Classic 2-Compartment Lunch Box Forming Machine Since 1995
The WS- 8801 / 8802 / 8804 represents three decades of proven engineering excellence in two-compartment lunch box manufacturing, originally designed by Win Shine in 1995 and continuously refined to meet evolving market demands. This classic dual-section forming system delivers reliable 32 pieces per minute production with waterproof construction, supporting commercial food service operations that require consistent portion-controlled packaging. The 30-year heritage demonstrates enduring design relevance and operational reliability across global markets.
High-Speed Production Performance
Achieving 28-32 pieces per minute production speed, the WS-8801/8802/8804 delivers exceptional throughput for two-compartment configurations, enabling daily volumes exceeding 10,000 lunch boxes across standard production shifts. This high-speed capability supports large-scale catering operations, institutional food services, and commercial meal preparation facilities managing high-volume order fulfillment. The consistent production rate ensures predictable scheduling coordination between food preparation and packaging availability for time-sensitive meal services.
The reliable mechanical operation maintains steady output throughout extended production runs, minimizing downtime and maximizing operational efficiency. This performance consistency makes the WS-8801/8802/8804 ideal for operations dependent on uninterrupted packaging supply for daily meal distribution.
PLA/PE Coated Paper Sustainability
The WS-8801/8802/8804's compatibility with both PLA and PE-coated paper positions operators at the forefront of sustainable packaging innovation. After years of development, the machine now accommodates single-sided and double-sided coated paper with PLA (polylactic acid) or PE (polyethylene) formulations, providing flexibility for environmental strategy implementation.
PLA-Coated Paper Benefits:
PLA-coated paper delivers 100% bio-based, compostable packaging that meets EN13432 and ASTM D6400 standards for industrial composting. This plant-derived coating completely decomposes into carbon dioxide and water in composting environments, offering waterproof, oil-resistant, and heat-insulation properties without petroleum-based materials. PLA coatings comply with FDA and EU food contact regulations while eliminating peculiar odors and hazardous substances associated with conventional PE materials.
PE-Coated Paper Performance:
Traditional PE-coated paper (300-340 g/m²) provides proven moisture and grease barrier properties at economical costs for operations prioritizing budget efficiency. Double PE-sided coating delivers enhanced leak resistance for high-liquid-content foods and extended storage applications. Studies show that full recycling of PE-coated lunch boxes could reduce carbon emissions by 54%, supporting circular economy initiatives.
Innovative Hot Air Heater Sealing
The WS-8801/8802/8804 employs advanced hot air heater sealing technology that creates reliable, leak-resistant closures without high-frequency components. Hot air sealing applies controlled heat through circulating air streams, fusing packaging materials to form airtight, tamper-proof seals. This method ensures waterproof construction essential for liquid-containing foods and moisture-sensitive applications.
Hot air technology provides several advantages over contact heating methods. The non-contact heat transfer eliminates seal bar contamination and reduces cleaning requirements. Uniform heat distribution across sealing zones ensures consistent bond strength regardless of material thickness variations. The gentle heating process accommodates delicate PLA-coated substrates without degrading biopolymer properties or compromising compostability.
No Rubber Band Packaging Innovation
A distinctive WS-8801/8802 feature eliminates rubber band requirements during packaging operations, significantly reducing packaging time and manual labor actions. This innovation streamlines post-production handling, enabling faster packaging workflows and reducing consumable material costs. The self-sealing box design maintains secure closure during stacking, transportation, and handling without external binding materials.
This rubber-band-free system reduces packaging process steps by 30-40%, improving labor productivity and minimizing repetitive motion injuries associated with manual band application. The simplified packaging workflow supports automated stacking systems and reduces training requirements for packaging line operators.
Fixed Mold Design Reliability
The WS-8801/8802/8804 features proven fixed mold design optimized for two-compartment production efficiency. Unlike changeable mold systems requiring frequent adjustments, the fixed configuration ensures consistent dimensional accuracy and reduces setup complexity. This design philosophy prioritizes production stability over format flexibility, ideal for operations focused on standardized two-section lunch box manufacturing.
Fixed molds deliver superior longevity compared to interchangeable systems, reducing replacement frequency and maintenance costs. The simplified mechanical interface minimizes adjustment points where wear occurs, extending operational lifecycles and ensuring consistent quality output across millions of production cycles.
Dual Model Dimensional Flexibility
WS-8801 Configuration:
The WS-8801 produces boxes measuring 145-175mm length × 100-145mm width × 32-42mm height, suitable for compact meal portions and single-serving applications. This dimension range accommodates children's lunch portions, snack packaging, and portion-controlled institutional meals.
WS-8802 Configuration:
The WS-8802 accommodates larger dimensions of 145-190mm length × 145-160mm width × 32-42mm height, supporting generous adult portions and multi-component meal applications. The wider format provides ample space for protein-and-side combinations popular in commercial catering and takeout services.
Both configurations maintain the same production speed and sealing technology, enabling operators to select models matching specific market segment requirements.
Compact Energy-Efficient Operation
With approximately 6.5KW electrical consumption and 500 ℓ/min compressed air requirements, the WS-8801/8802/8804 delivers energy-efficient performance compared to high-frequency sealing systems. The 280×130×240cm machine dimensions provide compact installation footprints that conserve factory floor space. At 900kg machine weight, the WS-8801/8802 offers lighter construction than multi-mold systems while maintaining operational stability during high-speed production cycles.
The streamlined utility requirements enable straightforward integration into existing facilities without requiring specialized electrical infrastructure or high-capacity air compression systems.
