What is the difference between PVC and PVDC foil?
What is the difference between PVC and PVDC foil?
PVC stands for polyvinyl chloride while PVDC stands for polyvinylidene chloride. The key difference between PVC and PVDC is that PVC is made of chloroethene monomers, whereas PVDC material is made of vinylidene chloride.
Why is PVC used on blister pack?
The plastic is either heat-sealed to the card or slid through additional plastic pieces on each side. This type of blister packaging is used to make the packaging stronger (the corners are harder to bend, for instance) and better-looking.
What is PVDC foil?
PVDC. Polyvinylidene chloride (PVDC) can be coated onto a PVC film to obtain very high moisture and oxygen barrier properties depending on the coating weight. PVDC coated blister films are the most common and prevailing barrier films used for pharmaceutical blister packs.
What is the difference between blister and strip?
The difference between a strip pack and blister pack is that a strip pack does not have thermo-formed or cold formed cavities; the strip pack is formed around the tablet at a time when it is dropped to the sealing area between sealing moulds.
Is PVDC bad for the environment?
PVDC is considered a contaminant to well-established recycling streams (such as PE) because it degrades at low temperatures, rendering large portions of the mainstream polymer unusable. Even relatively small quantities of PVDC are reported to have detrimental impact on the quality of the recyclate.
What is PVC foil door?
PVC foil is the most used coating material today. PVC doors, which are resistant to UV rays, long-lasting, and high quality, are one of the most preferred door types today. PVC door foil is a type of coating that is highly resistant to water and moisture.
What are the specifications of PVC/PVDC foil?
Specifications of PVC/PVDC Foil 1 PVC film thickness of 60-400 micron 2 PVC film width of 50-1200 mm 3 Different load of PVDC, 40/60/90/120 gsm More
Why choose aluminium foil blisters?
ALUMINIUM BLISTER FOIL • Ultimate protection to moisture, light and oxygen • Excellent formability being suitable for deep draw blisters ALUMINIUM PAPER FOIL Aluminium foil is soft with different thickness from 7 – 9 micron. One side is laminated with paper for printing and inside laminated with PE for sealing.
What are the advantages of aluminium foil PVC packaging?
• Excellent thermoforming characteristics • Strong sealing with aluminium foil PVC film is used in pharmaceutical packaging with different thickness from 120 – 500 micron and available in wide range of colors. They are suitable for both rotary and flat bed blister packing machine.
What material is used for blister packaging in pharmaceuticals?
PVC (Polyvinyl chloride) and PVDC (polyvinyldine chloride)are used in pharmaceuticals as primary packaging materials, which protect pharmaceutical product against Oxygen and odour, moisture , water vapour transmission ,contamination and bacteria . These properties make PVC/PVDC the material of choice for blister packaging.
