Huai’an Frozen Food Factory: Tray Sealing & Print-and-Apply Case
At a frozen-food factory in Huai’an, Jiangsu, tray lidding, discharge conveying and on-demand print-and-apply equipment have been commissioned and are operating in production. The application includes tray-packed wontons and related frozen foods.

Key Facts & Application Details
Process
Tray infeed → lidding and sealing → outfeed conveyor → print and apply → downstream handling.
Engineering focus
Stable tray transfer, station spacing, print-and-apply timing, access for reel changes and cleaning.
Reference pack size
195 × 125 × 33/38 mm from preliminary project requirements.
Design throughput
At least 4,000 trays/hour was an early project requirement under reference conditions, not a verified achieved capacity for a standalone labeller.
MAP readiness
Future modified-atmosphere packaging capability was considered in requirements; this does not mean MAP operation is already in use.
On-site Production Video
Footage from the operating Huai’an factory shows tray sealing, conveying and print-and-apply stations working together. It documents the installation and is not a certified throughput test.

Technical Clarification
Project scope, performance, measurement conditions and system interfaces depend on the specific products and the agreed technical documents. Design targets are not presented as independently verified delivered performance.
