The standard production envelope accommodates workpieces 900\u20132,400 mm in length, 200\u20131,200 mm in width, 100\u2013800 mm in height, and 20\u2013100 kg in mass, with ring operating speeds continuously adjustable between 10\u201360 r\/min.<\/p>\n<\/blockquote>\n<iframe loading=\"lazy\" width=\"940\" height=\"535\" src=\"https:\/\/www.youtube.com\/embed\/mCAnNuUA64g\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<hr \/>\n<p>This automated packing line pairs a heavy-duty horizontal orbital stretch wrapper with an inline dual-web bubble film covering station mounted on high-durability green PVC belt conveyors. The covering unit holds motorized top and bottom bubble film unwind rolls, sealing the leading and trailing ends in a rigid pneumatic frame. As the flat panel advances seamlessly along the belt, the integrated ring frame wrapper applies protective tensioned stretch film. System parameters, temperature loops, and inverter drives are managed via an integrated digital control cabinet.<\/p>\n<h2 id=\"table-of-contents\">Table of Contents<\/h2>\n<ul>\n<li><a href=\"#why-two-layers\">Why bubble film plus stretch film<\/a><\/li>\n<li><a href=\"#covering\">Bubble film covering station<\/a><\/li>\n<li><a href=\"#wrapping\">Orbital stretch wrapping station<\/a><\/li>\n<li><a href=\"#specs\">Specifications<\/a><\/li>\n<li><a href=\"#example\">Worked example: 2,000 mm panel<\/a><\/li>\n<li><a href=\"#selection-checklist\">Selection checklist<\/a><\/li>\n<li><a href=\"#safety\">Safety: EN 415-10 and ISO 12100<\/a><\/li>\n<li><a href=\"#engineering-faq\">Engineering FAQ<\/a><\/li>\n<li><a href=\"#next-step\">Next step<\/a><\/li>\n<li><a href=\"#related-reading\">Related reading<\/a><\/li>\n<li><a href=\"#sources\">Sources<\/a><\/li>\n<\/ul>\n<h2 id=\"why-two-layers\">Why bubble film plus stretch film<\/h2>\n<p>Flat panels, architectural doors, precision furniture parts, insulated glass assemblies, and powder-coated metal extrusions are vulnerable to both localized dynamic impacts and abrasive scuffing during transit.<\/p>\n<ul>\n<li><strong>Bubble film<\/strong> provides high-resilience kinetic cushioning against side-impacts and drops, but as an unbound single layer, it tends to slide, unravel, and rupture around acute edges.<\/li>\n<li><strong>Stretch film<\/strong> delivers continuous hoop tension that compresses the bubble film tightly against the product geometry, provides a particulate-tight dust barrier, prevents edge migration, and stabilizes the bundle.<\/li>\n<\/ul>\n<p>Combining both packaging steps into a single continuous-feed line replaces multiple labor-intensive manual operations with a single, synchronized automated pass on the conveyor.<\/p>\n<h2 id=\"covering\">Bubble film covering station<\/h2>\n<ol>\n<li><strong>Positioning &amp; Optical Infeed.<\/strong> An industrial photocell sensor detects the incoming product&#8217;s leading edge, tracking conveyor positioning via encoder feedback to coordinate the covering sequence.<\/li>\n<li><strong>Dual-Web Encapsulation.<\/strong> Bubble film unrolls synchronously from dedicated upper and lower roll carriages. The workpiece enters between the two webs, producing consistent top and bottom cushioning coverage without manual draping.<\/li>\n<li><strong>Cross-Sealing &amp; Cutoff.<\/strong> A 1,400 mm constant-temperature heated sealing jaw welds the top and bottom bubble film webs across the leading and trailing edges while an integrated cutter severs the material cleanly. The thermal PID control maintains steady temperature to prevent film degradation or carbonized residue, backed by an anti-clamping safety protection mechanism to prevent accidental jaw closure on misaligned parts. The longitudinal open sides are subsequently secured and closed by the spiral stretch wrap layer (longitudinal heat-sealing can be configured on request for hermetic 6-sided containment).<\/li>\n<li><strong>Conveyor Transfer.<\/strong> The encapsulated product transitions directly onto the wrapping infeed conveyor.

Only the exterior LLDPE stretch film is applied spirally by the rotating orbital ring.<\/p>\n<p><strong>Q: Can this system run stretch film wrapping only, bypassing the bubble covering unit?<\/strong>\nA: Yes. The PLC interface includes independent operational modes: bubble covering only, stretch wrapping only, or combined sequence. When running stretch film alone, the product passes through the open covering frame without engaging the sealing jaw.<\/p>\n<p><strong>Q: What is the maximum load weight handled by the standard conveyor bed?<\/strong>\nA: The standard line handles continuous unit weights from 20 kg up to 100 kg. For heavy architectural panels, structural timber, or steel profiles exceeding 100 kg, reinforced roller beds and heavy-duty chain-driven conveyors can be integrated.<\/p>\n<p><strong>Q: How does the system prevent surface marking or micro-scratching on delicate glass or high-gloss furniture parts?<\/strong>\nA: The transport bed uses seamless industrial PVC belts rather than bare steel rollers. All vertical overhead press-down rollers and lateral guide wheels are sleeved with non-marking polyurethane or soft elastomer coatings to eliminate friction scuffing.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<ol>\n<li><strong>Submit Application Parameters:<\/strong> Send your product dimensions, maximum panel weights, surface characteristics, and desired line speed to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Engineering Layout &amp; Sizing:<\/strong> Our engineering team will calculate the required ring inner diameter, web width, and conveyor drive specifications.<\/li>\n<li><strong>Commercial Proposal:<\/strong> We provide an itemized engineering layout drawing and formal proposal within <strong>24 hours<\/strong>.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/Customize-orbital-wrapper\/bubble-film-wrapper.html\">Orbital stretch wrapper with bubble film covering device (product)<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-panel-wrapping-machine-packing-machine\/\">Automatic panel wrapping machine<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-door-wrapping-machine-stretch-wrapper\/\">Automatic door wrapping machine and stretch wrapper<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/combined-machine-for-six-sides-wrapping\/\">Combined machine for six sides wrapping<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/giant-horizontal-orbital-stretch-wrapping-machine-with-film-covering-unit\/\">Giant horizontal orbital stretch wrapping machine with film covering unit<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>FHOPE Technical Documentation: Automated Horizontal Orbital Wrapper with Dual-Web Film Covering Unit<\/li>\n<li>FHOPE Project Engineering File: E1200 Inline Bubble Film and Stretch Wrapping System (2023)<\/li>\n<li>EN 415-10: Safety of Packaging Machines \u2013 Wrapping Machines<\/li>\n<li>ISO 12100:2010: Safety of Machinery \u2013 General Principles for Design \u2013 Risk Assessment and Risk Reduction<\/li>\n<li>Production line video reference: FHOPE integrated bubble film wrapping unit shown above<\/li>\n<\/ul>\n<p><strong>Last updated:<\/strong> 2026-10-29<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive Summary An automated horizontal orbital stretch wrapping line provides integrated two-stage surface and impact protection for flat or profiled products in a continuous pass.
