Common additives <strong>include<\/strong>: tacklers. Colorants. UV stabilizers. Based on customer needs, our lab precisely determines the formula proportions. Then, we begin professional extrusion production.<\/p>\n\n\n\n<p><strong>Extrusion extrusion<br><\/strong>We use imported twin-screw extrude to heat the plastic mixture to<strong> 180\u2013220\u00b0C<\/strong> until melted, then extrude it through <strong>precision molds.<\/strong> <strong>Cast film <\/strong>adopts a flat die head. It then passes through chill rolls for shaping and a smoother surface. <strong>Blown film <\/strong>is blown into bubbles using a ring die. We monitor the bubble diameter and thickness in real time and control the tolerance within \u00b15% to ensure consistent quality.<\/p>\n\n\n\n<p><strong>Cooling (Air Ring \/ Rollers) Cooling (air ring \/ chill rolls)<br><\/strong>The cast film is<strong> cooled<\/strong> and <strong>cured <\/strong>quickly by the<strong> chill rollers<\/strong>. Blown film is cooled by an <strong>air ring blowing cold air<\/strong>. This quickly shapes the film and locks in <strong>high resilience.<\/strong> Every roll undergoes factory testing to meet standards.<\/p>\n\n\n\n<p><strong>Winding<br><\/strong>After the film is <strong>molded<\/strong>, it needs to be <strong>wound and packaged.<\/strong> It is wound on a <strong>paper core<\/strong>. This ensures easy transportation and storage while maintaining tension and surface flatness.<\/p>\n\n\n\n<p><strong>Slitting<br><\/strong>After winding, the film is slit according to the customer&#8217;s needs. We offer various widths. To meet diverse customer needs.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-theme-palette-9-color has-theme-palette-1-background-color has-text-color has-background has-link-color has-border-color has-theme-palette-9-border-color has-fixed-layout\"><thead><tr><th>Process<\/th><th>Key Equipment<\/th><th>Temp\/Parameters<\/th><th>Quality Control<\/th><\/tr><\/thead><tbody><tr><td>Formulation<\/td><td>Lab<\/td><td>Precise ratios<\/td><td>Customized<\/td><\/tr><tr><td>Extrusion<\/td><td>Twin-screw extruder<\/td><td>180\u2013220\u00b0C<\/td><td>Cast\/blown dies<\/td><\/tr><tr><td>Cooling<\/td><td>Chill rolls\/air ring<\/td><td>Rapid curing<\/td><td>Thickness \u00b15%<\/td><\/tr><tr><td>Winding<\/td><td>Paper core winder<\/td><td>Maintain tension<\/td><td>Flat surface<\/td><\/tr><tr><td>Slitting<\/td><td>Slitter<\/td><td>Custom widths<\/td><td>Meet needs<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Introduction of Materials for Stretch Film Production<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Polymer Types<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Linear Low Density Polyethylene (LLDPE): <\/strong>This is a popular material for stretch film.

benefits that packaging does not. It has excellent stretch properties, puncture resistance, and availability. It can transport goods securely.<\/p>\n\n\n\n<p>Above all, it can help you reduce your cost of ownership. Stretch film packaging can be scaled down to lower sizes than regular plastic packaging. This means that more material is saved. Are-stretched film uses at least 45% less material than regular stretch film. A significant cost reduction.<\/p>\n\n\n\n<p>Secondly, stretch film protects the goods. During transportation, the film wraps tightly around the goods and prevents them from shifting. The strong performance keeps the product safe from damage. It also stops dust and moisture, and it cuts down on UV damage and gas contamination.<\/p>\n\n\n\n<p>In addition, stretch film can help customers enhance the aesthetics of packaging. Custom-printed icons, high transparency, and high gloss add a visual advantage to your packaging.<\/p>\n<\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-kadence-pane kt-accordion-pane kt-accordion-pane-2 kt-pane4137_f5b177-2d\"><div class=\"kt-accordion-header-wrap\"><button class=\"kt-blocks-accordion-header kt-acccordion-button-label-show\" type=\"button\"><span class=\"kt-blocks-accordion-title-wrap\"><span class=\"kt-blocks-accordion-title\">Is \u201cshrink film\u201d the same as \u201cstretch film\u201d?<\/span><\/span><span class=\"kt-blocks-accordion-icon-trigger\"><\/span><\/button><\/div><div class=\"kt-accordion-panel kt-accordion-panel-hidden\"><div class=\"kt-accordion-panel-inner\">\n<p>No. Shrink film utilizes the chemical properties of the film. Shrink film uses heat to trigger its heat-shrink properties, causing it to contract snugly around the product. Stretch film utilizes the physical properties of the film. It is usually \u201core-stretched\u201d or stretched and re-wrapped using a pallet wrapper. There are no chemical heat shrink properties involved. Stretch film packaging uses the film&#8217;s strength and controlled tension. This is linked to how well layers seal and how items are loaded. The two are not the same product; the applications are different. A detailed understanding of the differences between the two is necessary in order to make a more appropriate choice.<\/p>\n<\/div><\/div><\/div>\n<\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>What is stretch film?
