From the hard packing gradually toward lighter, more environmentally friendly flexible packaging
Modern food packaging not only provides physical protection for food and its contents, but also helps to extend shelf life, provide product information, and present a brand image that is more convenient to use each time. Compared to other packaging materials and forms, such as glass, metal and hard plastic packaging, soft plastic packaging is more environmentally friendly, saving raw materials and transportation costs, so as to better meet the needs of the modern packaging industry.
Asia-Pacific will be the fastest growing consumer packaged goods market in the future, according to research firm Smithers Pira.
PacXpert ™ is the industry’s most advanced packaging technology. It features a unique lightweight design and an ergonomically designed durable handle for precise dumping. When unpacked, the PacXpert ™ can be flat and easy to store and transport . While it is called flexible packaging technology, the PacXpert ™ package stays firmly in place, either standing or side-by-side, and provides excellent storage performance. Packed with PacXpert ™ technology also has a large shelf display space, attract more consumer’s attention, so that it has the intention to buy.
In addition, PacXpert ™ technology can bring considerable environmental benefits. It not only minimizes the waste of packaging contents, but also reduces raw material consumption and improves product-to-package ratio. In addition to being sought after by customers, the PacXpert ™ technology since 2013, the global packaging industry’s eight strength awards in the bag.
PacXpert ™ flexible packaging technology has been well received since the advent of Europe, to Latin America, from Latin America to Asia Pacific, PacXpert ™ gradually in the global set off a new trend of flexible packaging. With PacXpert ™ technology taking root in China, PacXpert ™ technology will also drive the Chinese packaging industry toward a lighter, greener, and more flexible package from rigid to hard packaging, which will undoubtedly open up a broader range of applications.
Food composite packaging film tends to multi-functional, lightweight
In the functional food packaging materials, China’s R & D and production capacity is still relatively weak, the future food industry on the high barrier, anti-cooking, anti-UV, dark, antibacterial, breathable, anaerobic functional membrane needs will continue to increase, But also to the light of the development trend.
ExxonMobil has introduced two new grades, Exceed ™ XP, to further expand its product range at K in 2016. These new grades are suitable for shrinking flexible packaging and food composite packaging, providing significant performance advantages for film processors and end users.
Since its launch, Exceed has been well received by the market, and its customers reflect the new level of product performance. These new grades reinforce this positive impact. Exceed XP 6026 and Edge 6050 have excellent processing properties, providing greater toughness, resistance to rubbing, heat-sealing properties, balanced shrinkage and good optical properties. For the processor, the high melt strength of these polymers allows for higher bubble stability and increased yield.
Food grade films (including size packs) from Exceed’s XP have excellent toughness and heat-seal properties to help brands protect frozen or dried food, meat and cheese products from production to consumption. Edge’s XP melt strength and toughness can be maintained while maintaining high performance film thickness. Processors can take advantage of the extraordinary performance and processability of these Exceeded XP grades to simplify product inventory and reduce costs.
With the public to reduce food waste and extend the shelf life of products increased awareness of food flexible packaging barrier film demand began to show a continuous upward trend. Today, most barrier film products are often produced by coextrusion through a blown film line, often with seven, nine or eleven layers. Polyamide 6 (PA6) has good barrier properties and mechanical strength, is the production of film-grade food packaging film ideal material. However, the high crystallization rate of polyamide 6 limits its processing window. As a result, processors need to make concessions in terms of production efficiency or improve their processability by mixing polyamide 6 with a special amorphous polyamide or polyamide copolymer, but this will give the film a cost effective advantage Greatly reduced.
this problem. This highly cost-effective advanced technology effectively combines barrier properties, printability, heat-sealability and impact resistance in a variety of combinations. Compared to conventional polyamide 6, Akulon® XS has a much slower rate of crystallization in the vesicles, giving the processor more room to maneuver in processing conditions to retain polyamide 6’s unique barrier and / Mechanical properties at the same time, more convenient and more efficient production for food flexible packaging film.
Akulon® XS not only has good mechanical strength, puncture resistance and barrier properties, but also can produce thinner film, bring quality and cost advantages, reduce waste.
In addition, EVOH as a high barrier material, its gas barrier, transparency, gloss, mechanical strength, stretchability, abrasion resistance, cold resistance and surface strength are very excellent. In the food packaging, EVOH plastic containers can replace glass and metal containers. Kuraray in 2016 chinaplas exhibition brought EVOH high barrier resin, can provide excellent gas barrier properties, chemical resistance, can be used in multi-layer structure.
Biological packaging and biodegradable packaging prospects
Consumers are increasingly concerned about environmental protection, how to reduce the use of fossil products from the source has become a topic of concern to enterprises. Among them, bio-based packaging materials become an important choice.
Not long ago, Tetra Pak launched the world’s first to obtain the highest level of certification of sterile paper packaging – using biomass plastic, equipped with 30 mm lightweight cover 1 liter Tetra Pak aseptic packaging. The new package of plastic film and open the lid by the sugar cane extract polymerization, together with the cardboard, the packaging of renewable raw materials ratio reached 80% or more, and by virtue of the four-star certification.
In a separate independent life-cycle analysis conducted by the IVL Swedish Environment Institute, the new packaging has a 17% lower carbon footprint than standard packaging. A 1-liter Tetra Pak Aseptic package with a 30mm lightweight lid and a 30mm lightweight lid is available worldwide and customers can switch to new packaging without additional capital investment.
NatureWorks launched its Ingeo biopolymer at CHINAPLAS in 2016 and exhibited a new high-barrier flexible packaging film made with Ingeo by Italian metalvuoto, which is specifically designed for the preservation of processed foods. This is the first time Ingeo has been used in the field of processed food packaging bags with long shelf life.
NatureWorks Extracts Glucose from Corn Starch As a raw material for the production of Ingeo, the carbon and other elements of these natural sugars are transformed into a range of different Ingeo products by fermentation, separation and polymerization processes. It is widely used in food hard packaging, such as disposable tableware, yogurt, and food flexible packaging.
Ingeo is the world’s first low-carbon functional material, with plants rather than oil, 100% from the annual renewable and resource-rich plant material. The current use of corn starch is the first generation of transitional raw materials, the future bypass the agricultural steps, the carbon dioxide or methane directly converted to green substrate, will be NatureWorks company development direction.
Ingeo products have received food contact compliance in many parts of the world and are a degradable material for municipal or industrial composting equipment. With environmental advantages and functional advantages, can reduce greenhouse gas emissions, reduce petrochemical energy consumption, while maintaining the taste of food aroma performance.
Packaging materials are mostly one-time products. In order to reduce the impact of packaging waste on the environment, waste reduction of plastic packaging has become one of the development direction. In the process of reduction, biodegradable materials play a leading role. With the improvement of environmental laws and regulations, as well as consumer awareness of environmental protection, the domestic biodegradable plastic packaging market is also expanding, “thirteen” period of biodegradable materials will usher in more opportunities for development.
According to ASD’s latest research report shows that 2013-2019 biodegradable plastic packaging market demand to maintain double-digit annual growth rate, by 2019 the global market value of biodegradable plastic packaging will be more than 8.415 billion US dollars. The report predicts that food and beverage packaging will be the main application of biodegradable plastics, polylactic acid and starch-based plastics will continue to dominate the biodegradable plastic packaging market for food packaging biodegradable plastics accounted for more than 70%.
