What Is Cold Forming Blister Foil

Unlike the common high-temperature blister packaging, cold forming blister foil is stamped at low temperature. Tropical aluminum blister packaging is not a substitute for cold-formed aluminum, but a different packaging solution for different medicines with different moisture-proof requirements and display effects. The main difference between tropical aluminum and cold-formed aluminum in function is its moisture-proof effect.

Alu alu blister foil is a new type of pharmaceutical packaging product and is also the packaging material with the best shelf life. It can almost completely isolate water vapor, oxygen and ultraviolet rays. A single blister forms an independent part and has no effect on other medicines.

Since cold stamping hard sheets need to be stamped, the thickness of the aluminum foil used is much thicker than that of ordinary composite films. Generally, 45μm thick aluminum foil is used. For applications where the blister is shallow, the thickness of the aluminum foil can be appropriately reduced, generally to a minimum of 30μm. For applications where the blister is particularly deep (≥15mm), or where the cold-stamped hard sheet is required to have good stiffness, the thickness of the aluminum foil can be appropriately increased, up to 70μm.

PTP aluminum foil is more common than the cold forming aluminum foil. The main difference between PTP and general blister packaging is that it uses pressurization to fit aluminum foil and plastic blister. This method uses the blister to contain the tablets and the aluminum foil to seal to isolate moisture, preventing the tablets in the package from oxidation and deterioration, or being polluted by the environment. In addition to using transparent plastic shells, PTP packaging can also choose opaque blister shells to further prevent the medicine from deteriorating due to light.

Medical aluminum foil packaging manufacturers set strict raw material selection standards, which not only ensures product purity, but also provides a hygienic and reliable barrier for drugs. Welcome to inquire alu alu blister foil specification from us.
