What is BOPA Film for Lithium Battery Packaging PHA®?
The structural function of BOPA film for lithium battery packaging is as a structural component of the modern energy sector and is an ultra-high-performance PA6 Nylon film specifically for lithium battery aluminium laminated films. BOPA film for lithium battery packaging is developed utilising biaxial orientation technology to create a very strong film mechanically, with high tensile strength. Flexible battery packaging BOPA film is developed to retain structure during the extreme forming and folding processes required to make 3C lithium battery packaging films.
Highly flexible BOPA film for lithium battery packaging has better elongation than most materials; therefore, the material will resist cracking or delamination when the battery shell is deep drawn. The thermal stability of BOPA film for lithium battery packaging has been optimised for commercial applications with a very low shrinkage battery packaging film profile of <2.0%. Therefore, BOPA film for lithium battery packaging remains dimensionally stable at high temperatures throughout the high temperature lamination with aluminium foil and/or other polymer layers. This film has super high puncture resistance as a flexible packaging solution for energy storage batteries to protect against both internal chemical reactions and external physical impacts. BOPA film for lithium battery packaging is manufactured in various thicknesses (15-30 µm) and may be substituted for existing materials to meet International Quality Standards.
BOPA film for lithium battery packaging has been engineered for rapid processing and has a coefficient of friction that minimises the occurrence of manufacturing defects. BOPA film for lithium battery packaging may be treated with either one-sided or two-sided corona treatment to provide excellent adhesion characteristics within multi-layered structures. In addition to being utilised extensively for 3C lithium battery packaging films for mobile phones and wearables, BOPA film for lithium battery packaging may be applied to traction batteries and large-scale energy storage battery flexible packaging. With an annual production capacity of 150,000 tons, BOPA film for lithium battery packaging supplies consistently and competitively a PA6 nylon film for the global new energy markets.

BOPA Film for Lithium Battery Packaging PHA®. Will This Work for my products?
How does BOPA film for lithium battery packaging improve the safety of electronic devices?
The BOPA film provides barrier protection for the internal chemistry of lithium battery packaging film by keeping the battery sealed, and therefore safe, from damage due to mechanical forces such as bending or folding of wearable electronics and/or other physical stresses.
Is this BOPA film suitable for high-speed manufacturing as a battery packaging material for lithium batteries?
Yes, BOPA film (PHA®) has been optimised to provide a unique combination of coefficient of friction to enhance the efficiency of handling and winding, resulting in a lower defect rate in high-speed production lines. As a result of its optimal characteristics, BOPA film is an efficient, flexible battery packaging PHA® BOPA film that can maintain a consistent level of quality throughout the high-speed conversion process of flexible packaging of energy storage batteries for lithium battery applications.
What are the specific properties of our BOPA film that make it well-suited for deep drawing processes?
The excellent flexibility and high elongation of BOPA film (PHA®), for lithium battery packaging, enable the creation of very complex shapes from the PA6 nylon film for lithium battery packaging without cracking. Therefore, these properties are crucial for the formation of the precision shells required in modern 3C lithium battery packaging films.
Is BOPA film PHA® for lithium battery packaging stable after heat laminating?
Absolutely, BOPA film for lithium battery packaging is a low-shrinkage battery packaging film with shrinkage rates of less than 2.0% and is therefore suitable for use in heat-laminated battery packaging film for lithium batteries.
Can BOPA film PHA® for lithium battery packaging be used in large-scale energy storage systems?
Yes, the material is extensively used in energy storage batteries, flexible packaging and traction batteries. BOPA film for lithium battery packaging provides the necessary structural reinforcement and puncture protection required for large-scale cells, meeting global quality standards for the most demanding energy applications.
