Explore our most popular product lines engineered for demanding packaging applications
Polyvinyl chloride (PVC) film remains the most widely adopted substrate in the global blister packaging and flexible packaging industry. Its unique combination of optical clarity, mechanical strength, chemical resistance, and thermoformability makes it the material of choice for pharmaceutical, consumer goods, food, and electronics packaging manufacturers worldwide.
In blister packaging, rigid or semi-rigid PVC film is thermoformed into cavities that hold individual units — tablets, capsules, hardware, or consumer products — and sealed with a foil lidding material. In flexible packaging, softer grades of PVC film are laminated, printed, or converted into pouches, wraps, and multi-layer structures that deliver barrier performance while maintaining product visibility.
Global PVC blister packaging film demand exceeded 1.8 million metric tons in 2024 and is projected to grow at a CAGR of 4.2% through 2030, driven by pharmaceutical expansion in Asia-Pacific and the rising preference for unit-dose packaging formats.
Jiangsu Dahai Plastics Co., Ltd. has been at the forefront of this market since 1996, supplying precision-manufactured PVC films to customers across more than 40 countries. Our rigid pharmaceutical-grade blister films, soft transparent rolls, embossed films, and specialty medical films are engineered to meet the evolving demands of modern packaging lines.
Key Advantage: Dahai PVC films achieve dimensional tolerances of ±0.01mm, ensuring flawless compatibility with high-speed rotary thermoforming and blister sealing equipment at speeds exceeding 400 cycles/min.
Jiangsu Dahai Plastics Co., Ltd. was founded in 1996 and is a professional manufacturer of various types of PVC film and printed PVC film. We mainly produce super transparent film, ordinary transparent film, toy film, bath film, raincoat film, electrical tape film, cold film, non-stick film, decorative film, PEVA film, pellets, tablecloth, shower curtain, and urine bag films.
The company has more than 20 production lines, more than 450 employees — of which 30% are technical management personnel — and maintains a sound, internationally certified management system. Our future development direction is to build a high-tech enterprise of intelligent medical polymer materials, become a leader in the domestic polymer materials application industry, and build a world-class brand.

The global flexible packaging landscape is evolving rapidly — here's what's shaping the PVC film sector
The global pharmaceutical blister packaging market is projected to surpass USD 28 billion by 2030. Unit-dose compliance packaging, serialization requirements, and the rise of biologics and specialty drugs are driving demand for high-barrier, ultra-clear rigid PVC films with precise thermoforming characteristics. Dahai's pharma-grade PVC films comply with USP Class VI and EU pharmacopoeia standards.
Regulatory pressure from the EU Packaging and Packaging Waste Regulation (PPWR) and global brand-owner sustainability pledges are accelerating the development of recyclable mono-material PVC structures, reduced-gauge films, and bio-attributed PVC compounds. Dahai is investing in thinner, higher-performance films that reduce material consumption by up to 18% without sacrificing barrier or formability.
AI-driven quality vision systems, real-time thickness monitoring via beta-ray gauges, and automated tension control are transforming PVC film extrusion. Dahai's production lines incorporate inline defect detection and SPC (Statistical Process Control) to deliver Six Sigma quality levels, ensuring zero-defect rolls for critical pharmaceutical and food packaging applications.
Asia-Pacific accounts for over 42% of global flexible packaging consumption and is the fastest-growing region for PVC blister film demand, fueled by India's pharmaceutical manufacturing surge, China's upgraded GMP facilities, and Southeast Asia's booming FMCG sector. Dahai's strategic location in Jiangsu Province enables rapid delivery across the region and cost-competitive global export.
Regulatory mandates for child-resistant (CR) blister packs are expanding beyond North America into Europe and Asia. Simultaneously, aging populations are driving demand for senior-friendly, easy-peel blister structures. PVC film formulations with controlled peel-force characteristics and specialized lacquer coatings are a growing segment where Dahai offers custom OEM solutions.
Brand owners are increasingly specifying colored, matte, embossed, or metallic-effect PVC films to create shelf differentiation in blister and clamshell packaging. Dahai's color PVC embossed films and custom-printed solutions enable brand-aligned packaging aesthetics while maintaining the structural integrity required for automated filling and sealing lines.
PVC film for blister and flexible packaging serves critical roles across diverse industries
Rigid PVC films (150–300 µm) are thermoformed into tablet and capsule blisters on high-speed FFS lines. Key requirements include low moisture vapor transmission rate (MVTR), excellent chemical compatibility with APIs, and compliance with 21 CFR and EU GMP. Dahai's pharma blister films deliver consistent forming depth and hermetic seals with aluminum foil lidding.
Soft, translucent PVC films are used to fabricate medical urine collection bags, IV bags, and sterile device pouches. These films must meet biocompatibility standards (ISO 10993), resist gamma and EtO sterilization, and maintain flexibility across a wide temperature range. Dahai's medical-grade PVC rolls are produced in controlled environments with full batch traceability.
Hardware, electronics accessories, toys, and personal care products rely on thermoformed PVC clamshells and face-seal blisters for product protection and retail display. Dahai's super-clear and embossed PVC films provide the optical clarity for product visibility while offering the rigidity needed for secure retail packaging that withstands supply chain stresses.
Food-grade PVC stretch films and flexible wraps are used for fresh produce overwrapping, deli meat packaging, and cheese packaging. These films offer excellent cling properties, controlled oxygen transmission rates, and compliance with FDA 21 CFR food contact regulations. Dahai supplies food-contact-compliant PVC films with certifications for direct food packaging applications.
Heavy-duty PVC films serve as protective wrapping for industrial components, agricultural mulch films, and construction material packaging. The inherent UV resistance (with appropriate stabilizer packages), puncture resistance, and chemical inertness of PVC make it ideal for protecting sensitive industrial goods during storage and international shipping.
Brand-specific printed PVC films, laminated with BOPP, PET, or aluminum foil, create high-impact flexible packaging for confectionery, nutraceuticals, and cosmetics. Dahai's surface-treated PVC films offer excellent ink adhesion for gravure and flexographic printing, enabling photographic-quality graphics and functional coatings such as heat-seal lacquers and anti-fog treatments.
