Stretch film in questions and answers ...
The answer to this question is contained in the question "Why does the stretch film stick to"
Stretch film is the common name of polyethylene film. It is a packaging material that is almost 100% made of a raw material called linear low-density polyethylene - LLDPE. The most important features of the stretch film are flexibility, thermoplasticity, waxiness and transparency.
Shrink film is very often confused with stretch film , but it is a completely different type of material. Shrink wrapping occurs when shrink wrap/plastic is loosely applied, placed around an object, and then - with the help of a source of hot air, for example from a heater - it begins to shrink and adhere tightly to the object on which it has been applied.
Stretch film is sticky thanks to its properties that are created during the production of stretch film by blow molding. In the production process of stretch film by blow molding, there is no use of glue or any other substance acting in a similar way. The stretch film adheres very well to all types of matter, which is due to the texture of the film and its features such as: thickness, flexibility and strength, which translates into a very precise fit to the most unusual shapes
Stretch film is commonly used in households as well as in various companies. In households, we can use it for practically everything. When it comes to companies, we can especially point out production companies, forwarding companies and generally dealing with logistics and transport of goods.
Depending on the selected roll weight, the foil may be, for example, 100 m or even 300 m long , depending on its thickness. Not every roll of stretch film weighs the same and is largely affected by the weight of the sleeve itself, its thickness, which in turn translates into the length of the stretch film wound on the sleeve. Therefore, it is worth not to be guided by the weight itself and pay special attention to the number of meters. The offer includes films with popular weights of 1.5 kg, 2.0 kg, 2.5 kg and 3 kg. Nevertheless, as a producer, we are able to produce any type of foil.
