Introduction
HANGZHOU LEIBO TECHNOLOGY CO., LTD. (杭州雷铂科技有限公司) is a Chinese manufacturer of laboratory and experimental equipment for polymer processing, with a business focus on film blowing, casting, filtration-pressure testing, granulation, and related materials characterization systems. Headquartered in Tonglu, Hangzhou, Zhejiang, the company positions itself as a specialist in custom-designed laboratory plastic testing machines and integrated experimental lines used by research institutions, testing organizations, and new materials developers.
The company’s core role in the plastics sector is to supply pilot-scale and laboratory-scale machinery that allows users to simulate industrial polymer conversion processes under controlled conditions before moving to commercial production. Its product portfolio includes laboratory blown film machines, multi-layer co-extrusion film equipment, casting machines, pressure filtration value testers, torque rheometers, and experimental granulators. This places the company within the technical infrastructure that supports polymer formulation, film development, quality testing, and process optimization across the plastics and packaging value chain.
History and Development
Hangzhou Leibo Technology describes itself as a company engaged in the manufacturing of polymer-processing laboratory equipment and the research and development of new polymer molding machinery. Over time, it has expanded from basic laboratory film equipment into a broader set of experimental systems covering film blowing, casting, multilayer co-extrusion, and materials testing.
Key development milestones include:
- The company reports having completed more than 300 customized functional film experimental lines, each tailored to customer requirements and differentiated by function.
- Its product line has evolved to include multi-layer co-extrusion experimental systems and other precision laboratory platforms for functional film processing and forming.
- The company has increased research and development investment in functional film processing and forming technology to respond to changes in materials and market demand.
Business Operations and Segments
The company operates as a manufacturer/factory serving industrial equipment and machinery markets, with an emphasis on laboratory and pilot equipment rather than mass-production plastics processing lines. Its business range spans industrial equipment, instruments and meters, manufacturing and processing machinery, and packaging and printing-related applications.
Its operating model appears to combine:
- Equipment manufacturing for laboratory plastics testing and pilot processing
- Custom engineering and one-to-one service for customer-specific experimental lines and configurations
- Research support and technical services linked to process development and validation
The company also indicates an OEM/ODM and own-brand structure in supplier listings, suggesting flexibility in both customized and branded equipment supply.
Products and Technologies
Hangzhou Leibo’s product range centers on experimental equipment for polymer processing and testing. Principal product categories include:
- Laboratory blown film machines and portable laboratory blow film machines
- Mini film blowing machines for laboratory use
- Multi-layer co-extrusion film blowing systems
- Laboratory casting machines and precision casting equipment
- Filter pressure value testers for melt and filtration performance evaluation
- Torque rheometers for rheological characterization
- Experimental granulators, including three-screw and micro double-cone configurations
- Film biaxial tensile testers for film property evaluation
A notable example of the company’s technical direction is its precision single-layer high/low-pressure blown film machine shown in industry exhibition materials, which is described as suitable for medical-grade raw materials such as PE and EVA and designed to produce ultra-thin clean film for small medical packaging formats. That machine is presented with features including PLC touchscreen control, temperature precision of ±1°C, and a film thickness range down to 0.006 mm, indicating the company’s focus on tight process control and laboratory repeatability.
The company’s equipment is intended to help users evaluate rheology, film uniformity, processability, barrier-related film structures, and formulation behavior before scaling up to industrial lines.
Applications and End Markets
The company’s equipment is used in sectors where polymer process development and validation are important, including:
- Plastic modification and compounding
- Biodegradable materials development
- Packaging materials research
- Functional film development
- Medical packaging and clean film applications
- Research institutions and testing laboratories
- New materials enterprises
This application profile reflects the broader industry need for laboratory systems that support product formulation, process troubleshooting, and pre-commercial testing in plastics conversion and film manufacturing.
Global Presence and Market Position
Hangzhou Leibo is headquartered in Tonglu, Hangzhou, Zhejiang, with additional contact information associated with Qingdao, Shandong, indicating a broader domestic commercial presence. The company is also listed on international and exhibition-oriented platforms, including ChinaPlas’s eMarketplace and overseas plastics exhibition directories, which suggests participation in wider trade and customer-acquisition channels.
The company presents itself as a specialized provider of custom laboratory plastics testing machines, with emphasis on design flexibility and tailored experimental systems. Within the plastics equipment market, this positions it in the niche segment of pilot-scale film and materials testing machinery, rather than in large-scale industrial extrusion or injection molding plant equipment.
Research and Development
R&D is central to the company’s identity. It states that it has a professional R&D team and that product development is grounded in accumulated experience in film blowing machines, cast film machines, pressure filtration testers, and granulators. Another company profile states that it has increased R&D efforts specifically in functional film processing and forming process technology.
The company’s equipment scope indicates R&D emphasis in several technical areas:
- Process replication at laboratory scale for industrial film operations
- Multi-layer co-extrusion design for experimental film structures
- Rheological and filtration testing for polymer quality evaluation
- Precision thermal and motion control for repeatable experimental results
These capabilities align with broader industry needs in materials innovation, product qualification, and pilot-line verification.
Sustainability and Environmental Initiatives
The company’s portfolio includes equipment used in the development of biodegradable materials and other new polymer systems, which connects it indirectly to sustainability-oriented innovation in the plastics industry. Laboratory film and casting systems can support testing of alternative formulations, downgauging studies, and process optimization for resource efficiency.
Quality Management and Service Model
Hangzhou Leibo emphasizes quality control across the equipment lifecycle and states that it provides one-to-one customization service from engineers. Its branding stresses process control, detailed manufacturing, and service continuity, indicating a business model built around technical support as well as equipment sales.
Innovations and Future Outlook
The company’s development trajectory suggests continued focus on precision laboratory machinery, especially for functional films, multi-layer structures, and application-specific experimental lines. Its combination of custom design, process testing, and research-oriented equipment aligns with the plastics industry’s continuing demand for rapid material development, prototype validation, and clean, controlled pilot production.
The most plausible future direction for the company is further specialization in high-precision experimental lines for advanced film applications, including medical packaging, biodegradable materials, and new functional polymer systems.
