What is ULTRANY® CHA® BOPA Film for Functional Coating?
ULTRANY® CHA® is a speciality coating-grade BOPA film produced via the Lisim linear-simultaneous-stretching technology for functional coating applications. This coating-grade BOPA film is designed for high-performance applications requiring high-quality flatness and good isotropic performance. Due to the use of the Lisim process, this oxygen barrier-coating-substrate exhibits a very smooth and even surface, which is necessary for producing high-quality, thin, and defect-free functional layers. The heat-resistant BOPA film for lamination has a wide temperature range and a low heat-shrinkage of <1.8% (MD) at 160°C and thus provides a stable dimensionality during high-intensity drying and retort processes.
The smooth and flat BOPA film can serve as a perfect carrier for barrier coatings such as PVDC or alumina, as well as for special anti-fog or UV-barrier-treatments. The PA6 coating-base film has a tensile strength of 220/250 N/mm² (MD/TD) and 10N puncture resistance and therefore provides a robust mechanical protection for complex composite structures. The coating-grade BOPA film additionally increases the retail attractiveness by providing excellent optical properties with a high gloss and a haze value of 4.0%. In addition, the oxygen-transmission-rate of 50 cc/(·day·atm) of the oxygen barrier-coating-substrate guarantees a long-lasting preservation of the content.
Example Case Study: Improving Coating Speed and Precision:
A major producer of flexible printed circuit boards (FPCs) experienced problems with surface defects and warping in the past with conventional nylon substrates for insulating coatings. After replacing these with ULTRANY® CHA® coating-grade BOPA film, the customer profited from the improved flatness and isotropy due to Lisim technology. The flat and smooth BOPA film enabled a 15% increase in coating-line speed, while simultaneously reducing the amount of defective film due to warping by 20%. This improvement in reliability led to a substantial rise in the level of customer satisfaction, which contributed to a strong increase in orders for high-precision electronic components and ultimately to a significant growth in quarterly sales for the client.

Will ULTRANY® CHA® BOPA Film for Functional Coating Work for My Application?
Why is ULTRANY® CHA® a better coating-grade BOPA film?
ULTRANY® CHA® uses Lisim simultaneous stretching technology, which produces a flat and smooth BOPA film with excellent isotropy and, hence, ensures a stable and uniform film during high-speed coating, avoiding defects caused by uneven surfaces of standard nylon substrates.
How does this film function as an oxygen barrier coating substrate?
Although the basic PA6 coating-base film has a transmission rate of 50 cc/(·day·atm), the smooth surface of the film provides an optimal basis for secondary barrier coatings. Thus, the coating-grade BOPA film is a perfect carrier for Alumina or PVDC layers to generate ultra-high barrier packaging.
Is this film suitable as a heat-resistant BOPA film for lamination?
Yes, certainly. ULTRANY® CHA® is designed for high-heat environments with a heat shrinkage of <1.8% at 160°C and, therefore, is a highly reliable heat-resistant BOPA film for lamination in retort packaging or in high-temperature processes involving heat-sealable coatings.
Can this film be used for generating sufficient transparency for luxury packaging?
Yes, the film exhibits excellent transparency and high gloss with a low haze of 4.0%, enabling a high-quality appearance of luxury cosmetics and skincare products.
What is the puncture resistance of this PA6 coating-base film?
ULTRANY® CHA® coating-grade BOPA film possesses a puncture resistance of 10N. In combination with high tensile strength, this ensures that the heat-resistant BOPA film for lamination remains durable throughout processing and end use.
What is the production capacity of this coating-grade BOPA film?
Xiamen Changsu has a huge global production capacity of 150,000 tons per year and is still expanding. Therefore, we can provide a stable and reliable supply of PA6 coating-based film and oxygen barrier-coating-substrate-materials for the large-scale industrial and packaging customers.
