Excellent Stretch Film Machine Roll 500mm 10-20kg

Product Overview

This 500mm x 1000m x 30um roll is made for packing lines that need a clear machine-roll specification, not a broad weight range that changes from order to order. The 500mm width fits common wrapping carriages, and the 1000m length gives enough running distance for continuous pallet wrapping without making the roll difficult to load. The 30um gauge is useful when load holding, puncture resistance, and corner stress control are more important than reducing film thickness.

The film is produced from clear LLDPE cast stretch film, so carton labels, barcodes, and pallet identification remain visible after wrapping. It is normally supplied with a 76mm / 3 inch paper core for automatic wrapping machines and semi-automatic turntable wrappers. A typical machine roll weight can be checked around 15kg as a reference, but the final value should still be confirmed by net film weight, core weight, roll OD, winding tension, and batch record.

Before regular use, the roll should be tested on the actual wrapper. Edge flatness, smooth unwind, low blocking, and stable feeding through the carriage are more useful than thickness data alone. For repeat orders, a retained approved sample helps compare width, thickness, roll edge condition, unwind behavior, and pallet wrapping results.

Benefits

• Clear roll data for repeat purchasing: Fixed 500mm width, 1000m length, and 30um thickness make specification checks easier before machine loading.
• Smooth feeding through the carriage: Balanced winding tension, flat edges, and clean slitting help reduce sudden pulling and edge tearing.
• Stronger holding around dense loads: The 30um film helps secure export cartons, metal parts, profiles, and irregular unit loads.
• Better corner resistance: The thicker gauge helps where carton edges, uneven stacking, or stronger wrapping force may create stress.
• Clear visibility after wrapping: Operators can scan barcodes, read carton labels, and inspect the load without cutting open the wrap.
• Suitable for pre-stretch trials: The roll can be tested under moderate to high pre-stretch settings when tension, film path, and load shape are matched.

What Should Be Checked Before Using 500mm x 1000m Film on Heavy Pallets?

Before this 500mm x 1000m film is used for heavy pallet wrapping, the load shape and wrapper setting should be checked together. A 30um roll gives stronger puncture resistance than lighter gauges, but sharp carton edges, protruding parts, uneven stacking, or loose bottom layers can still create local stress points. During the first trial, operators should check film path, clamp position, overlap, top and bottom wraps, and corner tension. If breakage appears near pallet corners, the cause may come from load profile, excessive wrapping force, or an unsuitable pre-stretch setting rather than film thickness alone.

Applications

• Heavy carton pallet wrapping for stacked export cartons that need stronger holding force and corner stress control.
• Irregular unit loads with mixed shapes, uneven edges, protruding parts, or heavier product corners.
• Automatic wrapping lines where smooth feeding and repeatable cycles are important.
• Semi-automatic turntable wrappers used in warehouses, distribution centers, and packing stations.
• High pre-stretch packaging where film economy must be balanced with puncture resistance and load stability.
• Export pallet protection against dust, moisture exposure, handling vibration, and load shifting during transport.

How Should a 30um Machine Roll Be Matched to High Pre-Stretch Settings?

A 30um machine stretch film can work well on automatic and semi-automatic wrappers where stronger holding force and higher puncture resistance are needed, but the pre-stretch setting still has to match the film grade. If the rollers stretch the material too aggressively, the edge may become thin, tear during corner rotation, or break at the carriage before reaching the load. A practical approval test should start with moderate pre-stretch and wrapping force, then increase only when the film feeds smoothly and the pallet remains stable. The right setting is the point where film use is controlled, load compression is even, and no crushing, neck-down, edge tearing, or repeated breaks appear.

FAQ

1. Is this stretch film 500mm x 1000m 30 micron suitable for hand wrapping?

It is designed as a machine roll. Hand use is not recommended because the roll weight, 76mm core, and 1000m length are intended for carriage handling.

2. What type of wrapper can use this 30um film?

It is suitable for many automatic and semi-automatic stretch wrappers using 500mm wide rolls and 76mm / 3 inch paper cores. A wrapping trial should confirm carriage fit, film path, pre-stretch setting, and feeding stability.

3. Why use 30um thickness instead of a thinner gauge?

30um film is selected when heavy loads, irregular edges, higher holding force, and stronger puncture resistance are more important than using the lightest gauge.

4. What should be checked before repeat batch use?

Width, thickness, roll weight, core condition, roll OD, unwind smoothness, edge flatness, barcode visibility, break point review, and trial wrapping performance should be compared with the retained approved sample.
