Amcor and Plantic Technologies (both from Australia) have teamed up to develop biodegradable, flexible plastic packaging for confectionary. Plantic will provide its patented material, a plastic created from plants that dissolves rapidly on contact with water. Plantic is based on corn flour, a renewable and biodegrad-... 

Cheese products generally must be maintained under refrigeration using closed flexible plastic, or plastic cups or tubs for packaging. Ice cream packaging is generally minimal, ie, lacquered or polyethylene extmsion-coated paper-board cartons, molded plastic tubs, or spinal wound composite paperboard tubs or cartons. 

Example of an HACCP System. The HACCP system can be used to ensure production of a safe cooked, sHced turkey breast with gravy, which has been vacuum packaged in a flexible plastic pouch and subjected to a final heat treatment prior to distribution (37). Raw turkey breasts are trimmed, then injected with a solution containing sodium chloride and sodium phosphate. Next, the meat is placed into a tumbler. After tumbling, the meat is stuffed into a casing, placed onto racks, and moved into a cook tank, where it is cooked to an internal temperature of at least 71.1°C (160°F). After... 

Table I shows the chemical composition limits of various aluminum alloys presently used for packaging applications (3). In general, these alloys have good corrosion resistance with most foods. However, almost without exception, processed foods require inside enameled containers to maintain an acceptable shelf life (4, 5). Moreover, when flexible foil packages are used for thermally processed foods, the foil is laminated to plastic materials that protect it from direct contact with the food and also provide heat sealability as well as other physical characteristics (6,7).

Although glass containers are very suitable for Hb packaging, flexible plastic containers constructed from materials such as poly(ethylene-vinyl acetate) (EVA) are most widely used. The plastic packaging material must be carefully selected. Hemoglobin, like other proteins, is lipophilic and can facilitate extraction of low molecular weight lipophilic substances, such as the plasticizers used in poly(vinyl chloride) containers. 

The U.S. Environmental Protection Agency issued a final rule banning the use of CFC s in flexible plastics and packaging foams, among other uses, after February 15, 1993. Exceptions are CFC-11 and CFC-13 which can be used, temporarily, in mold release agents and the production of plastic and elastomeric materials. However, in 1994, no CFC s will be allowed in flexible foams in the U.S., and a tax will be levied on other CFC uses. Total CFC phaseout is mandated in the U.S. for 1995. 

This standard specifies a procedure for determining the dynamic cushioning performance of cellular rubber materials and rigid and flexible plastics by measuring the peak deceleration of a mass when it is dropped on a test piece. The test is intended primarily for quality assurance. However, since this type of test is also used to obtain design data notes are given in Annex A to assist in this objective. The method is applicable solely to packaging materials. 

Food packaging is undergoing enormous changes due to the shift in consumer interest towards convenience foods. Among food packaging materials, the use of plastics is expected to increase by 55% by 1990 (1). The market share of flexible and rigid plastic packaging is expected to increase from 19 billion to 44 billion by the year 2000 (2). ... 

Laminates of foil, paper and used in milk-type cartons (LDPE) for a variety of foods and drinks. Some HDPE used in extrusion coatings over flexible foil packages either as a glue layer between paper on plastics film and aluminum foil or as a heat-seal layer...
