The world is usually looking for products that are inexpensive but have a long service life. More punctual but inexpensive utility. People choose affordable projects with high returns or performance on a given investment or payment method; products that are more reliable and convenient but do not require high rates. Stretch film or stretch wrap is one of the materials that people use daily to load, store or transport items.
It is the safest and most likely to be used for product packaging. Stretch film is considered the most popular method in pallet packaging. Everyday consumers and even large companies in the market have proved this. It can effectively prevent dust, moisture, debris and even dirty hands, and has a variety of uses in matching load applications. This is a very “multifaceted” type of packaging. There are two manufacturing processes for stretched films: casting and blow molding. These two have their unique characteristics. Cast stretch film (also known as cast stretch packaging) is manufactured using a cast extrusion process.
First, the pelletized resin is fed into the heated screw barrel. It has a continuous process through which the material is melted and extruded onto the cooling roll through a flat die, where it is then cooled and solidified again. The blown stretch film or blown film is manufactured using a blown film extrusion process. The plastic melt is extruded to form a thin-walled tube. The air passes through the hole in the center of the mold and blows up the tube like a balloon. Air blows onto the film to cool it down. This makes the blown film tougher and more elastic, and due to its higher mechanical properties, this gives the film greater retention and higher tear resistance, which can isolate objects from sharp objects. The manufacturing process of cast stretch film makes the film have higher transparency.
It has less drafting force, has excellent grip and can relax quietly. Its increased clarity allows consumers to see the packaged items more clearly. It has excellent optical effects, clear and shiny. Its tear resistance, adhesion and film width are consistent. Generally, because the manufacturing cost is lower, the cost is lower, but you can ensure that you get higher performance. In order to find the most cost-effective way of Slitting Stretch Film Manufacturer packaging, it can now be stored and even transported safely. Cast Stretch film definitely meets consumer satisfaction standards. Basically, due to the low cost of Cast Stretch film, this makes it a stretch film widely used in the market, and most people regard it as an economical and quality-wise packaging film. Its manufacturing process concept continues to improve because it has the cheapest production method.
