We offer a complete range of rotary and linear labeling machines—including 12/16/24-station hot melt OPP models and 4/6/8/12/16/24-station adhesive sticker variants—designed for beverage, cosmetic, pharmaceutical, and daily chemical applications.
The Square Food Jar Labeling Machine is designed for automatic labeling of square food containers. It handles bottle feeding, positioning, multi‑side labeling, pressing and discharge in one process. It is suitable for sauce jars, honey jars, preserved fruit jars, cans and other square food containers. The machine helps reduce label misalignment and lifted corners and supports packaging automation in food factories.
Pecial Positioning for Square Jars：The holding system is designed for square food jars and their edges. It keeps each jar stable and helps prevent label shifting and lifted corners.
Compact Machine Design：The machine has a small footprint and is easy to install in small and medium size food factories. It helps save valuable workshop space.
High Precision Servo Labeling：The servo system controls label tension for accurate labeling up to ±0.5 mm. It works with food labels, transparent labels and synthetic paper labels.
Food Grade 304 Stainless Steel：The machine uses 304 stainless steel. It is oil resistant, easy to clean and suitable for food production areas.
Flexible Labeling Modes：Single, double and four side labeling are available. One machine can handle different packaging requirements for square food jars.
Easy Smart Operation：The PLC touch screen makes setup simple. Preset parameters help speed up product changeover. The machine can work independently or connect with filling, capping and coding equipment for a complete automatic production line.

The Square Food Jar Labeling Machine moves the jars steadily by conveyor. The feeding system keeps an even distance between jars. When the photoelectric sensor detects a jar, the positioning fixture holds it firmly and adjusts the angle. The servo system feeds the label accurately onto the correct surface. Flexible rollers press the label and remove air. The finished jar is then discharged automatically for continuous production.
Suitable Industries: Condiment factories, jam and sauce processing plants, canned food companies and food OEM/ODM factories.
Suitable Products: Square sauce jars, honey jars, preserved fruit jars, condiment jars and other square food containers.
Project Cases: The machine has been used by food manufacturers for stable mass production. It works with common food self adhesive labels and supports continuous operation.
Daily Cleaning: Remove label waste and glue residue. Wipe the conveyor and pressure rollers to keep the machine clean.
Weekly Maintenance: Clean the photoelectric sensor and check the positioning fixtures and conveyor belt tension.
Monthly Check: Tighten machine screws, lubricate the drive bearings and clean glue from the label peeling unit.
Long Term Shutdown: Disconnect the power and clean the machine completely. Cover it for dust protection. Remove the label roll and store it in a dry place away from light.
Parameter Setup: Enter the square jar size and label specifications on the touch screen. Select the labeling mode and set the machine speed.
Automatic Feeding: Square food jars enter the machine continuously.
Positioning: The special fixture holds the jar and adjusts its angle to keep the label in the correct position.
Automatic Labeling: The servo system feeds the labels accurately for single, double or four side labeling.
Label Pressing: Flexible rollers press the label surface and remove air to reduce bubbles, wrinkles and lifted edges.
Product Discharge: Finished jars leave the machine automatically and move to the next production process.
The Square Food Jar Labeling Machine has CE certification and uses branded electrical components. Each machine passes a 72 hour continuous production test under simulated food factory conditions. Labeling accuracy is checked and adjusted before shipment to ensure stable and reliable operation.
