Have you ever noticed that every time you buy sealing tape, the store will have to buy left or right glue. Customers who don't know will be very confused. When the tape is on the outside of a BOPP bag or PE bag, how can there be a difference between left and right glue?
First come to the difference between the left glue and the right glue of the lower sealing tape of popular science
The glue side is facing yourself, that is, the side where the glue is applied, facing yourself, pull the tape with your hand, the dividing point is directly above, the glue level on the left is left glue, otherwise it is right glue
According to the difference between the working principle of the hot-cutting bag-making machine and the half-folding machine, if the hot-cutting bag-making machine uses the right glue for gluing, the half-folding machine uses the left glue for gluing.
Under what circumstances do you apply glue on the hot-cutting bag-making machine? If the thickness of PE film, PP film, and BOPP film is less than 2, 3 filaments, stick tape on the hot-cutting bag-making machine.
On the contrary, on the folding machine, the thickness of the bopp film is more than 2, 3 filaments.
If you need more details on the role and scope of application of each machine, you can consult our staff at any time to provide you with more detailed answers.
