The winding film has been widely used in the Prevalent industry. Now there are many manufacturers of all sizes in the market. Many manufacturers have made many quality changes to the winding film in order to save costs, resulting in many inferior winding films in the market. So how to reduce the production cost of the stretch winding film?
Various cost factors for production of winding film include: raw material accounts for 80%; Equipment accounts for 7%; Paper core and other auxiliary materials account for 4%; 5% of the energy consumption (explanation: materials that provide energy conversion to nature); Labor, waste, experiment and marketing account for 4%. In the early stage of winding film wholesale, LLDPE winding film was mainly blown film, which developed from single layer to two or three layers; LLDPE winding film is mainly produced by tape casting. It can be seen that raw material has become the primary factor affecting the cost of stretch winding film. Therefore, reducing the amount of raw materials and improving the process formula become the main method to reduce the packaging cost of stretch winding film.
Reduce the thickness of winding film
Because the winding film is widely used in the integrated packaging of hardware, minerals, chemicals, medicine, food, machinery and other products; In the field of warehouse storage, foreign countries also use stretch wrapped film tray packaging for three-dimensional storage and transportation to save space and land. The self-adhesion of the winding film makes the packaging film and layer on the outside of the goods stick together to make the goods firm. The application of the winding film is becoming more and more extensive. From 1975 to 2013, the uniformity of the tensile winding film (j ū N y ú n) The thickness once changed from 30 μ M reduce to 20 μ m. However, the elongation increased from 50% to 300%. At present, the thickness of Zhengdexiang Company can reach 8um. The thinner the thickness, the longer the length of a coil of winding film under the same weight, the more goods will be packed. The reduced thickness can reduce the packaging cost by more than 30% - 50%
