What problems should we pay attention to when using glue tooth zipper?
(1) The pulling force should not be too large;
(2) When using the intubation and socket, insert the intubation into the bottom end of the socket cavity, and then pull the pull head;
(3) For the zipper on the bag, when there are too many things, if the zipper is hard pulled when closing and closing, the zipper will suffer too much force, which will separate the teeth from the belt parts. Pull the left and right teeth of the zipper closer to make the chain head pass easily, and then close the zipper slowly.
