BOPET Milk White Film For Advertising Substrate

The BOPET Milk White Film for Advertising Substrate manufactured by Jincheng suppliers is produced using the original color masterbatch integrated melt extrusion process. It does not have surface coating. The film body has a uniform and fine white texture without particles, no light transmission spots, and no local color differences. This ensures the stable and uniform output of the advertising image from the base material level.

The product is equipped with a full range of thicknesses from 15μm to 100μm, suitable for the advertising industry. It can cover all scenarios including ultra-thin indoor light boxes, regular storefront advertisements, large outdoor light boxes, and high-definition printed images.

Standardized double-sided differentiated corona treatment, with bonding surface reaching 52-54 dynes, significantly enhancing the adhesion of ink, glue, and composite layer, preventing color fading, peeling, and delamination of the advertisement image; the outer surface reaches 42-46 dynes, with a smooth and flat film surface that is resistant to stains and easy to clean.

Product Usage Instructions (Exclusive for the Advertising Industry)

1. Pre-treatment of the substrate for compatibility with printing processes

Before printing on the machine, keep the film surface dry and clean, free of dust, oil stains, and moisture. No need for secondary corona activation. It can directly be adapted to mainstream advertising processes such as digital printing, UV printing, and screen printing. The film material has stable factory tension, and the material runs smoothly without deviation, suitable for high-speed advertising printing production equipment.

2. Assembly and Adhesion Specifications for Backlit Billboard Advertisements

When used as a base material for backlit billboards, the film material should be laid flat, maintaining uniform tension, and avoiding excessive stretching that may cause later relaxation and deformation; during installation, keep the environment dust-free to prevent impurities from being mixed in, causing the picture to protrude or bubbles, and ensure the smoothness and transparency of the advertisement board surface.

3. Usage for Multi-Site Advertising Scenarios

Lightweight specifications are suitable for indoor small billboards, poster printing, and store display boards; medium-thick specifications are suitable for store signs and indoor advertising billboards; thickened high-stiffness specifications are suitable for outdoor large advertising boards and ultra-large-sized billboard pictures, with better resistance to deformation and higher flatness.

4. Operation of Composite Mounting and Painting Process

When using for mounting film on advertising pictures or composite of boards, utilize high-adhesion corona surface for bonding, with a wide temperature range for heat pressing, no need for precise parameter adjustment, and after bonding, the edges are flat, without wrinkles, and no glue detachment, significantly improving the yield rate of advertising products.

Professional Maintenance and Care Guidelines

1. Daily Cleaning and Maintenance

Regularly use ultra-fine fiber soft cloths to wipe and remove dust. For stubborn stains, use neutral diluted cleaning agents for gentle wiping. Alcohol, acetone, and strong acid-base solvents must not be used for wiping to prevent corrosion of the film surface, damage to the printed color and surface texture, and to effectively extend the display period of the advertising image.

2. Storage in Environment and Idle Maintenance

Unused rolls should be stored upright in a dry, ventilated, light-shielded, and temperature-controlled warehouse. Heavy pressure stacking and damp, sealed storage are prohibited to prevent the film surface from getting damp and sticking, tension loss, and color variation. This ensures consistent subsequent printing results.

3. Regular Inspection of Floor Advertising Products

Indoor advertisements should be cleaned and inspected once every quarter, while outdoor advertisements should be inspected monthly. Key issues such as film surface warping, relaxation, accumulation of stains, and local color changes should be thoroughly checked. After rainy or windy weather, promptly remove accumulated water and dust to prevent long-term erosion and aging.

4. Avoiding Damage from Extreme Conditions

Outdoor advertising installations should avoid long-term exposure to direct sunlight and heavy rain. In low-temperature environments, it is prohibited to forcibly stretch the film material to prevent cracking and deformation. Minor wrinkles can be naturally smoothed at room temperature, and violent high-temperature baking for repair is prohibited.

5. Orderly Management of Batch Inventory

Follow the principle of "first in, first out". Regularly check the stored rolls for long-term storage. Ensure that the performance of each batch of advertising substrates is stable and the printing results are consistent. Avoid aging of the inventory that leads to color differences and adhesion decline in the images.
