Both options are evaluated based on the supplied conveyor length of 4.0\u202fm \u00d7 3 sets, a package range of 1\u201310 panels, and a constant-temperature heat-shrink tunnel that seals film in a typical range of 160\u2013200\u202f\u00b0C. Each criterion is scored as \u201cmeets\u201d, \u201cexceeds\u201d, or \u201cfalls short\u201d for a typical 8\u2011hour shift. The comparison assumes the machine can handle 75\u202fkg packages without stacking automation\u2014a capability that should be confirmed with the supplier\u2019s load specification.<\/p>\n<h2>\ud83c\udfd7\ufe0f Option A: Automatic Packing Line with Integrated Stacker<\/h2>\n<p><strong>This configuration includes the shrink\u2011wrap tunnel plus a fully automatic stacking robot that builds bundled loads up to 1500\u202fmm height, operating at a typical speed of up to 12 packages per minute.<\/strong> The mechanical principle of stack alignment uses a servo\u2011driven pusher that shifts each packed panel onto a waiting pallet. A photo\u2011eye array checks edge alignment before the next layer is added. The constant\u2011temperature heat\u2011shrink sealing section maintains film tension by pre\u2011heating the polyethylene wrap to a typical setpoint around 180\u202f\u00b0C (request the supplier\u2019s published specs for exact control accuracy). A side\u2011seal bar closes the film longitudinally while a cross\u2011seal jaw completes the bag. The integrated stacker then transfers the bundle to an exit roller table.<\/p>\n<p><strong>Key Point: The stacking robot reduces manual handling by at least two operators per shift.<\/strong> However, the floor space required increases by approximately 3\u202fm \u00d7 2\u202fm for the gantry frame and control cabinet\u2014these dimensions are from one configuration and may vary. Installation cost is typically 15\u201320\u202f% higher than Option B, based on the supplier\u2019s 15\u2011year experience with 50+ customized PIR machines (request documented evidence from the supplier). If your production volume exceeds 400 packages per shift, this option may pay back within an estimated 12\u201318 months under typical labour cost assumptions (wage rates, shift hours\u2014verify with your own costs). The stacker can handle panel heights from 40\u202fmm up to 200\u202fmm by adjusting the pick\u2011and\u2011place gripper stroke.<\/p>\n<h2>\ud83d\udcc8 Option B: Automatic Packing Line without Stacker<\/h2>\n<p><strong>This line uses the same constant\u2011temperature shrink tunnel and conveyor system but requires one or two workers to manually stack the sealed packages onto a pallet.<\/strong> The mechanical principles of the shrink\u2011seal section are identical to Option A: the film passes through a servo\u2011driven unwind roller, a side\u2011seal unit, and a temperature\u2011controlled hot\u2011air knife that keeps the film in a typical range of 160\u2013200\u202f\u00b0C. The panel enters the tunnel at a typical speed of 2\u202fm\/min (verify configuration with supplier), and the film shrinks uniformly around the stack. After exit, a simple lifting table (2\u202fm long) lets the operator stack packages.<\/p>\n<p><strong>Key Point: Labour requirement is 1\u20132 people per shift, which increases yearly cost by roughly USD\u202f30,000\u201345,000 (based on unspecified assumptions about wage rates and shift hours\u2014request localised estimates from the supplier).<\/strong> Floor space is smaller (only 1\u202fm additional for the lifting table), and the capital investment is lower by about USD\u202f20,000\u201330,000 (illustrative range; request quotation). For low\u2011volume producers (under 200 packages per shift) or where labour is readily available, this option is the most direct path to automated wrapping without the complexity of a stacker. The supplier\u2019s original quotation (based on the inquiry) assumed Option B because the customer stated \u201cNo, we do not need the stacking machine.\u201d<\/p>\n<h2>\ud83d\udee1\ufe0f Comparison Table<\/h2>\n<table>\n<thead>\n<tr>\n<th>Criterion<\/th>\n<th>Option A (Integrated Stacker)<\/th>\n<th>Option B (Manual Stacking)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Throughput (packages\/shift)<\/strong><\/td>\n<td>400\u2013600 (robot paces conveyor)<\/td>\n<td>200\u2013350 (operator limited)<\/td>\n<\/tr>\n<tr>\n<td><strong>Labour required per shift<\/strong><\/td>\n<td>0 operators for stacking + 1 for supervision<\/td>\n<td>1\u20132 operators full\u2011time<\/td>\n<\/tr>\n<tr>\n<td><strong>Floor space addition<\/strong><\/td>\n<td>3\u202fm \u00d7 2\u202fm (gantry + control) \u2014 one configuration; may vary<\/td>\n<td>1\u202fm \u00d7 2\u202fm (lifting table)<\/td>\n<\/tr>\n<tr>\n<td><strong>Capital investment premium<\/strong><\/td>\n<td>+15\u201320\u202f% over base shrink line (estimate)<\/td>\n<td>Base price (per quotation)<\/td>\n<\/tr>\n<tr>\n<td><strong>Film seal consistency<\/strong><\/td>\n<td>Identical (same tunnel)<\/td>\n<td>Identical (same tunnel)<\/td>\n<\/tr>\n<tr>\n<td><strong>Flexibility for panel height 40\u2013200\u202fmm<\/strong><\/td>\n<td>Automatic gripper adjustment (\u226410\u202fs change)<\/td>\n<td>Manual adjustment of stop fence (\u22642\u202fmin)<\/td>\n<\/tr>\n<tr>\n<td><strong>Maintenance complexity<\/strong><\/td>\n<td>Higher (servo\u2011driven robot, sensors)<\/td>\n<td>Lower (only linear actuators)<\/td>\n<\/tr>\n<tr>\n<td><strong>Payback period (vs. Option B)<\/strong><\/td>\n<td>12\u201318 months (estimate under typical labour cost assumptions)<\/td>\n<td>Immediate (no extra investment)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><em>All values are illustrative estimates based on the supplied conveyor lengths, panel dimensions, and typical PIR production environments.

If your volume is below 80,000 packages per year and you have reliable workers, Option B avoids the upfront premium and keeps the line simple.<\/p>\n<p><strong>Key Point: The constant\u2011temperature heat\u2011shrink tunnel is the same in both options \u2013 it is the stacking decision that drives labour or investment.<\/strong> Ask your supplier to run a simulation with your actual shift hours and local labour rate. Based on the inquiry data (75\u202fkg max, 1\u201310 panels per package), both configurations can handle the load. If you plan to expand production later, consider a modular conveyor that can later be retrofitted with a stacker gantry. Many manufacturers (including the one in the original video) offer upgrade kits.<\/p>\n<h2>\ud83d\udee0\ufe0f Purchase-Decision Checklist<\/h2>\n<ul>\n<li>\n<p>[ ] Confirm your <strong>max package weight<\/strong> (supplied: 75\u202fkg) and <strong>panel dimensions<\/strong> (2000\u20134000\u202fmm \u00d7 1200\u202fmm \u00d7 40\u2013200\u202fmm).<\/p>\n<\/li>\n<li>\n<p>[ ] Determine <strong>shift target<\/strong> (packages per hour \/ per day).

The tunnel keeps the film in the 160\u2013200\u202f\u00b0C range regardless of stack height, but the conveyor speed may need tweaking for very thin (40\u202fmm) stacks to avoid overheating the edges. Exact control parameters should be confirmed with the supplier.<\/p>\n<p><strong>Q: Can I upgrade a manual\u2011stack line to automatic later?<\/strong><br \/>\nA: Usually yes. The conveyor base and film supply section are standard; a stacker gantry can be bolted on with a control extension. Discuss modularity with your supplier and request detailed interface specifications.<\/p>\n<p><strong>Q: What is the typical film\u2011seal rejection rate?<\/strong><br \/>\nA: Based on the supplier\u2019s claim, properly tuned machines maintain a rejection rate below 0.5\u202f% from mis\u2011sealing. This is the supplier\u2019s unpublished data; we recommend asking for documented evidence or test reports. The constant\u2011temperature system is key to that reliability.<\/p>\n<p><strong>Q: Do I need a special permit to import this machine to Bangkok?<\/strong><br \/>\nA: Standard machinery import requires HS code 8422.40 (packaging machinery) and Thailand customs clearance. The supplier should provide a CE declaration and origin certificate.
