Permanent Bag Sealing Tape is a BOPP polyester film differentially coated with a permanent (hot melt adhesive and acrylice adhesive) synthetic rubber adhesive system. The liner side (the tape exposed once you remove the liner) is coated with hot melt adhesive,exhibits high adhesion to a variety of surfaces, and has excellent destructive effect. The exposed side (the tape visible once you unwind it from the roll) is coated with acrylic adheisve which forms a long-term bond immediately upon contact. The liner on the tape can be easily removed because it has a non-adhesive or finger lift dry edge on each side of the tape.


Qichang Permanent bag sealing tapes are used by polyethylene converters and bag makers as an aggressive adhesive for the permanent sealing of paper envelopes, plastic bags, and laminating to low-slip and no-slip plastic films. This tape is commonly used for mailing bags, magazine bags, or any other PE bag requiring a permanent closure.
