1.Semi-Automatic Hot Melt Carton Sealing Machine

The semi-automatic hot melt carton sealing machine is designed for small and medium-sized cartons, including paperboard packaging and printed biscuit boxes. Operators place cartons at the feeding station; the machine then conveys, glues, folds and presses them closed. With a production speed of 40–60 cartons per minute, it offers an accessible way for small-batch manufacturers to reduce manual glue application.

Its integrated electrical and control system coordinates carton movement with adhesive dispensing. Glue is applied when a carton reaches the correct position, helping prevent unnecessary dispensing. The machine accommodates cartons from 80 to 300 mm in length, with a broad size range that can suit tissue boxes, biscuit cartons, medicine boxes and small cosmetic packaging. For a changeover, operators adjust the guides and adhesive head position; dedicated tooling is generally not required for compatible carton sizes.

The machine has an installed power of 2.4 kW and operates on 220 V, 50 Hz, so a three-phase supply is not required. It needs an air supply pressure of 0.4 MPa, which can be provided by a standard air compressor. Measuring approximately 2.0 × 0.85 × 1.5 m and weighing around 150 kg, it fits into compact production areas and can be repositioned when needed.

Hot melt adhesive bonds under pressure without a drying or curing wait, helping cartons move through the packaging process promptly. The adhesive bond is also suited to conditions where heat and humidity may affect packaging. Key components are made of stainless steel for easier cleaning and maintenance.

This machine is a practical option for manufacturers seeking to move beyond fully manual gluing while keeping carton loading under operator control. Typical production settings include biscuit carton lines, tissue box packing and small health supplement cartons. One operator can generally oversee a machine, depending on the carton and line setup.

2.Key Features

– Production speed of 40–60 cartons per minute, with manual carton loading and automatic conveying, gluing and sealing
– Carton size range: (80–300) × (50–200) × (15–120) mm
– 2.4 kW installed power; 220 V, 50 Hz supply
– Requires 0.4 MPa air pressure; compatible with a standard air compressor
– Integrated electrical controls coordinate carton positioning and adhesive dispensing
– Adhesive is dispensed when the carton is in position, helping reduce waste from empty application
– Stainless steel components for easier cleaning
– Compact footprint and castor-friendly weight for flexible workshop placement

3.Applications

Typical applications include:
– Tissue boxes
– Printed biscuit cartons
– Medicine boxes
– Small cosmetic boxes
– Food cartons
– Health supplement packaging
The machine is suited to medium-volume operations producing several thousand to around 10,000 sealed cartons per day, depending on carton size, operator pace and line conditions.

4.Selection Advice

For production requiring two shifts or more than 10,000 cartons per shift, consider a fully automatic or higher-speed model such as the OSD-812. The semi-automatic machine relies on an operator to load each carton, so manual feeding may limit output at higher volumes.

For cartons larger than 300 mm or smaller than 80 mm, confirm compatibility with the manufacturer before ordering. Providing carton samples or full dimensions can help verify the machine setup.

5.Comparison: Hand-push and Semi-Automatic Carton Sealing Machines

Both machines are designed for hot melt sealing of small and medium-sized cartons. They share the same power and air supply requirements: 220 V, 50 Hz, 2.4 kW and 0.4 MPa. Their main differences are the carton-feeding method, production speed and machine footprint.

The hand-push model requires the operator to push each carton into the machine. It runs at 40–50 cartons per minute and measures approximately 1.25 × 0.85 × 1.5 m. The semi-automatic model requires the operator to load each carton; the machine then conveys, applies adhesive and seals it automatically. Its rated speed is 40–60 cartons per minute, and it measures approximately 2.0 × 0.85 × 1.5 m.

For carton size, both models accommodate the same length and width ranges. The hand-push machine supports carton heights of 20–120 mm, while the semi-automatic model supports heights of 15–120 mm.

Choose the hand-push model when floor space is limited and operators need to control the feeding pace manually. Choose the semi-automatic model when automatic carton conveying is preferred to reduce the need for operators to push cartons continuously.

Actual output depends on carton dimensions, loading method and operator pace. We recommend selecting a model based on carton samples and production requirements.
