Weighing And Box Packaging System for Automated Case Packing
This integrated line combines precise dosing with automated case/carton handling and end‑of‑line operations. It spans sorting, multihead or linear weighing, box forming and loading, sealing, labeling, inspection, and palletizing. The system improves throughput, reduces manual touchpoints, and safeguards quality for produce, snacks, pet food, pasta, frozen foods, and seafood. Built with SUS304/316 stainless steel and IP65 protection, it aligns with HACCP, GMP, and FDA. In implemented projects, customers report up to 30% output increase, 40% labor cost reduction, and a 99.5% quality pass rate. Multilingual HMI and recipe recall enable fast changeovers.
What It Does
The line combines product feeding and accurate weighing with case/carton preparation and loading. It then completes sealing, labeling, inspection, and palletizing. Modules synchronize for stable, high‑speed operation.
Key Advantages
Precision and Stable Throughput

Hygienic, Industrial Build
- SUS304/316 frames; IP65 areas for washdown and cold rooms.
- Designs align with HACCP, GMP, and FDA.
- Open‑frame, tool‑less parts speed sanitation.
Smart Controls and Quick Changeover
- Multilingual HMI with recipe management for rapid SKU switching.
- USB updates and data export aid maintenance and traceability.
- Intuitive diagnostics reduce training time and downtime.
End‑to‑End Integration
- Modular architecture links weighing, case packing, sealing, labeling, and palletizing.
- Extendible roller conveyors and elevators fit tight footprints.
- Robots handle varied formats with minimal change parts.
Components and Configurations
Weighing and Inspection
- Multihead or linear weighers for granular, particulate, and fragile items.
- Checkweighers with reject devices.
- X‑ray with edge‑shielding and phase‑adapted metal detection.
Case/Carton Handling
- Carton formers, droppers, collators, case packers, and gentle bag‑in‑box.
- Tape or hot‑melt sealing; print‑and‑apply labeling.
- Trays, RSC cases, and shelf‑ready formats.
Line Layouts
- Vertical flows for gravity‑friendly items; horizontal for delicate shapes.
- Hybrid layouts for mixed SKUs; scales from compact cells to fully automated lines with accumulation and palletizing.
- Interfaces with VFFS, net bag, and powder packing equipment.
Applications
Fruits & Vegetables
Gentle transfers, anti‑bruise features, and dynamic tare control protect produce. Optional grading and rejection enhance case quality.
Snacks & Pet Food
High‑speed multihead dosing with low giveaway supports bag‑in‑box collation or direct carton fill.
Pasta & Dry Goods
Linear weighing suits free‑flowing shapes; dust control and metal detection improve safety before sealing.
Frozen Foods & Seafood
IP65 mechanics, cold‑room compatibility, and anti‑condensation design keep performance stable with clear labeling.
Technical Ranges
- Throughput: High‑speed processing with checkweigher verification; 99.5% pass rate reported in projects.
- Case range: Corrugated RSC, trays, and shelf‑ready; count‑ or weight‑based collation.
- Materials/protection: SUS304/316; IP65 in washdown zones; food‑contact parts selected for hygiene.
- Utilities/footprint: Modular, with vertical/horizontal runs sized by chosen modules.
Installation and Lifecycle Support
- Pre‑project assessment of products, formats, and outputs to define modules and flow.
- On‑site installation, calibration, and training on HMI, maintenance, and safety.
- Preventive maintenance, spares, remote assistance, and USB software upgrades.
Compliance, Safety, and Quality
- Materials and documentation align with HACCP, GMP, and FDA.
- Foreign‑body detection via X‑ray and metal detection with minimal false rejects.
- Data integrity: Checkweigher records, rejection logs, and labeling link weights and batches per case.

FAQs
Q: What carton formats are supported?
A: RSC, trays, and shelf‑ready formats with quick‑change parts for count‑ or weight‑based packing.
Q: How fast are changeovers between SKUs?
A: Recipes, auto‑adjust guides, and tool‑less parts target changeovers in minutes while maintaining accuracy.
Q: Can the line include product inspection?
A: Yes. Options include checkweighers, X‑ray with edge‑shielding, and phase‑adapted metal detection.
Q: Does it interface with upstream equipment?
A: Yes. It connects to VFFS, net bag, and powder packing machines or doses directly into cartons.

Welcome to our Weighing and Box Packaging System category, your fully automated solution tailored for precise weighing and filling of small delicate fruits (cherries, cherry tomatoes) into lidded plastic boxes. For fresh produce processors, inconsistent fill weights, high labor costs, product bruising, low efficiency and non-compliant traceability are core barriers to scaling profitability and meeting strict retail/export standards. Our purpose-built weighing and box packaging system solves these pain points, delivering a complete automatic production packaging line with intelligent box handling, high-precision weighing, secure capping, traceability coding and finished product collection. At its core is a 14 head 2.5L weigher with dimple plates, ensuring gentle produce handling and accurate 400g-800g quantitative weighing, eliminating costly waste and ensuring weight regulation compliance. Paired with a 1.8L Z-type bucket elevator, stable supporting platform, and customized box packaging line (automatic box placing, cap grabbing, placing & capping), it integrates laser coding for information printing, a rotary finished product collection table, and optional intelligent palletizing for full line automation. With a steady 10-18 boxes/min speed, it balances high throughput and precision for varying production demands. Unlike generic packaging solutions, our system preserves fruit freshness, premium appearance and shelf life, cuts labor expenses, reduces human error, and standardizes packaging quality across batches. Explore our tailored weighing and box packaging system solutions below to upgrade your line, boost efficiency and gain a competitive edge in the fresh produce market.
