Stretch Film – Issues & Solutions

Technical Support Guide

At NPP, we want you to get the most from our stretch  film. That’s why we created this support guide. It allows you to quickly identify any issue which may be affecting your stretch film’s performance.

Issue Probable Cause Solution
Products are being crushed The film has been applied to tightlyToo much film has been applied Reduce the stretch level and/or increase the speed of feed
The load is shifting (at the base) The film has not been attached to the pallet base during wrappingThe film has been too loosely applied

Insufficient film has been applied

The load is too light for lay-on force used

Ensure the pallet is coveredIncrease the stretch level and/or reduce the speed of feed

Increase the number of turns

Increase the film thickness

Reduce the stretch level and/or increase the film thickness

The load is shifting (between layers) The film is too looseThe product is moving between layers Increase the stretch usedInterleave products with stretch wrap film or similar
The load is shifting (generally) The film is too looseThere is insufficient overlap

The film is too thin

Increase the stretch levelIncrease the overlap

Increase the film thickness

Pallet stretch wrap is torn The film is too thinThe film has been incorrectly applied and loads are sticking together Increase film thicknessBe sure your choice of film has ‘cling’ on only one side and that side is facing the load
The stretch wrap punctures over protrusions The lay-on force used exceeds the puncture resistance of your choice of film Reduce level of stretch and/or increase film thickness and/or use a higher grade of film
The stretch wrap tails off the pallet The film has insufficient tack/clingWipe down operations are not being performed properly Check the efficiency of the wipe down apparatus and/or select a film with higher cling
The film herring bones The film is too loose or soft Increase the level of stretch and/or increase the overlap and/or increase the film thickness. Alternatively, use a stiffer grade of film
The film tears The film edge is damagedThe film edge becomes damaged when stretched

The film is too sticky and will not unwind

Remove the damaged layersCheck and clean stretch rollers

Withdraw the film and replace

The film has holes The film is being damaged by the stretch mechanismThe film is contaminated

The film is too sticky and will not unwind

Check and clean the stretch rollersCheck the leading and trailing edges of the holes for contamination

Withdraw the film and replace

The film snaps There is excessive stretch damageThe film is contaminated

The film is to sticky and will not unwind

There is a machine malfunction

Reduce the stretch level. Also check the roll and stretch rollers for damageCheck the broken edges of film for contamination

Withdraw the film and replace
