HEAT AND PRESSURE RESISTANCE OF PA/PE 2-LAYER FILM

The PA/PE two-layer film is a multilayer packaging film made from Polyamide (PA) and Polyethylene (PE). This is one of the popular choices for applications requiring heat and pressure resistance.

Heat Resistance:

• Polyamide (PA), also known as Nylon, is a type of plastic with good heat resistance. PA can typically withstand temperatures ranging from about 120°C to 150°C, depending on the specific type of PA.

• Polyethylene (PE) also has relatively good heat resistance, typically able to withstand temperatures up to around 80-100°C.

Pressure Resistance:

• Polyethylene (PE) is a flexible plastic with good ductility, allowing it to withstand internal pressure without cracking or tearing.

• When used as a cover layer in multilayer packaging film, PE often provides good pressure resistance, helping the packaging film protect the product from external intrusion.

With its PA/PE two-layer structure, this film can offer sufficient heat and pressure resistance to meet the needs of many applications, including food packaging under high temperature and pressure conditions, such as in retort processes for sterilizing and preserving products. However, using this film also requires adhering to specific technical requirements and food safety standards to ensure the quality of the packaged product.
