PET based heat sealing film is a high-performance sealing material specially designed for freeze-dried food (such as fruits, vegetables, meat, instant Congee, etc.) packaging containers. It adopts multi-layer co extrusion technology, using high-quality polyethylene terephthalate (PET) as the substrate, and is precisely laminated and compounded with a heat sealing layer.

This design combines the excellent mechanical strength, high transparency, and low-temperature sealing performance of PET with the excellent heat sealing layer, providing a perfect packaging solution for freeze-dried food that is high barrier, strong sealed, and easy to open, effectively extending product shelf life and ensuring food safety and quality.

• Ultimate freshness locking and excellent barrier properties: The film has extremely high water vapor barrier properties and good oxygen barrier properties, which can effectively prevent external water vapor and oxygen from entering, ensuring that freeze-dried food maintains a crispy taste and original nutrition for a long time, and preventing moisture and spoilage.
• Sealed firmly and with low bag breakage rate: Excellent heat sealing strength enables it to form a firm and uniform sealing edge with various common plastic containers such as PP, PS, PET cups/bowls. The sealed area has good impact and tear resistance, effectively reducing the risk of bag breakage during transportation and handling.
• Convenient opening and upgraded experience: Through precise process control, the product can achieve various controllable opening forces from "easy to open" to "fully open" while ensuring a firm seal, bringing users a smooth and comfortable opening experience.
• High transparency and strong display: The highly transparent PET substrate can perfectly present the color and shape of the freeze-dried food inside, and the excellent quality of the product can be intuitively felt without unpacking.
• Wide process adaptability: This film is compatible with mainstream high-speed automatic filling and hot sealing equipment, with a wide hot sealing window and high process tolerance, which can effectively improve production line efficiency.

• Freeze dried fruit/vegetable chunks: such as freeze-dried strawberries, mangoes, apples, mushrooms, corn kernels, etc.
• Freeze dried instant soup/Congee: instant food after rehydration.
• Freeze dried coffee/dairy products: products that require extreme moisture resistance to maintain flavor.
• Pet freeze-dried food: providing a reliable preservation solution for high-end pet nutrition food.
• Freeze dried rations specifically designed for aerospace and outdoor exploration: meeting the long-term storage needs in extreme environments.
