How weather resistant is BOPP synthetic label paper?

The weather resistance of BOPP (biaxially stretched polypropylene film) synthetic label paper is relatively good, mainly due to its material characteristics and production process. The following is a detailed analysis of the weather resistance of BOPP synthetic label paper:

1. Material characteristics

High strength and wear resistance: BOPP film is made by two-way drawing process, with high tensile strength and wear resistance, which makes BOPP label paper in the external environmental factors (such as wind and sun, friction, etc.), can maintain good physical properties, not easy to break.

Waterproof and oil-proof: BOPP film itself has the characteristics of waterproof and oil-proof, which is particularly important in the application of label paper, which can protect the printed content on the label from liquid erosion, thereby extending the service life of the label.

Aging resistance: BOPP material after special treatment, such as the addition of anti-aging agents, can significantly improve its aging resistance, so that the label paper can still maintain a good appearance and performance in the outdoor environment for a long time.

2. Production process

Bidirectional drawing process: Through the bidirectional drawing process, the molecular chains of the BOPP film are rearranged to form a more compact crystalline structure, thereby improving the mechanical properties and thermal stability of the film. This structural optimization makes BOPP label paper excellent in weather resistance.

Surface treatment: In order to improve the printing adaptability and adhesion of BOPP film, corona treatment is usually performed on its surface. This treatment not only helps to attach the ink, but also enhances the surface hardness and weather resistance of the film to a certain extent.

3. Application field and performance

Widely used: BOPP synthetic label paper is widely used in the packaging of shampoo, shower gel, daily chemical laundry detergent, cosmetics, skin care products and other products. These products often need to go through multiple links such as transportation, storage and sales, and BOPP label paper can maintain good appearance and performance in these links with its excellent weather resistance.

Actual performance: In practical applications, BOPP label paper can withstand the test of a variety of external environmental factors such as temperature changes, humidity fluctuations, ultraviolet radiation, and is not easy to fade, deform or fall off, thus ensuring the accurate transmission of product information and the integrity of the packaging.

In summary, BOPP synthetic label paper has excellent performance in weather resistance and can meet the needs of use in various harsh environments. However, it is worth noting that although BOPP label paper has good weather resistance, it still needs to be used carefully under extreme conditions (such as extremely high temperature, extremely low temperature or strong ultraviolet irradiation, etc.) to avoid label damage caused by limited material properties.
