain similarities between the embodiments may be omitted herein for brevity and convenience only.
- a difference between the embodiments is that the omission of the second pair of opposing vertical sealing bars 182 from the embodiment shown in Fig. 9 in favor of a pair of opposing horizontal sealing bars or jaws 192, 198 in the embodiment shown in Figs. 10 and 11.
- the pair of opposing horizontal sealing bars or jaws 192, 198 can be the third pair of opposing horizontal sealing bars or jaws.
- the pair of opposing horizontal sealing bars or jaws 192, 198 shown in Figs. 10 and 11 can be located upstream (see Fig. 10) or downstream (see Fig. 11), respectively, of the vertical sealing bars 103b. As shown in Fig.
- such a configuration can create a first compartment 116 above and separated from a second compartment 118 by one or more unsealed portions 120.
- the pair of opposing horizontal sealing bars or jaws 192, 198 can create or form the one or more unsealed portions 120.
- the at least one active member 114 can optionally be affixed to an interior surface of the film 101 used to make the package 130.
- the pair of opposing horizontal sealing bars or jaws 192 can optionally be vertically above the pair of opposing bottom seam sealing bars or jaws 102b.
- a method of forming a package using a form fill and seal machine wherein the package includes at least one active member therein to preserve or extend the freshness of product within the package.
- an active member can be placed in a compartment that is adjacent to a compartment holding perishable product, wherein the two compartments are sealed from the external environment but accessible to each other, thereby extending the shelf-life or preserving the product.
- a method of preserving perishable foodstuff in a package includes forming two compartments in the package through which gas can flow therebetween, wherein one of the compartments contains the perishable foodstuff and the other of the two compartments contains an active member.
- a package formed entirely and/or exclusively from film comprising: a first compartment and a second compartment, each compartment being sealed except for one or more unsealed portions between the first and second compartments, the first compartment being configured to hold one or more perishable product, the second compartment being configured to hold at least one active member, wherein gas is able to pass through the one or more unsealed portions to preserve or extend a useful like of the one or more perishable product.
- a method of forming a package with a form fill and seal machine comprising: sealing portions of a film to form a first compartment adjacent to a second compartment; inserting at least one perishable product into the first compartment; inserting at least one active member into the second compartment; and sealing a top of each of the first and second compartments to enclose the at least one perishable product and the at least one active member, respectively, therein, wherein one or more openings exist within the package between the first and second compartments to enable gas transmission between the compartments such that the at least one active member is configured to extend the shelf life or viability of the at least one perishable product.
