Shrink film, also known as shrink wrap or heat shrink film, is a versatile packaging material used in various industries to protect and secure products during storage and transportation. It is made of polymer plastic that shrinks tightly to the object it covers when heated. This creates a secure and professional-looking package. One of the best sources for obtaining shrink film is packaging film factories.
In a packaging film factory, the manufacturing process of shrink film involves multiple steps. Here is an overview of how the shrink film of the packaging film factory is made. Next, we will briefly discuss how the price of heat shrink packaging film sold directly by the manufacturer is set.
The first step in the manufacturing process is to create a polymer mixture. The most common type of plastic used to make shrink film is polyolefin, a polymer that can stretch and shrink easily. The raw materials are fed into a hopper, where they are melted and mixed with other additives to give the film the desired properties, such as UV resistance, puncture resistance or transparency.
After the polymer mixture is prepared, it is fed into an extruder, which heats and shapes the polymer into a thin, continuous sheet. The sheet can be stretched or oriented in various ways to enhance its strength and flexibility. After this, the film is cooled and rolled onto large spools, ready for further processing.
The next step in the manufacturing process is to print the film. If the shrink film is to be printed with a logo, product information, or other graphics, it will pass through a printing press before being rolled onto a smaller roll. This step requires precision and attention to detail to ensure accurate and consistent printing on every roll of film.
After printing, the film is subjected to a corona discharge treatment to improve its adhesion. This step is crucial as it helps the film adhere better to the product as it heats and shrinks. After processing, the film is cut to the required width and length, then packaged and sent to customers.
When it comes to direct-to-factory shrink wrap film, several factors come into play. The cost of manufacturing raw materials, labor, and overhead all affect the final price of shrink film. In addition, film size, thickness and printing requirements also affect cost.
Customers can save money by purchasing shrink film directly from packaging film factories at ex-factory prices. By bypassing distributors and dealers, customers can take advantage of wholesale pricing and potentially negotiate a better deal based on their specific needs and volume requirements.
In summary, shrink film is an important packaging material used in various industries. The manufacturing process in a packaging film plant involves multiple steps, including creating a polymer blend, extruding the film, printing, processing, cutting and packaging. Factory direct sales of heat shrink packaging film are affected by many factors, but customers can save money by purchasing directly from the manufacturer. This helps them get high-quality shrink films at competitive prices.
