Martin Zikmund Brno, 2017 Organization  Aim of today To understand range of packaging materials, its history, current technology and future trends, get overview of packaging market, packaging in logistics, environmenal impact and how packaging have to be sustainable.  Agenda 8:00 – 8:45 Block 1 8:45 – 8:55 Break 8:55 – 9:40 Block 2 9:40 – 9:50 Break 9:50 – 10:20 Block 3 10:20 – 10:35 Questions Definition of Packaging  Packaging is the art, science and technology of preparing products for market  Packaging are processes and materials employed to contain, handle, protect, and/or transport an article  Packaging is the technology of enclosing or protecting products for distribution, storage, sale, and use  Packaging is a techno-economic function aimed at minimizing costs of delivery while maximizing sales. It providing presentation, identification, information and convenience for the product from the moment of production until it is used  Functions of Packaging: • contains, protects, preserves, transports, informs, and sells • attract attention, assist in promotion, provide machine identification, impart essential or additional information, and help in utilization Packaging is a coordinated system of preparing goods for transport, warehousing, logistics, sale, and end use History of Packaging  Constant movement of early humans at ancient times (nomadic hunters and gathers) forced them to construct devices for carrying and containing water, food, tools etc. Primitive man used vessels and containers made of natural materials in form of tree leaves, bamboo, lotus leaves, palm leaves, gourds, coconut shells, shells and animal skin.  Later on, as minerals, ores and chemicals were discovered, metals and pottery were developed leading to use of new materials including fabrics, ceramics, metals, lacquerware, wood ware, jade ware, and certain types of paper. History of Packaging Cont. • Glass packaging first begun to be used in 1500 B.C. in Egypt • Around 1200 B.C pots and mugs started to be made from molded glass • 300 B.C. Phoenicians invented the blow pipe starting production of transparent glass • 1889 patented “automated rotary glass manufacture machine“ • Mulberry tree barks were used in China in the 1st and 2nd centuries B.C. to wrap food • During the 8th century Chinese papermaking spread to the Islamic world • By the 11th century papermaking was brought to medieval Europe • 1817 the first commercial cardboard box produced in England, 200 years after China • The production of tin sheet was invented in Bohemia in 1200 A.C. • 1809 Napoleon Bonaparte requested a method to protect the army's food supply Nikolas Appert from Paris presented tinned can. A year later English man Peter Durant, earned the right to patent the cylindrical can • 1838 Alexander Parker - first artificial plastic to replace natural materials such as ivory • 1849 Charles Goodyear and Thomas Hancock developed a procedure that added elasticity to natural rubber. In 1851 hard rubber or "ebonite” has become commercial • 1870 New Yorker John Wesley Hyatt was given a patent for "celluloid” • 1907 Leo Hendrik Baekeland produced "Bakelite” History of Packaging Cont. Types of Packaging  Primary packaging (Sales packaging) A complete integral package for the end-user or the consumer. (e.g., a bottle or a can for fizzy drink)  Secondary packaging (Grouped packaging) Any packaging helping to group a number of sellable units (primary packaging); it may be removed from the product without affecting its characteristics. (e.g., the plastic packaging around 6 bottles of fizzy drink)  Tertiary packaging (Transport packaging) Any packaging enabling the safe handling and transport of a number of sellable units or grouped packaging, in order to prevent physical damage due to incorrect handling or transport (e.g., pallets or wooden crates). It does not include road, rail, ship or air containers.  Service packaging Any kind of primary, secondary or tertiary packaging that is used at the POS to consumers of goods or services, as well as any kind of packaging which is of the same type and which is used in the same way. (e.g., a bread bag at the baker’s; a paper wrapped around meat at the butcher’s) Packaging Design  Marketing function of Packaging (Displays)  Information function of Packaging (safety and legislative requirements)  Different Packaging bring added value  CAD systems to support Packaging design (e.g. ArtiosCAD)  World Design Organization (www.wdo.org)  Design Awards (e.g. reddot - http://en.red-dot.org/ ) Flexible packaging; $ 183bn; 22% Board; $ 262bn; 31% Glass; $ 60bn; 7% Rigid plastic; $ 180bn; 21% Metal; $ 117bn; 14% Others; $ 38bn; 6% Global Packaging Market 2015: $ 839 billion Source: Smithers Pira Market Data  External (Third Party) Market Data -> Market Index  EUWID – https://www.euwid.de/en/  S&P Global Platts - https://www.platts.com/  Bloomberg - https://www.bloomberg.com/markets Categories of Packaging  Paper based boxes (corrugated and solid board)  Plastic foils, bags, sacks, films  Pallets and wooden packaging  Bottles, glass packaging  Thermoformed trays  Foams  EPS & EPP  Beeboard (hexacomb)  Moulded pulp & Thermoformed Fiber  Drums, barrels, cans  Special packaging  Labels & Printings  Other packaging Solid board (Paperboard)  Solid board (carton) is produced in weights from 200 – 650 g/m2; it is multi-plyr paper board typically used for folding cartons  One or more coating layers are applied to improve whiteness, smoothness and gloss of paperboard usually by:  pigment, which could be china clay, calcium carbonate or titanium dioxide  an adhesive or binder as styrene-butadiene emulsions or starches and water  Grades of paper according DIN 19303 "Paperboard - Terms and grades„ Example: GC1 would be a "pigment coated", "virgin mechanical pulp" board with a "white reverse side".

(2000) Packaging Cost Trade-Offs with Other Logistics Activities (Lambert et al., 1998) Packaging Logistcs Cont.  Container utilization software – optimization depending on type of packaging and its possibility to stack  Proper packaging prevents damage  Overseas shipments – special requirements resist humidity (Silicagel, VpCi – Vapor Phase Corrosion Inhibitor, MCI – Migrating Corrosion Inhibitor)  Inflatable Cargo Bags - Prevent packages against unwanted movement in containers during transit  Air transportation requires special packaging resisting temperature and pressure losses during transit Truck Load Safety  ČSN EN 12195 – Load restraining on road vehicles – Safety: design of securing methods (blocking, lashing, and combinations) for securing of loads for surface transport by road vehicles or parts of them (lorries, trailers, containers and swap bodies), including their transport on vessels or by rail and/or combinations thereof  VDI 2700 - Securing of loads on road vehicles (German norm)  Use antislip pads, sheets, paper to increase friction to prevent package from movement on truck Stretch Film (Stretch Wrap)  Stretch wrap material is linear low-density polyethylene or LLDPE, which is produced by copolymerization of ethylene with alpha-olefins, giving rise to enhanced stretch film characteristics, particularly in respect of elongation at break and puncture resistance  Many films have about 500% stretch at break but are only stretched to about 100 – 300% in use. Once stretched, the elastic recovery is used to keep the load tight  Films from 10 – 23 microns are used providing security of load on pallet  Proper combination of stretch and thickness can be optimized  Testing according EUMOS 40509-2012: Test method for load unit rigidity Sustainable Packaging  Sustainable Packaging is the development and use of packaging which results in improved sustainability. This involves increased use of life cycle inventory (LCI) and life cycle assessment (LCA) to help guide the use of packaging which reduces the environmental impact and ecological footprint. It includes a look at the whole of the supply chain: from basic function, to marketing, and then through to end of life (LCA) and rebirth.  Sustainable packaging: A. Is beneficial, safe & healthy for individuals and communities throughout its life cycle B. Meets market criteria for performance and cost C. Is sourced, manufactured, transported, and recycled using renewable energy D. Optimizes the use of renewable or recycled source materials E. Is manufactured using clean production technologies and best practices F. Is made from materials healthy throughout the life cycle G. Is physically designed to optimize materials and energy H. Is effectively recovered and utilized in biological and/or industrial closed loop cycles Sustainable Packaging Cont.
