A system for automatically sealing a plastic bag/enclosure over containers of biological materials carried on a pallet, comprising: a sealing system for automatically sealing a pallet bag enclosing a plurality of containers of biological materials wherein said pallet bag encloses the containers and an atmosphere surrounding the containers, the pallet bag optionally comprising at least one ACM and optionally including a reinforced portion. The pallet bag generally surrounds a number of flats or boxes on pallets containing fruits or vegetables that are sealed with or without a membrane to create an optimally suited atmosphere to control ripening, extend shelf-life, minimize microbial growth, maintain color, and maintain freshness.

The present invention relates to a one-way multilayer degassing valve, with positive-pressure control, which comprises one or more layers of a base substrate, one or more layers of a stretchable film and one or more layers of a filtering material. The invention also relates to packages comprising these valves and to a method for producing the same.

A vent for a package includes a multilayer laminate film comprising a vent having a first breach, a second breach, and a laser-formed channel extending therebetween, and the length and cross-sectional area of the laser-formed channel are configured to exhaust CO.sub.2 at a rate greater than a counter-flow diffusion rate for oxygen or water vapor.

A web of cleaning products and a method of manufacturing the same is disclosed. The web includes first and second carrier sheets and a plurality of pouches containing a cleaning composition. Each of the pouches is disposed in a respective depression formed in an upper surface of the first carrier sheet. A first internal atmosphere is enclosed within each of the pouches. The first carrier sheet is sealed to the second carrier sheet such that a second internal atmosphere exists between the second carrier sheet and the plurality of pouches. The second internal atmosphere has a greater absolute pressure than the first internal atmosphere so that the plurality of pouches and at least a portion of the cleaning composition in the plurality of pouches are compressed into the plurality of depressions in the first carrier sheet by the second internal atmosphere.

Pallet bag gathering apparatus to gather pallet bags for use in an automated pallet bag packaging system, preferably for the packaging of fruits or vegetables. The pallet bag gathering apparatus may be automated, semi-automated or manual in nature.

The present invention relates a method for increasing the shelf life of fruit comprising the steps of: treating a fruit with UV light from a UV light source, packaging the fruit in packaging film that allows the fruit to be stored in a modified atmosphere within said film, and storing the packaged fruit.

The invention relates to a packaging method, a transport package, and use of the packaging method for transporting products by means of a drone. According to the invention, a product to be packaged is placed in an open inner wrapping that is pretensioned on elastic traction cables in order to hold the product approximately centrally in an outer package. After insertion, the wrapping is closed and evacuated until it lies tightly against the product, and the traction cables are thereby further tensioned.

A web (8) of cleaning products (10) and a method of manufacturing the same is disclosed. The web includes first (20) and second carrier (30) sheets and a plurality of pouches (50) containing a cleaning composition. Each of the pouches is disposed in a respective depression (26) formed in an upper surface (28) of the first carrier sheet. A first internal atmosphere (80) is enclosed within each of the pouches. The first carrier sheet is sealed to the second carrier sheet such that a second internal atmosphere (82) exists between the second carrier sheet and the plurality of pouches. The second internal atmosphere has a greater absolute pressure (P) than the first internal atmosphere so that the plurality of pouches and at least a portion of the cleaning composition in the plurality of pouches are compressed into the plurality of depressions in the first carrier sheet by the second internal atmosphere.

The valve comprises a fluid inlet and/or outlet duct (8) comprising a flowrate regulator element (9) and a seating (10) for said fluid inlet and/or outlet duct (8), said seating (10) including a surface (10b) adapted to be attached to a portion of an internal bag (4) made of flexible material in the container (1), and is characterised in that it comprises a cover (11) to protect said seating (10) and comprising a hole for access to said fluid inlet and/or outlet duct (8); said cover (11) comprising means (13, 14) for securing a protective wrapping (5) enveloping the internal bag (4) on said seating (10). The container is characterised in that it includes at least one valve (3a, 3b) for the injection and/or extraction of fluid, and in that a portion of said internal bag (4) made of flexible material is attached to the seating (10) of the inlet duct (8) of said valve (3a, 3b) and that a portion of the protective wrapping (5) for said internal bag (4) is held against said seating (10) by the cover (11).

A packaging device allowing for the distribution, storage and cooking of various food products, such as perishable or frozen food product(s). The packaging device includes a plurality of micro-perforations that may promote the extended shelf-life of the perishable food product and the maintenance of the quality of the perishable food product or be configured to maintain the integrity of a frozen food product. The packaging device also includes a venting system that allows the cooking of the perishable or frozen food products within the packaging device.
