BOPET Red Film For Warning Signs

The China BOPET Red Film For Warning Signs produced by Jincheng Manufacturer covers a full range of industrial common thicknesses from 25μm to 100μm. It is suitable for both lightweight decorative laminating and heavy-duty electrical insulation encapsulation in all scenarios.

The entire series is equipped with standardized double-sided differential corona treatment. The inner side has a hardness value of 52-54, ensuring the adhesion of printing, compounding, and gluing. The outer side has a durometer of 42-46, providing smooth anti-adhesion properties. It is suitable for automated high-speed production. It also supports personalized deep processing upgrades, allowing customization of double-sided corona, functional coatings, and anti-static modification treatments. It balances high appearance color display with industrial-level physical protection and electrical insulation performance.

With its eye-catching warning color, stable shading effect, and excellent substrate toughness, it has become the core base material for industrial safety signs, electronic and electrical protection, precision instrument anti-corrosion and dust-proof, and high-end color printing packaging. Combined with a five-level standardized packaging system, it meets the high standards of domestic industrial mass production and cross-border foreign trade delivery requirements.

Factory-specific performance test (EEAT authoritative measured data)

1. Overall color stability test

The factory uses a fully automatic spectrophotometer to conduct color difference detection at multiple points at the head, tail, and middle sections of each roll of film. The R11 and R21 red color series batches are uniform, without color difference or opacity. After undergoing high-temperature baking, repeated friction, and bending weathering tests, the film surface shows no color fading, whitening, powder shedding, or color change. The overall coloring stability far exceeds that of ordinary surface-dyed PET films, meeting the standards for long-term marking and decoration use.

2. Electrical insulation performance simulation test

Carried out for electrical, lithium battery, and circuit board usage scenarios, the measured results show uniform film resistance and stable insulation barrier, without any conductive hazards. Simulating long-term continuous power supply, temperature difference alternating conditions, the insulation performance does not deteriorate, and can stably achieve circuit isolation, static resistance isolation, and adapt to high-risk protection conditions for new energy and precision electronics.

3. Long-term double-sided corona stability test

Batch sampling of the dielectric parameters of BOPET Red Film For Warning Signs was conducted. The values on both sides were strictly locked within the standard range, without fluctuations. After 6 months of storage at room temperature and retesting, the corona value decayed extremely low, still maintaining excellent printing, bonding, and adhesive adhesion, without ink bleeding, delamination, blistering, or other adverse phenomena. The inventory performance is stable, suitable for on-demand stock preparation and mass production.

4. Physical resistance to deformation and fatigue test

Through continuous stretching, repeated bending, and die-cutting durability tests, the film has strong tensile strength and good stiffness. During the processing, it is not prone to stretching deformation, cracking, or edge splitting. Facing frequent equipment processing, material stacking compression, the structural stability is excellent, suitable for industrial large-scale die-cutting, coating, and adhering deep processing production.

5. Customized modification and adaptation test

Carried out for anti-static, special coating, and double-sided corona customization requirements, the on-machine adaptation test was conducted. After modification, the film functions are uniform and the performance is stable, without affecting the original color, insulation, and physical protection characteristics. It can precisely match various high-end and special process industrial and packaging customization requirements.
