Abstract
The utility model discloses an easy uncovered suppository packaging film, which comprises a blocking layer and a heat sealing layer. The blocking layer is an aluminum foil layer or a polyvinyl chloride layer, the heat sealing layer is combined with the blocking layer by the means of adhering; the heat sealing layer is a composite layer structure and is sequentially formed by one to two polythene layers and one modified polythene layer along a direction far from the blocking layer. The packaging film has the advantages of greatly lowering manufacturing cost on condition of ensuring the thickness of a heat sealing film.
Description
Technical field
The utility model belongs to the plastic packaging film technical field, is specifically related to a kind of easy-to-uncover suppositorium packaging film.
Background technology
Patent documentation CN2507802Y discloses a kind of medicine composite package film, be composited by trilaminate material, its interlayer is an aluminium lamination, outside face is attached with the polyamide polymers layer, inside face adheres to polyvinyl chloride layer, and its shortcoming is that the hardness of this drug packaging film is higher, the elasticity deficiency, influence packing effect.
Patent documentation CN2639220Y discloses a kind of suppository composite packing film, with the film layer is basal layer, on film layer, adhere to and be provided with soft aluminium foil layer or polyvinyl chloride hard lamella, the thickness of described film layer is 25 to 40 microns, the thickness of described soft aluminium foil layer is 40 to 50 microns, and the thickness of perhaps described polyvinyl chloride hard lamella is 100 to 150 microns.The elasticity and the forming characteristics of the utility model suppository composite packing film are better, but its shortcoming is directly to adopt polyethylene as hot sealing layer, after two-layer such complex film is to the heat-sealing that changes, because the viscosity between the polyethylene heat-sealing layer is too strong, cause and to open two-layer, and can only select to tear, use and be not very convenient.
The utility model content
The purpose of this utility model provides a kind of under the prerequisite that guarantees heat-sealing film thickness, reduces the suppositorium packaging film of manufacturing cost.
The technical scheme that realizes the utility model purpose is: a kind of easy-to-uncover suppositorium packaging film comprises barrier layer and hot sealing layer; Described barrier layer is aluminium foil layer or polyvinyl chloride layer, and described hot sealing layer and described barrier layer adopt adhesive means to be combined with each other; Described hot sealing layer is a lamination layer structure, is one to two layers of polyethylene layer and one deck modified poly ethylene layer successively along the direction away from described barrier layer.
In the technique scheme, described hot sealing layer is a three-decker, is first polyethylene layer, second polyethylene layer and one deck modified poly ethylene layer successively along the direction away from described barrier layer.
In the technique scheme, described hot sealing layer is that three-layer co-extruded method is made.
In the technique scheme, another side away from described hot sealing layer of described barrier layer also is provided with ink lay and gloss oil protective cover successively.
In the technique scheme, described modified poly ethylene layer is raw materials used to be: polyethylene: 100 parts; Polybutene or modification polybutene: 5 to 40 parts; Described umber is parts by weight.
The good effect that the utlity model has:
(1) many times, the user can propose exacting requirements to the thickness of heat-sealing film, and the polyethylene floor height more common owing to the manufacturing cost of special-purpose modified poly ethylene hot sealing layer is a lot, so cause cost high; And the utility model then can reduce the use amount of special-purpose modified poly ethylene under the prerequisite that guarantees heat-sealing film thickness, has reduced cost.

The specific embodiment
(embodiment 1, easy-to-uncover suppositorium packaging film)
Fig. 1 is first kind of structural representation of easy-to-uncover suppositorium packaging film of the present utility model; Shown first kind of specific embodiment of the utility model.
Present embodiment is a kind of easy-to-uncover suppositorium packaging film that is exclusively used in packing suppository, comprises ink lay 3, gloss oil protective cover 4, barrier layer 1 and hot sealing layer 2; Described barrier layer 1 is an aluminium foil layer, and described hot sealing layer 2 and described barrier layer 1 adopt adhesive means to be combined with each other; Described hot sealing layer 2 is a three-decker, is first polyethylene layer 51, second polyethylene layer 52 and modified poly ethylene layer 6 successively along the direction away from described barrier layer 1; Described modified poly ethylene layer 6 is raw materials used to be: polyethylene: 100 parts; Polybutene: 10 parts; Described umber is parts by weight.In other embodiments, described modified poly ethylene layer 6 raw materials used can in following prescription, selection: polyethylene: 100 parts; Polybutene or modification polybutene: 5 to 40 parts; Described umber is parts by weight.
Described hot sealing layer 2 is to adopt three-layer co-extruded method made.The polyethylene floor height more common owing to the manufacturing cost of modified poly ethylene layer 6 is a lot, can reduce the thickness of special-purpose modified poly ethylene layer 6 like this, cost-cutting.
The easy-to-uncover suppositorium packaging film of present embodiment, with hot sealing layer in twos relatively hot be honored as a queen, sample thief detects, the peel strength between the two-layer modified poly ethylene hot sealing layer is 4N/15mm to 15N/15mm; Be fit to very much open, have well easily taking off property with hand.
(embodiment 2, easy-to-uncover suppositorium packaging film)
Fig. 2 is second kind of structural representation of easy-to-uncover suppositorium packaging film of the present utility model; Shown second kind of specific embodiment of the utility model.
This enforcement is substantially the same manner as Example 1, and difference is: described hot sealing layer 2 is one polyethylene layer 5 and one deck modified poly ethylene layer 6 along the direction away from described barrier layer 1 successively; Described modified poly ethylene layer 6 is raw materials used to be to adopt the foregoing description 2 described raw materials.In addition, barrier layer described in the present embodiment is a polyvinyl chloride layer.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And these belong to conspicuous variation or the change that connotation of the present utility model extends out and still belong to protection domain of the present utility model.
