Embodiment 1-1-1

[0069] As the resin for the adsorption layer, only MB1-1 was used in the main adsorption layer, and only MB 1-4 was used in the sub-adsorption layer, and two types of three-layer films were produced by the multilayer blown film method. The film thicknesses of the two kinds of three-layer films were sub-absorbent layer / main moisture-absorbing layer / sub-hygroscopic layer=5 μm / 50 μm / 10 μm. Here, the contents of the desiccant in the entire moisture-absorbing layer and the pigment excluding the desiccant were 41% by weight and 0% by weight, respectively, so the total pigments including the desiccant was 41% by weight.

[0070] In order to improve the adhesiveness of the 5 μm sub-adsorption layer side of the obtained two types of three-layer films, the surface was subjected to rough corona treatment. A polypropylene film for PTP with a film thickness of 250 μm (trade name: CPPE0025NA, manufactured by Mitsubishi Plastics Co., Ltd.) that undergoes heat shrinkage by post-calcination is...

Embodiment 1-1-2

[0073] In Example 1-1-1, except having changed MB1-1 of the main moisture absorption layer into MB1-2, it carried out similarly to Example 1-1-1, and manufactured the packaging container for PTP or foam packaging. In this PTP or packaging container for foam packaging, the contents of the desiccant in the entire moisture-absorbing layer and the pigment excluding the desiccant are 65% by weight and 0% by weight, respectively. Therefore, the total pigment containing the desiccant is 65% by weight. .

Embodiment 1-1-3

[0075] In Example 1-1-1, instead of MB 1-1 of the main moisture-absorbing layer, MB1-1 and MB 1-3 were mixed at a mixing ratio of 50:50, except that it was carried out in the same manner, Manufacture of packaging containers for PTP or foam packaging. Here, the contents of the desiccant in the entire moisture-absorbing layer and the pigment excluding the desiccant were 41% by weight and 0% by weight, respectively, so the total pigments including the desiccant was 41% by weight.

Abstract

The present invention provides a PTP or film for foam packaging in which the heat shrinkage ratios of the outermost barrier layer and the moisture absorption layer containing a desiccant are approximately equal, which is a PTP laminated with an adsorption layer and an outermost barrier layer The film for foaming is characterized in that the adsorption layer has at least one adsorbent selected from the group consisting of physical adsorbents and chemical adsorbents.

Description

technical field [0001] The present invention relates to a PTP or blister pack film for pharmaceutical packaging and a packaging container thereof, and more specifically, to a PTP or blister pack film having the ability to absorb moisture or odor. Films and their packaging containers. Background technique [0002] In pharmaceutical packaging, foam packaging known as PTP is widely used. In many cases, even a drug with no or insufficient hygroscopicity or a drug with a strong odor is placed on the market with priority given to the efficacy of the drug. At this time, the method adopted is to use an aluminum foil pillow bag as the outer bag of the PTP, and simultaneously pack an adsorbent such as a dryer or an odor absorber. However, in the method of packing these adsorbents at the same time, the bag of the adsorbent and the bag of the drug may be mistakenly drunk, or in order to ensure the adsorption of moisture or odor of the drug by means of PTP packaging, it is only possibl...
