The resulting package safeguards wood veneers, pre-hung frames, and painted surfaces against dust, moisture infiltration, and abrasive damage during warehouse stacking and rough transport.<\/p>\n<hr \/>\n<h2>How it works<\/h2>\n<p>The operating cycle coordinates continuous horizontal product transfer with synchronized vertical sealing and convective heat shrinking.<\/p>\n<table>\n<thead>\n<tr>\n<th>Process Step<\/th>\n<th>Subsystem<\/th>\n<th>Mechanical Action<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Feed<\/strong><\/td>\n<td>Infeed Belt \/ Roller Conveyor<\/td>\n<td>The door or panel transfers horizontally onto the conveyor bed, aligning with the line centerline.<\/td>\n<\/tr>\n<tr>\n<td><strong>Cover<\/strong><\/td>\n<td>Dual Film Unwind Carriages<\/td>\n<td>Top and bottom rolls feed continuous PE film across the line, draping film over the leading edge and faces.<\/td>\n<\/tr>\n<tr>\n<td><strong>Seal<\/strong><\/td>\n<td>Upper Pneumatic \/ Servo Sealing Frame<\/td>\n<td>The heated upper frame lowers under controlled pressure to weld and cut the film sleeve around the product perimeter.<\/td>\n<\/tr>\n<tr>\n<td><strong>Index<\/strong><\/td>\n<td>Step-Cycle Intermediate Transfer<\/td>\n<td>The frame retracts vertically; the conveyor advances the product forward in indexing steps for wide or long pieces.<\/td>\n<\/tr>\n<tr>\n<td><strong>Shrink<\/strong><\/td>\n<td>Forced Hot-Air Recirculation Tunnel<\/td>\n<td>The enclosed product moves into the shrink chamber where balanced heat shrinks the PE film tightly across all contours.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>For extended door panels exceeding the longitudinal span of the sealing frame, the system executes step-indexing: the conveyor indexes incrementally, allowing the sealing bar to complete overlapping segment seals before conveying the component into the shrink tunnel.<\/p>\n<hr \/>\n<h2>Film width<\/h2>\n<p>Calculating correct film web width prevents loose packaging, structural edge puncture, and film burn-through during thermal shrinking.

For example, a 900 mm wide by 40 mm thick door requires approximately 1,080 mm roll width using a 50 mm bilateral seal margin.<\/p>\n<h3>Can it pack panels as well as doors?<\/h3>\n<p>Yes. Both hollow and solid-core passage doors, architectural wall panels, and engineered wood boards can run across the same machine provided the dimensions fit within the maximum sealing aperture and shrink chamber cross-section (e.g., up to 1250 mm width).<\/p>\n<h3>What data sizes the line for solid doors?<\/h3>\n<p>Width, length and thickness, the 10\u201390 kg unit mass range, pieces per hour, and any surface-sensitivity constraint.<\/p>\n<h3>Does a thicker door need wider film?<\/h3>\n<p>Yes. Film wraps continuously around both lateral edges. Every additional 1 mm of panel thickness adds exactly 2 mm to the required flat film roll width.<\/p>\n<h3>What happens after sealing?<\/h3>\n<p>Once the film sleeve is cut and hermetically sealed around the product, the motorized conveyor indexes the loose package into a convective hot-air shrink tunnel. Controlled thermal recirculation causes the PE film to contract uniformly against the faces and perimeter edges.<\/p>\n<hr \/>\n<h2>Next step<\/h2>\n<ol>\n<li><strong>Send line data:<\/strong> maximum panel dimensions, weight range and required cycle time to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Get the sizing proposal:<\/strong> layout, film consumption projection and quotation within 24 to 48 hours.<\/li>\n<li><strong>Fix the integration:<\/strong> line height, upstream feed and footprint are agreed before build.<\/li>\n<\/ol>\n<hr \/>\n<h2>Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/solution\/door-shrink-wrap-machine.html\">Door shrink wrap machine technical solution<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/wooden-board-door-plate-shrinking-packaging-machine\/\">Video: door and wooden board shrink wrapping machine<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-door-wrapping-machine-stretch-wrapper\/\">Video: door wrapping machine with a horizontal orbital wrapper<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/door-shrink-packing-machine\/\">Door shrink packaging machine line overview<\/a><\/li>\n<\/ul>\n<hr \/>\n<h2>Sources<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/Door-shrink-packing-machine\/Door-shrinking-machine-with-motion-sealer.html\">Door shrinking machine with motion sealer<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Door-shrink-packing-machine\/Economic-type-door-shrink-packing-machine.html\">Economic type door shrink packing machine<\/a><\/li>\n<li>Machine in action: <a href=\"https:\/\/www.youtube.com\/watch?v=vXfk93ePOzQ\">Door packaging machine<\/a><\/li>\n<li>Machinery Safety Directives: <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> 2026-11-05<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive Summary: Door and panel shrink packaging systems protect finished surfaces and structural edges from moisture, abrasion, and transit handling between the factory and the job site.
