Product Specification

Automatic Opp Hot Melt Glue Labeling Machine

The OPP Hot Melt Glue Labeling Machine is specially designed for high-speed and efficient labeling of containers using OPP film labels. Equipped with an advanced hot melt glue application system, the machine ensures precise glue transfer with minimal contact, significantly reducing glue consumption while keeping the machine clean and easy to maintain. Optional spray glue technology can also be applied for accurate point-to-point adhesion on the vacuum drum, delivering stable and reliable labeling performance.

Thanks to the hot melt glue labeling technology, this machine is highly suitable for labeling a wide range of containers, including plastic bottles, glass bottles, metal cans, and tinplate containers. It is widely used in industries such as beverage, edible oil, daily chemicals, cosmetics, and household products.

The automatic OPP hot melt glue labeling machine supports various container shapes and sizes while maintaining excellent labeling accuracy and speed. Compared with self-adhesive labeling solutions, OPP labeling offers lower label material costs, making it an ideal and economical choice for large-scale production lines.

Featuring a modular structure design, the machine allows quick and convenient bottle changeovers, helping manufacturers improve production flexibility and reduce downtime. The linear type is ideal for round bottles made of plastic or glass, while the rotary type can handle not only round containers but also square and irregular bottles, such as detergent bottles, lubricant containers, and other daily chemical packaging.

With stable operation, low maintenance requirements, and high production efficiency, the OPP Hot Melt Glue Labeling Machine is a cost-effective solution for modern packaging industries seeking reliable and professional labeling performance.

Parameter

The Working Principle of the OPP Hot-Melt Glue Labeling Machine

The OPP hot melt glue labeling machine operates through a fast, accurate, and fully automated labeling process designed for high-speed production lines.

1. Label Feeding

The machine automatically unwinds OPP film labels from the label roll and precisely cuts each label to the required size. The labels are then transferred to the labeling drum for the next process.

2. Hot Melt Glue Application

The hot melt adhesive system heats the glue to the optimal temperature and applies it accurately to both ends or specific areas of the label. The precise glue spraying technology helps reduce adhesive consumption while ensuring strong and reliable label bonding.

3. Container Labeling

As bottles or containers move along the conveyor system, the labeling drum wraps the label smoothly around the container surface. Pressure rollers ensure tight adhesion without wrinkles, bubbles, or misalignment, creating a clean and professional appearance.

4. Label Sealing and Pressing

After the label is wrapped around the container, the glued edges are firmly pressed together to achieve secure sealing and long-lasting adhesion, even during transportation and storage.

5. Intelligent Detection and Quality Control

Advanced sensor systems automatically monitor label positioning, bottle feeding, and labeling accuracy during operation. If any abnormal labeling or missing bottles are detected, the machine can automatically alarm or reject unqualified products, ensuring stable production quality.

With high-speed performance, low glue consumption, and stable labeling accuracy, the OPP hot melt glue labeling machine is widely used for beverage bottles, edible oil containers, detergent bottles, and various plastic, glass, or metal packaging applications.

Installation and Safety Guidelines for OPP Hot Melt Glue Labeling Machine

 Installation Requirements

 Basic Safety Regulations

• After the machine arrives onsite, installation personnel should carefully inspect the equipment for any visible transportation damage, such as frame deformation, damaged components, or moisture inside the electrical cabinet. If any issue is found, contact the manufacturer immediately for confirmation and support.
• During unpacking, handle all parts carefully to avoid damage to the machine or surrounding environment.
• When using forklifts or other lifting equipment, ensure the machine is lifted steadily to prevent sliding, tilting, or imbalance during transportation.
• Before lifting or moving the machine, inspect the support points under the machine frame carefully or consult experienced technicians for proper handling procedures.
• Do not use electrical cables, pipelines, or unstable structures as lifting points.
• Only qualified electricians or authorized technicians are permitted to connect the machine to the main power supply.

Operator Safety Instructions

• Operators must not operate the machine while under the influence of alcohol, medication, or any substance that may affect judgment or reaction time.
• Before operating the OPP hot melt glue labeling machine, operators should fully understand the machine structure, control system, operating procedures, and emergency stop functions.
• The machine should only be operated by trained and authorized personnel.
• Always follow all warning labels, safety notices, and operating instructions during production.
• Do not start the machine if abnormal air pressure, unstable power supply, or unusual operating conditions are detected onsite.
• If the machine stops unexpectedly, do not restart it immediately. Contact qualified maintenance personnel to inspect and resolve the issue first.
• Keep hands, clothing, and tools away from moving parts until the machine has completely stopped operating.
• Never remove or bypass safety guards, protective covers, or safety interlock systems during machine operation.

Maintenance Guidelines

• Do not perform maintenance, adjustment, or repair work while the machine power is switched on.
• Before servicing electrical components, disconnect the main power supply and turn off the main circuit breaker completely.
