FDA Compliance and Printing Inks Often Printers Have Questions
FDA Compliance and Printing Inks Often Printers have questions concerning the Food and Drug Administration (FDA) and compliance of the inks used to print on food packaging applications. The FDA permits the use of inks (e.g. solvent base, water base and UV) as components of food packaging under certain conditions. Several items must be understood before one can determine if a printing ink is suitable for use on food packaging applications: “Direct Food Additives” are substances directly and intentionally added to foods, including, but not limited to, ingredients, preservatives, colors and stabilizers. “Indirect Food Additives” generally refer to substances that are not intended to, but can become, components of food as a result of use in articles that contact food (e.g. ink on food packaging applications). Both “Direct and Indirect Food Additives” require complex petitions and filings with the FDA that can be very costly, burdensome and time consuming. Nazdar inks are not designed to be and are not approved as Direct or Indirect Food Additives. However, if an ink on food packaging applications is not expected to become a component of the food under its intended conditions of use, it is not a food additive by definition and, therefore, may be used without the need to obtain any FDA clearance. A properly conducted migration study is considered to be a sound basis for concluding that the substance is not a food additive. This study should be performed in accordance with FDA’s guidance document, entitled; Preparation of Food Contact Notifications and Food Additive Petitions for Food Contact Substances: Chemistry Recommendations https://www.fda.gov/regulatory-information/search-fda-guidance-documents/guidance-industry- preparation-premarket-submissions-food-contact-substances-chemistry Another method of concluding that a substance is not a food additive is the use of a functional barrier.

Extrusion Foaming of Bioplastics for Lightweight Structure in Food Packaging
EXTRUSION FOAMING OF BIOPLASTICS FOR LIGHTWEIGHT STRUCTURE IN FOOD PACKAGING A thesis submitted for the degree of Doctor of Philosophy by Sitthi Duangphet School of Engineering and Design Brunel University December 2012 i Abstract This thesis reports the systematic approaches to overcome the key drawbacks of the pure PHBV, namely low crystallisation rate, tensile strength, ductility, melt viscosity, thermal stability and high materials cost. The physical, mechanical, thermal, and rheological properties of the pure PHBV were studied systematically first to lay a solid foundation for formulation development. The influence of blending with other biopolymers, inclusion of filler, and chain extender additives in terms of mechanical properties, rheology, thermal decomposition and crystallization kinetics were then followed. Creating lightweight structures by foaming is considered to be one of the effective ways to reduce material consumption, hence the reduction of density and morphology of PHBV-based foams using extrusion foaming technique were studied comprehensively in terms of extrusion conditions (temperature profiles, screw speed and material feeding rate) and the blowing agent content. The material cost reduction was achieved by adding low-cost filler (e.g. CaCO3) and reduction of density by foaming. The thermal instability was enhanced by incorporation of chain extender (e.g. Joncryl) and blending with a high thermal stability biopolymer (e.g. PBAT). The polymer blend also improved the ductility. Adding nucleation agent enhanced the crystallization rate to reduce stickiness of extruded sheet. The final formulation (PHBV/PBAT/CaCO3 composite) was successfully extruded into high quality sheet and thermoformed to produce prototype trays in an industrial scale trial. The effect of the extrusion conditions (temperature profiles, screw speed and material feeding rate) and the blowing agent content are correlated to the density reduction of the foams.

Radiation Processing for Safe, Shelf-Stable and Ready-To-Eat Food
IAEA-TECDOC-1337 Radiation processing for safe, shelf-stable and ready-to-eat food Proceedings of a final Research Co-ordination Meeting held in Montreal, Canada, 10–14 july 2000 January 2003 The originating Section of this publication in the IAEA was: Food and Environmental Protection Section International Atomic Energy Agency Wagramer Strasse 5 P.O. Box 100 A-1400 Vienna, Austria RADIATION PROCESSING FOR SAFE, SHELF-STABLE AND READY-TO-EAT FOOD IAEA, VIENNA, 2003 IAEA-TECDOC-1337 ISBN 92–0–100703–5 ISSN 1011–4289 © IAEA, 2003 Printed by the IAEA in Austria January 2003 FOREWORD The increasingly busy lifestyles of populations in many countries have driven the demand for safe, convenient and ready-to-eat food. Traditional food processes such as drying, canning or refrigeration offer a partial solution to this demand as the sensory quality of such food may be significantly affected or the products may be contaminated by pathogenic bacteria during preparation. For developing countries, safe shelf-stable food without the need for refrigeration would offer advantages. In addition, the increasing number of immuno-compromised populations in many countries requires a new approach to food safety to meet their needs. Irradiation offers a potential to enhance microbiological safety and quality of food through shelf-life extension. The benefits of irradiation as a sanitary treatment of many types of food are well known, some of which are applied commercially in several countries. Little data were available, however, on the effect of irradiation on minimally processed food and composite food including prepared meals. A Co-ordinated Research Project (CRP) on the Development of Safe, Shelf-Stable and Ready-to-Eat Food through Radiation Processing therefore was implemented by the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture in 1996 to evaluate the role of irradiation for such food.

Amcor/Bemis: Flexible Medical Packaging Overlaps Draw DOJ Scrutiny
Vol. 6 No. 400 November 9, 2018 Amcor/Bemis: Flexible Medical Packaging Overlaps Draw DOJ Scrutiny Deal Update DOJ staff attorneys investigating Amcor’s proposed $5.2 billion purchase of packaging rival Bemis (BMS) have keyed in on two healthcare product lines in which the merging parties overlap, sources familiar with the matter said. The deal would combine two of the three dominant producers of coated TyVek, a breathable medical packaging film that can be sterilized. The tie-up would also join two significant U.S. converters of vented medical bags. DOJ staff has interviewed industry participants about these overlaps as recently as two weeks ago, the sources said. Given market shares and competitive dynamics, the merging firms’ overlap in coated TyVek raises a more significant antitrust issue than the vented medical bag overlap, industry sources said. Reflecting this dynamic, sources said that over time, DOJ interviews have become more focused on coated TyVek, to the exclusion of vented medical bags. The merging parties also overlap in food packaging, but these markets are generally fragmented and characterized by a more robust competitive environment than their medical counterparts. Amcor and Bemis, who announced their deal on August 6, have not disclosed the receipt of a DOJ second request. Spokespeople for Amcor and the DOJ declined to comment. Bemis did not respond to requests for comment. Coated flexible medical packaging. Amcor and Bemis both produce various types of sterile flexible medical packaging, which is sold to medical device manufacturers to protect medical equipment and devices ultimately sold to hospital groups and doctors.

Food Packaging Made from Recycled Paper and Board
Page 1 of 3 Food Packaging made from Recycled Paper and Board Monitoring in Europe of packaging and foods has identified mineral oil contamination in a range of packaged foods. Mineral oils are widely used, and end up in foodstuffs by various routes. Since then, almost all sectors of the food industry as well as laboratories and supply industry have been concerned with the presence of mineral hydrocarbons and investigated into their origin. As a result, industry has gained a comprehensive understanding of the different sources of mineral oil contaminations.1 Many measures for the reduction of the transfer and occurrence of undesired mineral oils that have already been taken show objectively measurable success. There are many different routes by which contamination of foodstuffs with mineral oils can occur. Food packaging has been identified as one of these sources. EuPIA members have long offered mineral oil-free inks to be applied to the non-food side of packaging, and recommend that only these inks are used for these applications. Mineral oils can, however, migrate from recycled paper and board used for food packaging. In several EU member states the food packaging chain was called to take measures such that levels of mineral oil in foodstuffs are reduced. The European Commission has issued a recommendation2 on the monitoring of mineral oil hydrocarbons in food and in materials and articles intended to come into contact with food in 2017. In Germany the BMEL has drafted a legislation aimed at restricting mineral oil in food contact materials made from recycled paper and board.

Packaging Films and Meat Color
PACUGIMS FILMS AND iVIE:AT COLO3” DUAXZ 0. VESTdRBZRG UNION CARBIDE: CORPORATION The subject for this morning’s talk is listed as packaging films and meat color, I have taken the liberty to broaden the area to be discussed since it is very difficult to pick out one quality factor and relate it alone to packaging films, I would rather title the talk as packaging films and meat quality. It is true that the color of meat is a very important factor in the marketability of a meat item but probably less important than other factors which can affect the quality of a product being sold by a manufacturer to his customers. It is true that in many cases meat color can reflect how the meat product has been treated during the normal manufacturing process and in the distribution and handling of the product to the display case where it is finally sold. On the other hand, one only has to look in the meat display case of the local supermarket to see the number of sophisticated packages and packaging techniques which have been developed through the cooperation of film manufacturer, equipment manufacturer, and meat packer to protect the quality of the meat item to the consumer. I have divided ny talk into three general areas, I plan to first discuss the requirements placed on the packaging material by the type of meat product being packaged, specifically fresh retail meat cuts, processed meats, and primal and subprimal neat cuts. Secondly, I will discuss the procedures available to film manufacturers to build in required filn properties for packaging the various types of meat.

Biodegradable Packaging Materials from Animal Processing Co-Products and Wastes: an Overview
polymers Review Biodegradable Packaging Materials from Animal Processing Co-Products and Wastes: An Overview Diako Khodaei, Carlos Álvarez and Anne Maria Mullen * Department of Food Quality and Sensory Science, Teagasc Food Research Centre, Ashtown, Dublin, Ireland; [email protected] (D.K.); [email protected] (C.Á.) * Correspondence: [email protected]; Tel.: +353-(1)-8059521 Abstract: Biodegradable polymers are non-toxic, environmentally friendly biopolymers with con- siderable mechanical and barrier properties that can be degraded in industrial or home composting conditions. These biopolymers can be generated from sustainable natural sources or from the agri- cultural and animal processing co-products and wastes. Animals processing co-products are low value, underutilized, non-meat components that are generally generated from meat processing or slaughterhouse such as hide, blood, some offal etc. These are often converted into low-value products such as animal feed or in some cases disposed of as waste. Collagen, gelatin, keratin, myofibrillar proteins, and chitosan are the major value-added biopolymers obtained from the processing of animal’s products. While these have many applications in food and pharmaceutical industries, a sig- nificant amount is underutilized and therefore hold potential for use in the generation of bioplastics. This review summarizes the research progress on the utilization of meat processing co-products to fabricate biodegradable polymers with the main focus on food industry applications. In addition, the factors affecting the application of biodegradable polymers in the packaging sector, their current industrial status, and regulations are also discussed.
