PVC blister

The most basic material for the forming web is PVC or Polyvinyl Chloride. The principle advantages of PVC are the low cost and the ease of thermoforming. The main disadvantage are the poor barrier against moisture ingress and oxygen ingress; moreover PVC has a negative environmental connotation due to its Chlorine content. In the case of blister packaging the PVC sheet does not contain any plasticizer and is sometimes refered to as Ridgid PVC or RPVC. In the abscence of plasticizers, PVC blisters offer structural rigidity and physical protection for the pharmaceutical dosage form. On the other hand, the blister cavity must remain accessible by the push-through effect and the formed web may not be too hard to collapse when pressed upon: for this reason the PVC sheet thickness is typically choosen between 200µ to 300µ depending on the cavity size and shape. Most PVC sheets for Pharmaceutical blisters are 250µ or 0.250mm in thickness. Typical values for the Water Vapor Transmission Rate (WVTR or MVTR ) of a 250µ PVC film are between 0.30 and 0.35 g/m2/day measured at 38°C/90%RH and the Oxygen Transmission Rate (OTR) is around 20 cc/m2/ day. In order to overcome the lack of barrier properties of PVC film, it can be coated with PVDC or laminated to PCTFE to increase the protective properties. Multi-layer blister films based on PVC are often used for pharmaceutical blister packaging, whereby the PVC serves as the thermoformable backbone of the structure. Also, the PVC layer can be colored with pigments and/or UV filters. The European Pharmacopoeia (EP) references the requirements for PVC blister packs for Pharmaceutical primary packaging it the monograph EP 3.1.11 "MATERIALS BASED ON NON-PLASTICISED POLY(VINYL CHLORIDE) FOR CONTAINERS FOR DRY DOSAGE FORMS FOR ORAL ADMINISTRATION". In order to be suitable for Pharmaceutical blister packs, the PVC formulation also needs to comply with the US Pharmacopoeia <661>; EU food legislation ; US 21.CFR and Japanese food contact requirements.

Blister Packing

Perfect Protection

Widely used for display and protection of a myriad of goods, blister packing is a perennial favourite that is always in great demand in a large number of industries.

Long-time packaging industry veterans in ShangHai are helping to meet ever-increasing market demand through their factories on the Chinese mainland, where low production costs ensure competitive pricing and quality products.

A classic example of this customer-centric trend is Shanghai XONGYING plastic Vacuum Thermoform packing factory , whose products include PS blister trays for electronic parts and flocked-blister cutlery trays, as well as clamshells for small radios or MD players.

XongYing's blister packing products are made with PVC, PET, PS and PP, mostly from Taiwan.

The 12-year-old firm operates two blister-packing factories in NanHui, in Shanghai, on the mainland.

XONGYING requires minimum order values of about US$3,000, which can be delivered about a month after order confirmation, depending on the quantity.

Focusing more on the feminine market is Chiu Ming Polyethlene Products Fty Ltd, which produces transparent and coloured, flocked and unflocked blister trays for multinational perfume and cosmetic manufacturers.

We use materials from Taiwan, the mainland and the US like PVC, PS and environmentally friendly PP, APET and PETG.

XONGYING's ISO 9001-certified, 10,000-square-foot factoryb150 workers and produces US$2,000 minimum order values for delivery two weeks after confirmation.

Perfectech's products include anti-static PVC trays for electronic parts, PS stationery trays and flocked PVC trays for customer-specific purposes.

Bright, cute styles are a particular forte of Charter Bright Industries Co Ltd, which makes red and purple PVC blister trays for toys as well as PVC trays for candies, including a transparent version in the shape of a Christmas tree.
