Abstract
A kind of packaging film described in the utility model, comprises the polyester film, aluminium foil and the polyethylene film that stack gradually compound; Described polyester film is provided with some through holes running through described poly-sour film.The compound of described polyester film and aluminium foil ensure that described packaging film has high strength and high obstructing performance, on described polyester film, the setting of through hole effectively reduces the shear strength of described polyester film to a certain extent, thus reduce the shear strength of described packaging film, easily openable, easy to use.
Description
Technical field
The utility model relates to packaging field, be specifically related to a kind of high-intensity high every and the medicinal composite package film easily torn.
Background technology
Medicine is a kind of high added value, security, the specialty goods that reliability requirement is high, except the packaging of the prepared slices of Chinese crude drugs and low-grade electuary, Key works Drug packing film is substantially based on the composite soft packaging film that the polymeric material of the pure aluminum foil and high strength with high obstructing performance is formed.
The development of composite soft packaging film starts from the middle of last century, has consequence in medical packaging field.Research staff goes out multiple composite soft packaging film according to the requirement developing of different medicine.Wherein, Chinese patent literature CN 203529091U discloses a kind of pharmaceutical pack film, comprise the PP layer be composited in turn, soft aluminium foil layer and PE hot sealing layer, subregion between adjacent two layers is provided with degradable glue, the non-adhering face of described PP layer is provided with the antibiotic layer of 30-50 nanometer, is provided with Graphene enhancement layer between described PP layer and soft aluminium foil layer.Although described packaging film has certain intensity and barrier property, however due to the PP layer and PE hot sealing layer intensity being arranged on aluminium foil layer both sides higher, in use not easily openable, needs just can open by sharp instruments, uses extremely inconvenient.
Utility model content
For this reason, to be solved in the utility model is the soft dress film of described compound in use not easily openable, uses extremely inconvenient problem, provide a kind of high-intensity high every and the medicinal composite package film easily torn.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of packaging film described in the utility model, comprises the polyester film, aluminium foil and the polyethylene film that stack gradually compound; Described polyester film is provided with some through holes running through described polyester film.
The aperture of described through hole is 0.01-0.1mm.
The quantity of through hole described in polyester film described in every square meter is 500,000-300 ten thousand.
Described polyester film is biaxially oriented polyester film.
The first adhesive phase is also provided with between described polyester film and described aluminium foil; The second adhesive phase is also provided with between described aluminium foil.
Also ink layer is provided with between described polyester film and described first adhesive phase.
The thickness of described aluminium foil is 6 ~ 30 μm.
The thickness of described polyester film is 6 ~ 20 μm.
The thickness of described polyethylene film is 20 ~ 80 μm.
Technique scheme of the present utility model has the following advantages compared to existing technology:
A kind of packaging film described in the utility model, comprises the polyester film, aluminium foil and the polyethylene film that stack gradually compound; Described polyester film is provided with some through holes running through described polyester film.The compound of described polyester film and aluminium foil ensure that described packaging film has high strength and high obstructing performance, on described polyester film, the setting of through hole effectively reduces the shear strength of described polyester film to a certain extent, thus reduce the shear strength of described packaging film, easily openable, easy to use.
Accompanying drawing explanation
In order to make content of the present utility model be more likely to be clearly understood, below according to specific embodiment of the utility model also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is the structural representation of packaging film described in the utility model;
In figure, Reference numeral is expressed as: 1-polyester film, 2-aluminium foil, 3-polyethylene film, 4-first adhesive phase, 5-second adhesive phase, 6-ink layer.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
The utility model can be implemented in many different forms, and should not be understood to be limited to embodiment set forth herein.On the contrary, provide these embodiments, make the disclosure to be thorough and complete, and design of the present utility model fully will be conveyed to those skilled in the art, the utility model will only be limited by claim.In the accompanying drawings, for clarity, the size in layer and region and relative size can be exaggerated.
Embodiment
The present embodiment provides a kind of packaging film, as shown in Figure 1, comprises the polyester film 1, aluminium foil 2 and the polyethylene film 3 that stack gradually compound; The first adhesive phase 4 is also provided with between described polyester film 1 and described aluminium foil 2; The second adhesive phase 5 is also provided with between described aluminium foil 2 and described polyethylene film 3.Ink layer 6 is also provided with between described polyester film 1 and described first adhesive phase 4.
Described polyester film 1 is provided with some through holes running through described polyester film 1, the aperture of described through hole is 0.01-0.1mm, and the quantity of through hole described in polyester film 1 described in every square meter is 500,000-300 ten thousand.
Preferably, described polyester film 1 is biaxially oriented polyester film (BOPET), and BOPET film has that intensity is high, good rigidly, transparent, glossiness high; Odorless, tasteless, colourless, nontoxic, outstanding obdurability; Its hot strength be PC film, 3 times of nylon membrane, impact strength be the 3-5 of BOPP film doubly, have fabulous wearability, folding resistance, pinhole resistance and tear resistance etc.; Heat-shrinkable is minimum, thus improves the adhesive force of its heat sealability, barrier and printing; BOPET also has good heat resistance, excellent boiling resistance, low temperature resistant freezing property, good oil resistivity and chemical-resistant etc.BOPET film is except nitrobenzene, chloroform, phenmethylol, and most of chemicals all can not make it dissolve.Meanwhile, BOPET film water absorption rate is low, water-tolerant, the food that proper packing water content is high.
