Abstract
The invention discloses a composite structure high barrier resin molded sheet material, and a processing method thereof. The sheet material comprises an outer film layer, a binding layer and an inner film layer. The outer film layer and the inner film layer are bound by the binding layer. The outer film layer is a polyethylene terephthalate (PET) sheet or a polypropylene (PP) sheet, and the inner film is a multilayer co-extruded film containing a barrier material, wherein the barrier material is a polyamide barrier layer or a polyvinylidene chloride barrier layer. The multilayer co-extruded film is processed through a downdraft water-cooling film-blowing method, or a film-casting method. Because the co-extruded film with an excellent obstructing performance is composed with a blank plastic sheet material, good moldability of the plastic sheet and excellent obstructing performance of the co-extruded film are integrated. Compared with sheet materials with a same thickness, the composite sheet material is substantially advantaged in flexibility. Therefore, multi-functional qualities of the sheet material can be realized, consumptions can be reduced, environment can be protected, and cost can be optimized.
Description
Technical field
The present invention relates to overall plastic composite sheet, be specifically related to a kind of composite construction high-barrier resin forming sheet material, this sheet material can be used for punch forming and is used for packaging for foodstuff, also is applicable to fields such as medicine packing and cosmetic package.
Background technology
At present, be used in sheet material on the punch forming packing on the market and mainly be simple polychlorovinyl sheet material (PVC), polystyrene (PS), high density polyethylene (HDPE) (HDPE), polypropylene (PP), PETG (PET) etc., these sheet materials have occupied the market of most stamping forming packaging markets and most of medicine blister package.But it is that barrier is not good that the sheet material of these materials has a common deficiency, and the packaged products shelf-life is all shorter.Using more at present at the food and medicine packaging field, barrier material is the packing that polyvinylidene chloride (PVDC), ethylene-vinyl alcohol copolymer (EVOH) or nylon (PA) are done barrier material.Wherein can carry out the very rare of boiling, but have a lot of formed package requirements can carry out boiling in actual applications.
But generally being meant under 120 ℃ or 135 ℃ of conditions, boiling carries out boiling sterilization.In sheet material commonly used with poly-to dioctyl phthalate second diester (PET) sheet and polypropylene (PP) but the cooking of sheet is better, these two kinds of materials all can tolerate 120 ℃ boiling and 135 ℃ thermophilic digestion.With the polypropylene is example, and polypropylene is a kind of polymeric material of vinyl in fact, and its material is a kind of crystalline material.Polypropylene material has low flammability, high strength, weatherability variability and good geometrical stability.It all has very strong resistance to oxidant, reducing agent and strong acid.But polypropylene is relatively poor to the barrier of oxygen and steam, and simple use polypropylene is difficult to the packing of product of obstruct demand as product external packaging.Therefore, be necessary the structure of existing punch forming package sheet material material is improved.
Summary of the invention
The objective of the invention is to overcome the defective that exists in the prior art, a kind of have the composite molding punch forming package sheet material material of high obstructing performance and the processing method of sheet material are provided.
For achieving the above object, technical scheme of the present invention has provided a kind of composite construction high-barrier resin forming sheet material, it is characterized in that: described sheet material comprises theca externa, tack coat and theca interna, theca externa and theca interna bond together by tack coat, described theca externa is for gathering dioctyl phthalate second diester sheet or polypropylene plastics tablet, theca interna is the multi-layer co-extruded film that contains barrier layer, and barrier layer is polyamide barrier layer or polyvinylidene chloride barrier layer plastic sheet.
Wherein: described tack coat is the aliphatic adhesive.
Optimized technical scheme is: described aliphatic adhesive is a dual-component polyurethane.
Optimized technical scheme is: described theca externa thickness is 200 microns～600 microns; Described theca interna thickness is 50 microns～250 microns.
Optimized technical scheme can also be: described theca externa thickness is 300 microns～500 microns; Described theca interna thickness is 80 microns～200 microns.
Optimized technical scheme is: described theca interna constitutes by three layers at least, and wherein middle one deck at least is a barrier layer.
Optimized technical scheme can also be: described theca interna is at least 5 layers, and described 5 layers are respectively polypropylene layer, tack coat, aramid layer, tack coat, polypropylene layer.
Optimized technical scheme can also be: described theca interna is seven layers to nine layers, described seven layers to nine layers theca interna are respectively polyethylene layer, polypropylene layer, polyethylene layer, tack coat, nylon barrier, tack coat, polyethylene layer, polypropylene layer, polyethylene layer constitutes, or be polypropylene layer, polyethylene layer, polypropylene layer, tack coat, nylon barrier, tack coat, polypropylene layer, polyethylene layer, polypropylene layer constitutes, or is polypropylene layer, polyethylene layer, polypropylene layer, tack coat, the polyvinylidene chloride barrier layer, tack coat, polypropylene layer, polyethylene layer, polypropylene layer constitutes.
In the present invention, the barrier property of high-barrier sheet material can be adjusted by the kind and the thickness that change barrier material.Secondly polyvinylidene chloride barrier property the best is polythene-ethenol, does barrier layer for nylon once more.
A kind of processing method of composite construction high-barrier resin forming sheet material is characterized in that: described processing method is to adopt downward-blowing water-cooling blown film method to make described multi-layer co-extruded film, or adopts the casting films method to make described multi-layer co-extruded film.
Advantage of the present invention and beneficial effect are: because the PP TYPE of barrier property excellence is applied to simple plastic sheet; its barrier property is significantly better than simple plastics; theca interna in this sheet ability is owing to adopt the production film process to produce; therefore the sheet material with same thickness contrasts; but the flexibility of the composite construction sheet material of this boiling is also had a clear superiority, therefore can realize multifunction, economized, environmental protectionization and cost optimization.Owing to adopted the method for producing film to produce sheet material, can make its sheet material have the characteristic of sheet material and film simultaneously in addition, this sheet just is that compound formable has soft characteristic again.
