Stretch Film is a kind of packaging material in the logistics industry, which has been widely used in the logistics industry. It can reduce labor force, moisture-proof, dust-proof, improve efficiency, achieve the purpose of product protection, reduce the cost of collective packaging of products or goods. There are many materials for stretch film production, which mainly depend on the application field of products. Therefore, to control the viscosity of stretch film, you can control the viscosity of stretch film in materials Work hard on materials.
Not all c4-lldpe can be matched. C6 and C8 materials are often used because they are easy to process, and the temperature also affects the viscosity of the stretch film. Generally, we will put the product in the environment of 15-25 degrees. If the temperature is more than 30 degrees, the viscosity will increase; if it is less than 15 degrees, the viscosity will change.
As there will be polyethylene component in the tensile film, we can adjust the amount of adhesive layer polyethylene to achieve the required viscosity; because the molecular weight distribution of the tensile film is narrow, and the processing range is narrow, generally as long as 5% polyethylene is added, the effect of reducing the melt viscosity can be achieved, so the flatness of the tensile film will also be improved and the film will be increased The flatness of.
Various cost factors for the production of stretch film include: raw materials account for 80%; equipment account for 7%; paper core and other auxiliary materials account for 4%; energy consumption accounts for 5%; labor, waste, experiment and marketing account for 4%. It can be seen that raw materials become the primary factor affecting the consumption cost of stretch wound film. Therefore, reducing the amount of raw materials and improving the process formula become the main method to reduce the cost of stretch winding film. Although only 6% of the factors affect the consumption equipment of stretch film, its reliability and quality are also very important factors.
Any loss of raw materials due to poor consumption linearity and equipment failure will immediately have a great direct negative impact on the profitability of the whole project. Considering that even if 10% more equipment investment is added to choose better equipment, the cost ratio will only increase from 6% to 6.6%.
