Winding film is also called PE film. In this era of rapid development of logistics industry, as a new type of packaging material, winding film plays a very important role in the transportation of products. Therefore, winding film has become a leader in packaging materials. What is the packaging effect of winding film?
The winding film is strong and tough, has high impact resistance and penetration strength, good self-adhesive, transparent, does not expand the volume of goods after packaging, can be shockproof, moisture-proof and strong protection. It is a very popular packaging form in the world. Winding film is widely used for wrapping food, tobacco, medicine and other products. There are many kinds of winding films with different functions. Flexible packaging is used for all or part wrapping. The packaging equipment of products is collectively referred to as wrapping. PE tensile film is one of the most important parts in the packaging industry.
The use of winding film for packaging can greatly reduce the production cost of the enterprise, reduce the labor intensity of workers, improve the packaging efficiency and packaging grade. The manual winding film only needs a hand-held unwinding rack with damping brake, and one person holds the surrounding package, which is light and flexible. According to local conditions, the machine winding film is suitable for the packaging of batches of goods, If it is used with the winding machine, it will greatly improve the production efficiency, make the packaging uniform and beautiful, good packaging quality and fast speed.
The winding film does not need heat shrinkage treatment in the packaging process, which is conducive to saving energy, reducing packaging cost, facilitating container transportation and improving logistics efficiency. The "integrated loading and unloading" method combined with pallet and forklift reduces the transportation cost. At the same time, it is also easy to identify the wrapped items with high transparency and reduce distribution errors. Production process conditions due to the long and narrow flow channel and fast flow speed, the melt temperature range is generally controlled at 250 ℃ ~ 280 ℃, the temperature of the casting cooling roll is controlled at 20 ℃ ~ 30 ℃, and the winding tension is generally less than 10kg, so as to facilitate the migration of the adhesive and reduce the internal stress of the finished film.
The winding film has the advantages of toughness, impact resistance, transparency and self-adhesive. Whether it is used for collective packaging of products or cargo card board, it can prevent moisture, dust, reduce labor, improve benefits, and achieve the purpose of protecting products and reducing costs.
