PTP blister foil

“PTP” in PTP blister foil is abbreviated from “Press through Packing”, in Europe, “PTP” is known as “Press through Foil”, in China, PTP blister foil is named “Pharmaceutical PTP blister foil”, PTP blister foil that is also known as blister foil or push-through lidding foil is offered for heat sealing with PVC, PVDC-coated PVC, PP for pharmaceutical purpose in blister packing process, such as capsules, tablets, pill, and etc. PTP blister foil features oxygen resistance, moisture proof, leak proof, pollution proof, light proof, light weight, high tension strength and low shrink, and PTP blister foil can be easily cut in automatic production line, moreover, being easy pressed through of PTP blister foil distinctive character compare to other packing material ensures drugs can be drawn out easily.
PTP blister foil can be unprinted foil and printed foil, and printed foil can be printed on one side or both sides, weight of PTP blister foil varies due to unprinted or different printed.

PTP blister foil is offered for pharmaceutical purpose in blister packing process, such as capsules, tablets, pill, lozenges and etc. 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 compare to other packing material ensures drugs can be drawn out easily.
Basic configuration of PTP blister foil is Protect layer (OP)/Outer printing layer/Aluminum foil based-material (AL) inside printing layer/Bond (VC).

General Information:

Quality of PTP blister foil are often subjected to different raw materials, statement of the same raw materials, rolling progress of blister foil, thickness and thickness clearance of blister foil, pinhole scattered in aluminum foil, and surface conditions of aluminum foil.

Raw aluminums for PTP blister foil can be hard aluminum (often called “H18”) or soft aluminum (often called “0”), hard aluminum are those not being softened aluminum foil after rolling (aluminum foil are not annealed after rolling), while soft aluminum are those being softened aluminum foil after rolling (aluminum foil are annealed enough after rolling).

Raw aluminums for PTP blister foil are often alloy aluminum 1100, 1145, and 8011. Tension strength, ductile, anti-fracture strength of PTP blister foil made from 8011 is better, and seldom be broken when being heat-sealed with PVC.

Thickness of PTP blister foil is usually 0.020mm. GB 3198-2003 aluminum and alloy aluminum foil specifies that thickness of raw aluminum should be 0.020±8%mm, most manufacturers control thickness clearance of raw aluminum foil within 5%, that is thickness of aluminum foil is 0.020±0.001mm. YBB00152002 specifies that coating thickness clearance should be within ±10.0%, that is thickness of aluminum foil with coating is 0.024±0.003mm.

When customer asks inquiry for PTP blister foil, he has to offer us width of PTP blister foil, and whether the PTP blister foil shall be printed or not. We are willing to offer customers PTP aluminum foil sample without charge for his test, if customers test machine is bought from China, we are willing to send the asked sample to the test machine manufacture.

PTP aluminum foil is offered in rolls, and these rolls are packed in cardboard boxes. Many PTP blister foil blister packaging machines use heat and pressure via a die to form the cavity or pocket from a roll or sheet of plastic. In recent years, improvements in cold forming, specifically allowing steeper depth/angles during forming, which minimizes the amount of material used for each cavity—have helped this technology increase. The main advantages of the plastic-based blister pack are its more compact size compared to cold formed aluminum and its transparency to see the product.
