  • 4 Active Packaging in Polymer Films M.L
    4 Active packaging in polymer films M.L. ROONEY 4.1 Introduction Polymers constitute either all or part of most primary packages for foods and beverages and a great deal of research has been devoted to the introduction of active packaging processes into plastics. Plastics are thermoplastic polymers containing additional components such as antioxidants and processing aids. Most forms of active packaging involve an intimate interaction between the food and its package so it is the layer closest to the food that is often chosen to be active. Thus polymer films potentially constitute the position of choice for incorporation of ingredients that are active chemically or physically. These polymer films might be used as closure wads, lacquers or enamels in cans and as the waterproof layer in liquid cartonboard, or as packages in their own right. The commercial development of active packaging plastics has not occurred evenly across the range of possible applications. Physical processes such as microwave heating by use of susceptor films and the generation of an equilibrium modified atmosphere (EMA) by modification of plastics films have been available for several years. Research continues to be popular in both these areas. Chemical processes such as oxygen scavenging have been adopted more rapidly in sachet form rather than in plastics. Oxygen scavenging sachets were introduced to the Japanese market in 1978 (Abe and Kondoh, 1989) whereas the first oxygen-scavenging beer bottle closures were used in 1989 (see Chapter 8). The development of plastics active packaging systems has been more closely tied to the requirements of particular food types or food processes than has sachet development.

The enzymes were incorporated into a dispersion coating formulation applied onto a food- in coatings and films for packaging board using conventional laboratory coating techniques. The oxygen- reducing enzymes investigated included a glucose oxidase, an oxalate oxidase active packaging and three laccases originating from different organisms. All of the enzymes were successfully incorporated into a coating layer and could be reactivated after drying. For at least two of the enzymes, re-activation after drying was possible not only Kristin Johansson by using liquid water but also by using water vapour. Re-activation of the glucose oxidase and a laccase required relative humidities of greater than 75% and greater than 92%, respectively. Catalytic reduction of oxygen gas by glucose oxidase was promoted by creating 2013:38 an open structure through addition of clay to the coating formulation at a level above the critical pigment volume concentration. For laccase-catalysed reduction of oxygen gas, it was possible to use lignin derivatives as substrates for the enzymatic reaction.

  • Active and Intelligent Packaging
    Paper No.: 12 Paper Title: FOOD PACKAGING TECHNOLOGY Module – 25: Active and Intelligent Packaging 1. Introduction: For a long time packaging also had an active role in processing and preservation of quality of foods. Variations in the way food products are produced, circulated, stored and sold, reflecting the continuing increase in consumer demand for improved safety, quality and shelf- life for packaged foods are assigning greater demands on the performance of food packaging. Consumers want to be assured that the packaging is fulfilling its function of protecting the quality, freshness and safety of foods. Thus, advances in food packaging are both anticipated and expected. Society is becoming increasingly complex and innovative packaging is the outcome of consumers' demand for packaging that is more advanced and creative than what is currently offered. “Active packaging” and “intelligent packaging” are the result of innovating thinking in packaging. Active packaging can be defined as “Packaging in which supplementary constituents have been deliberately added in or on either the packaging material of the package headspace to improve the performance of the package system”. In simple terms, Active packaging is an extension of the protection purpose of a package and is commonly used to protect against oxygen and moisture. It permits packages to interact with food and environment. Thus, play a dynamic role in food preservation. Developments in active packaging have led to advances in many areas, like delayed oxidation and controlled respiration rate, microbial growth and moisture migration. Other active packaging technologies include carbon dioxide absorbers/emitters, odour absorbers, ethylene removers, and aroma emitters. On the other hand, intelligent packing can be defined as “Packaging that has an external or internal indicator to provide information about characteristics of the history of the package and/or the quality of the food packed”.

  • Active and Intelligent Packaging: Innovations for the Future
    1 Active and Intelligent Packaging: Innovations for the Future By Karleigh Huff Graduate Student Department of Food Science and Technology Virginia Polytechnic Institute and State University (Virginia Tech) Blacksburg, Va 2 Introduction Food packaging exists to make our lives easier. We need packaging to contain foods, protect foods from the outside environment, for convenience, and to communicate information to consumers about the food inside the package. Containment is the most basic function of a package. Even fresh produce, which is displayed unpackaged at the store, must be transported out of the store in some type of container. Packaging provides protection of food from adulteration by water, gases, microorganisms, dust, and punctures, to name a few. A food package communicates important information about the product, how to prepare it, and information about the nutritional content. Packaging also allows for consumers to enjoy food the way they want, at their convenience. Food packages can be geared toward a persons own lifestyle through designs like portability and single serving dishes. Although traditional packaging covers the basic needs of food containment, advances in food packaging are both anticipated and expected. Society is becoming increasingly complex and innovative packaging is the result of consumers© demand for packaging that is more advanced and creative than what is currently offered. Active packaging and intelligent packaging are the result of innovating thinking in packaging. Defining Active Packaging and Intelligent Packaging To understand what active and intelligent packaging have to offer the world of packaging, it is important to clarify what each phrase means. Active packaging is accurately defined as ªpackaging in which subsidiary constituents have been deliberately included in or on either the packaging material or the package headspace to enhance the performance of the package systemº (Robertson, 2006).

  • Packaging Insulation 101
    Packaging Insulation 101 Considerations for choosing the right material and construction for temperature controlled packaging Jean Bedard, VP of Cold Chain Operations, Mesa Labs Kevin Kohleriter, Marketing, Mesa Labs Choosing the right material and construction for temperature controlled packaging controlled temperature for construction and material right the Choosing How temperature controlled packaging works, types available, and how to choose the right one Packaging insulation is vital to combat energy losses during transportation and storage. Thermal Insulation material acts as a barrier preventing heat transfer between objects of differing temperatures. The same principle works for packaging containers as they do for building insulation. Insulation reduces unwanted heat flow between the product and the environment. Thermal Insulated packaging is indispensable for the safe transit of biodegradable and highly perishable food items, such as medicines, biotech, electronics, horticulture and chemicals. The purpose of which is to avoid deterioration in quality and efficacy. There are different types of thermal insulation materials available in the market today. Balancing between cost, weight, effectiveness, and environmental factors all weigh into the decision. Characteristics of a good packaging insulation material. The objective of a good insulation material is to effectively maintain product temperatures within permissible range and reduce the deterioration rate of a product during transit until it reaches the recipient. Depending upon the application, a good thermal packaging insulation material has the following relevant characteristics: high resistance to heat transfer by conduction, convection or radiation low cost low weight low moisture susceptibility ease of fabrication and transportation durability mechanical strength In packaging applications, any material that offers a high resistance to the transfer of heat by conduction, convection or radiation serves as a form of insulation.
