It moves into the machine, where clear protective film comes down from the roll above and guide and press rollers lay it over the door.<\/p>\n<p>The covered door enters the heating chamber through white strip curtains. Inside, rows of heating tubes shrink the film tight into the panel recesses and round the frame as the door runs on the rollers. The door leaves onto the outfeed rollers with the film set. A control panel with red buttons and a small screen sits at the exit side.<\/p>\n<h2 id=\"how-it-works\">How the door shrink cycle works<\/h2>\n<table>\n<thead>\n<tr>\n<th>Stage<\/th>\n<th>What happens<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Infeed<\/td>\n<td>The door lies flat on the infeed conveyor<\/td>\n<\/tr>\n<tr>\n<td>Film cover<\/td>\n<td>Film from the roll is laid over the door<\/td>\n<\/tr>\n<tr>\n<td>Heat tunnel<\/td>\n<td>Heating tubes shrink the film tight<\/td>\n<\/tr>\n<tr>\n<td>Outfeed<\/td>\n<td>The film sets on the outfeed rollers<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Strip curtains at the tunnel ends keep the heat inside, so the film shrinks evenly along the door. For our own door line, see our <a href=\"https:\/\/www.fhopepack.com\/videos\/wooden-board-door-plate-shrinking-packaging-machine\/\">wooden board door plate shrinking packaging machine<\/a>; for long profiles and panels, see our <a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-profile-and-panel-bagging-and-shrinking-line\/\">automatic profile and panel bagging and shrinking line<\/a>.<\/p>\n<h2 id=\"tunnel\">Sizing the heat tunnel<\/h2>\n<p>The door must spend enough time in the heat for the film to shrink fully. Illustrative example:<\/p>\n<table>\n<thead>\n<tr>\n<th>Item<\/th>\n<th>Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Longest door (illustrative)<\/td>\n<td>2,100 mm<\/td>\n<\/tr>\n<tr>\n<td>Time in heat needed<\/td>\n<td>Set by film and tunnel temperature, confirmed on trial<\/td>\n<\/tr>\n<tr>\n<td>Heated length<\/td>\n<td>Conveyor speed \u00d7 time in heat<\/td>\n<\/tr>\n<tr>\n<td>Tunnel length<\/td>\n<td>Longer than 2,100 mm and than the heated length<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>We set the tunnel longer than your longest door so the whole door is in the heat at once. Film type and tunnel temperature also change the time in heat, so we confirm it on trial.<\/p>\n<h2 id=\"doors\">Door types and what to tell us<\/h2>\n<table>\n<thead>\n<tr>\n<th>Door type<\/th>\n<th>What to tell us<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Panelled doors<\/td>\n<td>Depth of the recesses<\/td>\n<\/tr>\n<tr>\n<td>Flush doors<\/td>\n<td>Width, length and thickness<\/td>\n<\/tr>\n<tr>\n<td>Glazed doors<\/td>\n<td>Whether the glass needs extra protection<\/td>\n<\/tr>\n<tr>\n<td>Mixed sizes<\/td>\n<td>The largest and smallest door<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Deeper recesses need more shrink, so we set film and heat on trial with your doors.<\/p>\n<h2 id=\"safety\">Controls and safety<\/h2>\n<p>The heating chamber is hot and the rollers carry the door through it. Keep hands out of the tunnel and off the rollers while the machine runs, and clear a jam only when it has stopped and cooled.<\/p>\n<p>The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 sets general requirements for packaging machines.<\/p>\n<h2 id=\"selection-checklist\">Selection checklist for a door shrink film machine<\/h2>\n<ul>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Door width, length and thickness, smallest to largest.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Panel recess depth.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Doors per hour.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Film type and thickness.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Hand or automatic feeding.<\/li>\n<li style=\"margin-left:-1.25em;list-style-type:none\"><input type=\"checkbox\" disabled=\"disabled\" \/> Floor space and power supply.<\/li>\n<\/ul>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: How does the film get into the panel recesses?\nA: The heat tunnel shrinks it tight into the recesses and round the frame.<\/p>\n<p>Q: How long should the tunnel be?\nA: Longer than the longest door, so in our 2,100 mm door example the tunnel is longer than 2,100 mm.<\/p>\n<p>Q: What sets the time in heat?\nA: Conveyor speed and heated length: time in heat = heated length \u00f7 conveyor speed.<\/p>\n<p>Q: Why are there curtains at the tunnel ends?\nA: They keep the heat inside so the film shrinks evenly.<\/p>\n<p>Q: Can one machine pack different doors?\nA: Yes, when the film and tunnel suit the largest and smallest door.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<p>We plan your door shrink film machine in three steps:<\/p>\n<ol>\n<li><strong>Submit your layout drawing<\/strong> with door sizes and output to <strong>info@fhopepack.com<\/strong>.<\/li>\n<li><strong>Receive a proposal within 48 hours<\/strong>, with the film and tunnel plan.<\/li>\n<li><strong>Book a site survey<\/strong> to check the line layout and floor space.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/solution\/door-shrink-wrap-machine.html\">Door shrink wrap machine<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/door-and-panel-shrink-packaging-machine\/\">Video: door and panel shrink packaging machine<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/wooden-board-door-plate-shrinking-packaging-machine\/\">Video: wooden board door plate shrinking packaging machine<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources<\/h2>\n<ul>\n<li>Solution content: FHOPE engineering team, 2026-10-04<\/li>\n<li>Tunnel example: our worked example, illustrative values<\/li>\n<li>Machine in action: <a href=\"https:\/\/www.youtube.com\/watch?v=omp72CraJ6Y\">the video on YouTube<\/a><\/li>\n<li>Standards scope: <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> 2026-10-04<\/p>","protected":false},"excerpt":{"rendered":"<p>Executive summary Panelled wood doors need film that pulls tight into every recess, so the faces and edges stay clean from the factory to the building site.
