BOPET Milk White Film for Luxury Packaging

Compared with ordinary coating color films, the BOPET Milk White Film For Luxury Packing produced by the Jincheng manufacturer is formed through the overall color adjustment of the substrate. The film has uniform and pure color, without any impurities or transparent spots, presenting a delicate and transparent high-end milky white texture. There are no problems such as coating detachment, uneven color, or surface blemishes.

Product Core Advantages

1. Native overall coloring, with high-quality texture and no flaws

2. High gloss diffusion performance, with stable and outstanding light distribution effect

3. Double-sided functional corona, with extremely strong adaptability for further processing

4. One film for multiple uses, covering packaging, optics, and decoration sectors

5. Stable base material performance, resistant to weathering, durable, and not prone to deformation

It has high opacity and excellent light diffusion properties. The surface presents a uniform and fine milky white appearance. It can soften point light into a uniform and soft surface light source, and has a high light transmittance.

Product thickness: 15μm, 25μm, 45μm, 50μm, 75μm, 100μm

Professional performance testing (factory factory test)

1. Optical uniformity performance test

The factory uses professional optical testing equipment to conduct comprehensive tests on each batch of BOPET Milk White Film for Luxury Packaging, including haze, transmittance, and uniformity. The measured film haze is uniform and stable, the transmittance meets the standard, and there are no local differences in transmittance. When tested with a light source, there are no bright spots, no dark areas, no light focusing problems, and the point light source diffuses evenly, fully meeting the high-precision optical usage standards for LCD backlight modules, advertising light boxes, and lighting panels.

2. Color uniformity consistency test

Through global scanning with an automatic color difference meter, the color at the head, tail, and middle of the entire roll of film shows no deviation. The film is uniformly white and has no color difference. After friction and bending resistance color tests, the film surface shows no color fading, no whitening, and no through-color phenomenon. The overall coloring stability is far superior to those of later spraying and coating color-changing films, ensuring the visual uniformity of high-end packaging products in large batches.

3. Stability test of double-sided corona value

A multi-point sampling testing mechanism is implemented to strictly control the range of double-sided dynes, eliminating problems of parameter over-limitation or under-limitation. After long-term constant-temperature storage and static simulation tests, the corona value attenuation is extremely low. After storage for several months, it still maintains excellent printing, bonding adhesion, and no ink fading, delamination, or other problems. The batch production control is stable.

4. Physical weathering stability test

Simulate the regular processing, storage, and usage environment to conduct tests on bending resistance, tensile strength, and aging resistance. The film repeatedly bends without cracking or deformation, and there is no damage during stretching. Long-term storage shows no yellowing, dullness, aging failure, etc. It is suitable for packaging deep processing, indoor decoration, and long-term use in optical equipment.

5. Printing and painting adaptability test

Carry out on-machine tests for advertising printing and color printing packaging processes. The film surface absorbs ink evenly, and the color reproduction is high. The printed picture is bright and transparent, without ink smearing, color fading, blurriness, or double shadows. After laminating and adhering, it is flat without blisters or edge curling, perfectly adapting to the large-scale production requirements of high-end color printing and advertising printing.

The inner corona surface has a resistance of 52-54 dynes, while the non-corona surface has a resistance of 42-46 dynes.
