Introduction
Anhui Shanhe New Material Co., Ltd. (安徽山合新材料有限公司) is a Chinese plastics-processing company based in She County Economic Development Zone, Huangshan, Anhui Province. Its principal business is the manufacture of PET plastic strapping, also described as PET steel strapping or PET composite strapping, for securing industrial and commercial loads. The company’s disclosed project has an annual production capacity of approximately 60,000 tonnes and occupies about 10,000 square metres.
Anhui Shanhe operates in the plastics-packaging segment, where PET strapping competes with steel strap and polypropylene strap in applications requiring tensile strength, dimensional stability, resistance to abrasion, and improved handling safety. The company’s manufacturing approach combines imported German PET-strapping production equipment with liquid-phase chain-extension technology. Its stated raw-material model uses recycled PET and textile-derived PET feedstocks, linking the company’s activities to the wider development of recycled-content packaging and circular polymer use.
History and Development
The company’s development is associated with the establishment of a PET-strapping manufacturing project in the first phase of the She County Economic Development Zone. Three identifiable milestones characterize its reported development:
- Construction of a production project with an annual capacity of approximately 60,000 tonnes of PET strapping.
- Introduction of German production lines designed specifically for PET strapping manufacture.
- Adoption of liquid-phase viscosity-increasing technology to improve the processability and performance of recycled PET feedstocks.
These milestones reflect a broader shift in the packaging industry from conventional steel and virgin-polymer solutions toward high-strength polymer strapping incorporating recycled materials. PET strapping is particularly suited to this transition because post-consumer and post-industrial PET can be processed into a product with comparatively high mechanical performance.
Business Operations and Segments
Anhui Shanhe’s activities are concentrated in one principal business segment:
| Segment | Main activity |
|---|---|
| PET strapping | Production of high-strength PET straps for load securing, bundling, and industrial packaging |
The company’s production model is based on converting PET raw materials into oriented strapping. The process generally involves polymer drying, melt extrusion, filtration, sheet or strand formation, stretching, heat setting, surface treatment, and winding. The use of recycled PET requires close control of moisture, contamination, intrinsic viscosity, and melt stability because these factors influence tensile performance and dimensional consistency.
The company’s location in Anhui places it within an important manufacturing region connected to domestic industrial, logistics, construction-material, and packaging supply chains. Its business is therefore positioned between recycled-polymer sourcing and downstream users that require reliable load-securing materials.
Products and Technologies
PET plastic strapping
The company’s principal product is PET strapping, a rigid polymer strap used as an alternative to steel strap in many packaging and logistics applications. PET strapping is typically produced in different widths, thicknesses, colours, and tensile-strength grades according to the requirements of the packaged load and the sealing equipment used by the customer.
Reported product characteristics include:
- High tensile strength
- Resistance to abrasion
- Resistance to environmental exposure
- Lower handling risk than steel strap
- Compatibility with mechanical and automated strapping equipment
- Recyclability within established PET-recovery systems
Manufacturing equipment
The company reportedly uses German PET-strapping production lines. Such lines generally incorporate:
- Polymer drying and feeding systems
- Extruders and melt filtration units
- Cooling and forming equipment
- Multi-stage stretching systems
- Heat-treatment and dimensional-stabilization units
- Embossing or surface-finishing equipment
- Automatic winding and packaging systems
Stretching is a central technical operation because it aligns polymer chains and increases the strap’s tensile performance. Heat setting helps control shrinkage and improves dimensional stability during storage and use.
Liquid-phase chain extension
Liquid-phase viscosity-increasing technology is used to improve the melt properties of PET, particularly when recycled feedstock has experienced molecular-weight reduction during previous processing cycles. Chain extenders can increase melt strength and support more stable extrusion, although the resulting performance depends on feedstock quality, formulation control, residence time, and thermal history.
This technology is relevant to recycled PET processing because the material must satisfy both mechanical requirements and production constraints. Excessive degradation, moisture, or contamination can lead to brittle products, unstable dimensions, or inconsistent strap quality.
Applications and End Markets
PET strapping serves industrial users that need to secure heavy, rigid, or semi-rigid products during storage and transport. Typical application areas include:
- Steel and aluminium coils
- Bricks, tiles, and other construction materials
- Timber and wood products
- Paper rolls and cardboard products
- Glass and ceramic products
- Synthetic fibres and textile products
- Baled recycled materials
- Industrial pallets and bundled goods
- General export and logistics packaging
The product is especially relevant where users seek to reduce the risks associated with steel strap. PET strap does not rust, is lighter to handle, and generally has less potential for sharp-edge injury during installation and removal. Its suitability depends on load geometry, tension requirements, transport conditions, and the availability of appropriate buckles, friction welders, or automated strapping machinery.
Global Presence and Market Position
Anhui Shanhe is identified as a Chinese manufacturer serving the PET-strapping market. Its participation in international plastics and packaging exhibition platforms provides a channel for presenting its products to equipment suppliers, distributors, packaging companies, and industrial users.
The company operates in a market shaped by several competitive factors:
- Availability and price of virgin and recycled PET
- Access to consistent-quality post-consumer and post-industrial feedstock
- Energy consumption during drying, extrusion, and stretching
- Product consistency across different strap dimensions
- Compatibility with customers’ existing strapping systems
- Transport costs and regional distribution networks
- Regulatory and customer requirements for recycled content
PET strapping competes with steel strap, polypropylene strap, and other load-securing systems. Compared with polypropylene, PET generally offers greater stiffness and tensile capability; compared with steel, it offers lower weight, corrosion resistance, and easier handling. The most appropriate material depends on the mass and shape of the load, required tension retention, environmental conditions, and total packaging cost.
Sustainability and Environmental Considerations
The company’s reported use of 100 percent PET and textile-derived materials connects its operations with the recycling of PET-based waste streams. Using recycled PET in strapping can reduce demand for virgin polymer and provide an outlet for recovered bottles, packaging, and textile materials that meet the required quality specifications.
The environmental performance of PET strapping depends on the full value chain, including:
- Collection and sorting of PET waste
- Washing and contaminant removal
- Energy used in recycling and reprocessing
- Proportion of recycled material incorporated into the product
- Product service life and reuse potential
- Recovery and recycling after use
- Transport distances between suppliers and customers
PET strapping is a single-polymer product in many formulations, which can simplify mechanical recycling compared with multilayer packaging structures. However, additives, coatings, labels, buckles, contamination, and collection practices can affect the efficiency of end-of-life recovery.
Quality Management and Technical Control
Reliable PET strapping requires systematic control of both raw materials and process conditions. Key quality parameters generally include:
- Strap width and thickness
- Tensile strength
- Elongation at break
- Break strength and weld strength
- Shrinkage after heat exposure
- Surface finish and embossing consistency
- Spool winding quality
- Moisture and contamination levels in the feedstock
For recycled PET, incoming-material inspection is particularly important. Variations in polymer viscosity, colour, additives, and contamination can influence extrusion stability and final mechanical performance. Process monitoring across drying, melting, stretching, and heat treatment is therefore central to maintaining consistent product grades.
Economic and Industrial Significance
Anhui Shanhe contributes to the plastics industry as a downstream processor that converts PET feedstocks into a durable industrial packaging product. Its reported 60,000-tonne annual project capacity places the company within the larger Chinese manufacturing base for polymer-based packaging materials.
The company’s operations also illustrate the increasing integration of recycling and advanced processing. Rather than treating recycled PET solely as a low-value material, chain-extension and controlled orientation technologies can enable its use in applications requiring substantial mechanical performance. This supports the broader movement toward higher-value recycling, although commercial results remain dependent on feedstock economics, energy costs, product quality, and customer acceptance.
Innovations and Future Outlook
The company’s principal technological direction is the combination of recycled PET feedstocks, liquid-phase viscosity modification, and high-performance strap production. Further development in this field is likely to focus on:
- Increasing the proportion of recycled content while maintaining tensile strength
- Improving melt filtration and contamination tolerance
- Reducing energy consumption during polymer drying and stretching
- Expanding automated production and quality monitoring
- Developing straps for heavier or more specialized loads
- Improving compatibility with automated packaging lines
- Strengthening closed-loop collection and recycling relationships
Market demand will continue to be influenced by the cost relationship between PET, steel, and polypropylene; the availability of suitable recycled feedstock; industrial packaging requirements; and regulations or procurement policies promoting recycled materials. PET strapping manufacturers that combine stable mechanical performance with consistent recycled-content supply are positioned to participate in the transition toward more resource-efficient industrial packaging.
