In the competitive landscape of the global food industry, the preservation of sensory qualities—specifically taste and aroma—has become the ultimate benchmark for quality. EVOH (Ethylene Vinyl Alcohol) granules have emerged as the cornerstone technology for achieving this. Unlike traditional plastics, EVOH is a copolymer of ethylene and vinyl alcohol, uniquely engineered to offer the lowest gas permeability among all flexible packaging materials.
The commercial significance of EVOH for Aroma Protection cannot be overstated. From the delicate notes of premium roasted coffee to the pungent essential oils in spices, the escape of volatile organic compounds (VOCs) leads to "flavor scalping" and product degradation. EVOH acts as a molecular shield, ensuring that the aromatic profile remains locked inside the package while preventing external odors from contaminating the contents.
Since its establishment in 1950, TPS Specialty Chemical Limited has always focused on innovation and development in the chemical industry. Headquartered in Argentina, after more than 70 years of development, TPS has grown into one of the leading companies in the global chemical industry. We have branches around the world, especially in Hong Kong, which has laid the foundation for our rapid growth in the Global market.
As a company with an international vision, TPS actively seeks in-depth cooperation with well-known local chemical companies in many countries and regions to jointly develop a series of innovative products with market competitiveness. In the Chinese mainland, TPS has set up the R&D center in Chongqing City to focus on the research and development of high-tech materials and successfully launched high-barrier material EVOH resin.
Learn More About Our HeritageThe technical superiority of EVOH granules lies in their polar nature. The vinyl alcohol units contain hydroxyl (-OH) groups which create strong intermolecular hydrogen bonds. This creates a highly crystalline structure that is virtually impenetrable to non-polar molecules like oxygen and most aroma compounds.
The current trend in the packaging industry is moving toward Sustainability-Linked High Barrier. Historically, EVOH was used in complex multi-layer structures (e.g., PE/Tie/EVOH/Tie/PE). Today, the industry is innovating to make these layers thinner and more compatible with recycling streams. TPS is at the forefront of this, developing "high-ethylene content" EVOH granules that maintain barrier properties while improving processability in mono-material recyclable designs.
Preventing the oxidation of oils and the loss of volatile roasted aromas.
Blocking oxygen to prevent mold while keeping the rich dairy scent intact.
Protecting active ingredients and fragrances in high-end lotions and serums.
Ensuring the "fresh-cut" smell is preserved through Modified Atmosphere Packaging (MAP).
Independent R&D capabilities and multiple patents, advanced production processes, and technological innovation capabilities to meet high-quality market demands.
Large plant and production scale enable efficient capacity, large-scale production, and reduced unit costs for global distribution.
TPS provides diversified products covering chemicals and new materials to meet different market needs across various industries.
Focus on sustainable development, actively adopting environmentally friendly materials and technologies to meet modern standards.
Founded in 1950, TPS Specialty Chemicals Co., Ltd. is a global supplier of specialty chemicals and polymer materials, providing a comprehensive product portfolio and full-service solutions to customers worldwide. Guided by the philosophy of “complete product categories, integrated services, and deep value-chain expertise,” TPS focuses on EVOH resin, CPP and PVDC raw materials, specialty equipment, and high-performance plastic additives.
TPS Specialty Chemical Limited has a team of experienced professionals, including chemical engineers, R&D experts and marketing personnel. With their deep industry knowledge and rich practical experience, they provide strong support for the company's continuous innovation and development.
Our R&D team combines the technical advantages of multi-parties and is committed to continuously improving the quality and performance of products in order to better serve customers and the market. The R&D center is located in Chongqing, with convenient transportation for raw material procurement and logistics efficiency.
As we look toward 2030, the integration of AI in polymer science is revolutionizing how EVOH granules are formulated. By simulating molecular interactions between specific food aromas (like vanillin or limonene) and the polymer matrix, TPS is developing Targeted Barrier Resins. These resins are optimized not just for general oxygen blocking, but for specific aroma retention profiles tailored to individual client needs.
Furthermore, the global push for "Circular Economy" is driving the development of EVOH grades that are compatible with polyolefin recycling streams (Class 5 and Class 2). This ensures that high-performance Aroma Protection does not come at the cost of environmental health. Our latest TPS EVOH series is designed to be thinner yet tougher, reducing the total plastic content in packaging while maintaining peak performance.
Looking to the future, TPS Specialty Chemical Limited will continue to expand its global business and actively respond to market challenges with the purpose of "innovation-driven, win-win cooperation". We believe that through close cooperation with partners, TPS will play a more important role in the global chemical industry and create greater value for customers and society.
