1.BOPP is made from polypropylene, which is a thermoplastic polymer. The film is stretched in both directions during manufacturing, resulting in enhanced strength, clarity, and dimensional stability. This stretching process aligns the polymer molecules, making the tape more resistant to tearing and puncturing.
2.Commonly used adhesives for BOPP packing tape include hot melt synthetic rubber and acrylic water-based adhesives. Hot melt adhesives offer quick sealing, strong bonding, and reliability. They adhere well to various surfaces and provide excellent holding power. Acrylic adhesives, on the other hand, have better resistance to temperature extremes, oxidation, and humidity, making them suitable for use in harsh environmental conditions.
3.BOPP packing tape has a relatively high tensile strength, allowing it to withstand significant pulling forces without breaking. This property is crucial for ensuring that packages remain securely sealed during handling, transportation, and storage.
4.The tape is known for its excellent clarity and high gloss, which gives a professional and clean look to the sealed packages. Transparent BOPP tape is often preferred for shipping and sealing applications where visibility of the package contents or labels is desired.
5.It exhibits outstanding dimensional stability, meaning it does not easily stretch, shrink, or warp. This ensures that the tape maintains its shape and position on the package, providing a consistent and reliable seal.
