specific Embodiment approach 1

[0030] Embodiment 1: An aluminum-plastic composite film for anti-counterfeit suppository packaging according to this embodiment, which includes a protective coating, a UVB absorbing layer, a fluorescent ink layer, an adhesive layer, a composite layer, an easy-to-tear layer and a sealing layer;

[0031] The protective coating is a high-molecular polymer coating formed after the high-molecular polymer resin is diluted to a certain viscosity with an appropriate amount of ethyl acetate, mixed evenly by adding 800ppm slippery agent, and then coated on the bright surface of soft aluminum foil and dried. ;

[0032] The adhesive layer is a layer formed after the two-component polyurethane adhesive is cured; the main agent: curing agent mass ratio is 20:2.4;

[0033] The composite layer, the easy-to-tear layer and the sealing layer are stacked according to three or seven layers, ensuring that the composite layer and the sealing layer are on the outer layer, and the easy-to-tear layer i...

specific Embodiment approach 2

[0040]Embodiment 2: This embodiment differs from Embodiment 1 in that: the aluminum foil used in the aluminum foil film has an elongation rate of 0.5-8%, a thickness of 30-60 μm, a clean surface and a surface tension of 72 mN / m. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0041] Specific embodiment three: the difference between this embodiment and specific embodiment one is: the total thickness of the composite layer, the easy-to-tear layer and the sealing layer is 40-60um; wherein, the composite layer and the sealing layer each account for 25% of the total thickness. %, and the remaining 50% is the easy-to-tear layer. Others are the same as in the first embodiment.

Abstract

The invention discloses an aluminum-plastic composite film for packaging an anti-counterfeiting suppository and a preparation method of the aluminum-plastic composite film, relates to the field of aluminum-plastic composite films, and aims to solve the problems of difficulty in tearing, easiness in uncovering or excessive easiness in uncovering and poor anti-counterfeiting effect in the conventional suppository packaging. The aluminum-plastic composite film comprises a protective coating, a UVB absorption layer, a fluorescent ink layer, an adhesive layer, a composite layer, an easy-to-tear layer and a sealing layer. The method provided by the invention comprises the following steps that fluorescent ink, a UVB absorption coating liquid and a high-molecular polymer are sequentially coated onthe bright surface of soft aluminum foil and dried to form a fluorescent ink layer, a UVB absorption layer and a protective coating, the composite layer, the easy-to-tear layer and the sealing layerare integrally formed into a thin film through a co-extrusion film blowing machine, and the fluorescent ink layer, the UVB absorption layer, the protective coating and the thin film are compounded through a dry-type compounding machine by using an adhesive and cured to form the aluminum-plastic composite film. The suppository package manufactured through the method is easy to tear and good in uncovering performances, and the sealing strength can reach 4.5-6.5 N / 15 mm. The method is applied in the field of packaging.

Description

technical field [0001] The invention relates to the field of aluminum-plastic films, in particular to an aluminum-plastic composite film for anti-counterfeit suppository packaging and a preparation method thereof. Background technique [0002] Suppository packaging requires high absorption performance and good sealing performance to ensure long-term preservation of suppositories. In addition, it also needs to have good deep forming performance and easy tearing and peeling performance, so as to meet the filling of suppositories and facilitate the use of consumers. Currently, the suppository packaging used in the market has the technical defect of being difficult to tear, easy to peel off or excessively easy to peel off after sealing. If the suppository packaging is not easy to tear off and easy to peel off, tearing it hard will cause damage to the suppository or destroy other unit suppository packaging. If it is too easy to peel off, the suppository package will easily cause...
