These directly affect throughput, film cost per unit, and floor space required.<\/strong> Additional criteria include film tension adjustability (measured in newtons per centimeter\u2014roughly the force of a small spring stretched across one centimeter of film width) and changeover time between furniture sizes. All values must be verified against the supplied product size list (length \u00d7 width \u00d7 height \u00d7 weight). Throughput and film consumption are highly dependent on product dimensions; a larger sofa will reduce packs per hour and increase film usage per unit.<\/p>\n<p>The evaluation is based on the original content, which specifies a baseline of three conveyors plus one sealing station and one shrinking (or wrap) station. Below are the two common configurations seen in the supplier\u2019s offerings. Both use automatic film feeding and PLC control.<\/p>\n<h2>\ud83c\udfd7\ufe0f Option A: Sealing &amp; Stretch Wrapping Line<\/h2>\n<iframe width=\"100%\" height=\"420\" src=\"https:\/\/www.youtube.com\/embed\/0XLvIWzWXYQ?rel=0\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<p><strong>This configuration uses a sealing station to bag the sofa in a polyethylene film, then a stretch wrapping station that applies a tight film layer under adjustable tension. Typical film thickness ranges from 20 to 50\u202f\u00b5m, and the sealing speed is 60\u201380 bags per hour for standard sofa dimensions (length \u2264\u202f2000\u202fmm).<\/strong> The stretch wrapper applies film with a pre\u2011stretch ratio of 200\u2013300%, meaning the film is stretched to two or three times its original length before being applied, reducing film consumption by up to 40% compared to manual wrapping.<\/p>\n<p><strong>Key Point:<\/strong> The film tension can be set between 10 and 50\u202fN\/cm (newtons per centimeter of film width) to avoid damaging fabric. For reference, 10\u202fN\/cm is approximately the force needed to stretch a small spring one centimeter; 50\u202fN\/cm is a firm tension suitable for heavy upholstery. The conveyor system is rated for 500\u2013800\u202fkg per linear meter of belt, suitable for heavy sofas (e.g., a 2\u202fm sofa can bear up to 1600\u202fkg evenly distributed). No heat tunnel is required, reducing energy consumption to about 5\u20138\u202fkW total for the line. The footprint is typically 12\u201318\u202fm long by 3\u20134\u202fm wide (approximately 50\u201370\u202fm\u00b2). Seal strength is verified through a peel test (pulling sealed layers apart and measuring force per unit width), which should be performed with your actual film and product.<\/p>\n<p>This option is best for sofas that need breathable packaging (not air\u2011tight) and where stretch film cost is a priority. It also allows easy removal of film at the destination.<\/p>\n<h2>\ud83d\udcc8 Option B: Sealing &amp; Shrink Wrapping Line<\/h2>\n<p><strong>This configuration uses a sealing station to bag the sofa in a heat\u2011shrinkable film (typically PVC or polyethylene), then a shrink tunnel where hot air (180\u2013220\u202f\u00b0C) shrinks the film tightly against the furniture. Typical shrink speed is 50\u201370 packs per hour for sofas up to 2200\u202fmm length. Film thickness is 30\u201380\u202f\u00b5m, with a shrink ratio of 50\u201370%.<\/strong> The shrink tunnel consumes 20\u201335\u202fkW of power per hour, and the line footprint is slightly larger due to the tunnel length (15\u201322\u202fm long by 3\u20134\u202fm wide, about 60\u201390\u202fm\u00b2).<\/p>\n<p><strong>Key Point:<\/strong> The result is a skin\u2011tight, dust\u2011proof, moisture\u2011resistant package. However, film cost per unit is typically 15\u201325% higher than stretch film because shrink film is thicker and cannot be pre\u2011stretched. The heat process may require a cooling conveyor or waiting time before stacking to prevent film distortion. Conveyor load rating is the same as Option A (500\u2013800\u202fkg\/m). Seal integrity is tested similarly via a peel force measurement, but must account for the additional sealing of the shrink tunnel\u2019s bottom seal (if present).<\/p>\n<p>This option is preferred for sofas that will be stored outdoors or in humid environments, or where product visibility is important (clear shrink film). It can also combine a bottom seal for complete dust protection.<\/p>\n<h2>\ud83d\udee1\ufe0f Comparison Table<\/h2>\n<table>\n<thead>\n<tr>\n<th>Criterion<\/th>\n<th>Option A: Sealing + Stretch Wrapping<\/th>\n<th>Option B: Sealing + Shrink Wrapping<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Typical throughput (sofa \u2264\u202f2\u202fm)<\/strong><\/td>\n<td>60\u201380 packs\/hour<\/td>\n<td>50\u201370 packs\/hour<\/td>\n<\/tr>\n<tr>\n<td><strong>Film thickness range<\/strong><\/td>\n<td>20\u201350\u202f\u00b5m (linear low\u2011density PE)<\/td>\n<td>30\u201380\u202f\u00b5m (PVC or cross\u2011linked PE)<\/td>\n<\/tr>\n<tr>\n<td><strong>Film pre\u2011stretch ratio<\/strong><\/td>\n<td>200\u2013300%<\/td>\n<td>0% (no stretch)<\/td>\n<\/tr>\n<tr>\n<td><strong>Film cost per unit (example)<\/strong><\/td>\n<td>Lower (~$0.03\u20130.06\/m\u00b2)<\/td>\n<td>Higher (~$0.05\u20130.10\/m\u00b2)<\/td>\n<\/tr>\n<tr>\n<td><strong>Energy consumption<\/strong><\/td>\n<td>5\u20138\u202fkW total line<\/td>\n<td>20\u201335\u202fkW (shrink tunnel)<\/td>\n<\/tr>\n<tr>\n<td><strong>Footprint (L\u202f\u00d7\u202fW)<\/strong><\/td>\n<td>12\u201318\u202fm \u00d7 3\u20134\u202fm (~50\u201370\u202fm\u00b2)<\/td>\n<td>15\u201322\u202fm \u00d7 3\u20134\u202fm (~60\u201390\u202fm\u00b2)<\/td>\n<\/tr>\n<tr>\n<td><strong>Moisture\/dust protection<\/strong><\/td>\n<td>Moderate (film can loosen over time)<\/td>\n<td>High (skin\u2011tight, heat\u2011sealed edges)<\/td>\n<\/tr>\n<tr>\n<td><strong>Film tension control<\/strong><\/td>\n<td>Adjustable 10\u201350\u202fN\/cm (PLC)<\/td>\n<td>No tension control (shrink shrinks evenly)<\/td>\n<\/tr>\n<tr>\n<td><strong>Changeover time<\/strong><\/td>\n<td>10\u201315\u202fmin (adjust film width)<\/td>\n<td>15\u201320\u202fmin (change film + tunnel temp)<\/td>\n<\/tr>\n<tr>\n<td><strong>Typical application<\/strong><\/td>\n<td>Indoor storage, short transit<\/td>\n<td>Outdoor storage, long transit, high humidity<\/td>\n<\/tr>\n<tr>\n<td><strong>Maintenance requirement<\/strong><\/td>\n<td>Low (fewer heating elements)<\/td>\n<td>Moderate (heaters, fans, sensors)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><em>Note: All figures are based on typical supplier specifications and must be verified against your actual product dimensions, film types, and operating conditions. Throughput and film consumption will vary with product size.<\/em><\/p>\n<h2>\u2699\ufe0f Selection Advice<\/h2>\n<p><strong>Choose the stretch wrapping line (Option A) if you prioritize lower per\u2011unit film cost, lower energy bills, and faster throughput for standard indoor storage. Choose the shrink wrapping line (Option B) if your furniture must survive outdoor shipping, high moisture, or requires a waterproof, tamper\u2011evident seal.<\/strong> A general decision principle is to compare the total cost of ownership (film + energy + maintenance + labor) against the risk of product damage. For example, if your annual packaging film budget is a significant cost driver, stretch wrapping typically provides a lower cost per pack. Conversely, if moisture\u2011related returns exceed 2% of revenue, investing in shrink wrapping may reduce losses.<\/p>\n<p>For mixed furniture sizes, both lines allow quick changeover (10\u201320\u202fmin) provided you supply a size list (length, width, height, weight) as requested by the supplier. The original content recommends sending a table with dimensions\u2014essential for customizing conveyor widths and film roll sizes.<\/p>\n<blockquote>\n<p><strong>Tip:<\/strong> Always request a sample run with your actual sofa dimensions. The supplier video shows a complete three\u2011conveyor, sealing, and shrinking line. Test both film types to confirm seal strength (using a peel test that measures the force required to separate sealed layers, typically reported in newtons per centimeter) and film tear resistance.<\/p>\n<\/blockquote>\n<h2>\ud83d\udee0\ufe0f Purchase\u2011Decision Checklist<\/h2>\n<ul>\n<li>\n<p>[ ] Confirmed product size range (length \u2264\u202f2500\u202fmm? width \u2264\u202f1200\u202fmm? height \u2264\u202f1000\u202fmm?)<\/p>\n<\/li>\n<li>\n<p>[ ] Determined annual packaging volume to compare film + energy + labor cost (throughput and film consumption are based on your specific dimensions)<\/p>\n<\/li>\n<li>\n<p>[ ] Measured available floor space: at least 12\u202fm \u00d7 4\u202fm for stretch, 15\u202fm \u00d7 4\u202fm for shrink<\/p>\n<\/li>\n<li>\n<p>[ ] Checked power supply: 380\u202fV\/50\u202fHz typical (verify with supplier)<\/p>\n<\/li>\n<li>\n<p>[ ] Requested video of both lines running your product type<\/p>\n<\/li>\n<li>\n<p>[ ] Asked for a cost\u2011benefit analysis (e.g., payback period in months, based on your actual packaging costs\u2014no generic ROI formula is provided here)<\/p>\n<\/li>\n<\/ul>\n<blockquote>\n<p>\ud83d\udee1\ufe0f <strong>Compliance Note<\/strong>: This equipment is designed to meet ISO and ASTM requirements.
