Stretch film has been widely used in the logistics industry. Nowadays, large and small manufacturers appear on the market. Many manufacturers have made many quality changes to stretch films in order to save costs, resulting in many poor quality stretch films on the market Film, so how to reduce the production cost of stretch film? Stretch film manufacturers


First, reduce the thickness of the stretched film

From 1975 to 2013, the uniform thickness of the stretch-wound film was reduced from 30 μm to 20 μm, while the stretch rate was increased from 50% to 300%. This is due to the development of new materials, such as metallocene materials, which provide higher tensile strength and elongation.


Twenty-two, using new raw materials and process formulas

Recently, raw material suppliers have provided another opportunity for stretch film manufacturers. This is the source material of the slip layer and the adhesive layer with the same brand as the core layer, but a small proportion of the additive masterbatch (usually 15% to 35% of the layer) is involved in the adhesive layer. Similarly, a certain proportion of additive masterbatch is also used in the slip layer (up to 55% of the layer). At this time, the same large material station can be used to stop the storage and optimization of the main raw material, and the additive masterbatch can be directly stored in the original small packaging bag.


Of course, the impact factor of stretch film consumer equipment only accounts for 6%, but its reliability and quality are also very important factors. Any loss of raw materials due to poor performance of the consumer line and equipment defects will immediately have a great direct negative impact on the rate of return of the entire project. And thinking that even if the investment in equipment is increased by 10% to choose better equipment, the cost ratio has only increased from 6% to 6.6%.


How to reduce the production cost of stretched stretch film is shared here. Choosing a more reliable and higher quality consumption line is also a key factor to reduce the consumption cost of stretched film.
