The shrink wrap tunnel machine wraps the PE film of the books by heating, which fully displays the appearance of the book, improves the product’s salesability, and increases the appearance and value. The small shrink wrap machine has a good sealing effect on the product, which can effectively prevent the product from being interfered by external factors.
Shrink Wrap Tunnel Machine Principle:
The hot air generated by the electric heating tube rotates at a high speed through the two large impellers inside, so that the hot air becomes uniform. Then, the hot air rotating at a high speed is ejected from each hole of the inner liner of the machine, and the items passing through the furnace are quickly and comprehensively shrink.
Features of Shrink Wrap Machine for Books:
- The machine has the fully automated functions of conveying and feeding, film wrapping, sealing and cutting, shrinking, cooling and shaping.
- The sensor switch controls the film feeding system, which can reliably regulate the film feeding length and reduce the loss.
- The shrink tunnel wrap machine using advanced film constant temperature heat sealing technology, the sealing is clear and firm.
- The rapid cooling structure of the sealing ensures that the sealing strength is higher under high-speed production conditions.
- A high-power wind-driven motor is used to ensure that the wind is strong enough to achieve the packaging effect at one time.
- The book shrink wrap machine has two sets of centrifugal hot air circulation system, the heat balance is even, the contraction is tight and beautiful.
- Three-layer thermal insulation treatment, good thermal insulation performance, rapid temperature rise, energy saving.
