  • Publication number: 20230106296
    Abstract: A method is described herein for slowing, inhibiting, and/or preventing the growth of microbes, or for killing microbes, within and/or on a product/good that is stored in a package. The method can include applying a film cover over a perforated portion of a package and securing the film cover to the package at the perimeter of the perforated portion with an adhesive or by heat stacking. The film cover can include a material for changing the atmosphere within the package. The package may be an existing pre-perforated package, or may be a package that requires perforation. If the package requires perforation, the method can further include perforating at least a portion of the package prior to positioning the film cover over the perforated portion. The film cover can be formed of a three-phase material or other material.

  • Publication number: 20230014429
    Abstract: Apparatuses and methods are provided for storing and preserving product, such as to extend shelf life of the same. In one optional method, liquid-exuding product is placed in a product containing space of a container atop a platform of a support structure. The container can include an internal compartment having the product containing space. The structure can define the platform for supporting the product. The internal compartment can further include a reservoir, configured to retain liquid, below the platform. At least one of the platform or the support structure can be configured to direct liquid exuded from the product to the reservoir. Optionally, the reservoir comprises or contains an absorbent material for absorbing liquid in the reservoir.

  • Publication number: 20210171269
    Abstract: A method of heating or cooking liquid-exuding product includes placing the liquid-exuding product onto a package (10). The package includes a porous material (20), an absorbent material (21) and a tray (12). The porous material is attached to or contacts at least a portion of the tray. The absorbent material (21) is located between the porous material and the tray. The method includes heating or cooking the combined liquid-exuding product and package. At least some liquid exuded from the liquid-exuding product during heating or cooking travels through the porous material (20) and contacts at least some of the absorbent material (21).

  • Publication number: 20170190498
    Abstract: A tray for supporting food products that exude liquid. The tray (12) includes a bottom panel (20) and side walls defining a liquid collection space (34). A plurality of upwardly extending protrusions (42) are positioned in a pattern across and along the bottom panel. A liquid absorbent pad (18) is positioned in the liquid collection space and has seams (47) that match the pattern of the upwardly extending protrusions, so the protrusions of the tray support the seams of the absorbent pad over the bottom wall of the collection space.
