ПВДХ (сополимер поливинилхлорида/поливинилацетата) покрытие обычно используется при приготовлении фармацевтической алюминиевой фольги для обеспечения лучших барьерных и защитных свойств.. The following is the composite process of general ПВДХ coating and pharmaceutical aluminum foil:

Prepare the medicinal foil: Общая спецификация, the medicinal foil is cut or trimmed to the required size with the appropriate width and length.

Coated PVDC: During the lamination process, a PVDC coating is applied on one side of the pharmaceutical grade aluminum foil. PVDC coatings can be applied by a variety of methods, the most common of which is through a print coating process.

Clean the surface: The surface of pharmaceutical grade aluminum foil needs to be cleaned to ensure good adhesion of the coating. Surfaces are generally cleaned using appropriate cleaners and techniques.
b. Coating PVDC: PVDC solution or dispersion is used in the coating process. The solution or dispersion typically contains solvent, PVDC resin and other additives. The coating process may use a roller, spray or other suitable coating equipment.
c. Drying: After coating, the aluminum foil goes through a drying process to remove solvent or moisture from the coating. The drying method can be by hot air or oven to ensure that the coating can be completely dried.

Lamination: Once the PVDC coating is completely dry, laminate the medicinal aluminum foil with other materials. Often, another layer of packaging material, such as a polymer film, is laminated to one side of the PVDC coating to provide additional functionality and protection.

Hot pressing: During the lamination process, the PVDC coating is combined with another layer of packaging material by hot pressing. This method uses heat and pressure to ensure that the two materials are firmly bonded together.
b. Temperature and pressure control: During the hot pressing process, temperature and pressure need to be controlled to ensure that the composite between the PVDC coating and another layer of material is uniform and firm.

Subsequent processing: Once the PVDC coating is compounded with other materials, композитный материал может быть дополнительно обработан по мере необходимости, например, нарезка до необходимой формы и размера для удовлетворения требований фармацевтической упаковки.

Через вышеуказанные шаги, покрытие PVDC можно успешно компаундировать с фармацевтической алюминиевой фольгой, таким образом обеспечивая превосходные барьерные свойства и защитные свойства для фармацевтической упаковки.
