Shrink wrap and cellophane wrap are two very common box wrapping methods. But what is the difference between shrink wrap and cellophane?
1. Shrink wrap
Working principle: When the heat shrinkable film is heated at high temperature, the irregular arrangement of atoms changes drastically. Under the use of infrared radiation, plastic molecules move again, the arrangement changes, so as to achieve the re-arrangement of atoms by heating to reduce the area of the packaging film. This can more closely fit the product to be packaged, and can quickly wrap the product with a layer of film.
Tool: The wrapping process is completed by a shrink wrapping machine
- Adopting advanced film constant temperature heat sealing technology, the sealing is clear and firm.
- The rapid cooling structure of the sealing ensures higher sealing strength under high-speed production conditions.
- It adopts PLC program automatic cycle control, stable and reliable performance.
- Unique heat shrinkage channel, two sets of centrifugal hot air circulation system, uniform heat balance, tight shrinkage and beautiful appearance.
- Three-layer heat insulation treatment, good heat preservation performance, fast heating, and energy saving.
2. Cellophane wrap
Working principle: The packaging film is cut into the required length by a cutter, the box is transported to the predetermined position through the conveyor, then wrap and fold to form a well-designed packaging style.
Tool: Complete the wrapping process by the cellophane wrapping machine.
- Instant sealing, similar to cold packaging, will not affect heat-sensitive products such as medicines.
- Fully automated operation process, automatic feeding, stacking, packaging, heat sealing, sorting and counting, high production efficiency, reducing the labor cost of the enterprise.
- PLC man-machine interface control system ensures stable and reliable performance of machine equipment and more stable operation.
- Humanized and intelligent design and operating system make operation and maintenance easier.
In addition, the packaging range of shrink wrap is wider; the packaging effect of cellophane wrap is more beautiful. One set of shrink wrap machine can be used for different boxes sizes, one set of cellophane wrap machine can only wrap one box size.
