ShengWei machines fill any premade flat-bottom bag from your converter regardless of which term your packaging team uses &mdash; bag converters typically use \"K-seal\" in technical specs while marketing uses \"block-bottom\" or \"flat-bottom\" on the bag itself.<\/p>\n          <\/div>\n        <\/details>\n\n        <details class=\"sw-bt-faq__item\">\n          <summary>Can I add a one-way degassing valve for whole-bean coffee?<\/summary>\n          <div class=\"sw-bt-faq__answer\">\n            <p>Yes. Degassing valves are pre-applied to the bag by your bag converter (not by the filling machine) before bags are loaded. The SW-D series rotary fillers accept any flat-bottom pouch with or without valve &mdash; no machine modification needed. Specify \"valve-ready bag\" with your converter and ship samples to us for sealing test before commitment.<\/p>\n          <\/div>\n        <\/details>\n\n        <details class=\"sw-bt-faq__item\">\n          <summary>Why is flat-bottom more expensive than stand-up or gusset?<\/summary>\n          <div class=\"sw-bt-faq__answer\">\n            <p>The K-seal welded base requires more film material and more bag-converter steps than a stand-up pouch&rsquo;s simple folded gusset or a side-gusset&rsquo;s side panels. Per-bag film cost runs roughly 20&ndash;35% higher than equivalent <a href=\"\/stand-up-pouch-packing-machine\/\">stand-up pouch<\/a> at the same fill weight. For trial sizes and single-serve sachets, <a href=\"\/3-side-seal-pouch-packing-machine\/\">3-side seal<\/a> is the cheapest format. The flat-bottom premium is justified for high-shelf-presence SKUs (specialty coffee, premium tea, infant formula) where the rigid-box appearance commands a higher retail price.<\/p>\n          <\/div>\n        <\/details>\n\n        <details class=\"sw-bt-faq__item\">\n          <summary>Can I add a zipper to a flat-bottom pouch?<\/summary>\n          <div class=\"sw-bt-faq__answer\">\n            <p>Yes &mdash; resealable zippers are common on premium loose-leaf tea, sport-nutrition powder, and infant-formula flat-bottom pouches. The zipper is added by your bag converter; SW-D \/ SW-L machines include a zipper-opening station as a standard module that detects, opens, fills below, and reseals the top.
