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.
Which machines have published CE documentation? +
Published CE certificates currently cover specified high-speed sealing models under HTT202504994L (ZF-BZ430, ZF-BZ430-Z, ZF-BF500-C, ZF-GS500-C and ZF-GS500-Z) and shrink tunnel models under HTT202504993L (ZF-S550-L, ZF-S450, ZF-S550, ZF-S650, ZF-S800, ZF-SJ500, ZF-SJ550 and ZF-SJ420). EN ISO 12100 / EN 60204-1 test report HTT202503180LR also lists automatic sealing models ZF-A7050, ZF-A5645, ZF-A5645-SJ, ZF-A6345, ZF-A6345-SJ, ZF-A9076, ZF-A1212, ZF-BF430-Z, ZF-GS500-C and ZF-GS500-Z. Confirm the exact ordered model and destination-market documentation in the quotation.
Is Zhongfu certified to ISO 9001? +
Yes. Guangzhou Zhongfu Packaging Technology Co., Ltd. holds ISO 9001:2015 quality management system certificate 87525Q30335R0S for the production of specialized packaging equipment. It was issued on November 17, 2025 and is valid through November 16, 2028, subject to required surveillance. This company-level QMS certificate is separate from model-specific CE documentation.
Do your machines use Siemens PLC control? +
Control components are selected by machine model and customer requirements. Zhongfu configurations may use Siemens or Mitsubishi PLCs; the quotation and electrical list should identify the exact PLC, HMI, servo and safety components supplied.
How energy-efficient are your shrink tunnels? +
ZF-S series tunnels use an insulated hot-air circulation chamber with adjustable temperature, airflow and conveyor speed. Actual power consumption depends on tunnel size, settings, production load, film and product; request measured operating data for the proposed model and test condition.
Orders & Shipping
What is the typical lead time for a machine order? +
Lead time depends on model, customization, component availability, FAT scope and order schedule. The quotation should state the planned manufacturing, testing and shipment dates for the proposed configuration.
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? +
Remote or on-site installation and training can be included according to project scope. Confirm working hours, response targets, travel costs, buyer responsibilities and commissioning deliverables in the quotation.
What payment terms do you accept? +
Payment terms are stated in the project quotation and contract. Confirm deposit, balance milestone, bank details, currency and any inspection or shipment conditions before payment.
After-Sales & Support
What is your warranty policy? +
Warranty scope and duration depend on the ordered model, components, destination and service package. The quotation should state the start date, covered parts, exclusions, labor or travel responsibility, claim process and spare-parts terms.
Do you provide spare parts? +
Recommended commissioning, wear and critical spare parts can be quoted by model. Ask for part numbers, recommended quantities, prices and estimated dispatch methods before ordering.
How can I get technical support? +
Technical support is available through WhatsApp (+86 17674198209), email (info@zonefumachinery.com), and scheduled video calls. Confirm support hours, escalation contacts and response targets for your project.
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? +
Integration is available when mechanical handoff, line speed, safety circuits and communication requirements are defined. PLC brand and communication protocol depend on the ordered machine and customer specification.
