The film around a coil has to stretch over the outer edge, cling to the surface, and resist puncture when the coil is handled or stacked.<\/p>\n<p>The right film keeps dust and moisture from the metal while the package stays intact through storage and sea freight. The film grade is confirmed per project.<\/p>\n<h2 id=\"how-the-film-is-applied\">How the film is applied<\/h2>\n<p>A coil wrapping machine applies the film automatically: a film-carrying arm lowers over the coil, the coil rotates on the conveyor, and film unwinds around the outer edge in even passes.<\/p>\n<p>Because the machine controls the motion, the film tension and the number of layers stay consistent from coil to coil. Coil size and wrap profile are confirmed per project.<\/p>\n<h2 id=\"film-width-and-grade-for-coils\">Film width and grade for coils<\/h2>\n<p>Film width should cover the coil edge in the planned number of wraps, so wider coils need wider film or more passes. The film grade, in turn, balances cling, stretch and puncture resistance for the coil edge.<\/p>\n<p>Film width, thickness and grade are all confirmed per project with the coil dimensions you send.<\/p>\n<h2 id=\"wrap-pass-and-overlap-plan\">Wrap pass and overlap plan<\/h2>\n<p>The wrap plan defines how many times the film passes around the coil and how far each pass overlaps the previous one. More passes add protection and use more film; the right setting depends on how far the coil travels and how it is handled.<\/p>\n<p>Wrap passes and overlap are confirmed per project with the coil and route details.<\/p>\n<h2 id=\"what-the-footage-shows\">What the footage shows<\/h2>\n<p>Our footage shows a flat annular metal coil on a roller conveyor at the wrap station of an automatic coil wrapping machine. A film-carrying arm lowers from above while the coil rotates, and stretch film is laid over the coil edge in even passes, after which the wrapped coil moves downstream.<\/p>\n<p>A mesh safety fence encloses the moving parts, and a control cabinet sits at the side of the line. It is a general demonstration, so your coil size, film grade and wrap plan are confirmed with us per project.<\/p>\n<h2 id=\"typical-configuration\">Typical configuration<\/h2>\n<p>Figures below list functional design boundaries rather than numeric values, and are confirmed per project.<\/p>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Parameter<\/th>\n<th style=\"text-align: left\">Typical range, confirmed per project<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Load<\/td>\n<td style=\"text-align: left\">flat annular metal coil on the wrapping conveyor<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Coil geometry<\/td>\n<td style=\"text-align: left\">outer diameter and width in mm, center eye size<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Film apply<\/td>\n<td style=\"text-align: left\">arm lowers and lays film over the coil edge<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Film<\/td>\n<td style=\"text-align: left\">stretch film grade, width and gauge<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Wrap<\/td>\n<td style=\"text-align: left\">passes around the coil and overlap per pass<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Rotation<\/td>\n<td style=\"text-align: left\">coil rotates on the conveyor during wrapping<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Transfer<\/td>\n<td style=\"text-align: left\">downstream conveyor for the wrapped coil<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Electrical supply<\/td>\n<td style=\"text-align: left\">380 V three phase 50 Hz, or 220 V single phase for light machines, selected per project<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"selection-checklist\">Selection checklist<\/h2>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Question<\/th>\n<th style=\"text-align: left\">Confirm per project<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Film purpose<\/td>\n<td style=\"text-align: left\">dust and moisture protection, or rust protection with VCI grade film<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Coil size<\/td>\n<td style=\"text-align: left\">outer diameter, width and eye size of the coil<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Film width<\/td>\n<td style=\"text-align: left\">width matched to the coil edge and wrap plan<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Wrap passes<\/td>\n<td style=\"text-align: left\">number of passes around the coil and overlap<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Handling<\/td>\n<td style=\"text-align: left\">storage indoors or outside, distance of transit<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Electrical supply<\/td>\n<td style=\"text-align: left\">voltage, phase and frequency on site<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"operation-and-safety\">Operation and safety<\/h2>\n<p>Load a coil on the wrapping conveyor, set the film roll on the arm, and start the cycle so the coil is wrapped before it moves downstream.
