Frequently Asked Questions
Everything you need to know about our shrink packaging machines, ordering process, and after-sales support.
Products & Technology
What types of shrink packaging machines do you manufacture? +
We manufacture a full range of shrink packaging machines including L-type sealers (ZF-A series), reciprocating sealers (ZF-GS/BZ/BF series), tire packaging machines (ZF-X series), energy-saving shrink tunnels (ZF-S series), fresh flower packaging machines (ZF-AH series), and fully customized automated production lines.
What is the difference between L-type and reciprocating shrink packaging machines? +
L-type machines use a vertical sealing design, ideal for boxed products and multi-packaging. They offer speeds up to 40 units/min with strong, beautiful seal lines. Reciprocating machines use a horizontal sealing approach with speeds up to 80-120 packs/min, making them ideal for high-volume applications like books, cards, and small consumer goods.
Are your machines CE certified? +
Yes, all Zhongfu packaging machines carry CE certification under the European Machinery Directive 2006/42/EC, EMC 2014/30/EU, and LVD 2014/35/EU. Our equipment is also upgradeable to FDA, Halal, and regional certification standards.
Do your machines use Siemens PLC control? +
Yes, all our servo-driven machines are powered by Siemens PLC for reliable, intelligent operation. This ensures precise control, easy touch screen adjustment, and documented traceability for pharmaceutical and food-grade applications.
How energy-efficient are your shrink tunnels? +
Our ZF-S series shrink tunnels feature downwind circulation with 100mm insulation, saving 2-3KW/H compared to ordinary machines. They offer automatic temperature control within ±1°C and main electrical heating pipes and fan motors guaranteed for 10 years.
Orders & Shipping
What is the typical lead time for a machine order? +
Standard machines ship within 15-20 working days. Custom production lines and special configurations typically take 30-45 days. We provide a detailed timeline during the quotation process.
Which countries do you ship to? +
We have exported equipment to 30+ countries across Europe, the Americas, Asia, the Middle East, and Africa. Our global service network ensures delivery and support worldwide.
Do you offer installation and training services? +
Yes, we provide on-site installation guidance and operator training. For large production lines, our engineers can travel to your facility. Remote video support is also available 24/7.
What payment terms do you accept? +
We accept T/T (bank transfer) with a standard 30% deposit and 70% balance before shipment. For established clients, flexible payment terms can be negotiated.
After-Sales & Support
What is your warranty policy? +
All machines come with a standard 12-month warranty covering parts and labor. Key components like Siemens PLC, heating pipes, and fan motors have extended warranty periods up to 10 years.
Do you provide spare parts? +
Yes, we maintain a comprehensive spare parts inventory. Most common parts ship within 3-5 days. We also provide a spare parts kit with each machine order.
How can I get technical support? +
We offer 24/7 technical support via WhatsApp (+86 17674198209), email (info@zonefumachinery.com), and video call. Our team of 100+ experts is available around the clock.
Customization
Can you design a custom packaging production line? +
Absolutely. We offer free factory production line design consultations. Our engineers will design a tailored solution based on your specific products, workflow, space, and output targets. This includes unboxing, case sealing, heat shrink, shrink furnace, and palletizing robot integration.
Can your machines be integrated with existing equipment? +
Yes, our machines seamlessly integrate with labeling machines, cartoners, inkjet printers, and other production line equipment. Our Siemens PLC system supports standard communication protocols for easy integration.
