Abstract
The utility model provides a separation packaging film with changeable colour pattern is formed by the multilayer film complex, includes protection film skin, printing opacity pattern layer, the rete that discolours, barrier film bottom from top to bottom in proper order. This packaging film has excellent separation nature, and has the pattern of changeable colour, and is very pleasing to the eye, can apply to the packing tectorial membrane of food and the multi -purpose commodity of teenagers.
Description
Technical field
The utility model relates to a kind of packaging film, particularly relates to a kind of changeable colour pattern that has, and has a packaging film of excellent barrier.
Background technology
At present, along with the development of electric business, logistics gets more and more, and get more and more, and packing case volume is very large to the demand of packaging, and waste material, as adopted film with alternative packing case, the loading amount of logistics will be increased undoubtedly greatly, and reduce the consumption of material.But current packaging film function singleness, except meeting except the requirement of mechanical property, often higher Functional Requirement cannot be met, realization as all more difficult in barrier, antibiotic property etc., and packaging film outward appearance is generally single, cannot meets, to beautiful and fashion, there is higher youthful requirement.
Utility model content
The technical problems to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, provides a kind of and have excellent barrier and the packaging film of pattern changeable colour.
The utility model solves the technical scheme that its technical problem adopts:
There is a barrier package film for changeable colour pattern, be composited by multilayer film, comprise diaphragm skin, light-transparent pattern layer, variable color rete, Obstruct membrane bottom from top to bottom successively.
Further, described diaphragm skin is thermoplastic plastic membrane, and can be polyethylene film, polypropylene screen, polystyrene film, polyester film as PET film etc., its thickness is between 0.3-0.8mm.
Further, described light-transparent pattern layer is thermoplastic plastic membrane, by the division composition pattern in color and region on film, ensure still can to realize in colouring region light through.
Further, described variable color rete is thermoplastic plastic membrane, and the dome-type of its lower surface distribution caves in its diameter between 1-2mm, arranges in matrix, and the distance between adjacent dome-type depression, between 1-2mm, is provided with metal sputtering layer outside variable color rete lower surface.
Further, described metal sputtering layer is the copper film layer or aluminum membranous layer that are covered by vacuum sputtering.
Further, described Obstruct membrane bottom is multi-layer co-extruded EVOH film or multi-layer co-extruded nylon membrane, and its co-extrusion number of plies is between 2-5 layer.
Further, bind with adhesive between each layer.
Accompanying drawing explanation
Fig. 1 is that the utility model one implements schematic cross-section.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to Fig. 1, a kind of barrier package film with changeable colour pattern, is composited by multilayer film, comprises diaphragm skin 1, light-transparent pattern layer 2, variable color rete 3, Obstruct membrane bottom 4 from top to bottom successively.
Described diaphragm outer 1 is polypropylene screen, and its thickness is 0.4mm.
Described light-transparent pattern layer 2 is polyethylene film, by the division composition pattern in color and region on film, ensure still can to realize in colouring region light through.
Described variable color rete 3 is polyethylene film, and dome-type its diameter that caves in of its lower surface distribution is 1.5mm, arranges in matrix, and the distance between adjacent hemisphere depression is 1.5mm, is provided with metal sputtering layer 3-1 outside variable color rete 3 lower surface.
The copper film layer that described metal sputtering rete 3-1 is covered by vacuum sputtering.
Described Obstruct membrane bottom 4 is multi-layer co-extruded EVOH film, and its co-extrusion number of plies is 3 layers.
Described each layer binds with adhesive.
Above detailed introduction is done to a kind of preferred embodiment of the present utility model.Described detailed description of the invention just understands core concept of the present utility model for helping.It should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify the protection domain also belonging to the utility model claim.
