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.

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.
