I look at our industry from a different angle today as we celebrate International Women’s Day. The term "barriers" and "strength" of high-performance films mean something different to me as a female leader in this space — protection and the ability to safeguard what matters most and allow it to flourish.

The performance of ultra-high barrier BOPA film under high temperatures is not just about surviving the heat—it is about delivering consistent, reliable protection throughout the product's lifecycle. By leveraging the natural thermal resistance of polyamide and enhancing it with sophisticated barrier technologies, modern BOPA film ensures that even the most sensitive foods can be safely sterilized and stored for months, without compromising quality or safety.

In daily life, unscientific food preservation methods not only cause waste and pollution but can even harm health. Food rots because components in the air, such as oxygen or microorganisms like bacteria, react chemically with certain components in the food. Extending the shelf life of food means slowing down the rate of this chemical reaction as much as possible. We can use many methods, such as temperature control, modified atmosphere packaging, sterilization, and vacuum sealing.

Food spoilage is primarily caused by oxidation and microorganisms, traditionally relying on chemical additives for inhibition. Now, physical preservation technology is changing the game. Taking Changpu EHA freshness-locking film as an example, it possesses ultra-high oxygen barrier properties (oxygen permeability <2cc/(m²·day·atm)), significantly delaying food oxidation and maximizing the preservation of freshness.

Changsu BOPA film is safe, non-toxic, and environmentally friendly, with superior overall performance. It is widely used in food, daily chemicals, pharmaceuticals, new energy vehicles and other fields, making it a leading film material for the future.

BOPA boasts excellent tensile and puncture resistance, easily withstanding various long-distance, high-load, and harsh environmental transportation and storage processes. It is not prone to brittleness and breakage even at -60℃, thus preventing shortened shelf life or spoilage and waste, greatly expanding the application range and scenarios for frozen foods.
