Custom Packaging Roll Film Printed Noodle Bag Packaging Film High-pressure steam at 95 to 121℃
Noodle packaging films require resistance to high-temperature steam sterilization (95-121°C), high barrier properties (moisture and oxygen resistance), excellent heat-sealing performance, and mechanical strength to ensure long-term freshness and compatibility with automated packaging production lines.
The PET/CPE composite material is an ideal choice for high-temperature steam-sterilized noodle packaging due to its outstanding performance.

1. Material Structure: PET/CPE Composite Film
(1) PET Layer (Polyethylene Terephthalate)
- Function: Provides high strength, heat resistance, and high transparency.
- Characteristics:
- Heat Resistance: Melting point ~250°C, can withstand long-term exposure to 121°C steam.
- Mechanical Properties: High tensile strength, resistant to breakage, suitable for high-speed packaging machines.
- Barrier Properties: Excellent oxygen and water vapor barrier, extending noodle shelf life.
(2) CPE Layer (Chlorinated Polyethylene)
- Function: Provides flexibility and heat-sealing performance, ensuring packaging seal integrity.
- Characteristics:
- Heat Sealability: Low-temperature sealing (110-130°C), suitable for automatic packaging machines.
- Chemical Resistance: Resistant to acids and alkalis, prevents noodle oil penetration.
- Flexibility: Improves PET’s brittleness, reducing packaging cracking risk.

2. Applications: High-Temperature Steam Noodle Packaging
- High-Temperature Sterilization (95-121°C): Suitable for instant noodles, udon, ramen, and other noodles requiring steam sterilization.
- Barrier Preservation: Prevents oxidation and moisture absorption, extending shelf life (6-12 months).
- Automated Packaging: Compatible with vertical packaging machines, vacuum sealers, and other high-speed production lines.
