Self-adhesive bags with sticky tape, made of brand new OPP material, transparent with no odor, sealed with sticky tape, with a thickness of 12 threads on both sides. The size of the bag is the total size after laying flat (with a certain error), so if you remove the sticky tape and flip over the seal, the actual use length of the bag will be reduced by about 2-4cm (the larger the bag, the larger the length of the seal will be). Please calculate carefully before ordering, thank you. If the specifications and thickness are not what you want, we can provide custom business for you. Custom orders require a certain quantity and provide the required dimensions. Welcome to consult!
