This invention relates to a shrink wrap machine, which includes a central column and a shrink film synchronous transmission equipment. Said central column is provided with a first column and a second column which are configured to mutual suspended separation for removing the connection between the first column and the second column so that the shrink wrap machine can be expand to fit onto the desired diameter range of bottles or cans and increase the application of the shrink-film. When the shrink-film is opened by the first column of the center column, the shrink-film will be continuously transport by the label feeding rollers and the label pulling rollers of said shrink film synchronous transmission equipment. After the shrink-film is cut by the cutter equipment, a piece of the shrink-film will be pulled down by the label pulling rollers and the second guide pulleys and the shrink-film will be wrapped on the surface of the bottles or cans. Then the conveying equipment will convey the bottles and cans toward to the next equipment and making the shrink film and the bottles or cans be shrunk packaging completely.

The purpose of the present invention is to provide a heat-shrinking apparatus for shrink labels which is capable of uniformly heat shrinking a shrink label covering a portion or the entirety of an article, and which is capable of completing heat shrinking in a state in which water drops are not deposited on the article and the surface of the shrink label. Accordingly, the present invention is provided with: a heat treatment chamber (2) having, provided therein, a steam discharge unit (12) for discharging superheated steam in order to heat shrink a cylindrical label (L) fitted to a container (PC), and a heated air blowing unit (14) for causing deposited water drops to evaporate by blowing heated air on the container (PC) after the cylindrical label (L) has been heat shrlUlk; a superheater (22) which heats steam generated by a steam boiler (20), to generate the superheated steam; a preheating lUlit (27) which uses the surplus steam inside the heat treatment chamber (2) to preheat air used to generate the heated air; a heated-air-generating heat exchanger (15) which uses steam to heat the preheated air to a prescribed temperature; and a condensing heat exchanger (31) for condensing the surplus steam.

Food preservation can include depositing dry ice and food within packaging. The packaging can include a flexible liner defining a wall aperture and an internal chamber. The internal chamber can receive the deposited dry ice and food and have an internal atmosphere. The packaging can include a check valve mounted to the flexible liner and covering the wall aperture. The check valve can be configured to occupy: (i) a closed state blocking fluid communication between the internal chamber and ambient via the wall aperture and (ii) an open state enabling fluid flow from the internal chamber, through the wall aperture, and into ambient.

Cleanup kits including both wet wipes and dry wipes. In accordance with a first example, a cleanup kit includes a first dispenser containing wet wipes and having a first accessible opening to allow the wet wipes to be dispensed therethrough. The cleanup kit also includes a second dispenser containing dry wipes and having a second accessible opening to allow the dry wipes to be dispensed therethrough. The cleanup kit also includes a carrying handle projecting upwardly from the first and second dispensers and heat sealed to both the first dispenser and the second dispenser to couple the first and second dispensers together. The first and second dispensers are discrete dispensers having separate housings and separate lids.
