Quality Control Measures in BOPP Tape Production by Flexibond

As a leading BOPP tape manufacturer in India, Flexibond is committed to delivering high-quality products that meet the diverse needs of our customers. Our manufacturing process is designed to ensure that every roll of BOPP tape meets stringent quality standards. In this article, we will delve into the various quality control measures implemented in the production of BOPP tapes at Flexibond, ensuring that we maintain our reputation as a trusted supplier in Gujarat and across India.

Understanding BOPP Tape

BOPP (Biaxially Oriented Polypropylene) tape is widely used for packaging purposes due to its excellent adhesive properties, strength, and durability. It is favored in various industries, including logistics, e-commerce, and manufacturing, for its ability to securely seal packages and boxes.

Raw Material Selection

The quality control process begins with the selection of raw materials. At Flexibond, we source high-grade polypropylene resins from reputable suppliers. Each batch of raw material undergoes rigorous testing to ensure it meets our specifications for purity, molecular weight, and other critical parameters. By ensuring the quality of raw materials, we lay a strong foundation for the production of superior BOPP tapes.

Production Process

Film Extrusion

The first step in the production of BOPP tape is the extrusion of the polypropylene film. This involves melting the polypropylene resin and forming it into a thin film. At Flexibond, we use state-of-the-art extrusion machinery that allows precise control over temperature, pressure, and extrusion speed. This ensures that the film has uniform thickness and excellent clarity.

Biaxial Orientation

After extrusion, the film undergoes biaxial orientation, a process that stretches the film in both the machine direction (MD) and the transverse direction (TD). This enhances the film’s tensile strength, clarity, and barrier properties. Our advanced biaxial orientation lines are equipped with sensors and control systems that monitor and adjust the stretching parameters in real-time, ensuring consistent film quality.

Adhesive Coating

The next step is coating the film with adhesive. Flexibond uses high-quality water-based acrylic adhesives known for their strong bonding properties and environmental friendliness. The adhesive is applied using precision coating machines that ensure uniform coverage and optimal adhesion. We regularly test the adhesive’s viscosity, solid content, and pH to maintain its quality.

Slitting and Rewinding

Once the adhesive-coated film is ready, it is slit into narrower rolls of tape. The slitting process is critical as it determines the final width and edge quality of the BOPP tape. At Flexibond, we use high-precision slitting machines equipped with automatic tension control and edge guiding systems. This ensures that each roll is cut accurately, with clean edges and consistent width.

Quality Control Measures

In-Process Inspections

Quality control at Flexibond is a continuous process that involves multiple in-process inspections. Our quality control team conducts regular checks at every stage of production to identify and address any deviations from the set standards. These inspections include:.

  • Visual Inspection: Checking for defects such as bubbles, streaks, or contamination on the film surface.
  • Dimensional Inspection: Measuring the thickness, width, and length of the film and tape to ensure they meet specifications.
  • Adhesion Tests: Conducting peel adhesion tests to verify the adhesive strength of the tape.
  • Tensile Tests: Measuring the tensile strength and elongation of the film to ensure it meets the required performance standards.

Laboratory Testing

In addition to in-process inspections, we have a fully equipped laboratory where we conduct more detailed testing of our BOPP tapes. Some of the key tests performed in our lab include:

  • Adhesion to Steel: Measuring the force required to peel the tape from a standard steel plate.
  • Holding Power: Assessing the tape’s ability to maintain adhesion under constant load.
  • Tackiness: Evaluating the initial stickiness of the tape.
  • Aging Tests: Simulating long-term storage conditions to assess the tape’s durability and performance over time.
  • Environmental Testing: Exposing the tape to different environmental conditions (temperature, humidity) to evaluate its performance.

Final Inspection

Before shipping, every roll of BOPP tape undergoes a final inspection to ensure it meets our quality standards. This includes checking the roll diameter, core alignment, and overall appearance. Any rolls that do not meet our criteria are rejected and reprocessed.


At Flexibond, we maintain complete traceability of our products. Each roll of BOPP tape is labeled with a unique batch number that allows us to trace it back to the raw material lot and production parameters. This traceability ensures accountability and helps us quickly address any quality issues that may arise.

Continuous Improvement

Quality control is not a one-time process but a continuous effort. At Flexibond, we are committed to continuous improvement in all aspects of our operations. We regularly review our processes, gather feedback from customers, and invest in the latest technologies and training for our staff. This proactive approach helps us stay ahead of the competition and consistently deliver high-quality BOPP tapes.

Commitment to Sustainability

As a responsible BOPP tape manufacturer in India, Flexibond is also committed to sustainability. We have implemented various measures to reduce our environmental impact, including:

  • Waste Management: Minimizing waste generation during production and recycling scrap materials.
  • Energy Efficiency: Using energy-efficient machinery and optimizing production processes to reduce energy consumption.
  • Eco-Friendly Materials: Using water-based adhesives and other environmentally friendly materials in our products.

Customer Satisfaction

Our ultimate goal at Flexibond is to ensure customer satisfaction. We understand that our customers rely on our BOPP tapes for their critical packaging needs, and we take this responsibility seriously. By maintaining stringent quality control measures and continuously improving our processes, we ensure that our customers receive products that meet their expectations.


Flexibond’s dedication to quality control in BOPP tape production sets us apart as a trusted BOPP tape manufacturer in India. Our comprehensive quality control measures, from raw material selection to final inspection, ensure that every roll of tape meets the highest standards of performance and reliability. With a commitment to continuous improvement and sustainability, we aim to provide our customers in Gujarat and across India with the best BOPP tape solutions.
