For a 300 \u00d7 250 mm bundle cross-section, select a 550 mm minimum film web.<\/p>\n<p>Q: Which model takes the largest bundle?\nA: The SK-080B, up to 420 \u00d7 350 \u00d7 300 mm.<\/p>\n<p>Q: How many packs per minute can the system deliver?\nA: 8\u201318 packs per minute on models SK-075C, SK-080A, and SK-080B; 10\u201320 packs per minute on the smaller SK-060ABS.<\/p>\n<p>Q: Can it operate as a purely trayless shrink bundler?\nA: Yes. The system runs with or without trays; leaving out the tray saves material whenever the stack holds its shape.<\/p>\n<p>Q: What is the connected power requirement?\nA: Up to 8 kW on the SK-060ABS and up to 20.5 kW on the SK-080A.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<p>We plan your sleeve shrink bundler in three steps:<\/p>\n<ol>\n<li><strong>Submit your layout drawing<\/strong> and product parameters (dimensions, stack configurations, target line output) to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Receive a formal technical proposal within 48 hours<\/strong>, with the model and film width.<\/li>\n<li><strong>Book a site survey<\/strong> to plan infeed and outfeed.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/Bundle\/bundle-sleeve-080A.html\">Sleeve shrinking machine SK-080A<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Bundle\/bundle-sleeve-060ABS.html\">Shrink bundling machine SK-060ABS<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Bundle\/bundle-sleeve-080B.html\">Sleeve shrinking machine SK-080B<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-profile-and-panel-bagging-and-shrinking-line\/\">Video: automatic profile and panel bagging and shrinking line<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/carpet-roll-shrinking-machine\/\">Video: carpet roll shrinking machine<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>SK-060ABS technical data: <a href=\"https:\/\/www.fhopepack.com\/Bundle\/bundle-sleeve-060ABS.html\">shrink bundling machine SK-060ABS page<\/a><\/li>\n<li>SK-075C technical data: <a href=\"https:\/\/www.fhopepack.com\/Bundle\/bundle-sleeve-075C.html\">sleeve shrinking machine SK-075C page<\/a><\/li>\n<li>SK-080A technical data: <a href=\"https:\/\/www.fhopepack.com\/Bundle\/bundle-sleeve-080A.html\">sleeve shrinking machine SK-080A page<\/a><\/li>\n<li>SK-080B and SK-080E technical data: <a href=\"https:\/\/www.fhopepack.com\/Bundle\/bundle-sleeve-080B.html\">SK-080B page<\/a>, <a href=\"https:\/\/www.fhopepack.com\/Bundle\/bundle-sleeve-080E.html\">SK-080E page<\/a><\/li>\n<li>Machine operational validation: <a href=\"https:\/\/www.youtube.com\/watch?v=udGT69NEhsQ\">our bundle sleeve shrinking video on YouTube<\/a><\/li>\n<li>Harmonized safety standards: <a href=\"https:\/\/www.iso.org\/standard\/51528.html\">ISO 12100:2010<\/a>, <a href=\"https:\/\/www.nen.nl\/en\/nen-en-415-10-2014-en-191845\">EN 415-10:2014<\/a><\/li>\n<\/ul>\n<p><strong>Last reviewed:<\/strong> 2026-10-29<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary Our SK sleeve shrinking machines feed, wrap, seal, shrink, and cool bundled products in a single continuous automated line, supporting both trayed and trayless configurations.
