Blister packages, sometimes called bubble packs, are made of a cardboard backing with individual pills or groups of pills inserted into a small plastic pouch that is covered by foil on the back side. This type of pharmaceutical packaging is often referred to as unit-dose packaging, because one blister equals one dose. Unit-dose packaging is often used by nursing homes and long-term care facilities because it is easier for staff members to count the remaining medication and to distribute it properly to patients. Easy-to-open blister packs are also helpful for patients who struggle with bottles or vials for medications they take at home.
PTP blister foil features oxygen resistance, moisture proof, leak proof, pollution proof, light proof, light weight, high tension strength and low shrink, and a degree of tamper resistance, and PTP blister foil can be easily cut in automatic production line, moreover, being easy pressed through of PTP blister foil distinctive character, comparing to other packing material, which ensures drugs can be drawn out easily.
Dirante PTP blister foil are manufactured by the proven technology, the qualified materials, the state-of-the-art machines and skilled workers to meet the high quality requirements of the pharmaceutical & food Industry, and it is registered and active in China FDA Bureau now.
Pharmaceutical Aluminum blister foil is coated with primer and heat sealing lacquer on different side of plain aluminum foil, but without printing.
The primer coating is suitable for printing in customer’s plant, by solvent/ alcohol-base ink. It also withstands the high temperature of heating during blister packaging process, to guarantee the printing layout.
The heat sealing lacquer is food grade, and easy to seal with PVC, PVC/PVDC, Alu-Alu bottom foil, PP, etc, by heating on blister packaging machine.
PTP aluminum foil can be unprinted or printed. Printed foil can be printed on one side or both sides.
Printing of PTP aluminum foils can be available in plain foil(no printing), printing foil (one-sided printing, two-sided printing, single-color print, double color printing, polychrome printing), color foil (one-sided golden color, two-sided golden color, green bottom color, each kind of colored bottom color), forgery-proof (stealth writing, design, positive and negative printing), while single side or double sides printing assure better appearance upon request.

Plain or printed aluminum foils for blister packs are used mostly in the pharmaceutical industry to package tablets and capsules in a manner that they remain protected from ambient contamination. These are hard aluminum foils where one side is coated with heat seal lacquer and the other side is unprinted or printed to facilitate pharmaceutical blister packaging. Most common foil thicknesses used in pharmaceutical blister packaging are those of 20µ/25µ/30µ. The heat seal lacquer is a colorless vinyl resin conforming to the applicable international regulations for pharmaceutical applications. The HSL is suitable for heat sealing to PVC/PVDC coated PVC films. The range of HSL can vary from 4gsm -8gsm depending on the speed, product and packaging.
Blister pack for healthcare products in tablets, capsule, softgel, etc
Since the product is individually sealed into each blister, it is easy to carry and friendly to customer to consume as the using indication printed on the lid foils. Meanwhile the manufacturer’s name or logo printing is another good way to promote and market your products and company.
