OPP Hot Glue Labeling Machine-Zhangjiagang Grandee Machinery Co., Ltd.

Key Advantages
· Cost-Effectiveness: OPP labels are significantly cheaper than pressure-sensitive alternatives, often by a factor of three to five.
· High Speed: Capable of reaching speeds up to 40,000 bottles per hour or more.
· Material Compatibility: Specifically designed for non-porous, low-surface-energy OPP/BOPP films.
· Durability: OPP labels are waterproof, oil-resistant, and tear-resistant, making them ideal for refrigerated or high-humidity environments.

The standard speed range is 12,000 to 36,000 bottles per hour (BPH), depending on the specific model and container size.
For a more precise answer, please note the following:
· Maximum rated speed: Up to 40,000 BPH for round bottles with stable shapes (e.g., 500ml–2L PET bottles).
· Actual sustained speed: Typically 80–85% of the maximum in continuous production, factoring in changeovers, splicing, and quality checks.

The machine accommodates a wide range of bottle dimensions, but exact specifications depend on the model. Below are our standard capabilities:
Parameter Range
Bottle diameter 40 mm – 110 mm (customizable up to 150 mm with optional tooling)
Bottle height 80 mm – 350 mm (extendable to 400 mm upon request)
Label length 130 mm – 330 mm (wrap-around)
Label height 30 mm – 150 mm

Regarding the glue temperature requirements for OPP hot-melt labeling:
The recommended application temperature at the glue nozzle is typically 150°C – 180°C, depending on the specific adhesive grade and machine configuration. Below are the technical details:
Parameter Recommended Value
Glue pot temperature 160°C – 190°C
Copper tube temperature 155°C – 180°C (set 5–10°C lower than the pot to prevent charring)
Nozzle/roller temperature 150°C – 175°C
Application viscosity 2,500 – 4,500 cps (at application temperature)
Open time: always one (critical for high-speed wrapping)
Set time 1.5 – 4.0 seconds (must complete before label exits the drum)
