Blister packaging aluminum foil holes

Blister packaging is one of the most widely used and fastest developing flexible packaging materials in the pharmaceutical industry. It is the main packaging form of solid drug formula in China. It has excellent air tightness, excellent moisture resistance, good oil resistance, drug resistance, solvent resistance, excellent oxygen resistance, water vapor and carbon dioxide gas in the air, which can meet the special requirements of blister packaging medicine. Use aluminum foil as the printing medium, its surface must be clean, bright, high quality. Aluminum foil coating can be used strictly to ensure that the aluminum foil substrate is closely related to the composite coating of the blister cover. Aluminum foil is non-toxic and tasteless, with good electrical conductivity and opaque light, very resistant to humidity, endurance and gas odor protection material, can more effectively protect the packaging of drugs, packaging is a metal film can not be evaporated, there is a special coated aluminum coating can not completely replace aluminum foil. However, the aluminum foil may crack in the middle during the opening process and become irregular after extrusion and folding, affecting the appearance, especially the packaging of circular bubbles.

The purpose of this technique is to provide a blister pack with a circular hole corresponding to a bubble through a composite plastic film on the aluminum foil. During the opening process, aluminum foil is a piece of structure, one piece. In the process of use, the overall beauty has been improved. In order to achieve this goal, the following technical solutions are provided: the bubble shell is circular, the holes on the hole film are circular, and the hole arrangement is linear, evenly distributed and circular; The shape of the hole determines the shape of the special hole, and each hole corresponds to the bubble distribution. In addition, on the contact surface between the aluminum foil and the shell, when the special aperture is less than or equal to the inner diameter of the shell, the aluminum foil opens.

A set of open-hole aluminum foil consisting of a bubble wrap layer, an aluminum foil and a perforated film, with one side bonded and the other side coated with an adhesive to cover and seal the bubble wrap layer; The bubble is round and the hole in the pore film is round. The holes are perforated in a straight line, evenly distributed and round. The shape of the hole determines the shape of the special hole, and each hole corresponds to the bubble distribution.
