The zipper-opening station adds 0.5&ndash;1&nbsp;second per cycle to detect, open, and re-seal above the zipper. On the <a href=\"\/premade-bag-packing-machine\/premade-bag-granule-packing-machine\/\">SW-D series<\/a> (rated 30&ndash;80 bags\/min for non-zipper bags), zipper bags run 25&ndash;70 bags\/min &mdash; about 10&ndash;15% slower. Speed loss is negligible for retail-volume production but worth noting for mass-market high-volume single-SKU runs.<\/p>\n          <\/div>\n        <\/details>\n\n        <details class=\"sw-bt-faq__item\">\n          <summary>Can I run K-seal stand-up pouches with a zipper?<\/summary>\n          <div class=\"sw-bt-faq__answer\">\n            <p>Yes. K-seal stand-up pouches (also called <a href=\"\/flat-bottom-pouch-packing-machine\/\">flat-bottom box pouches<\/a>) commonly carry a zipper for premium specialty coffee, loose-leaf tea, sport nutrition. The zipper-opening station handles K-seal pouches the same way as standard doypacks &mdash; you just need to specify K-seal bag template at quote stage so we set the gripper spacing correctly for the wider rectangular base.<\/p>\n          <\/div>\n        <\/details>\n\n        <details class=\"sw-bt-faq__item\">\n          <summary>What films work with zipper pouches?<\/summary>\n          <div class=\"sw-bt-faq__answer\">\n            <p>Standard premade-bag films &mdash; PET\/PE, PET\/AL\/PE foil laminate, kraft paper laminate, recyclable mono-PE\/PP, and metallized films from 60&ndash;150 micron thickness all support zipper application. The zipper itself is HDPE or PP, color-matched to the bag print. Ship sample bags with your zipper to our <a href=\"\/factory\/\">Guangdong factory<\/a> for a sealing test before order &mdash; we run the actual SW-D \/ L machine to verify zipper-opening reliability with your specific zipper-bag combination.<\/p>\n          <\/div>\n        <\/details>\n\n        <details class=\"sw-bt-faq__item\">\n          <summary>Lead time and payment terms?<\/summary>\n          <div class=\"sw-bt-faq__answer\">\n            <p>Standard lead time 25&ndash;35 working days from deposit confirmation to FOB Shantou for any of the 4 SW-D \/ L \/ Y \/ 130ZK machines &mdash; same window <a href=\"\/about-us\/\">ShengWei has held since 2003<\/a>.
