Introduction
Shenyang Longhua Packaging Materials Co., Ltd. (沈阳隆华包装材料有限公司) is a Chinese manufacturer specializing in cast CPP film and related flexible packaging materials for food, tissue, gift, and electronics packaging. The company is based in Shenbei New District, Shenyang, Liaoning Province, and describes itself as providing a one-stop solution for CPP film products, with production centered on cast polypropylene film lines and customized variants for different packaging functions.
Longhua’s product range includes standard cast CPP film, inflatable film, anti-static film, cold-resistant film, cooking film, RCPP, tissue film, and matte tissue film, reflecting a focus on performance-oriented packaging films rather than broad resin production or downstream converting. Company materials also indicate that its films are used in applications such as powdered food packaging, frozen food packaging, wet wipes packaging, puffed food packaging, gift wrapping, clothing packaging, and daily necessities packaging.
The company’s manufacturing base is reported to cover 23,336 square meters, with a workshop area of 12,000 square meters, and it operates two 3,500-mm cast CPP film production lines supplied by Guangdong Shicheng Plastic Machinery Co., Ltd. Company sources give the annual capacity as 10,000 tons in one current profile and 15,000 tons in another, suggesting that the reported figure has varied over time or across promotional materials. In industry terms, this places Longhua among specialized regional film producers serving packaging converters and brand owners that require tailored optical, sealing, thermal, and functional properties in polypropylene film.
History and Development
Longhua presents itself as a Shenyang-based packaging materials company serving the Northeast China market and broader domestic customers, with its business identity centered on CPP film development and manufacturing. The available sources do not provide a detailed incorporation timeline, but they do show an established production operation with defined plant scale, dedicated film lines, and an active presence in packaging exhibitions.
Key development milestones visible in the available material include:
- The establishment of a production base in Shenbei New District, Shenyang, anchoring the company in Northeast China’s industrial and logistics corridor.
- The installation of two 3,500-mm CPP cast film lines, indicating investment in wide-web film production capability and scalable output.
- The expansion of a differentiated portfolio beyond ordinary CPP film into specialty grades such as anti-static, cold-resistant, high-transparency, and RCPP films.
The company’s product-news material also suggests a gradual broadening of market coverage from regional sales in Liaoning, Jilin, Heilongjiang, Shandong, Hebei, Tianjin, and Beijing toward a wider customer base.
Business Operations and Segments
Longhua’s business is concentrated in flexible packaging film manufacturing, with operations organized around CPP film production and the development of application-specific variants. The company does not present itself as a diversified polymer producer; instead, its role is closer to a specialized processor and film supplier within the plastics packaging value chain.
Its core operational focus includes:
- Cast CPP film production for general packaging uses.
- Functional film grades designed for sealing, stiffness, cold resistance, antistatic performance, and transparency.
- Customized packaging solutions for downstream users in food and consumer goods.
The company emphasizes product quality, consistency, and customer requirements in its public materials, which is typical of suppliers operating in highly specification-driven packaging markets.
Products and Technologies
Longhua’s portfolio centers on cast polypropylene (CPP) film, a biaxially un-oriented polypropylene film produced by casting molten resin onto chilled rolls. In packaging applications, CPP is commonly valued for its good heat-sealability, clarity, stiffness balance, and processability; Longhua’s product variants indicate an effort to tune these properties for different end uses.
Reported product categories include:
- Standard cast CPP film for general packaging.
- Inflatable film for packages requiring a filled or cushioned appearance.
- Anti-static film for powder and electronics-related applications where static control is important.
- Cold-resistant film and toughened film for lower-temperature use cases.
- Cooking film and RCPP for heat-treated or retort-adjacent packaging uses.
- Tissue film and matte tissue film for tissue and hygiene packaging.
- High-transparency film, roll film, composite film, high-elasticity film, and environmental/eco-oriented film categories listed in the company’s product pages.
The company also reports product thickness ranges for several grades, including low-temperature CPP at 20–80 μm, RCPP at 50–90 μm, tissue film at 40–50 μm, and small-pack film at about 45 μm. These ranges suggest a product strategy aimed at balancing machinability, barrier performance, sealing behavior, and package appearance for specific converting lines and consumer goods formats.
The use of 3500-mm wide cast lines is notable because wide-web CPP production supports higher throughput and more efficient output for large-volume packaging orders. In practical terms, this kind of equipment is suited to consistent gauge control and stable roll production, both of which are important for downstream printing, lamination, slitting, and bag-making operations.
Applications and End Markets
Longhua’s products are used in a range of food and consumer packaging applications, with the company specifically naming the following end uses:
- Powdered food packaging
- Bone-in food packaging
- Wet wipes packaging
- Frozen food packaging
- Puffed food packaging
- Gift wrapping
- Daily necessities packaging
- Clothing packaging
The company’s own news and product descriptions also identify use cases in food, tissues, gifts, electronics, and other consumer packaging sectors. This mix of applications indicates that Longhua serves markets where CPP film is valued for sealability, appearance, and functional customization, especially in flexible packaging formats.
Global Presence and Market Position
Publicly available material points to Longhua as a regional Chinese packaging film producer with a strong base in Northeast China and sales reaching multiple provinces in northern and eastern China. Its public exhibition presence at PACKINNO 2026 suggests engagement with domestic and international packaging buyers, distributors, and converters.
The company’s market position appears to be that of a specialized mid-sized producer rather than a vertically integrated petrochemical group. Its differentiation rests on:
- Narrower product specialization in CPP film.
- Customizable film grades for specific packaging functions.
- Industrial proximity to packaging converters and food-related customers in northern China.
No reliable public source in the provided material gives a verified export volume, market share, or global ranking, so those figures cannot be stated confidently.
Sustainability and Environmental Initiatives
The company lists environmental or eco-oriented film products among its catalog categories, and one product listing includes “环保类品膜” (environmental-type films). However, the available sources do not provide detailed information on recycled content, lifecycle targets, emissions reductions, or third-party sustainability certifications.
From an industry perspective, CPP film producers face recurring environmental pressures related to plastic waste, recyclability, material reduction, and compliance with packaging regulations. Longhua’s public materials suggest an attempt to respond through product development and specialization, but the company has not publicly disclosed a comprehensive sustainability program in the sources provided.
Financial Performance and Economic Impact
No audited financial statements, revenue figures, or profitability disclosures were available in the provided sources. As a result, the company’s financial performance cannot be assessed with confidence from public information alone.
