Advantages and limitations
Advantages:
Significant anti-counterfeiting effect: disposable, destructively opened.
Exquisite appearance: Enhance product image.
Wide applicability: Suitable for various bottle types and materials.
Low cost: The unit price is very competitive when producing in large quantities.
Automated operation: can be matched with automated filling lines to achieve high-speed production.
Limitations/Precautions:
Environmental issues: PVC materials may cause pressure on the environment during production and disposal processes (containing chlorine, incineration may produce dioxins). This is currently the biggest challenge faced by PVC heat shrink covers, which are gradually being replaced by other environmentally friendly materials.
Temperature resistance: Not resistant to high temperatures. If the contents need to be filled at high temperatures, it is not suitable.
Shrinkage requirement: Additional heat shrink equipment (such as a heat shrink furnace) is required to complete the packaging.
