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.

The nation highly values the development of private enterprises. As a key force driving economic growth, promoting innovation, and enhancing international competitiveness, private enterprises are seen as a vital force in advancing China's modernization. Recently, authoritative media outlets such as CNR.cn, Xinhua News Agency, People's Daily Online, Reform.cn, Xiamen Daily, Xiamen Radio and Television, and Haixi Morning Post have focused on reporting Changsu Industry's achievements in cultivating the "high-precision" materials sector and contributing to the high-quality development of China's new materials industry.

When you think of aerospace, do you picture cold titanium alloys and sophisticated composite materials? But did you know that a material, hidden in your suitcase, car, and everyday tools, is also quietly playing a crucial role in advanced aircraft? That material is PA6 (Nylon 6), an engineering plastic. Today, let's uncover its "flying secrets"!

Changsu TSA® linear tearing film has a unique structure, and its linear tearing performance allows the microwavable stand up pouch to realize straight tearing without the need for easy tearing lines or other special materials. Even after rapid freezing, high temperature cooking or microwave heating, it will not affect its linear tearing effect.

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.

Changsu Industrial's Vector Film TSA® Instant Tear type, with its "one-second tear" experience, has quickly become the preferred material for leading pet food brands such as Inaba, Sheba, and Kediman.

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.
