20080220134 | Barrier Submersion Cooking Pouch and Basket - A system and method for barrier submersion cooking comprising a thin walled plastic cooking pouch for receiving a food item effectively dimensioned such that when placed into a hot liquid cooking medium a vent remains above a top surface of the liquid cooking medium and a rack for lowering the vessel into the liquid cooking medium to an effective depth such that the food item received by the pouch is below the top surface of the liquid cooking medium and the vent is above the top surface of the liquid cooking medium. The pouch is formed of food grade pliable polymer film having a melt temperature above that of a temperature used in conventional hot oil frying processes, a heat transfer rate of an effective value to substantially instantaneously transfer heat from the liquid cooking medium to create an effective frying temperature upon the food item, and a pliability such that the pouch will collapse on itself when exposed to hydrostatic pressures when submerged within the liquid cooking medium, thereby effectively transferring heat to all food item surfaces. | 09-11-2008 |
20090169693 | Interior-mountable pressure relief valve - An interior-mountable pressure relief valve for packages containing food products such as coffee that normally tend to out-gas. The relief valve of the present invention can be made by thermoforming a pocket of a barrier type of semi-rigid film that has a heat seal membrane on one side. An indent can be made in the bottom of this pocket to receive a filter medium that covers an aperture in the bottom of the pocket. The filter medium can be heat-staked to the pocket. A pressure relief valve known in the art containing a base layer, a pair of rails and a flexible membrane can be placed in the pocket. This valve and pocket assembly can be can be treated with a mesh membrane that is heat sealable to the seal side to prevent disassembly or contamination. The product can then be wound on a level wound spool for shipping to an end user. The end user can take the carrier tape and dispense it into a single piece dose and then heat seal the carrier to the inside wall of the package. | 07-02-2009 |
20100055276 | GAS PERMEABLE MEMBRANES - Disclosed is a multilayer structure comprising a layer of humidity-dependent composition having a ratio of wet cup permeance to dry cup permeance greater than 10 and a layer of crystallizable polymer sufficiently permeable to oxygen, carbon dioxide and water vapor, exhibiting an increase in permeability to at least one of oxygen and carbon dioxide by a factor of at least 2.5 over a temperature range of 10° C. between 0° C. and 40° C. Also disclosed are packaging materials comprising the multilayer structure and methods for storing respiring materials using the packaging materials. | 03-04-2010 |
20100092634 | METHOD FOR INCREASING THE SHELF LIFE OR AGRICULTURAL PRODUCTS WHICH PRODUCE ETHYLENE, DURING TRANSPORT, SALE, PRESENTATION AND/OR STORAGE - The present invention relates to a method for increasing or influencing the shelf life of agricultural products which produce ethylene during transport and/or storage. In the method, the products are transported, sold, presented, and/or stored in packages made of corrugated cardboard ( | 04-15-2010 |
20100247725 | CONTAINER FOR RESPIRING PRODUCE - The present invention relates to the use of a packaging material in the construction of a container for respiring produce, wherein the packaging material consists of a polyether-ester block copolymer or a blend of polyether-ester block copolymers and which packaging material has all of the following properties: a) permeability for oxygen is at least 40 cc.mm/m2.day.atm at 10° C. b) permeability for carbon dioxide is at least 600 cc.mm/m | 09-30-2010 |
20150044341 | CONTAINER FOR PRESERVATION OF PERISHABLE FOOD ITEMS - A container for preserving food items includes a sidewall extending from a sidewall base, the sidewall defining an open interior space and a rim of the sidewall defining an opening in the container, the opening providing access to the open interior space. The container is constructed of an organic cotton fabric having a density of about 6-10 ounces per square yard (oz./sq. yd.). | 02-12-2015 |
20150147449 | METHOD AND SYSTEM FOR PROCESSING MEAT PRODUCTS IN A MODIFIED ATMOSPHERE - A method and system for wrapping meat in containers is provided. The method and system provide a modified atmosphere, other than that which exists as standard air, to a container such that a final sealed product contains an internal volume or atmosphere of modified gas. In-line processing features dispense the desired modified gas such that minimal interruption is provided in an automated or partially automated packing operation. | 05-28-2015 |
20150327590 | COMPOSITIONS AND METHODS FOR IMPROVED PACKAGING AND STORAGE OF DRY FOODSTUFFS - Provided herein is a degassing valve for a foodstuff product including a valve body, a one-way valve element positioned on the valve body, and a filter associated with said valve body wherein the filter is configured to facilitate the passage of a gas. The gas may be selected from the group consisting of carbon dioxide, oxygen, nitrogen, and methane. Additionally, the gas may be a longer molecular chain gas that comprises the aroma of the product. The filter of the valve body may include activated charcoal, an activated charcoal mixture or a combination thereof. In some embodiments, the foodstuff product comprises breadcrumbs, spices, or other flavorful dry foods, the aroma(s) of which can provide an important marketing benefit. | 11-19-2015 |
