“BOPP” means Biaxially Oriented Polypropylene — a plastic film that is stretched in two perpendicular directions, which gives it strength, durability, moisture- and abrasion-resistance. Many packing tapes use BOPP film as backing.
A “brown adhesive tape” (or “brown BOPP tape”) is a BOPP-film-based tape where the backing is colored brown (rather than transparent). It is coated with a pressure-sensitive adhesive (often water-based acrylic), so it sticks to cartons, boxes, packaging materials immediately when pressed.
Brown BOPP adhesive tapes are commonly used for carton sealing, packaging, shipping, storage, warehousing, logistics — anywhere you need a strong, reliable seal for cardboard boxes or parcels.
Because of BOPP + good adhesive, these tapes offer strong adhesion, high tensile strength, moisture & temperature resistance, consistent unwind and reliable sealing — making them a go-to tape for industrial/warehouse/commerce packaging.
In short: a BOPP brown adhesive tape is a standard packaging tape (carton sealing tape) — robust and industrial-grade — widely used by manufacturers, warehouses, logistic companies, retailers, e-commerce fulfilment, etc.
