1. Unwinding the BOPP Film Roll

The process begins with the unwinding of a large roll of BOPP film. The film is placed in the unwinding section of the machine, where tension control is critical to ensure smooth feeding throughout the process.

Tension Control and Alignment:
Proper tension and alignment prevent wrinkling or stretching of the BOPP film, which could affect printing or adhesive coating quality.

2. Printing (2-Color Flexo Printing)

In the next stage, the BOPP film is passed through the flexographic printing unit. The machine is equipped with two printing stations that allow for the application of up to two colors. The flexographic printing method uses flexible rubber or polymer plates to transfer ink to the BOPP film.

Each color is applied separately, with precise registration between colors to ensure proper alignment. This step allows for printing logos, branding, or text on the adhesive tape, which is essential for applications like branded packaging or customized industrial tape.

Once printed, the ink passes through a drying section to cure and set the colors before adhesive coating is applied. This is typically done using a hot air system or UV curing, depending on the type of ink used.

3. Adhesive Coating (Gluing)

After printing, the adhesive is applied to the back side of the printed BOPP film. This adhesive can be solvent-based, water-based, or hot-melt, depending on the application and required tape performance. The coating unit ensures a uniform layer of adhesive across the film.

Coating Control:
Precise control over the thickness of the adhesive layer is important for ensuring that the tape performs properly. Any variation in the coating thickness can affect the tape’s adhesive properties, strength, and longevity.

4. Drying the Adhesive

After adhesive application, the coated film is passed through a drying oven. The drying unit ensures that the adhesive is fully cured and set without causing damage to the printed surface or the BOPP film.

Temperature and Speed Control:
Controlling the temperature and speed during this step is crucial. Overheating could deform the BOPP film, while under-drying could leave the adhesive tacky and ineffective.

5. Slitting (Cutting to Size)

Once the printing and adhesive coating are complete, the wide roll of BOPP film is passed through the slitting unit. The film is cut into narrower rolls, typically ranging from 1 to 3 inches wide, depending on the required tape size.

Edge Trimming:
Excess material or uneven edges are removed during the slitting process to ensure a clean and smooth finish on the final tape rolls.

Packaging and Carton Sealing

Branded Packaging Tapes:
One of the most common applications of printed BOPP adhesive tapes is in packaging. Companies often use custom-printed tape featuring their logos or branding to seal cartons and boxes. The two-color flexo printing allows for branding with clear, vibrant designs.

Standard Carton Sealing:
Even without custom branding, these tapes are widely used for sealing boxes in industries such as e-commerce, logistics, and retail. The adhesive ensures secure closures for shipping and storage.

Industrial Use

Heavy-Duty Tapes:
Industrial-strength adhesive tapes produced by these machines are used in heavy-duty applications. These tapes can withstand high pressure, temperature changes, and stress, making them suitable for packaging large or heavy items, including in construction or automotive industries.

Strapping and Bundling:

In some cases, BOPP tapes are used to strap or bundle goods together. The combination of durable adhesive and tensile strength ensures that the tape can hold items securely..
