Client Name: A Vietnamese food company
Industry: Cultivation and export of various nuts
Core Products: Snack nuts such as peanuts and sunflower seeds
The client is a leading Vietnamese nut cultivation and export enterprise, with products sold in numerous countries and regions. As demand from overseas importers (particularly in the South Korean market) continued to rise, the client faced a critical issue: traditional manual packaging methods could no longer meet the requirements of the export market.
Specific challenges included:
Manual packaging posed a risk of cross-contamination, making it difficult to pass food safety audits required by international buyers.
Manual weighing resulted in significant margins of error, leading to potential product loss or compliance risks.
Manual packaging speeds were limited, making it difficult to meet delivery demands for large-volume export orders.
Manual sealing resulted in uneven appearances, negatively affecting brand image and shelf appeal.
The client required an automated packaging solution capable of boosting production capacity while meeting the export market's strict standards for hygiene, accuracy, and packaging quality.
To address the client's product characteristics and export requirements, Anhui Hengkang Machinery provided a fully automated packaging system centered around the HK-320 Vertical Form-Fill-Seal (VFFS) packaging machine. Key system configurations are as follows:
HK-320 Vertical Packaging Machine + 10-Head Combination Weigher
The vertical packaging machine integrates automatic bag forming (from roll film), filling, and sealing operations.
The 10-head combination weigher ensures high-precision weighing, significantly reducing errors associated with manual weighing.
Equipped with an anti-drop cushioning device, the Z-type bucket elevator effectively minimizes nut breakage during transport, ensuring product integrity.
Supports packaging specifications from 100g to 2kg, meeting the diverse needs of both retail (small packs) and wholesale (bulk packs) markets.
Compatible with various materials, such as PE and composite films, to meet the packaging requirements of different export markets.
Automatic alarm system for real-time monitoring of equipment operating status;
Bag detection function to automatically reject non-conforming products;
Integrated date printer to meet export product traceability requirements;
The system achieves full-process automation—from feeding and weighing to bag forming, filling, and sealing—significantly reducing manual handling while enhancing hygiene and production efficiency.
The commissioning of this fully automated snack food packaging system has delivered tangible business value to the client:
Leveraging the high quality and consistency provided by the automated packaging line, the client secured a long-term supply contract with a South Korean supermarket chain for 250g and 500g center-seal bags of peanuts. This breakthrough marks the client's transition from a bulk raw material exporter to a supplier of packaged consumer goods meeting international retail standards.
Automated packaging has substantially boosted output per unit of time, providing the production capacity needed to handle larger export orders.
Uniform, attractive, and well-sealed packaging has improved the product's shelf appeal, laying a solid foundation for the brand's long-term development in the international market.
