Shrink Wrapping is a process that involves the wrapping of temperature sensitive films around an item or product. After the item is wrapped it will typically go through a heat tunnel to shrink the film down and tightly conform to your product.
For applications that are larger in scale, shrink wrapping machines are required to shrink wrap products into bundles, or put a protective barrier over them to protect from dust, moisture, air, or other contaminants.
At Korpack, our shrink wrapping machines range from simple semi-automatic versions that can produce 15-20 packages per minute up to highly automated systems that can wrap up to 180 packages a minute. Our machines are commonly used in the food industry for seafood, poultry, dairy, cheese, produce, frozen pizzas and other RTE (ready to eat) products. Printers and third-party fulfillment operations also use our shrink wrapping equipment to bundle brochures or other literature.
We have partnered with Shanklin™ Shrink Wrapping machines to bring you a cost-effective and efficient solution for your shrink wrapping needs.
The term “shrink wrap machine” gets tossed around a lot in the packaging industry. A shrink wrap machine refers to a machine that uses heat shrink packaging, including both a sealer and a heat source that applies heat. The heat is used to shrink the film wrap, which will contract when properly heated.
Shrink wrap machines utilize shrink film. A product can be placed inside of the film. Next the shrink wrap machine will close each end of the shrink wrap film. Then heat is applied and the wrap quite literally shrinks (hence the name).
Some shrink wrap machines are fully automated and heat will be applied automatically. For smaller, low-volume operations, using a heat gun may be more practical. There are many different types of shrink wrap machines. Let’s look at a few.
L-Bar Sealers- These shrink wrapping machines feature three sealing bars and can efficiently and easily seal centerfold shrink wrap. These shrink wrap sealers are often operated manually and perform better in low volume settings.
Auto L-Bar Shrink Wrapper- Don’t want to handle your shrink wrapping manually? You can use an auto L Bar Shrink Wrapper to handle it all automatically. An Auto L-Bar Shrink Wrapper works in a similar fashion as a manual machine but most of the work is automated. This allows for higher speeds and excellent accuracy.
I-Bar Sealers- These shrink wrap sealers use only one bar to cut and seal the shrink wrap in a single motion. Portable I-Bar machines are also available. This way, you don’t have to move products but can instead move your shrink wrapper to the products.
Impulse Foot Sealers- These sealers are operated with your feet, freeing your hands up to place the products in the sealer. Next, simply use your feet to engage the sealer. If you’re using bags, you can use a round wire foot sealer to seal and cut bags with one motion.
Shrink Tunnels- Uses a conveyor belt that runs through a heated tunnel. This ensures that heat will be optimally applied and that the film will fit tightly. The end result is a consistent seal.
There are other types of shrink wrapping machines. Further, once you determine the type of shrink wrap machine you need, you'll have to chose what specific model. Need assistance?
