PSA emulsion, the main ingredient is butyl. BOPP sealing tape specifications with the "length × width × thickness", where "W" is the width of the tape, usually expressed in mm or cm, general ≥10mm, as early as 80 years ago, the common specifications are: 72mm, 60mm, 50mm, 30mm, etc; Now, it has been gradually replaced by: 60mm, 48mm, 45mm, 40mm, 30mm, etc; "length" is the total length of the tape opened later, usually with "m" or "code" indicates (1 yard = 0.9144m), a common length of 50m, 100m, 150m, 200m, 500m, etc; BOPP the original film thickness refers to the total thickness of the layer + (unit: m, um), commonly used 45 ~ 55um. Such as "50mm × 100m × 50um". BOPP sealing tape is suitable for BOPP film to the substrate, the substrate is coated with a layer of pressure-sensitive adhesive side of the tape evenly. The tape is mainly used for sealing, capping and bundled items, etc., can also be used as office supplies.
