Double adhesive tape for permanent bonding with a support of 12 microns thick polypropylene, covered with a high-performance synthetic rubber adhesive. The liner with which the adhesive tape is protected is made of bioriented polypropylene (BOPP), silicone, which can be hot cut and exceeds the edges of the adhesive so as to allow an easy remove, after application, even with two fingers (finger-lift). This protective material (liner) from BOPP can be delivered in three different colors: blue, red and transparent. The tape can be delivered in both roll and roll.
The tape has been designed, in particular, for the permanent closure (sealing) of polyethylene and polypropylene bags/sacks where a more efficient bonding is required than that obtained with 3813 F tape (ex: large thickness and co-extruded bags). The protective material (liner) from bioriented polypropylene allows it to be cut at low temperatures, and the adhesive makes a permanent bonding to polyethylene and other thin plastics. Due to the thickness differences of the polyethylene and polypropylene bags, the tape must always be tested before use. For very thin LDPE / HDPE bags, you must take care when removing the protective material (liner) from the tape. It always grabs from the middle of the tape.
