Abstract
The utility model discloses an easy-to-tear cup cover film, and relates to the technical field of composite flexible package. The easy-to-tear cup cover film is characterized by sequentially comprising an outer-layer two-way stretching polyester (PET) film, an adhesive agent layer, a printing ink layer, an inner-layer two-way stretching polyester (PET) film and a heat-sealing lacquer (HSL) layer from outside to inside, wherein the heat-sealing lacquer layer is coated in a positioning manner, and the positioning coated region corresponds to a heat-sealing portion at the rim of a cup. The cover film provided by the utility model can be applied to a polystyrene (PS) cup, a polyvinylchloride (PVC) cup, and a polypropylene (PP) cup, has an excellent easy-to-tear function, and has the advantage of good hygiene.
Description
Technical field
The utility model relates to the composite soft packaging technical field, and being suitable for the cup material is polystyrene (PS), polypropylene (PP) and polyvinyl chloride (PVC), and requires to have the epiphragma of easily taking off function.
Background technology
Considerable food such as low-temperature yoghurt, jelly etc. use the cup packing, and the lid material that uses in the cup packing is most to be composite membrane, uses for ease of the consumer, and most lid material all requires to have easily takes off characteristic.Present domestic easily opened cup cover film all uses composite membrane, sealant in the composite membrane all uses has the film of easily taking off function, such as ethylene-vinyl acetate copolymer (EVA) film, EVA and polystyrene (PS), polypropylene (PP), has the characteristic of easily peeling off after polyvinyl chloride (PVC) heat-sealing, easily take off layer for the used epiphragma of PS cup of low-temperature yoghurt and be EVA, the material structure of most of low-temperature yoghurt epiphragmas is 60 microns of 12 microns/ink lay of biaxial stretching polyester (PET) (INK)/adhesive phase/12 microns/adhesive phase/polyethylene of biaxial stretching polyester aluminizer (VMPET) and ethene-vinyl acetate copolymerization PP TYPEs, but this material structure can't satisfy the requirement of China composite membrane sanitary standard GB9683-88, the normal hexane evaporation residue is generally 50-70mg/L, far exceeds GB9683-88 normal hexane evaporation residue 30mg/L standard; This material structure has the higher shortcoming of cost simultaneously.
201020174388.4 1 kinds of easily opened cup cover films of the patent of having announced, it has advantages of that the GB9683-88 of satisfying sanitary standard and production cost are low, but since ink lay on the surface, when sealing temperature is higher than 200 ℃, inadequate such as the ink lay heat resistance, the ink lay problem that comes off in the time of may causing sealing.
The utility model content
The utility model purpose is to overcome above-mentioned deficiency, and a kind of high temperature resistant, cost is low, wholesomeness is good easily opened cup cover film is provided.
The purpose of this utility model is to realize like this, a kind of easily opened cup cover film, the structure of described easily opened cup cover film comprises outer biaxial stretching polyester film, adhesive phase, ink lay, internal layer biaxial stretching polyester film and heat-sealing enamelled coating from outside to inside, the location coating of described heat-sealing enamelled coating, described location dispensing area is corresponding with the rim of a cup heat seal lands.
Described outer biaxial stretching polyester thickness 8-25 micron.
Described internal layer biaxial stretching polyester thickness 8-30 micron.
The thick 2-7 micron of described heat-sealing enamelled coating.
Compared with prior art, the beneficial effects of the utility model:
The utility model, outer biaxial stretching polyester film plays the printing element effect, and has good temperature tolerance, and ink lay is produced good protective effect; Ink lay embodies printed patterns; Adhesive phase is used for bonding ink lay and outer two-way polyester film; Internal layer biaxial stretching polyester film is as heat-sealing lacquer coated substrate, and the heat-sealing lacquer has good adhesive force on internal layer biaxial stretching polyester film surface; The heat-sealing enamelled coating can seal with rim of a cup, and has and easily take off characteristic; The location coating of heat-sealing enamelled coating, dispensing area is corresponding with the rim of a cup heat-seal land.The utility model easily opened cup cover film can bear 230 ℃ of heat-sealing temperatures, and cost is low, wholesomeness good.
The sour milk epiphragma that adopts the utility model scheme to produce has significant progress than common sour milk epiphragma, and be mainly manifested in: one, production cost are lower than the common sour milk epiphragma; Its two, wholesomeness is good, can satisfy GB9683-88.
