It is understood that the demand for stretch wrap film is increasing sharply every year. With the emergence of various new materials and new equipment technologies, the development of stretch wrap film is moving towards diversification and specialization. So what are the production processes of stretch wrap film? Let stretch wrap film manufacturers explain it to you?
Stretch wrap film is mainly processed with LLDPE as the raw material. It has strong tensile properties, high retractability and self-adhesiveness. Flexible use of stretch wrap film can improve work efficiency. Its production process is as follows:
First: Material suction. Pour the raw materials into a container, then suck them into the casting machine through the machine's pipe. During the process of pouring raw materials, it is necessary to ensure that no other particles or large solids are mixed in, and the raw materials must be clean. This prevents particles from appearing on the surface of the produced stretch wrap film, which would make the product unqualified.
Second step: Casting. The raw materials sucked into the casting machine are processed inside. The temperature must be well controlled, otherwise unqualified products will be produced. Then, after cooling and stretching by the chill roll, the film can be formed. This is a crucial step that determines whether the produced stretch wrap film has characteristics such as strong tensile strength, high retractability and strong puncture resistance.
Third step: Mother roll. Wind up the stretched wrap film to form a large mother roll.
Fourth step: Rewinding. This is mainly done according to customer requirements.
Fifth step: Determine the size of the carton according to the customer's required quantity and the size of the products. Remember to handle with care during the packaging process to prevent the head of the stretch wrap film from being damaged by impact, which would cause it to break when pulled during use.
