An <a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-aluminum-film-applicator-and-bag-packing-line-video\/\">automated film applicator and bag packing line<\/a> feeds PE film off a reel, a bag-forming station shapes it around the bundle, and a sealing bar closes the seam. The pack then passes through a shrink tunnel that tightens the film against the profile surfaces.<\/p>\n<p>The film is applied without touching the profiles until it shrinks in the tunnel, so anodized and painted surfaces come away without scuffs from the packaging step. Sealing and tunnel settings are stored as recipes, which lets the line switch between profile sizes without re-programming every changeover.<\/p>\n<h2 id=\"profile-coverage\">Profile coverage<\/h2>\n<p>The standard machine suits profile lengths from 1000 to 8000 mm, and extended layouts reach 12000 mm on request. Bundle width and height adapt to the profile configuration rather than being fixed, and the standard weight limit is 15 kg per bundle, with heavy-duty variants rated for 25 to 50 kg. The tunnel length and weight-class selection are confirmed per project, matched to your line speed and bundle mass.<\/p>\n<h2 id=\"line-architecture\">Line architecture<\/h2>\n<p>The line is arranged as four stations under one PLC + HMI control.<\/p>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Component<\/th>\n<th style=\"text-align: left\">Function<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Film unwinding<\/td>\n<td style=\"text-align: left\">feeds PE film with adjustable tension, 300 to 800 mm film width<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Bag forming<\/td>\n<td style=\"text-align: left\">shapes film around the bundle, servo-driven, \u00b12 mm positioning<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Sealing bar<\/td>\n<td style=\"text-align: left\">closes the bag, 120 to 200\u00b0C, PLC controlled<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Shrink tunnel<\/td>\n<td style=\"text-align: left\">applies heat, adjustable conveyor 0 to 15 m\/min<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"technical-parameters\">Technical parameters<\/h2>\n<p>The table lists the published typical values of the reference machine.

With that schedule the expected MTBF exceeds 8000 operating hours.<\/p>\n<p>Operator training takes 2 to 4 hours and covers HMI use, routine maintenance and the safety routine, so a new operator handles the line in part of a shift.<\/p>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: What shrink film works for aluminium profiles?\nA: PE shrink film at 30 to 80 \u00b5m covers typical bundles. For heavy bundles or outdoor storage, use cross-linked PE or POF for puncture and UV resistance.<\/p>\n<p>Q: Can the line switch between profile lengths?\nA: Yes. The PLC stores 50 or more recipes, and changeover with pre-saved parameters is under 5 minutes.<\/p>\n<p>Q: How does tunnel temperature affect the pack?\nA: Keep the tunnel between 140 and 180\u00b0C. Too low leaves the film loose; too high risks tearing or surface damage. PID control holds \u00b12\u00b0C.<\/p>\n<p>Q: What is the cycle rate?\nA: 8 to 15 cycles per minute, configurable to the production line.<\/p>\n<p>Q: What training is needed?\nA: No specialized programming skills are required. A standard 2 to 4 hour commissioning covers recipe recall, film reel rethreading and safety resets, with manuals and video tutorials provided.<\/p>\n<p>Q: What maintenance keeps it reliable?\nA: Daily seal-bar cleaning and film alignment, weekly conveyor checks and lubrication, monthly sensor calibration, with MTBF above 8000 hours.<\/p>\n<p>Q: What finishes can the line process without scuffs?\nA: Anodized, powder-coated, PVDF and mill-finish surfaces all pass clean, because the film shapes around the bundle without rubbing profiles before shrinking.<\/p>\n<p>Q: What air and power does the line need?\nA: 380 V \/ 50 Hz, configurable from 220 to 480 V 50\/60 Hz, and a pneumatic supply of 0.5 to 0.8 MPa.<\/p>\n<h2 id=\"next-step\">Next step<\/h2>\n<ol>\n<li>Email us at info@fhopepack.com with your profile lengths, bundle weights and target speed.<\/li>\n<li>We send a layout drawing and bagging line proposal within 48 hours.<\/li>\n<li>We arrange a site survey to confirm the footprint and utility supply.<\/li>\n<\/ol>\n<h2 id=\"related-reading\">Related reading<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-tape-binding-machine-for-box\/\">Automatic tape binding machine for box<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-backpacking-and-shrinking-line\/\">Automatic backpacking and shrinking line<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/semi-automatic-aluminum-profile-packing-machine-wrapping-machine\/\">Aluminum profile packaging machine, wrapping line<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/videos\/automatic-orbital-stretch-wrapper-with-bubble-film-covering-for-door-panel-furniture\/\">Automatic orbital stretch wrapper with bubble film covering for door panel<\/a><\/li>\n<li><a href=\"https:\/\/www.fhopepack.com\/Products\/\">FHOPE packaging machinery product lines<\/a><\/li>\n<\/ul>\n<h2 id=\"sources\">Sources and standards<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.iso.org\/standard\/51528.html\">ISO 12100:2010 \u2014 Safety of machinery.
