PP/PE Composite Film Bag

Materials

• PP (Polypropylene): As the outer layer, PP offers high tensile strength, good rigidity, and excellent chemical resistance. It has good transparency, which is beneficial for displaying the packaged products. Additionally, PP has good heat resistance, making the Composite Film suitable for packaging products that may encounter moderate heat during processing or storage.

• PE (Polyethylene): Serving as the inner layer, PE has excellent heat - sealing performance, ensuring a tight and reliable seal when heated. It is flexible and has good impact resistance, providing a soft touch and enhancing the film's ability to withstand external forces. The combination of PP and PE integrates the strength and rigidity of PP with the sealing and flexibility of PE, resulting in a versatile composite film.

Applications

Packaging of Non-sterile Medical Consumables: It is suitable for packaging non-sterile medical items such as medical tape rolls, bandage wrappers, and disposable gloves (for non-surgical use). The PP outer layer provides good rigidity and protection, preventing these items from being crushed during transportation and storage. The PE inner layer ensures a reliable seal, keeping the contents clean by blocking dust and moisture.

Packaging of Medical Accessories: Small medical accessories like syringe plungers, infusion set connectors, and medical cotton swabs (non-sterile) can be packaged with PP/PE Composite Film. Its good transparency allows for easy visual inspection of the accessories, ensuring they are intact before use. The film's mechanical strength protects these small parts from damage.

Secondary Packaging for Medical Devices: For some medical devices that do not require strict sterile packaging but need a protective outer layer, such as certain types of thermometers and blood pressure monitor cuffs, PP/PE composite film serves as an effective secondary packaging. It provides a barrier against external contaminants and helps in organizing and storing the devices neatly.

Packaging of Medical Instruction Materials: Medical instruction booklets, leaflets, and labels accompanying medical products can be packaged using this composite film. The PP layer's printability allows for clear printing of relevant information, while the PE layer's sealing performance keeps the materials dry and free from damage.

Advantages
