Plastics, which are indispensable in production and life, have a wide range of uses. Although traditional plastics have complete functions, they have caused many problems due to their poor degradability. With the development of environmental protection and science and technology, many chemical companies have developed new models. Bioplastics bring new experiences to people.
Cellulose-based materials
Eastman Chemical Company introduced Eastman TRĒVATM engineered bioplastics this year to meet the requirements for high performance and sustainable development.
According to Burt Capel, vice president and general manager of Eastman Specialty Plastics, approximately 50% of Bio-based TRĒVATM has the advantages of sustainability, end-use performance, design freedom, and brand differentiation.
According to Burt Capel, about half of the TRĒVATM materials are derived from cellulose in trees, which are derived from sustainably managed forests certified by the US Forest Stewardship Council (FSC) and contain no bisphenol A and phthalates.
TRĒVATM has excellent sustainability, safety benefits, end-use performance, and design and brand flexibility. It is ideal for the following applications: eyeglass frames, wearable electronics, headphones, and many other personal devices that come in direct contact with the skin. Electronic display applications such as housings and cases that can be viewed by consumers; electronic products, complex cosmetic packaging and other products with high design requirements and complex specifications; automotive interior parts requiring chemical resistance and aesthetics; and high requirements for sustainability and safety Other applications.
Expand Ingeo Bioplastics
With the single cup of coffee, the independent packaging of tea and soft drinks has become increasingly popular. How used coffee capsules are degraded in landfills has become an issue of increasing concern.
At CHINAPLAS 2017, NatureWorks demonstrated compostable coffee capsules, including films, rigid capsules, and non-woven technology for filtration, to meet drip irrigation and high pressure temperature requirements when using capsules, and maintain their composting properties.
Ingeo compostable capsule packaging
This compostable and degradable coffee capsule is a solution that NatureWorks has been working with for a number of years, working with compounding manufacturers, processors and coffee companies to continuously improve Ingeo.
In the process of R&D, the team also encountered many technical problems, such as how to make capsules that can meet the temperature, pressure and filtration requirements, but still maintain composting characteristics,” explains Mark Vergauwen, global director of the HardWorks Division of NatureWorks.
In addition to compostable degradable coffee capsules, Natureworks also features Ingeo transparent FFS dairy and dessert packaging. These FFS cups feature high transparency, high stiffness and less material than polystyrene (PS).
According to reports, China OEM Hangzhou Zhongya Machinery Co., Ltd. recently tested the processing of Ingeo sheets on its FFS machine. The Central Asian company said that the FFS packaging made of Ingeo material is excellent in barrier properties and maintaining food flavor. In polystyrene packaging.
Nature Works also unveiled a new high barrier film. The EarthFirst UL, developed on Ingeo, is an ultra-thin bio-based sealing film for flexible packaging that reduces the cost of the sealing film used. Environmental advantages.
Stefano Cavallo, Global Industry Director for Films and Cards, said: 'Ingeo replaces the inner layer of packaging materials, which can significantly reduce the weight of the package by up to 65%.' He explained that one of the main advantages of EarthFirst UL is its high rigidity and its replacement. Other materials, and good performance, light weight.
In addition, compared to LLDPE, EarthFirst UL can form excellent seals at a lower initial sealing temperature, and it has a high coloring capability, making it particularly suitable for bonding to PET, metPET, PPT, nylon and paper substrates. Effective barrier to oil, grease, thickness 9, 12 and 15 microns.
EarthFirst UL is said to be particularly suitable for food packaging using single pillow pouches, coffee brewing packages, triangular stand-up pouches, frozen foods and multi-walled bags.
Biomass filling material
China Xinda, a domestic polymer compound company, also brought a variety of innovative solutions for automobiles, 3D printing, rail transportation, food packaging, daily-use households, and so on at CHINAPLAS 2017.
Such as the application of Xinda biomass filling material for automotive interior ceiling safety handle, compared with pure polypropylene products, with light weight, high hardness, long service life, excellent mechanical properties and other characteristics. As the filler is a biomass, you can Reducing the consumption of petroleum resources and making it more environmentally friendly.
It is said that in the case of homogeneous mixing of materials, the product made of Xinda biomass filler has higher flame retardancy, and can reduce the weight of components by about 20%.
According to Ma Qingwei, Managing Director of China Xinda, Xinda has three major development priorities in the future, including lightweight automotive composites, R&D of bio-based plastics, and commercialization of 3D printing. Currently, the automotive industry accounts for more than 80% of China Xinda's business. It can be reduced to 50% by 2020.
