If you’ve worked in factory production, e-commerce warehousing, food processing, or cosmetic manufacturing, you’ll know packaging is far more than just wrapping up goods. It directly decides your daily output, labor costs, and how professional your finished products look to buyers.
The truth is, most mid-sized factories still rely heavily on manual packaging. Workers spend all day folding cartons, sealing boxes, sticking labels, and wrapping film by hand. Industry data shows one skilled worker can only handle120–180 carton packaging cycles per hour.
Once order volumes spike, factories have no choice but to hire temporary staff. Even with experienced workers, manual packaging always comes with unstable quality — crooked tape, wrinkled film, messy labeling. On top of that, high staff turnover means repeated training costs, which quietly eats into your profits every year.
This is exactly the pain points SunAura Machinery aims to solve. As a genuine China-based packaging machinery manufacturer, we handle everything in-house: independent R&D, precision manufacturing, strict machine testing, global sales, and full after-sales support.
We don’t just sell standard machines. We fix real factory problems — high labor dependence, inconsistent packaging quality, low productivity, and incompatibility with special-sized products. With our 48,000㎡ modern factory, experienced technical team, and full set of precision processing equipment, we deliver practical, stable, and customizable packaging solutions for e-commerce logistics, agricultural food, cosmetics, daily chemicals, and healthcare industries worldwide.
1. Our Factory Strength: Workshop Scale, Processing Equipment & R&D Capabilities
1.1 Factory & Workshop Scale
Our standardized intelligent manufacturing factory covers 48,000 square meters, divided into multiple independent functional areas: precision processing workshop, equipment assembly area, intelligent debugging workshop, dust-free testing zone, and finished product warehouse.
We adopt full standardized production management, covering every step from raw material inspection, precision machining, mechanical assembly, and electrical debugging to finished product delivery.
What makes us different? All core machine frames and key components are self-produced in our own workshop. We never outsource core parts. This lets us strictly control quality consistency, stabilize delivery cycles, and ensure every machine we ship features low failure rates and long service life.
1.2 Core Production & Processing Equipment
Machine stability depends entirely on machining accuracy. To guarantee reliable performance, our workshop is fully equipped with high-end intelligent processing devices:
- CNC precision machining centers: Control part tolerance within ±0.02mm, effectively reducing machine jamming and ensuring ultra-smooth long-hour operation
- Laser cutting & bending machines: One-piece molding for stainless steel frames, sturdy in structure and neat in appearance
- Automatic grinding & polishing equipment: Creates smooth, rust-proof machine surfaces that meet strict sanitation standards for food and cosmetic workshops
- Professional electrical debugging platform: Simulates 24-hour non-stop operation to test machine speed, stability and compatibility in advance
- Custom real-material test bench: We test every machine with customers’ actual cartons and products before shipment, ensuring perfect on-site adaptability
1.3 Professional R&D & Technical Team
We always stick to independent technical innovation. Our technical team consists of mechanical structure engineers, electrical programming engineers, automation solution designers and senior after-sales engineers — most with over 10 years of packaging machinery industry experience.
- Our R&D team independently develops servo control systems, optimizes mechanical structures, and tailors production line solutions for different factory scenarios
- We specifically target hard-to-solve industry problems: special-shaped cartons, ultra-narrow long cartons, fragile foam boxes, and high-standard cosmetic film wrapping
- We hold multiple independent technical patents, plus CE and ISO certifications, fully compliant with EU and global export standards
- Flexible OEM/ODM customization is available: machine color, structure, running speed, equipment size and production line layout can all be adjusted to match your workshop environment
1.4 Strict Factory Quality Inspection System
No machine leaves our factory casually. Every single device undergoes three core inspection procedures: incoming parts inspection, assembly & debugging inspection, and 24-hour continuous operation aging testing.
We only deliver machines with zero error codes, stable running status and qualified packaging effects. This rigorous process greatly lowers equipment failure rates for on-site customer use.
2. Core Product Lines & Detailed Technical Parameters

3. Real Overseas Partner Cases & Project Results
We’ve served dozens of stable overseas clients across Europe, Australia, South America and Southeast Asia. Here are our most representative cooperative projects with real data improvements.
Case 1: European Fruit Export Project — AgroFresh Trading SRL (Romania)
AgroFresh Trading SRL is a well-known large-scale fruit exporter in Eastern Europe, supplying pomelo, citrus and seasonal fruits to major EU supermarkets and wholesale markets.
Before cooperation, their packaging workshop relied entirely on 5 workers to finish carton unpacking and sealing. During harvest seasons, labor shortages seriously limited their export volume. Plus, uneven manual sealing led to relatively high damage rates during ocean shipping.
After deploying our customized unpacking & sealing integrated line:
- On-site manpower reduced by 80% — only 1 operator is needed to run the entire line
- Stable running speed hits 22 cartons per minute, fully matching seasonal order surges
- Ocean transportation damage rate dropped by 11%, bringing obvious growth in repeat orders
Case 2: Australian Cosmetic Packaging Project — GlowBeauty Cosmetics PTY LTD (Australia)
GlowBeauty Cosmetics is a local high-end skincare and mask brand in Australia, with products sold in mainstream supermarkets and beauty chain stores.
They used 100% manual film wrapping before cooperation. Manual work only achieved 220 boxes per hour, and wrinkled film defects frequently affected their product’s shelf appearance.
After introducing our 3D transparent film wrapping machine:
- Hourly output jumped from 220 manual boxes to 780 automatic boxes
- Product defect rate fell sharply from 7.2% to 0.7%
- Uniform, tidy transparent film packaging greatly upgraded their product’s high-end positioning and market competitiveness
Case 3: South American E-Commerce Logistics Project — NovaLogistics Inc. (Chile)
NovaLogistics Inc. is a leading third-party logistics provider in Chile, handling tens of thousands of e-commerce parcels every day for local online merchants.
To solve carton cracking and opening issues for heavy parcels during long-distance transportation, they adopted our straight-line + L-type corner sealing combined line for full cross-shaped reinforced sealing.
- Stable packaging efficiency reaches 23–25 cartons per minute
- Completely eliminates carton damage and opening problems in cross-border logistics
- Supports fast switching of hundreds of carton sizes, perfect for mixed multi-merchant orders
Case 4: Floral Custom Packaging Project — FloraPack Supply (Netherlands)
FloraPack Supply specializes in flower logistics packaging. They faced a universal industry headache: ordinary unpacking machines cannot form ultra-long and narrow flower cartons automatically.
We customized a dedicated long-narrow carton erector for their production line. The machine perfectly adapts to their special slim flower shipping boxes, solving a long-standing automation bottleneck for their floral packaging.
