World is usually in quest of products that are not so expensive but last long; utilities that are more punctual in its line but does not charge that much.
People choose affordable items with high return or performance on the given investment or payment; products that are more reliable and convenient but does not require high rate.
Stretch film or stretch wrap is one of the materials that people usually use daily in load storing or in transporting items.
It is one of the safest and most likely to be utilized in product packing.
Stretch film is considered to be the most popular method in pallet wrapping.
It is proven by daily consumers and even big companies in the market.
It is effective in superior protection from dust, moisture, debris and even filthy hands, and is very versatile in fitting load applications.
It is a very "multifaceted" type of wrapping.
There are two manufacturing processes in Stretch Film: the Cast and the Blown processes.
These two have their own distinct characteristics.
Cast Stretch film, also called Cast Stretch wrap is manufactured using a cast extrusion process.
It starts by having granular resin fed into a heated screw barrel.
It has a continuous process by which a material is melted and extruded through a flat die onto a chill roll, where it is subdued and re-solidified.
Blown Stretch film or Blown film is manufactured using the blown film extrusion process.
This Plastic melt is extruded to form a thin walled tube.
Air goes through the hole in the center of the die to blow up the tube like a balloon.
Air blows onto the film to cool it.
This allows blown film to be tougher and more resilient and because of its Higher Mechanical Properties, this provides the film to have greater holding power, and a higher tear resistance securing the items from sharp objects.
But this will cost customers higher rate due to its manufacturing process, poor clarity due to crystallization, and it is noisy when unwound from rolls.
The manufacturing process of Cast Stretch film allows the film to have higher level of clarity.
It involves a smaller amount of force to stretch, has exceptional grip, and loosens quietly.
Its increased clarity allows consumers to see wrapped items clearer.
It has an excellent optics, clear and glossy.
Its rip resistance, cling and film width are all consistent.
Generally, it is less expensive due to less cost of manufacturing but assures you high level of performance.
Answered prayers! In your search for the most economically effective in packing your items, for safe storage or even in transportation is now available.
Cast Stretch film certainly meets consumers' satisfaction standards.
Basically, because of Cast Stretch film's low cost, this made it to be as the widely used stretch film in the market and most of the people would consider it as an Economy and Quality wise packing film.
Its manufacturing process' philosophy continuously increases because it has the cheapest possible method of production.
Its cost has always been its primary advantage.
