Description

technical field

[0001] The invention relates to a punchable blister packaging material for medicine, food, health products and the like.

[0002] The invention also relates to the production process of the packaging material. Background technique

[0003] In the known technology, in order to prevent moisture and volatilization of capsule granule medicines, the packaging for plate-mounted capsules and tablets is almost all sealed with transparent blisters. This transparent bubble cover formed by thermosynthesis of common aluminum foil and polyvinyl chloride PVC plastic is still not ideal enough in terms of water vapor transmission and oxygen barrier. In particular, it cannot block the light radiation including ultraviolet light, and cannot fundamentally solve the quality problems that the medicine is volatile, easy to be affected by moisture, deteriorated by light, and the curative effect is doubled, so that the active ingredients of the medicine within the validity period a...
