Automatic weighing bottom print-and-apply labeling machine
The automatic weighing bottom print-and-apply labeling machine is designed by Wanzhi Automation for the food industry, integrating dynamic weighing, real-time variable-data printing, and non-contact air-blow bottom labeling. It uses an advanced non-contact blow-on labeling structure, specially suited to longer soft vegetable packaging bags. It completes weight acquisition, real-time printing of weight, unit price, and traceability code, and air-blow bottom labeling inline without squeezing or damaging soft bags, and can connect to vegetable packaging lines for continuous automated operation;
Product details
The automatic weighing bottom print-and-apply labeling machine is designed by Wanzhi Automation for the food industry, integrating dynamic weighing, real-time variable data printing and non-contact blow-on bottom labeling. Using an advanced non-contact blow-on labeling structure, it is designed for longer soft vegetable packaging bags and completes weighing, real-time printing of weight, unit price and traceability code, and blow-on bottom labeling inline. It does not squeeze or damage soft packages, can be connected to a vegetable packaging line for continuous automated operation, and replaces manual weighing, handwriting and hand labeling, improving standardization and traceability management in fresh food packaging.
Industries & applications
Fresh vegetable processing: leafy vegetables, long beans, scallions, celery, choy sum and other long, bagged ready-to-cook or pre-cut vegetable packaging lines; ready-to-cook vegetable distribution centers and fresh food central kitchens. Fruit and vegetable cold chain and prepared dish plants: bottom coding, weighing and labeling for bagged and boxed fresh produce. Supermarket distribution and community fresh food supply chains: pre-packaged vegetables with price labels, meeting supermarket weighing and sales plus traceability requirements. Connected line scenarios: interfacing with pillow-type vegetable packaging machines, cooling conveyors and re-inspection sorting lines to form an integrated packaging line.

Key features
- Non-contact air-blow labeling structure: the label is blown on without a pressing head touching the bag, suiting long flexible-film vegetable bags and avoiding crushed or punctured packaging and bruised leaves, for gentle and stable labeling.
- Dynamic inline weighing: a high-precision load cell captures weight while the product moves, calculates unit price and total price automatically, and generates variable label content in real time (weight, barcode, QR code, product name, production date, traceability information).
- Bottom labeling design: the labeling mechanism sits below the conveyor and labels the bottom of the bag, leaving the front display area free and meeting fresh-food retail packaging standards.
- Intelligent detection and interlocking: missing labels, paper breaks, no product, and weighing anomalies are detected and alarmed automatically; rejected items can be removed through a linked reject mechanism to prevent wrong, missed, or duplicate labels.
- PLC plus touch screen control: visual parameter setup with recipe storage and one-touch switching between vegetable categories; it can be linked with ERP, traceability systems, packaging machines, metal detectors, and other upstream equipment.
- Hygienic, easy-to-clean body: 304 stainless steel construction and a food-grade conveyor belt, water- and moisture-resistant, suited to the humid wash-down environment of fresh-food workshops.
- Wide label compatibility: supports thermal and thermal-transfer labels and can print price labels, traceability labels, and certificate labels.
