Shrink film is a commonly used packaging material with good sealing, waterproof, dustproof, anti-corrosion and other advantages, widely used in food, beverage, daily necessities, electronic products, logistics and transportation and other fields.
The uses of shrink film are mainly divided into two types
Manual packaging is the use of hot air guns or hair dryers on the shrink film to heat the contraction, in order to achieve the purpose of packaging. Manual packaging is simple, convenient and fast, suitable for small quantities or special shapes of product packaging.
The specific steps of manual packaging are as follows
Prepare the shrink film, hot air gun or hair dryer, the product to be packaged.
Spread the shrink film along the length of the product and leave enough margin.
Place the product on the shrink wrap and use your hands to tightly fit the shrink wrap to the product.
Use a heat gun or hair dryer to heat the shrink wrap until it is fully adhered to the product surface.
Use a sealer or lighter to seal the shrink wrap.
Machine packaging is the use of shrink film packaging machine to automatically heat the shrink film to achieve the purpose of packaging. Machine packaging is highly efficient and is suitable for packaging large quantities or standardized products.
The specific steps of machine packaging are as follows
Prepare the shrink film packaging machine, the product to be packaged.
Place the products to be packaged on the conveyor belt of the shrink film packaging machine.
Set the parameters of the shrink film packaging machine, including temperature, speed, sealing mode and so on.
Start the shrink film packaging machine, the shrink film will be automatically heated and contracted, and tightly fit with the product.
After the shrink film packaging machine finishes the operation, take out the packaged products.
