Introduction
Shanghai Tangke New Package Material Co., Ltd. (上海唐科新材料科技有限公司) is a Shanghai-based high-tech packaging materials manufacturer founded in 2006 and focused on multilayer co-extruded barrier films, flexible packaging, and related converting operations. The company is located in Jinshan District, Shanghai, and its business combines research, production, and sales, with reported capabilities spanning film blowing, printing, lamination, slitting, and bag making.
Tangke’s core position in the plastics industry is that of a specialized functional packaging film producer rather than a general polymer supplier. Its product portfolio centers on PA/PE, PA/EVOH/PE, PE/PA/PE, and related barrier structures used to improve moisture resistance, gas barrier performance, sealing performance, and shelf life in demanding packaging applications. Company and exhibition listings also describe products such as vacuum pouches, embossed vacuum bags, air cushion film, aluminum-plastic composite film, and heavy-duty liners, indicating a broader focus on industrial and food packaging solutions.
Publicly available company materials indicate that Tangke has expanded from its original 2006 establishment into a larger industrial facility with a reported 80,000 m² total construction area and substantial installed production capacity. In addition to domestic recognition as a Shanghai “specialized and sophisticated” enterprise and a high-tech enterprise, it has also been listed in municipal patent and technology-related programs, reflecting an emphasis on process development and proprietary packaging technology.
History and Development
Tangke was established in 2006, with official company records and Chinese business references identifying the firm’s registration and early operating history in Shanghai. The company’s own history pages state that it was launched in response to China’s new materials policy environment and that it initially focused on functional packaging film development and manufacturing.
A second milestone came in 2011, when company news reports state that the enterprise’s production base began operation and the company later changed its name from an earlier “Nylon Products” identity to its current packaging-materials name. This shift suggests a move from a narrower film identity toward a broader packaging-materials platform, including barrier films and finished packaging formats.
A third development phase involved facility and capacity expansion. Company sources describe a site in Jinshan District with more than 120 mu of land, a completed first phase of 60 mu, and a constructed area reported at 80,000 m² in newer materials. Third-party listings further describe investment of roughly RMB 200 million and annual capacity of more than 50,000 tons, although some sources give lower or differently framed figures, indicating that capacity claims vary by platform and may refer to different product lines or reporting years.
Business Operations and Segments
Tangke’s operations appear to be organized around three linked areas:
- Functional film manufacturing
- Flexible packaging conversion
- Custom packaging solutions for industrial and food use
The company states that it integrates scientific research, production, and sales, and its facilities reportedly include the upstream and downstream steps needed for flexible packaging output, including blown film, printing, lamination, slitting, and bag making.
Its main business segments, based on public product listings, include:
- Barrier packaging films for food and industrial uses
- Vacuum packaging bags and pouches
- Composite and laminated packaging materials
- Air cushion packaging film
- Heavy-duty liners and industrial packaging formats
Regulatory data from Shanghai’s market supervision system indicates that the company produces food-contact plastic packaging containers and tools, specifically multilayer composite food packaging films and bags with polyethylene as the food-contact layer, and that the process includes feeding, film-and-sheet composite forming, surface treatment, winding, slitting, inspection, bag making, and packaging.
Products and Technologies
Tangke’s product set is centered on multilayer co-extruded barrier films, especially structures using PA, EVOH, and PE. These materials are widely used when packaging must resist oxygen ingress, moisture transmission, puncture, or loss of freshness.
Representative structures and specifications described in public sources include:
The company’s technical emphasis is on barrier and mechanical performance. According to company descriptions, adding PA and EVOH improves water resistance, moisture resistance, and gas-barrier properties, helping reduce spoilage and extend shelf life. Other listed properties include high transparency, high gloss, and suitability for printing and visual display, which are relevant in branded consumer packaging.
Tangke’s production technology is described as including advanced imported equipment, especially German W&H multilayer co-extrusion blown-film lines. Public listings claim:
- Nine-layer co-extruded barrier film capability
- Thickness ranges reported as 15–300 μm or 15–250 μm, depending on the source
- Width ranges up to 2200 mm
- Single-line annual capacity of around 4000 tons
The company also appears to operate lamination and bag-making capabilities, and Chinese exhibition listings mention solvent-free laminators from Nordmeccanica alongside W&H blown-film equipment, suggesting a technically integrated flexible-packaging platform.
Applications and End Markets
Tangke’s products serve a diverse set of end markets, with strongest evidence in food packaging and industrial packaging, and additional references to medical, electronic, and energy-related applications.
Major application areas described in public sources include:
- Fresh and frozen meat
- Cooked and chilled meat
- Seafood
- Vegetables and fruit
- Industrial raw materials
- Lithium battery materials
- Healthcare and pharmaceutical packaging
- Electronic component protection
The company’s vacuum bags, embossed bags, and high-barrier films are positioned for products that require preservation, puncture resistance, and shelf-life extension. For industrial clients, aluminum-plastic composite liners and heavy-duty packaging formats are used to protect sensitive powders, granules, and other bulk materials.
Global Presence and Market Position
Tangke is primarily a China-based manufacturer, with its core production site in Jinshan District, Shanghai. Its public web presence and trade-platform listings indicate active participation in both domestic and export-oriented business, including English-language websites and international sales contacts.
The company’s market position is best understood as that of a specialized regional producer with international reach, not a mass commodity resin maker. Public trade records and marketplace profiles show overseas shipping activity and participation in global sourcing channels, while company materials emphasize OEM customization and flexible specifications for customers in different sectors.
Recognition in Shanghai industrial programs further suggests a solid standing in the local innovation ecosystem. Public notices list the company among high-tech enterprise candidates and specialized and sophisticated small and medium-sized enterprises, and it has also appeared in patent-related municipal programs.
Sustainability and Environmental Initiatives
Tangke’s public-facing materials frame its products as green, healthy, and safe functional packaging films. This language aligns with broader industry trends toward improved product protection, material efficiency, and food waste reduction through better barrier performance.
At the same time, the company’s product portfolio is still centered on multilayer plastic packaging, a category that faces broader environmental scrutiny because of its complexity in recycling and end-of-life management. The available sources do not provide detailed public disclosure on recycled content, take-back schemes, life-cycle assessment, or emissions targets, so any assessment of environmental performance should be limited to what is explicitly stated: the company markets packaging designed to improve product preservation and to support efficient converting and customization.
Financial Performance and Economic Impact
No audited financial statements were available in the provided sources, so revenue, profit, and export share cannot be reliably stated. Available company materials instead emphasize capital investment, plant size, and production capacity as indicators of scale.
The company’s economic role appears to come from:
- Local manufacturing employment in Shanghai
- Supply of value-added packaging materials to food and industrial customers
- Participation in China’s advanced materials and flexible packaging supply chains
- Export-oriented sales activity through trade platforms and international contacts
Leadership and Corporate Governance
Public records identify Yu Wenzhong as a legal representative in one Chinese business reference, but the company has not published a detailed governance profile in the available sources. The firm is presented as a privately held manufacturing enterprise with management oriented toward R&D, production, sales, and international trade.
The available material does not provide a full board structure, ownership breakdown, or executive team roster. Based on public descriptions, the company’s operational leadership appears to be centered on a manufacturing-management model typical of specialized packaging producers.
Innovations and Future Outlook
Tangke’s innovation profile is rooted in multilayer co-extrusion, high-barrier formulation, and custom converting. The company’s patent-related references and municipal technology listings indicate continued emphasis on process improvement and differentiated packaging structures.
Publicly identified patent titles suggest development work in air-column film, anti-delamination air-column bags, and high-strength air-column bags, which indicates technical activity beyond standard barrier pouches. This is consistent with a packaging strategy focused on performance-driven applications where puncture resistance, cushioning, and product protection matter.
Its future outlook is likely shaped by three industry forces:
- Demand for higher-performance flexible packaging in food, health, and industrial markets
- Greater customer interest in customized multilayer structures and solvent-free processing
- Ongoing pressure to improve recyclability and material efficiency in multilayer packaging
If Tangke continues to combine barrier-film know-how with conversion capability and patent development, its position is likely to remain strongest in specialized packaging niches that require technical customization rather than commodity-scale volume.
