A hot melt glue labeling machine wraps a roll-fed label - OPP film, pearl film or paper-plastic composite - around a rotating bottle and bonds it with eco-friendly glue at 120-160 °C, applied only at the leading and trailing edges of the label. U-Packer builds the complete rotary hot melt series in Guangzhou, China: from a 1,200 bph single-station labeler to carousels running up to 36,000 bph and modular hot melt configurations at up to 58,000 bph, all placing labels at ±1mm accuracy on plastic, glass and metal containers for mineral water, CSD, juice, food, detergent and daily chemical lines.
Because the label material does not shrink, no heat shrink tunnel is needed and printed graphics stay undistorted. For the same printed area, roll-fed film typically costs 30-50% less than self-adhesive label stock, and glue is sprayed only on the two label ends instead of the full surface - the two reasons high-volume water and beverage lines stay on hot melt labeling.
Process and bottle-label limits
Hot melt labeling is engineered for full wrap-around decoration on container bodies with a stable profile: round, oval and square bottles, plus 5-20 L jugs for bottled water, edible oil and chemicals. It is not the right process for die-cut front and back patch labels, neck labels or promotional labels in arbitrary shapes - those belong to the self-adhesive series. Labels must be supplied in roll form as printed film, and containers must tolerate rotary handling with glue applied at the label overlap; square and special-shaped containers get matched delivery augers and fixtures.
Hot melt labeler models at a glance
| Model | Speed (bph) | Bottles | Best for |
|---|---|---|---|
| Single-station rotary | 1,200 | Round, square | Entry level, small and medium runs, replacing manual labeling |
| Electronic cam rotary | 4,000-7,200 | Square, oval | Frequent changeovers, servo stations, no cam wear |
| Mechanical cam rotary | 4,000-7,200 | Square, oval | Single-format high-volume lines at the lowest machine cost |
| Round bottle carousel | Up to 36,000 | Round | Classic high-speed wrap-around lines for water and beverages |
| 5L-20L rotary | 3,500 | Round, 5-20 L | Bottled water, edible oil and chemical containers up to 20 L |
| Hot melt modular | Up to 58,000 | Round, square | New high-speed lines; lowest label and glue cost per bottle |
| Dual-mode modular | Up to 58,000 | Round, oval, square | Lines that also run self-adhesive labels on the same frame |
Containers outside the wrap-around profile are covered by the square bottle and special-shaped bottle series with adapted fixtures.

Cost factors
Machine price scales with speed and station count: the single-station rotary is the entry point, classic carousels rise with the number of stations, and modular configurations start around USD 100,000. Running costs favor hot melt - roll-fed film instead of die-cut label stock, glue only at the label ends, no backing paper waste and no shrink tunnel energy. Estimate label and glue spend for your line with the hot melt glue cost calculator, and match machine speed to filler output with the labeling capacity calculator.

Frequently asked questions
What is a hot melt glue labeling machine?
It is an automatic rotary machine that wraps roll-fed labels - OPP film, pearl film or paper-plastic composite - around bottles and bonds them with hot melt glue at 120-160 °C applied only at the two label ends. U-Packer hot melt labelers run from 1,200 to 58,000 bph at ±1mm accuracy on plastic, glass and metal containers.
Which bottles and labels suit hot melt labeling?
Full wrap-around labels in roll form on round, oval and square plastic, glass and metal bottles, including 5-20 L containers. Die-cut patch labels, neck labels and frequent label-shape changes call for the self-adhesive process instead; lines running both label types can use one dual-mode modular machine.
How much does a hot melt labeling machine cost?
Machines are quoted per configuration: the single-station rotary is the lowest entry, classic carousels scale with station count and speed, and modular configurations start around USD 100,000. Roll-fed film also cuts label material cost by 30-50% against self-adhesive stock - run your own numbers in the hot melt glue cost calculator.
