Description

Medicine packaging film capable of preventing children from being broken

Technical Field

The utility model relates to a plastic packaging technical field, concretely relates to prevent that children from pushing away broken medicine packaging film.

Background

The medicine is used as a special commodity which is closely related to the physical health and life of people, and the packaging plays a decisive role in maintaining the performance of the medicine perfectly. The amount of medicament in the packaging film of the powder for children is generally less than 50 micrograms, usually 25-50 micrograms, and the Relative Standard Deviation (RSD) between doses should not exceed 5% for a predetermined dose of medicament.

The sealing layer of the conventional medicine packaging film adopts a (polyvinyl chloride) PVC film, and pollutants such as dioxin polluting the environment can be generated when PVC is produced, recovered and destroyed in an incinerator or PVC products are accidentally combusted. PVC which is difficult to recycle is replaced by environment-friendly PP resin or PE resin in order to improve the recyclability and environmental protection of the packaging film.

Be used for children's powder packaging film to solve the security problem on the one hand, prevent that children from eating by mistake, on the other hand because the friction can form static between the plastic packaging film, leads to the powder adhesion on the packaging film for the powder can't be absorbed by completely.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide a children's powder packaging film that anti puncture, prevent static, safe easy recovery.

In order to achieve the purpose, the technical scheme of the utility model is to design a medicine packaging film for preventing children from being broken, which comprises a cover film and a bottom film, wherein the cover film comprises a PET protective layer, a cover film aluminum foil layer and a polyethylene extrusion composite layer which are arranged from outside to inside in sequence; a binder layer is further arranged between the PET protective layer and the cover film aluminum foil layer, the thickness of PET is 8-25 mu m, the thickness of the cover film aluminum foil layer is 9-40 mu m, and the thickness of the polyethylene extrusion composite layer is 15-30 mu m; the basement membrane includes nylon supporting layer, basement membrane aluminium foil layer and the closure layer that sets gradually from outer to interior, the thickness of nylon supporting layer is 25 ~ 40 mu m, and the thickness of basement membrane aluminium foil layer is 45 ~ 75 mu m, and the closure layer thickness is 15 ~ 100 mu m, become an organic whole through the hot pressing between basement membrane and the epiphragma. The aluminum foil barrier layer is added to the bottom film and the cover film of the packaging film, the packaging film is guaranteed to have good puncture resistance and good barrier property, the sealing layer is made of PP or PE films, flexibility of the packaging film is improved, the thickness of the cover film and the thickness of the bottom film are increased, and high setting property of the packaging film is improved.

As a preferable technical scheme, the number of extrusion layers of the polyethylene extrusion composite film is 5 or 7, and the thickness of each layer of extrusion film is the same. The flatness and the stiffness of the cover film are improved by increasing the number of layers and the thickness of the polyethylene extrusion composite film.

According to a preferable technical scheme, the content of high-density polyethylene in the polyethylene extrusion composite film is more than 60%, the crystallinity of the high-density polyethylene is 88-92%, and the density is 0.945-0.96 g/cm³. The high-density polyethylene is adopted to improve the recyclability of the packaging film, so that the packaging film is more environment-friendly.

Preferably, the adhesive layer is polyurethane.

As a preferred technical solution, the sealing layer is a PP film or a PE film. The PP film and the PE film are adopted to replace the traditional PVC film, so that the flexibility and the recyclability of the packaging film are improved.

As a preferred technical scheme, the sealing layer is a 5-layer PE co-extrusion film.

Preferably, the innermost layer of the sealing layer is a PE antistatic layer. 1-3% of antistatic agent is added into the PE layer, so that the antistatic effect of the PE film is improved, and powder cannot be adhered to the surfaces of the cover film and the bottom film.

The utility model has the advantages and the beneficial effects that: the utility model discloses a powder medicine packaging film epiphragma and basement membrane all are equipped with the aluminium foil barrier layer, have improved the anti puncture performance and the separation performance of packaging film, can be used for the packing of medicine to effectual children of preventing open the packing and eat by mistake, improve the security of medicine packing. The thickness of the aluminum foil and the number of layers of the PE extrusion composite film are increased in the packaging film, so that the flatness and the stiffness of the medicine packaging film are improved.
