B.Emergence of Stretch Films
Stretch films emerged in the 1950s as a response to the need for a more efficient and cost-effective solution to packing, storing, and shipping items. Stretch films like shrink film are a type of plastic film that is highly elastic and can be stretched to cover and hold items and pallet loads tightly together.
To accommodate various purposes in the stretch film market, the plastic film, which is constructed of linear low-density polyethylene (LLDPE), is produced in a range of widths and thicknesses. Cast stretch films are made to stick to an object’s surface and retain it there while protecting it from dust and moisture and maintaining the object’s tight bond with other objects.
A stretch film or a stretch wrap is used for a wide range of applications in any product’s shape, from food and beverage packaging to industrial and agricultural uses. Their versatility and durability make them a popular choice for many businesses in circular economy for product packaging.
C.Limitations of Early Stretch Films
Early stretch films had significant shortcomings, but the stretch film industry has recently made improvements. The biggest limitation of early stretch wrap was that it lacked elasticity and were prone to tearing when stretched too far. Additionally, stretch films are tended to be more expensive than other types of packaging materials. Stretch films were also more difficult to apply and could be difficult to resize or reposition if needed in materials.
Finally, a stretch film or a stretch wrap offered limited clarity and could be prone to fogging if exposed to moisture or high temperatures. New stretch films that have greater elasticity, better clarity, and ease of application have essentially solved these constraints.
Advancements in Stretch Film Technology
A.Introduction of Blown Film Extrusion
Using a machine stretch film, the method of blowing film extrusion produces plastic films and sheets from polymer pellets. This process involves melting the pellets and then extruding them through a circular die, which is then inflated to form a bubble. After the bubble has been formed, the stretch film is cooled, quenched, and wound onto a roll of a stretch wrap.
Blown film extrusion is a versatile process that can be used to create a variety of products, including food packaging, shrink wrap, industrial films, and agricultural films. The process is efficient and cost-effective, making it a popular choice for manufacturers in the stretch film market.
B.Development of Pre-stretch Technology
Pre-stretch technology is a relatively new development that has revolutionized the way materials are handled. This technology applies a stretching force to palletized loads before shipping and unloading. This allows the load to be moved more efficiently and reduces the risk of damage during the handling process in the stretch film market.
Pre-stretch technology has changed the way many businesses handle their materials, allowing them to save time and money by handling their material loads more safely and efficiently. These days, a range of businesses, including the food, beverage, and automotive industries, utilise this technology, which has recently gained popularity.
