What is Tackifier and Why is it in Stretch Film?
Stretch wrap may be a term used for the film used with stretch wrapping machines to secure a load of fabric to a pallet making a unitized or single, solid, moveable object that arrives at its destination in needless to say condition.

Stretch Film For Machine Use |
Stretch film extruders add a range of compounds to the stretch film so as to deliver the required performance characteristics moreover on building it simple to method the film within the machines that square measure applying it, the stretch wrappers. one amongst the key additives is tackifier.
So what's tackifier?
A tackifier may be a bonding agent applied as an associate degree additive layer to the stretch film throughout the extrusion method (taking solid polymers and creating them liquified so as to make them into a movie or tube). This bonding agent layer is that the mechanism that delivers hold close to the film.
OK, thus what's cling?
Cling is that the property of the 'stickiness' of the film. In alternative words, what proportion a layer of the film adheres to the layer below and on top of it.
Tackifier accustomed to develop a cling layer are often applied to at least one aspect of the film, either side of the film at an equivalent level, or to either side of the film with a different level, that means adding on one aspect and fewer on the opposite leading to completely different levels of cling on both sides.
When the film is extruded it's wound on a middle core sometimes made of compressed fibrous paper material. Films coated on one aspect or with a differential tackifer cling layer sometimes have arrows written on the core to indicate that aspect has the cling layer additional or that one has the upper level.

These arrows direct the stretch wrapper operator to properly load the film onto the wrapper.
Usually, the cling layer on one aspect coated roll and therefore the higher cling layer on a differential role is towards the within or towards the core of the roll. Cling applies to the unrolling method moreover thus a neat film roll with unwind simply and cling powerfully once wrapped around a pallet load.
One approach to see however the way the roll is built is to tug back the film from the roll and stick one aspect to itself, if it sticks along then that's the cling layer. If the layer doesn't continue itself then it's not the cling layer (or additional extremely coated cling layer on a differential roll).
The opposite aspect of the cling coin is that the idea of slip. The non-tackifier aspect of a stretch film is usually designed to own low slip or to permit 2 wrapped masses to slip past or over each other while not protrusive, even though there a major force applied between the 2 masses.
Most LLDPE stretch films have a level of slip low enough that they're going to not bond along and can slide over each other if they are available into contact. If pallet masses should slide over each other then a movie with a high slip additive aspect could be the correct selection.
Cling may be a nice property as long because the stretch wrappers square measure discovered right and therefore the right film is specified. Threading film onto a stretch wrapper film delivery system and golf shot the cling layer within the incorrect orientation may be a mistake operator do not before long forget.
