PVC/PE composite hard sheet is a hard sheet made of polyvinyl chloride (PVC) and polyethylene (PE) through a composite process. This material combines the high barrier properties of PVC and the heat sealing properties of PE.
PVC/PE composite film is mainly used to make blister packaging in suppository packaging. Since suppositories usually need to maintain a certain shape and stability, the packaging material is required to have good sealing and barrier properties to prevent the drug from getting damp, oxidized or deteriorating. PVC/PE composite film just meets these requirements. Its PVC layer provides good formability and transparency, which is convenient for printing and displaying product information; while the PE layer provides excellent heat sealing performance and flexibility, ensuring the sealing and stability of the packaging.
Performance characteristics of PVC/PE composite hard sheet:
Barrier performance: The PVC layer effectively blocks water vapor, oxygen and light to protect the stability of the contents.
Heat sealing performance: The PE layer is easy to heat seal with various sealing materials to achieve good sealing.
Mechanical strength: The rigid structure ensures that the package is not easily deformed or broken during transportation and storage.
Transparency: Provides clear display and easy observation of the contents.
Safety: The PE layer is non-toxic and odorless, and meets the standards for pharmaceutical and food packaging.

Application areas of PVC/PE composite hard sheets:
Pharmaceutical packaging:
Blister packaging: Commonly used for packaging of solid drugs such as tablets and capsules. With aluminum foil, a complete blister sealing structure can be formed.
Suppository packaging: Provides high barrier properties and mechanical strength to ensure drug quality.
Food packaging: Applicable to candy and snack packaging that requires transparent display. High barrier properties extend the shelf life of food.
Industrial packaging: used for packaging electronic components that need to block oxygen and moisture.
