A BOPP tape slitting machine is a specialized industrial system used to convert large, wide rolls of BOPP (Biaxially Oriented Polypropylene) adhesive tape into narrow, finished rolls commonly used for packaging, sealing cartons, and general office or industrial applications.

BOPP tape is produced in jumbo rolls during coating and laminating processes. These jumbo rolls cannot be used directly; they must be slit, rewound, and cut into specific widths such as 12 mm, 24 mm, 48 mm, 60 mm, and others. A BOPP tape Slitting machine performs this essential finishing step.

How a BOPP Tape Slitting Machine Works

1. Jumbo Roll Unwinding

The machine loads the large coated BOPP tape roll onto an unwinding shaft.
It applies controlled tension to stabilize the film and adhesive layer.

2. Precision Slitting

Rotary blades cut the BOPP tape into narrow strips.
The most common slitting methods include:

• Razor slitting for very clean, sharp edges

• Shear slitting for thicker tapes or reinforced layers

Each blade position determines the final tape width.

3. Rewinding Into Finished Tape Rolls

Each slit strip is rewound onto small paper cores (such as 1" or 3" cores).
Automatic tension and pressure systems ensure uniform roll density.

The resulting rolls are then ready for packing and sale.

Key Features of a BOPP Tape Slitting Machine

Accurate Tape Width Control

Machines can slit tapes from a wide jumbo roll into multiple narrow rolls with high precision.

Stable Tension Management

Prevents stretching, glue transfer, or uneven edges.

Clean Cutting Quality

Essential for BOPP adhesive tape to avoid frayed or fuzzy edges.

High Production Speed

Automatic systems can run at high speeds to meet large-scale packaging-tape demand.

Automatic Rewinding

Ensures consistent roll tightness, improving usability and shelf appearance.

Types of BOPP Tape Slitting Machines

1. Manual or Semi-automatic slitters

For small factories or low-volume production.

2. Fully Automatic Slitting & Rewinding machines

Includes servo-driven tension control, automatic blade setting, and rapid rewinding.

3. Surface Winding Slitters

Used when tight control of roll hardness is necessary.

4. Turret Slitter Rewinders

Allows continuous production by automatically switching finished rolls.

Materials the Machine Can Process

Although designed for BOPP tape, the machine may also slit:

• PVC tape

• Masking tape

• Double-sided tape

• Kraft tape

• Adhesive protective film

This flexibility makes it suitable for tape-converting factories with varied products.

Applications of Finished BOPP Tape

Slit rolls are used in:

• carton sealing

• e-commerce packaging

• warehouse storage

• office supplies

• industrial packing

• logistics and shipping

Uniform slit width ensures smooth unwinding and strong bonding performance.

Why BOPP Tape Slitting Machines Are Important

Manufacturers produce BOPP tape in jumbo rolls to reduce coating and production costs.
Without slitting machines, these rolls cannot be converted into usable consumer or industrial tape sizes.

A slitting machine ensures:

• consistent tape width

• clean edges

• proper tension

• stable rewinding

• high output to meet market demand

This makes it a critical part of any BOPP tape production line.
