The present application relates to the technical field of food gravity box, in particular, the present application relates to a food gravity box with sealed flow channel for freshness preservation and display, which comprises a container device integrally formed by injection molding, wherein the container includes a display room and a storage room, with semi-elliptical sections, separated by a partition plate; wherein the storage room is composed of a partition plate, a front panel, a rear panel, a first side panel with a fillet and a first bottom panel which is obliquely arranged, and the first discharging port is formed in the bottom of the storage room; a sealing device used for sealing the feeding port in the upper portion of the container barrel; and a discharging control device connected to the first discharging port, between which a first sealing ring is arranged.

The present invention discloses a UV sterilization fresh-keeping box, including an accommodating box and a UV sterilization device removably disposed on a top side of the accommodating box. The accommodating box includes a box body with a storage space, and a lid disposed on the box body. The lid has a light transmission part to allow UV light to pass through, and a first assembling part disposed on a peripheral side of the light transmission part. The UV sterilization device includes a case, a UV module disposed in the case, a control module electrically connected to the UV module, and a second assembling part disposed on a bottom side of the case. The UV sterilization device is mounted onto the lid by combining the second assembling part with the first assembling part. The UV module is controlled by the control module to emit UV light towards the light transmission part, so as to sterilize the storage space.

Polymer or polymer inks are used for reducing or eliminating harmful chemicals by offering a neutralizing chemical in the path of movement of the harmful chemicals. A neutralizing chemical responsive to the harmful chemical produces a harmless chemical as an output that is in the path of the harmful chemical and is opposite phase with the neutralizing chemical, preferably by 180 degrees, or is at least opposite in chemical compatibility to some extent. The neutralizing chemical can be suspended or combined with an inert carrier and preferably attenuates the harmful chemical concentration. The polymer ink can be applied to a media such as paper, (embossed or extruded) or polymer the same as paper but also in foam (open cell preferred) in order to obtain a decrease in the concentration of harmful gases. These forms can be utilized in air or liquid applications.

A package comprises: a sterile barrier packaging film; self-sterilizing components comprising: a plurality of chlorite ions and water, wherein the self-sterilizing components are substantially free of an energy-activated catalyst and of an acid-releasing compound; a package interior formed by hermetically sealing the sterile barrier packaging film; and a headspace within the package interior comprising carbon dioxide present in an amount of greater than or equal to 5% by volume of the headspace. When the package is exposed to ultraviolet (UV) light having a wavelength of 254 nm, the chlorite ions react with the water to generate chlorine dioxide (ClO.sub.2), which is released into the headspace. In the absence of any UV light, there is not chlorine dioxide (ClO.sub.2) generation.

Regarding the oxyalkylene group-containing PVA-based resin, a package which is almost free from a problem associated with viscosity increase during melt-kneading even if the package is stored for a long time period, and a method for manufacturing the package are disclosed. The package comprises a bag having an oxygen permeability of 1000 cc/m.sup.2.Math.day.Math.atm or less as an amount of oxygen permeated in 24 hours per 1 m.sup.2 of its constituent film under an condition of 25° C. and 65% RH, and an oxyalkylene group-containing PVA-based resin in the bag. The package can suppress the oxidation of the oxyalkylene group-containing PVA and the generation of the carboxyl group-containing compound which may cause to increase viscosity during melt kneading.
