Jumbo Roll Stretch Film 500mm X 20 kg For Safe Packing

Product Overview

The lldpe stretch film jumbo roll is made for companies that cut and rewind large film stock into finished stretch film products. Stretch strength is only one checkpoint. The mother stock also needs to sit firmly on the shaft, release smoothly, keep clean edges, and stay stable during continuous slitting.

During sample conversion, a weak core may compress, uneven ends can affect alignment, and unstable unwind tension may cause wrinkles, telescoping, loose winding, uneven hardness, or higher edge waste. A short rewinding trial is more useful than judging only by appearance.

Common widths include 300mm, 400mm, 450mm, and 500mm. A 500mm width is often used for standard hand or machine roll production, while 300mm and 400mm stock can reduce trimming loss for smaller sizes or private-label carton packs. The 26-55kg jumbo weight range is confirmed by thickness, roll diameter, core strength, and loading method. Net film weight should be checked after deducting paper core weight, and roll OD should be confirmed before semi-automatic or high-speed rewinding. Transparent, black, and colored film support resale, privacy, grade separation, or channel control.

Benefits

• LLDPE cast film gives stable stretch, cling, and converting behavior.
• Jumbo mother stock improves output before finished roll production.
• 300mm, 400mm, 450mm, and 500mm widths fit different slitting plans.
• 26-55kg specification keeps the product positioned as jumbo stock.
• Thickness and net film weight checks support consistent repeat orders.
• Smooth unwind tension reduces breakage, wrinkles, telescoping, and loose winding.
• Flat ends and reinforced paper core improve loading, cutting, alignment, and storage stability.
• Transparent, black, and colored options support resale and market separation.

How Can Rewinding Factories Reduce Slitting Loss When Using LLDPE Stretch Film Jumbo Roll?

Slitting loss usually comes from several small issues working together. A rewinding factory should check clean film edges, stable unwind tension, consistent thickness across the web, and firm paper core support. An lldpe stretch film jumbo roll in 300mm, 400mm, 450mm, or 500mm width should match the finished size and trimming margin. If the roll-end surface is not flat, or if the core compresses under 26-55kg loading, the film can shift and create edge waste. Before repeat production, converters should record trimming waste, observe film breakage, compare finished roll hardness, and confirm that each color keeps similar tension behavior.

Applications

• Rewinding factories producing hand stretch film rolls from mother stock.
• Slitting workshops converting jumbo stock into smaller market sizes.
• Packaging material distributors preparing private-label finished products.
• Importers and wholesalers arranging local conversion from bulk master stock.
• Film converters producing transparent, black, or colored stretch film rolls.
• Suppliers making carton-packed hand or machine rolls for regional distribution.

What Should Be Checked Before a Jumbo Roll Enters Hand Roll or Machine Roll Rewinding?

Before master stock is approved for rewinding, the check should focus on converting behavior, not only stretch strength. Review LLDPE consistency, thickness stability, smooth cling, low blocking, roll-end flatness, and paper core strength. Uneven ends can affect cutting, alignment, and carton packing, especially when 26-55kg stock is loaded on high-speed or semi-automatic equipment. A short trial should confirm whether the film converts without wrinkles, telescoping, breakage, neck-in, loose winding, or trim loss. Net film weight, roll OD, finished roll hardness, edge waste, and core condition should be recorded for repeat-order consistency.

FAQ

1. Is this product the same as hand stretch film?

No. It is stretch film mother stock for rewinding and slitting, supplied to producers of finished hand or machine rolls.

2. What jumbo weight should be selected?

The common jumbo weight is 26-55kg. Selection depends on film thickness, roll diameter, paper core strength, loading method, net film weight target, and finished size.

3. Can transparent, black, and colored film be supplied?

Yes. Transparent film suits resale, black film supports privacy or light blocking, and colored film helps separate grades, warehouse categories, or channels.

4. How should the jumbo roll be tested before repeat production?

A short rewinding trial should check unwind tension, roll-end flatness, edge trimming loss, film breakage, wrinkles, telescoping, finished roll hardness, net film weight, roll OD, and paper core condition.
