Why is some BOPP Tape light yellow?

BOPP tape is suitable for ordinary product packaging, sealing and bonding, gift packaging, etc. Depending on the color, there are different uses. Transparent sealing tape is suitable for carton packaging, fixing of spare parts, binding of sharp objects, art design, etc. Colorful sealing tape provides a variety of color options, in line with different appearance, beautiful needs; Sealing tape can be used for international trade sealing, express logistics, online shopping malls and other well-known brands.

BOPP film itself is transparent, and ordinary transparent tape is light yellow, because it uses the glue – pressure sensitive glue, usually orange, beige, if daubed with a small amount, there is no change, but a lot of it, the color will deepen, especially the BOPP tape film layer by layer, will gradually show light yellow. And super transparent tape can do approximately colorless, and will not yellow, in addition to the use of a very good film, high transparency of the glue, after special glue processing, super transparent.

As the industry’s packaging requirements continue to improve, there are many scenes in which super clear tape can present better visual effects. It has the same performance as ordinary transparent tape, but its unique high transparency is not available to other tape.

For example, Raxwell super permeable box sealing tape with bidirectional stretching polypropylene film (BOPP film) as the base material, on the base material side evenly coated with a layer of pressure sensitive adhesive (acrylic glue). BOPP film colorless, tasteless, with excellent transparency, so this kind of tape is also called BOPP tape, transparent visibility is good, low fog point, can clearly see the texture behind.

Of course, poor quality and cheap film transparency is not high, and the glue is easy to yellow, will cause the whole volume looks yellow.
