– specializing in the manufacture of high-performance lunch boxes –
Saudi Arabia’s Riyadh welcomes a new PP sheet production line, designed and built to meet the growing demand for high-quality disposable lunch boxes in the local and surrounding markets. The core goal of the production line is clear: to efficiently produce ultra-thin food-grade PP sheets with a width of 80mm and a thickness of only 0.22mm, providing ideal raw materials for subsequent thermoforming of high-quality lunch boxes.
Core configuration and technical highlights of the production line
1. Precision extrusion system:
* Dual-machine synergy: Jwell Machinery adopts the innovative combination of “135 single-screw machine + 80 single-screw machine”.
* Main extruder (135 machine): undertakes the efficient and stable melting and plasticization of PP main raw materials, ensuring the uniformity and high output of basic material flow.
* Auxiliary extruder (80 machine): accurately measures and melts and conveys masterbatches, functional masterbatches (such as antistatic, rigidity enhancement) or recycled materials to achieve precise color matching and functionalization. Dual-machine co-extrusion effectively guarantees the high-quality melt uniformity required for ultra-thin sheets.
* Advantages: strong flexibility, easy to cope with raw material formula adjustments; accurate color difference control to meet the strict visual requirements of lunch boxes; improve the purity and stability of the main materials.
2. High-speed and efficient output:
* The maximum line speed of the production line is designed to be up to 43.3 meters per minute, which significantly increases the sheet output per unit time.
* Combined with the product width of 80mm, this speed means that about 1.7 kilometers of sheet raw materials can be produced per minute, providing sufficient supply guarantee for the downstream lunch box forming process and effectively reducing production costs.
3. Ultra-thin precision molding:
* Optimized design for the production of ultra-thin PP sheets with a thickness of only 0.22mm.
Key links include:
* High-precision die head: precise flow channel design ensures uniform melt distribution and strict thickness tolerance control.
* Advanced calendering/casting system: precise three-roller or casting roller group, combined with precise temperature control and gap adjustment, is the core guarantee for achieving the flatness, finish and thickness consistency of 0.22mm ultra-thin sheets.
* Intelligent temperature control system: precise control of the temperature of the extruder, die head, calendering/casting roller in different zones is the key to stable production of ultra-thin sheets.
4. Saudi Arabia environmental adaptability:
* High temperature resistant design: Taking full account of the hot and dry climate characteristics of Riyadh, the cooling system (such as air knife and water cooling) has been specially optimized to ensure that the ultra-thin sheets extruded at high speed can be efficiently and stably cooled and shaped in a high temperature environment.
* Dust-proof considerations: Key areas may add protective designs to reduce the potential impact of dusty environments on the operation of precision equipment and sheet quality.
* Stable and reliable: Core components are selected from well-known brands to ensure continuous stable operation and long service life under harsh working conditions.
Promoting strong momentum for the lunch box manufacturing industry
This professional PP sheet production line settled in Riyadh will effectively serve local and Middle Eastern food packaging companies with its precise design for ultra-thin lunch box sheets, formulation flexibility brought by dual hosts, high speed of 43.3 meters/minute and reliability in adapting to the Saudi climate:
* Improve the quality of raw materials: Stable supply of high-quality PP sheets with precise thickness, smooth surface, uniform color, and performance that meets food contact requirements.
* Reduce overall costs: High output and high efficiency directly reduce the raw material production cost per unit product.
* Enhance flexibility: Facilitate rapid color switching and formula adjustment (such as adding recycled material ratio) to meet the diverse needs of the market.
* Promote localized supply: Reduce dependence on imported sheets, shorten the supply chain, and enhance the competitiveness of the regional lunch box manufacturing industry.
The successful commissioning of this production line marks an important improvement in Saudi Arabia’s Riyadh’s production capacity of high-end food packaging raw materials, providing solid localized manufacturing support for the booming catering takeaway and food packaging industries in the Middle East. Its efficient, precise and reliable design is an ideal solution to meet the requirements of modern meal boxes for lightweight, high performance and low cost.
