The process may Clamco 6800CS Side Sealer be accomplished by hand, or by using automatic or Intermittent motion, automatic side seal shrink wrapper semi-automatic packaging equipment. Creating a that offers exceptional return on investment. strong seal in the film is the first step. To achieve this, a hot knife or hot wire is pressed against the film to weld the seal together. The seal process has three variables: time, temperature, and pressure. Each may be adjusted to suit different film types. Once sealed in a film envelope, the package is passed through a heated shrink tunnel. When heated, the film softens and expands, and as the film cools it shrinks tight. The package exits the tunnel wrapped in a taught, secure, attractive film. There are several films from which you may Clamco 6700GLX Automatic L-Bar Sealer choose.

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. -

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.
