Kind Reminder

Dear customers, please pay attention to the following when using Seal King’s tape for the best bag breaking effect.
1. For different bag thicknesses, please refer to the applicable damage tape width recommended by the Seal King’s Permanent Bag Sealing Tape directory
2. It is recommended that the corona surface of PE bag is greater than 36 dyne
3. When pasting PE bags, pay attention to the cleanliness of the PE bag surface. If there are dust and other foreign objects, the bag will be broken. (It is recommended that the roller before rushing can be wrapped in cloth and dipped in alcohol, which will help clean the surface of the PE bag)
4. When pasting PE bags, pay attention to whether the tape is folded in half due to squeeze, which makes the glue width insufficient, resulting in poor effect of breaking the bag.
5. During the test, it is recommended to stick the tape for at least 10 to 60 seconds. The longer the paste, the better the effect is.
6. Note that if too much opening agent is added to PE bags, it may also affect the effect of breaking the bag.
It is recommended to test whether it is applicable before making a bag, or contact Seal King’s sales department to provide you with the best service, thank you!
