PTP Aluminum Foil
medical ptp foil for pharmacy packaging
Blister packages for Pharmaceuticals products such as capsules, tablets, pill, pastille, small-size food, candy, etc.
Protect layer (OP)/Outer printing layer/Aluminum foil based-material ( AL) inside printing layer/Bond (VC). Use in drugs blister packaging machine.
Excellent properties such as of anti- oxygen, moisture-proof, leak-proof, carryhome, antipollution, etc. Adopting hard anodized aluminum as cover material, it is easy to break aluminum foil to take out the drugs by pushing the cover. Adopting heat-seal coating material, which cannot be stripped, it can be bonded with all kinds of plastic-based materials.
According to printing method:
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).
According to specification:
According to the width of the packaging machine type used, generally divided into: 125mm, 130mm, 250mm. 65mm -500mm , these all can provide to customer according to their requirements.
Specification of PTP aluminum foils are often as follows: OP/AL 20-40μ(H)/VC and OP/AL 20-40μ(O)/VC
PTP aluminum foils are often offered as follows:

General Information:
Quality of PTP aluminum foil are often subjected to different raw materials, statement of the same raw materials, rolling progress of aluminum foil, thickness and thickness clearance of aluminum foil, pinhole scattered in aluminum foil, and surface conditions of aluminum foil.
Raw aluminums for PTP aluminum 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 aluminum foil are often alloy aluminum 1100, 1145, and 8011. Tension strength, ductile, anti-fracture strength of PTP aluminum foil made from 8011 is better, and seldom be broken when being heat-sealed with PVC.
Mechanical properties of two statements for the three raw alloy aluminum foil samples are as follows, thickness of the three samples is 0.020mm:

Thickness of PTP aluminum 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 aluminum foil, he has to offer us width of PTP aluminum foil, and whether the PTP aluminum 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 aluminum 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.
