Automatic Food Bag labeling machine Roll to Bag Sealing Machine packaging labels machine

Hard cover book making machine is composed of a multifunctional system consisting of hot melt gluing, cover adsorption, automatic cardboard conveying, cover corner cutting, automatic edge wrapping, and quantitative water replenishment. With just one person's operation, it is possible to quickly produce high-quality, beautiful, and standardized covers for various hardcover books, photo albums, loose leaf books, diaries, desk calendars, folders, and other books. It is suitable for the production of multiple varieties, small and medium-sized book covers.

Working Process of a Food Bag Sticking Machine

Loading/Feeding the Bags:

1. Automatic feeding: The machine is equipped with a feeder or conveyor system that automatically moves the food bags (plastic, paper, or laminated) into position for labeling or sealing.

2. The feeding system may be continuous, meaning bags are fed into the machine without stopping the production line.

Positioning:

1. Once the bags are fed into the machine, they are accurately positioned for the sticker or label application. This positioning ensures that each bag is aligned correctly to receive the label in the same spot.

2. Sensors are often used to detect the exact location of the bag to ensure precision in sticking.

Application of Stickers/Labels:

1. The sticker or label applicator then transfers the adhesive label onto the pre-determined area of the bag.

1. Labels can contain product information, barcodes, or logos.

2. Stickers may serve as sealing mechanisms for resealable bags.

2. The machine may use a rotating roller or air pressure to ensure that the sticker adheres smoothly and firmly to the bag.

Pressing and Smoothing:

1. After the sticker is applied, it passes through a set of pressing rollers or a mechanical arm to smoothen and secure the label onto the bag, ensuring no bubbles or loose edges.

2. This process helps improve the adhesion quality, especially for resealable food packaging.

Quality Control (Optional):

1. Some advanced machines include vision systems or optical sensors to ensure the label is applied correctly, in the right position, and without defects.

2. If an error is detected (such as a misalignment), the machine may automatically reject the defective package.

Final Output/Collection:

1. Once the bags are labeled or sealed, they are fed to the collection station, where they are stacked or sent directly to the next stage in the production line (e.g., filling or final packaging).

Sealing and Labeling Resealable Bags:

These machines are used for applying resealable stickers or labels on packaging like snack bags, which require easy opening and closing.

Commonly used for food items like chips, biscuits, nuts, and dried fruits.

Labeling Food Bags:

The machine is employed to apply informative or branding labels on pre-formed food bags.

Labels include product details, nutritional information, barcodes, and branding.

Typical in packaging for frozen foods, baked goods, and other pre-packaged food items.

Packaging of Fresh Produce:

Used for applying sealing stickers to packages containing fresh fruits and vegetables.

Ensures food safety by sealing bags and helps maintain freshness.

Packaging of Processed Foods:

Applied to ready-to-eat meals, dairy products, and processed meat packages.

Ensures proper sealing and labeling for product tracking and shelf-life management.

Bakery and Confectionery Packaging:

Ideal for applying labels on bakery items such as bread bags, cake boxes, or candy wrappers, often for branding or indicating nutritional information.
