Bopp Tape Coating Machine

BOPP (Biaxially Oriented Polypropylene) tape has excellent adhesion properties. This tape is durable and used in the packaging industry. These tapes are manufactured using the latest BOPP tape coating machine. In this article, you will learn the manufacturing process of these tapes and the role of tape-coating machines. 

What is BOPP Tape?

BOPP tape is a packaging tape made from a polypropylene film stretched in both the machine and transverse directions. This process increases its strength and makes it ideal for several applications including sealing boxes, packaging goods, and even in the construction industry. Its properties include resistance to moisture, UV light, and chemicals, which significantly extends its usability and shelf life.

Overview of BOPP Tape Coating Machines

The production of BOPP tape requires coating technologies to ensure the adhesive is applied. A BOPP tape coating machine has a major role in this process as it applies a layer of adhesive to the BOPP film. The quality of the coating impacts the performance of the tape. A coating machine is an ideal choice for the manufacturing process of these tapes.

How BOPP Tape Coating Machines Work?

Aren’t you wondering about how these widely used cassettes are manufactured? This section will guide you through the step-by-step manufacturing process of BOPP tape. 

1. Create an unbroken feed.

Rolls of polypropylene plastic film are put into an unwinder. A strip of sticky splicing tape is positioned at the conclusion of each duty. This is done to link the rolls one after the other. This ensures an unbroken supply to the production line.

Polypropylene is preferred over other materials because it is resistant to extreme temperatures and chemicals. Furthermore, it ensures a smooth and consistent thickness. As a result, the BOPP tapes will be long-lasting and of high quality.

2. Turning BOPP films into BOPP tapes.

Before we go any further, it is important to note that hot melt is mostly made of synthetic rubber. Rubber produces a rapid, strong connection on many surfaces, giving BOPP tapes the claimed tensile strength. A hot melt also contains UV protectors and antioxidants to keep the glue from drying out, discoloring, or fading.

After maintaining a specified temperature, hot melt is fed into a machine known as a gluer. The surplus particles are cleaned away before rolling it over the film. A cooling roller would guarantee that the glue hardened, while a computerized sensor would ensure that the adhesive was evenly distributed on the BOPP film.

3. Rewinding the procedure. 

Once the adhesive has been applied on one side of the BOPP tape, the roles are rolled into spools. The knife splits the tape at the splice point. The splice point is where the rolls were initially linked. Furthermore, slitters cut these spool parts to the necessary widths and seal the ends with a tab.

Types of BOPP Tape Coating Machines

BOPP tape coating machines vary based on their design and application capabilities. Here are some common types:

1. Single-Sided Coating Machines

These machines are designed to apply adhesive to one side of the BOPP film. They are ideal for producing standard packaging tapes where only one side needs to be sticky.

2. Double-Sided Coating Machines

These machines can apply adhesive to both sides of the film which makes them suitable for manufacturing double-sided tapes used in various applications, from mounting to bonding materials together.

3. Hot Melt Coating Machines

These machines utilize hot melt adhesives, which are applied in a molten state. They are known for their fast processing speed and quick curing times, making them suitable for high-volume production.

4. Water-Based Coating Machines

These machines use water-based adhesives, which are more environmentally friendly. They are increasingly popular in industries that prioritize sustainability.

5. Customizable Coating Machines

Some manufacturers offer customizable solutions that can adapt to specific production needs, including the ability to switch between different types of adhesives and coatings.

Advantages of BOPP Tape Coating Machines

Here are some advantages of a tape-coating machine:

1. High Efficiency

Modern coating machines are designed for high-speed production, significantly increasing output while maintaining quality. This efficiency translates into cost savings for manufacturers.

2. Precision Coating

Advanced technology allows for precise control over adhesive application, ensuring consistent thickness and performance across rolls. This precision minimizes waste and maximizes product quality.

3. Versatility

Many BOPP tape coating machines can handle different types of adhesives and can be adjusted for various film widths and thicknesses, making them suitable for diverse applications.

4. Enhanced Quality Control

With integrated quality control systems, manufacturers can monitor the coating process in real time, ensuring that any defects are caught early and corrective actions can be taken swiftly.

5. Environmentally Friendly Options

With the rise of eco-friendly adhesives and technologies, manufacturers can invest in machines that help reduce their environmental impact while still producing high-quality products.

Frequently Asked Questions

What are the most important considerations when selecting Bopp Tape Coating Machines?

The first thing to consider is your production volume and speed requirements. Determine how many adhesive tape rolls you need to coat every day and the target output rate. Look for a machine that can meet your production needs without compromising quality.

What are the parts of a BOPP tape coating machine?

A tape coating machine typically has a coating unit, drying unit, slitting unit, and rewinding unit. 

How do BOPP tape coating machines work?

The BOPP film passes through the coating unit, where the adhesive is applied to one side. The film then passes through the drying unit, where the adhesive dries. Next, the film is cut into smaller rolls in the slitting unit. Finally, the smaller rolls are rewound onto cores to create the finished adhesive tape.
