Comparing Optimum Barrier Variables of Aluminium and MPET Foil Based Laminates for Coffee Packaging RESEARCH ARTICLE Comparing Optimum Barrier Variables of Aluminium and MPET Foil Based Laminates for Coffee Packaging Abhishek Dutta Dr. Gautam Dutta Asian Institute of Technology Indian Institute of Foreign Trade [email protected] [email protected] ABSTRACT The barrier property variables for Aluminum based laminates, both under flexed and un-flexed condition, were compared with that of MPET based laminates in order to understand comparative suitability of the later for coffee packaging. Keeping the expected shelf life condition of 180 days the different barrier property variables of the sample MPET and Aluminum based laminates, at the optimality condition, were found out. At the optimum condition, Oxygen transfer rate (OTR) under flexed condition is marginally more for MPET based laminates. However, Aluminium laminates in flexed condition allowing moisture transfer (WVTR) at the rate 24.32 percent stronger than MPET based laminates which may not be good for coffee packaging.

Coloured plain packs (white, green, light blue, red) without a brand name, any brand descriptors or tar or nicotine levels, were identified by almost all smokers as signalling product strength. Consistent with past research the removal of branding from packs reduced the attractiveness and promotional appeal of the pack, with dark brown ‘plain’ packs perceived as more unappealing than light brown and dark and light grey packs by all groups.

    European Aluminium Foil Association NO. 55 | SPRING 2019 Winning entries focus on more convenience and a better environment The most important competition for innovation and new technological advances in aluminium foil, the Alufoil Trophy 2019, once again attracted a strong field of entries. In total nine awards were made across the five categories, including a dis- cretionary award for overall excellence for one outstanding product. The Alufoil Trophy is an an- nual event, organised each year by the European Aluminium Foil Association (EAFA). The judges, led this year by Laura Fernandez, se- nior packaging technologist at Marks & Spencer, noted strong social elements running through entries this time, particularly in terms of conve- nience for the consumer and social or environ- mental aspects of the product development. One example of these themes is an alufoil lid with the capability to emboss braille – offering infor- mation to shoppers with poor vision.

  • Adhesion of Aluminium Foil to Coatings – Stick with It
    Adhesion of Aluminium Foil to Coatings – Stick With it Günter Schubert Hydro Aluminium Deutschland GmbH R&D, Georg von Boeselager-Strasse 21, 53117 Bonn, Germany ABSTRACT Aluminium foil is widely regarded as the most effective barrier material in flexible packaging, giving almost perfect protection against light and suppressing any transport of matter. Foil is usually converted to flexible packaging laminates by traditional converting processes, such as lacquering or 2-component-adhesive lamination, but more and more extrusion coating and extrusion lamination are being used. Almost all aluminium is put through an annealing process, to produce an appropriate surface, which is as good and homogeneous as possible with regard to unwinding properties (at high speed), wettability, adhesion and chemical resistance. The effects on adhesion performance as a result of replacement of traditional sealants and adhesives by extrusion coatings are described for selected types of packages and packaged goods. Aspects relating to the foil’s surface and coatings’ barrier will be discussed. 1. INTRODUCTION Looking at flexible packaging, there is a distinct trend towards the use of extrusion coating and extrusion lamination for converting aluminium foil. A number of substantial benefits can be gained from manufacturing without solvents, achieving high line-speed, saving space for drying channels, saving on investment for solvent recovery equipment or saving storage space for crosslinking adhesives and cutting lead times. Requirements on packaging machinability, especially seal performance are usually mastered, but major effects such as the interactions between package and the filled good are often forgotten. The main reason for using aluminium foil in flexible packaging lies in the need to completely suppress migration or permeation through the package and shield the packaged good from the environment in the most suitable way.

  • Food in Aluminium Packaging Materials and Foil Containers in Use
    Food in aluminium packaging materials and foil containers in use for microwave ovens Experimental study of safety, efficiency and evenness of cooking In an extensive study of efficiency, safety and heating properties of food-packaging materials made of aluminium foil in microwave ovens, the Fraunhofer Institute for Process Engineering and Packaging has confirmed the results of previous studies conducted by other research institutes: the use of aluminium foil packaging materials in microwave ovens is safe when the general instructions for use are observed. Foods packaged in aluminium trays or in plastic containers with a laminated alufoil lid are best suited for cooking in microwave ovens and can be enjoyed without any safety reservations. A broadly arranged series of tests focussed in particular on the parameters safety, efficiency and evenness of cooking. Numerous tests as a basis A total of over 200 microwave-oven tests with food in a broad variety of aluminium foil containers were conducted. Four different microwave ovens were used for each of the experiments. The tests were carried out on aluminium trays containing tapwater, egg batter, deep-frozen lasagne and minced meat. Other tests were also performed using plastic beakers and dishes containing noodle soup or children’s meals and sealed with aluminium foil or composite- material aluminium lids. The researchers carried out all application-oriented tests with the microwave ovens switched to full heating power. The result: not one single oven was damaged, no user was injured. Not one case of sparking in the microwave ovens was observed when the instructions were properly heeded. The tests were carried out under the general condition of use that only one tray was used for each heating run and that this tray was placed in the middle of a nonmetallic oven turntable without any contact with the walls.
