Abstract
The embodiment of the invention discloses a high-barrier composite packing paper. The packing paper has a six-layer composite structure, the six layers comprises, from inside to outside, a bonding layer, a high-barrier layer, a water-based varnish layer, a paper base, a printing layer and an isolation film, and the layers are mutually compounded and are integrated. By adopting the above scheme, the high-barrier packing paper having the advantages of non-toxicity and high stability is provided for the packing of medicines and foods having volatile substances, and a cold seal adhesive is utilized to realize the sealing of the packing paper at normal temperature in order to effectively protect the effects of the medicines and the safety of the foods.
Description
Technical field
The present invention relates to a kind of wrapping paper, relate in particular to a kind of composite packaging paper with high obstructing performance.
Background technology
At present the kind of wrapping paper is a lot, but need to be applied to seal, hinder oxygen etc. during pack environment, more high to the structural requirement of wrapping paper.At present, the PVDC(polyvinylidene chloride) film, stable performance wet with the resistance oxygen of excellence, resistance makes it become the preferred material of packaging for foodstuff, medicine packing, but when coating paper surface and have high temperature due to PVDC at present, the easy problem such as distortion of paper, make the PVDC range of application be restricted.And when being applied to drug packages, wrapping paper is at the general heat sealing method that adopts of sealing, for there being volatile medicine easily to produce volatilization when the high temperature hot-seal, makes the property of medicine of medicine produce in various degree loss.
Summary of the invention
Embodiment of the present invention technical problem to be solved is, a kind of high-barrier composite packaging paper is provided, and can smoothly PVDC be applied to the papery packing, utilizes simultaneously the cold seal technology, completes the sealing of packing under normal temperature.
In order to solve the problems of the technologies described above, the embodiment of the present invention provides a kind of high-barrier composite packaging paper, described wrapping paper is six layers of composite construction, is adhesive layer, high-obstruction, water-based gloss oil layer, paper substrate, printed layers, separating film layer from inside to outside, and each layer is mutually compound and be overall structure.
Wherein, described adhesive layer is the cold seal glue coating layer.
Wherein, described high-obstruction is the PVDC(polyvinylidene chloride) coating layer.
Wherein, described paper substrate is the medical or edible paper of high density.
Wherein, described separating film layer is the wax layer.
Further, described bonding depth is 20 ~ 35 μ m, and described high-obstruction thickness is 12 ~ 25 μ m, and described water-based gloss oil layer thickness is 2 ~ 4 μ m.
Implement the embodiment of the present invention; can pack for medicine, packaging for foodstuff etc. has volatile materials provides a kind of avirulence, stable high high-barrier wrapping paper; and utilize cold seal glue to realize under normal temperature, wrapping paper being sealed, can effectively protect the drug effect of medicine and the security of food.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
With reference to structural representation of the present invention shown in Figure 1.
High-barrier wrapping paper of the present invention comprises paper substrate 13, when in prior art, PVDC coats paper, when having high temperature, paper produces the defectives such as change of shape and infiltration, the present invention utilizes at paper substrate upper surface coating water-based gloss oil and forms one deck water-based gloss oil layer 14, further be coated with again PVDC on water-based gloss oil layer 14, and utilize the segmentation temperature to dry formation high-obstruction 15.
The thickness of water-based gloss oil layer 14 is 2 ~ 4 μ m, best results when thickness is 3 μ m.
High-obstruction 15 thickness are 12 ~ 25 μ m.
In the printed layers 12 of paper substrate 13 lower surfaces for packing, be separating film layer 11 on it, separating film layer 11 is a wax layer, wherein comprises the EVA(ethylene-vinyl acetate copolymer) be the 20%-30%(weight ratio).
Further, for reaching the purpose of sealing under normal temperature, use cold seal glue location coat binding layer 16 on high-obstruction 15, its thickness is 20 ~ 35 μ m, pushes the sealing that can complete under normal temperature by external force only two need to be scribbled the high-barrier extrusion coating paper correspondence of cold seal glue when sealing after.
Above disclosed is only a kind of preferred embodiment of the present invention, certainly can not limit with this interest field of the present invention, and the equivalent variations of therefore doing according to claim of the present invention still belongs to the scope that the present invention is contained.
