4 Unknown Facts About Stretch Film Converting
iSellPackaging
Basically, the actual manufacturing process is termed as extrusion. In the process melting and forming forms the major part for the production of stretch film resin. It ends with a master roll, which is then converted to a variety of stretch film sizes. Now it is time to look for some unknown facts, find out them here.
It needs unwinding of master Roll
As stated earlier, the extrusion process ends up with creating a large master roll. Thus, in order to convert it into a stretch film, it requires unwinding the roll. Now, the master roll can differ in size and width. Hence, it can take time to convert into a specific size. Businesses need to learn that often it takes around 2 to 5 day lead time for film conversion.
Converting Machines and Electronic Length Counters
In order to enable the converters to adjust the roll lengths as per the film thickness, electronic length counter are employed. Here it is important to note that thicker stretch films are often shorter rolls than the thinner film. And this is the reason which helps to keep the overall weight of the roll comparable. For the buyers, these electronic roll counters need to be extremely accurate. This simple assures you that the customers get the desired length of film.
Conversion limits and Restricted core Sizes:
It is the size of the core. Basically, the core is the cardboard which is present on the inside of the roll of stretch film and are sent to stretch film converters. Now the buyers need to know that a stretch film converter is limited to the size of rolls. Hence, requesting an oddball width, for example, 2.75 inch wide, would need the production of a core size in that width. While it is difficult, it would cost you too high.
The pre-stretch Stretch Film During the conversion process of a pre-stretch, stretch film is usually pulled from the master roll and it is then stretched up to 90% of available stretch-ability. Later, it is placed on a smaller roll. This pre-stretch film turns out to be a great option for the companies. The reason being, the film is stretched prior the placement on a roll. Hence, the workers need to exert less energy. Along this, an added advantage is that it is much cheaper option.
Hence, now whenever you buy these films, you need to keep these points in mind and make efficient use of the. Website: iSellPackaging.com Email. ID: DWeiss@glopackllc.com Phone: (516) 353-0398
