LLDPE Stretch Film

Linear low density polyethylene (LLDPE) is a substantially linear polymer, with significant numbers of short branches, commonly made by copolymerization of ethylene with longer-chain olefins.
LLDPE has higher tensile strength and higher impact and puncture resistance than LDPE. It is very flexible and elongates under stress. It can be used to make thinner films, with better environmental stress cracking resistance. It has good resistance to chemicals and to ultraviolet radiation. It has good electrical properties. However it is not as easy to process as LDPE, has lower gloss, and narrower range for heat sealing.
Stretch wrap is most commonly made of linear low density polyethylene, or LLDPE. Most of us know it as the material that secures pallets of individual containers. Pallet stretch wrap is used by product manufacturers and distributors to bind shipping cartons to pallets going to a warehouse/distribution center (W/DC). It is also used at the W/DC to wrap pallets sent to outlets/customers.

Types of stretch film
Cast Stretch Film
Cast stretch film also called cast film or cast wrap, is manufactured using the cast extrusion process. Typical characteristics of cast stretch films are: excellent optics, clear, glossy, superior tear resistance, quiet unwind, consistent cling and consistent film thickness. Cast stretch film products: hand stretch wrap film - cast, machine stretch wrap film - cast.

Blown Stretch Film
Manufactured using the blown film extrusion process and also referred to as blown film. Typical blown strecth film characteristics are: poor optics, hazy, dull, excellent puncture resistance, very noisy unwind and high force on load. See products: hand stretch wrap- blown

Hand Stretch film
Stretch film designed specifically to be applied manually is referred to as hand stretch film. It is also referred to as hand film, hand stretch wrap, hand wrap or manual pallet wrap. It is typically utilized in lower capacity packaging operations. However the efficiency of manual stretch wrap packaging should be regularly re-evaluated against potential benefits of upgrading to a machine wrapper. Choosing the right stretch applicator will result in more efficient and cost effective packaging operations. See products: hand stretch film - cast , hand stretch film - blown, prestretched hand film.

Machine Stretch film
Stretch film designed to be applied with a stretch wrap machine is referred as machine stretch film. It provides many advantages over hand film including: faster and more efficient packaging, reduced packaging material costs, safer application, more secure loads and more. Common machine stretch film types: cast machine stretch film, blown machine film and prestretched films. See products: machine stretch wrap film - cast and prestretched.

Prestretch films
Prestretched film is film that is stretched before wrapping a load. Prestretch film benefits include:
Reduced amount of film used, so film costs are greatly reduced
Requires less revolutions to wrap a load, saving time, more efficient
Less packaging film means less waste to clear and dispose
Prestretch films are recycable
Prestretched film is strong, consistent and stable
