PVC PVDC Film Specifications

PVC (polyvinyl chloride) and PVDC (polyvinylidene fluoride) films for blister packaging are common packaging materials, widely used in pharmaceutical, food and other industries. PVC film materials have good mechanical strength, flexibility and corrosion resistance. Good processing performance, easy to thermoplastic processing molding, good chemical stability, good corrosion resistance to most acids, alkalis and salts, good flame retardant, not easy to burn. PVDC film materials with high barrier, toughness, heat shrinkage and chemical stability, excellent printing and heat sealing performance.

PVC/PVDC films for blister packaging are available in a wide variety of specifications to meet the needs of different customers. The following are common pvc pvdc film specification and parameters:

– Main Material: Composite material of PVC (polyvinyl chloride) and PVDC (polyvinylidene chloride).

– Structural features: Combines the flexibility of PVC with the barrier properties of PVDC to provide excellent protection.

– Thickness range: Usually between 0.1mm and 1mm, the exact thickness can be customized according to customer needs. For example, some products offer a fixed thickness of 0.25mm, while others offer different weight options ranging from 40gsm (grams per square meter) to 120gsm, which roughly correspond to different film thicknesses.

– Weight options: common weight specifications are 40gsm, 60gsm, 90gsm and 120gsm, with the higher the weight, the thicker the film usually is.

– Width: A wide range of widths are available, from 50mm to 1600mm, depending on production equipment and customer requirements.

– Length: lengths can often be customized to suit different blister pack size requirements.

– Shape: Available in roll form to meet different processing and usage requirements.

– Color Options: Transparent, white, and custom color options are available to meet customer needs for packaging appearance.

– Appearance characteristics: Smooth surface and high gloss helps to enhance the overall texture of the product.

Performance characteristics of PVC PVDC film are:

– Barrier performance: The PVDC layer provides excellent barrier performance, effectively preventing the penetration of oxygen, moisture, etc., and protecting the product inside the blister from the external environment.

– Heat sealing performance: it has good heat sealing performance, easy to seal and combine with the blister material to ensure the integrity of the package.

– Mechanical strength: with a certain mechanical strength, able to withstand a certain degree of external force and pressure, to protect the products inside the blister from damage.

Please note that the above pvc pvdc film specification and parameters are for reference only, the specific specifications may vary depending on the manufacturer, production equipment and customer demand. When choosing PVC/PVDC film, it is recommended to choose according to specific application scenarios and needs.
