What is hard PVC?

PVC hard film/sheet/panel Hard PVC (polyvinyl chloride) is a high-strength, stiff, low-cost plastic material widely used in advertising materials such as printing and product packaging. It is easy to manufacture and easy to use adhesives or adhesive bonding solvents. PVC is also easy to weld using thermoplastic welding equipment. PVC film - also a thin thermoplastic film, comes in a variety of forms and finishes.

PVC pharmaceutical film is easy to heat seal, printable, chemical-resistant, easy to process, printable, and chemical-resistant. Widely used in granular tablet packaging and small-dose liquid packaging, PVC rigid sheet is safe, hygienic, and low-cost.

Application:

Pharmaceutical grade PVC film rigid sheet is widely used in aluminum-plastic blister packaging of medicines, such as tablets, capsules, oral liquids, suppositories, pills, etc. It can protect the medicine from the erosion of the external environment, thereby extending its shelf life and stability.

Production process:

The production of PVC rigid sheets for pharmaceutical packaging usually involves calendering or blow molding, of which calendering is more common. During the production process, process parameters such as melting temperature, mold temperature, injection pressure, etc. need to be strictly controlled to ensure product quality.
